It’s often said that any camera is only as good as the lens you put on the front of it. Recent FX (full-frame) format Nikon bodies like the D810 and D850 certainly set the bar high, with high-pixel-count sensors that draw attention to any shortfall in sharpness. But there’s more to a good lens than just its ability to resolve fine detail.

Handling is a key factor in how a lens performs in real-world shooting. You’ll need fast and accurate autofocus, to ensure you nail defining moments in anything from a fleeting expression in portraiture to action sports and wildlife photography. In handheld shooting, effective optical stabilization can make the difference between capturing images that are fit for a gallery, or just fit for the bin.

Increasingly, shortfalls in various aspects of image quality can be corrected in-camera

Even outright image quality is about much more than mere sharpness. Good contrast is highly desirable, even when shooting wide-open at the largest available aperture. Other attributes we tend to look for are minimal distortion and color fringing, good resistance to ghosting and flare, and reasonably low vignetting (darkened image corners). Increasingly, shortfalls in various aspects of image quality can be corrected in-camera, or in post-processing, but that’s a poor substitute for great optical quality.

Nikon or third-party?

Other facets of image quality are harder to quantify, like ‘bokeh’ (the attractiveness of defocused areas within images). It’s a critical aspect of performance for ‘fast’ lenses that enable a tight depth of field as well as enabling you to retain moderate shutter speeds even under dull lighting without the need to really push your camera’s ISO setting.

It’s certainly not always the case that own-brand Nikon lenses outperform competitors from independent manufacturers like Sigma and Tamron. Indeed, some of the latest lenses launched by independent companies are simply superb, and there are some serious bargains to be had.

Based on our extensive lab tests and ‘real-world’ testing, we’re proud to present our top 10 lenses in a wide range of popular categories, as well as great-value alternatives to suit tighter budgets. Let’s take a closer look at all the winners.

Wide-angle zoom: Sigma 12-24mm f/4 DG HSM | A

The new king of super-wide viewing angles

Type: Zoom | Sensor size: FX | Focal length: 12-24mm | Maximum aperture: f/4 | Image stabilizer: No | Weather seals: Yes | Minimum focus distance: 0.24m | Filter size: None | Dimensions: 102 x 132mm | Weight: 1,150g

Supreme viewing angles
Premium build and image quality
No filter attachment thread
No optical stabilizer

You have to go some to beat Nikon’s legendary AF-S 14-24mm f/2.8G ED ultra-wide zoom, but that’s exactly what Sigma has done with this spectacular lens. Like its predecessor, it boasts a class-leading maximum viewing angle, thanks to an incredibly short minimum focal length for an FX format zoom. However, the new ‘Art’ lens has upgraded optics with an extra-large-diameter aspherical element at the front and five top-notch FLD (Fluorite-equivalent Low Dispersion) elements. Fluorine coatings are applied to the front and rear elements, and the mounting plate gains a weather-seal ring. The autofocus system is revamped and noticeably faster, and the new lens switches to a constant-aperture design. From an image quality standpoint, sharpness and control over distortion are excellent, and represent considerable improvements over the previous edition. As with many ultra-wide lenses the hood is built-in, offering physical protection to the bulbous front element. However, this means you can’t easily fit filters, unless you go for a system like the Lee Filters SW150 Mk II.

Great-value option: Tamron SP 15-30mm f/2.8 Di VC USD

It’s not quite as ultra-wide as the Sigma, but this Tamron undercuts it for cost, while adding optical stabilization and a faster f/2.8 aperture rating.

Wide-angle prime: Sigma 20mm f/1.4 DG HSM | A

The widest f/1.4 prime in Sigma’s current range of Art-line lenses

Type: | Sensor size: FX | Focal length: 20mm | Maximum aperture: f/1.4 | Image stabilizer: No | Weather seals: No | Minimum focus distance: 0.28m | Filter size: None | Dimensions: 91 x 130mm | Weight: 950g

Excellent build and image quality
Wide f/1.4 aperture rating
No filter attachment thread
No optical stabilizer

Sigma’s ‘Art’ lenses are designed to unleash photographers’ creative potential, delivering excellent image quality and fast aperture ratings. There’s a large selection of f/1.4 primes to choose from in the range, including 20mm, 24mm, 35mm, 50mm and 85mm lenses. This 20mm lens is not only the widest-angle f/1.4 optic in the group (there’s also a 14mm f/1.8 lens), but is remarkable for combining such a wide aperture with such a short focal length. The no-compromise design and superlative image quality are enabled by an extra-large-diameter aspherical lens; this makes for an undeniably chunky and heavy build, but it’s a beast of a lens.

Great-value option: Irix 15mm f/2.4 Firefly

It lacks autofocus, but this is a fabulous manual-focus lens that’s beautifully built and a real joy to use. The ‘Blackstone’ edition adds a couple of extra luxuries, but the Firefly is unbeatable value.

Standard zoom: Nikon AF-S 24-70mm f/2.8E ED VR

For a standard zoom, it’s anything but ‘standard’

Type: Zoom | Sensor size: FX | Focal length: 24-70mm | Maximum aperture: f/2.8 | Image stabilizer: Yes | Weather seals: Yes | Minimum focus distance: 0.38-0.41m | Filter size: 82mm | Dimensions: 88 x 155mm | Weight: 1,070g

Full pro-grade build quality
Fast and constant f/2.8 aperture
Big and heavy for general shooting
Very noticeable vignetting

This lens literally dwarfs most standard zooms, but at least the physical length remains fixed throughout the zoom and focus ranges. It builds on the success of its predecessor, adding Vibration Reduction and improving the optical path and build quality. Enhancements include four ED elements, an HRI (High Refractive Index) element, Nano Crystal Coat, fluorine coatings on the front and rear elements, and an electromagnetically controlled diaphragm. Image quality is excellent in most respects, although color fringing can be noticeable if uncorrected, and vignetting is quite severe at f/2.8.

Great-value option: Tamron SP 24-70mm f/2.8 Di VC USD G2

The G2 (Generation 2) edition of Tamron’s 24-70mm lens combines excellent image quality with a tough build and great handling. The original edition is still on sale as well, and rather less expensive to buy.

Standard prime: Tamron SP 45mm f/1.8 Di VC USD

Who says you don’t need stabilization on a standard prime?

Type: Prime | Sensor size: FX | Focal length: 45mm | Maximum aperture: f/1.8 | Image stabilizer: Yes | Weather seals: Yes | Minimum focus distance: 0.29m | Filter size: 67mm | Dimensions: 80 x 92mm | Weight: 540g

Optical stabilizer
Premium build and image quality
Expensive for an f/1.8 prime
Not as fast as f/1.4 rivals

Our top choice of ‘portrait prime’ for DX-format DSLRs is also our favored standard prime for FX cameras. Compared to the excellent Sigma 50mm f/1.4 Art lens, the Tamron loses two-thirds of an f/stop in aperture rating, but is a much more manageable size and weight, and gains optical stabilization. You could argue that you don’t really need stabilization in such a ‘fast’ lens, but we disagree. Standard primes are often used in preference to zoom lenses, for their excellent sharpness and minimal distortion, not just for their faster apertures. You might well want to dial in a medium or narrow aperture setting to extend the depth of field, so stabilization can be a big help in handheld shooting.

Great-value option: Nikon AF-S 50mm f/1.4G

Compared with the ‘budget’ Nikon AF-S 50mm f/1.8G, this f/1.4 lens is about twice the price, but still rather less expensive than the Tamron. It’s nice and sharp, but you do forego stabilization.

Superzoom: Nikon AF-S 28-300mm f/3.5-5.6G ED VR

It’s convenient, if not especially travel-friendly

Type: Zoom | Sensor size: FX | Focal length: 28-300mm | Maximum aperture: f/3.5-5.6 | Image stabilizer: Yes | Weather seals: Yes | Minimum focus distance: 0.5m | Filter size: 77mm | Dimensions: 83 x 115mm | Weight: 800g

Big zoom range
Good build quality
Big and heavy
Image quality is underwhelming

Superzooms for DX-format cameras are often referred to as ‘travel lenses’ because they deliver a big zoom range, stretching from wide-angle to telephoto focal lengths, usually in a fairly compact and easily manageable package. This avoids the need to carry more than one lens if you’re trekking around the city, or flying to the other side of the world. The travel-friendly theme is somewhat lost in the FX-format camp, however, and this superzoom tips the scales at 800g. Even so, it’s a useful lens for event photography and other times you need to quickly and repeatedly switch between wide-angle and telephoto shooting. As is often the case, the extended zoom range comes at the cost of compromised image quality – in this case it’s good rather than great, with mediocre sharpness and severe distortions and vignetting.

Great-value option: Tamron 28-300mm f/3.5-6.3 Di VC PZD

It’s a cheaper option than Nikon’s FX-format superzoom and delivers similar image quality, but the autofocus system is comparatively basic and build quality doesn’t feel quite as good.

Portrait prime: Tamron SP 85mm f/1.8 Di VC USD

Impressive sharpness combined with sumptuous smoothness

Type: Prime | Sensor size: FX | Focal length: 85mm | Maximum aperture: f/1.4 | Image stabilizer: Yes | Weather seals: Yes | Minimum focus distance: 0.8m | Filter size: 67mm | Dimensions: 85 x 91mm | Weight: 700g

Superb image quality
Stabilized and reasonably compact
Narrower max. aperture than some
No pouch or soft case supplied

There are some fabulous 85mm f/1.4 portrait lenses on the market, including Nikon’s own AF-S 85mm f/1.4G and Sigma’s 85mm f/1.4 DG HSM | A. This Tamron can’t quite compete on aperture rating but adds optical stabilization, which is lacking in the other two lenses. It’s also significantly less expensive to buy. While the slightly narrower maximum aperture might seem to give the Tamron a disadvantage when it comes to blurring the background in portraiture, the lens actually produces a wonderfully smooth bokeh, while maintaining excellent sharpness at the point of focus. For indoor portraiture without flash, or for handheld shooting in low-light conditions, the stabilizer is well worth having, even when using a very wide aperture; it’s even more of a benefit when using narrower apertures for extending the depth of field, to put portrait sitters into the context of their surroundings.

Great-value option: Nikon AF-S 85mm f/1.8G

This Nikon lens is a bargain if you’re willing to stick with f/1.8 rather than stretching to an f/1.4 aperture, although it doesn’t feature stabilization.

Macro prime: Tamron SP 90mm f/2.8 Di VC USD Macro

A master macro lens that outperforms Nikon’s 105mm VR offering

Type: Prime | Sensor size: FX | Focal length: 90mm | Maximum aperture: f/2.8 | Image stabilizer: Yes | Weather seals: Yes | Minimum focus distance: 0.3m | Filter size: 62mm | Dimensions: 79 x 117mm | Weight: 610g

Hybrid optical stabilization
Top-grade construction
Pricier than some rivals
No pouch or soft case supplied

Almost as expensive as Nikon’s popular Nikon AF-S 105mm f/2.8 G IF ED VR Micro lens, the latest edition of this Tamron classic includes a revolutionary hybrid optical stabilization system. Essentially, this can counteract shift in the vertical and horizontal axes, as well as angular vibration or wobble, which gives superior stabilization, especially for close-up shots. In our tests, the Tamron proved a little sharper than the Nikon, especially for extreme close-ups, while defocused areas look a little smoother.

Great-value option: Sigma 105mm f/2.8 EX DG OS HSM Macro

It lacks the Tamron’s hybrid stabilization system and weather seals, but has refined handling and delivers superb image quality.

Budget telephoto zoom: Nikon AF-P 70-300mm f/4.5-5.6E ED VR

A classic Nikon telephoto zoom, reinvented

Type: Zoom | Sensor size: FX | Focal length: 70-300mm | Maximum aperture: f/4.5-5.6 | Image stabilizer: Yes | Weather seals: Yes | Minimum focus distance: 1.2m | Filter size: 67mm | Dimensions: 81 x 146mm | Weight: 680g

Good weather-sealed build quality
Impressive performance
Expensive for a ‘budget’ lens
Physical length not constant 

Nikon’s pre-digital-age 70-300mm ED lens was hugely popular, and the later VR edition has long been a favorite with DSLR shooters. It’s now been replaced by this lens, which features much of Nikon’s latest technology, including an AF-P (Pulse) autofocus system based on a stepping motor. This delivers rapid performance for shooting stills, along with smooth and virtually silent focus transitions for movie capture. It also features an electromagnetically controlled diaphragm, for more consistent apertures in rapid-fire shooting using fast continuous drive mode. On top of that, you get Nikon’s recently introduced Sport VR mode, which makes it easier to track erratically moving subjects in the viewfinder. However, the AF-P autofocus and electromagnetic diaphragm control make the lens incompatible with some older DSLRs, and the relatively expensive price tag stretches the notion of a ‘budget telephoto zoom’.

Read our in-depth Nikon AF-P 70-300mm f/4.5-5.6E ED VR review

Great-value option: Tamron SP 70-300mm f/4-5.6 Di VC USD

As well as being our top pick for DX-format cameras, thanks to its good performance and relatively inexpensive price, this Tamron is also a smart budget buy for FX bodies.

Fast telephoto zoom: Nikon AF-S 70-200mm f/2.8E FL ED VR

It’s simply the best fast telephoto zoom on the planet

Type: Zoom | Sensor size: FX | Focal length: 70-200mm | Maximum aperture: f/2.8 | Image stabilizer: Yes | Weather seals: Yes | Minimum focus distance: 1.1m | Filter size: 77mm | Dimensions: 89 x 203mm | Weight: 1,430g

Spectacular image quality
Excellent build quality and optics
Typically heavy
Fiendishly expensive

The go-to telephoto for most professionals, a 70-200mm f/2.8 lens gives you good telephoto reach, and retains a respectable f/5.6 aperture rating at up to 400mm when used with a 2x teleconverter. Top tricks include auto and manual priority autofocus options, a Sport VR mode, and an electronically controlled diaphragm, all of which are also featured in Nikon’s new 70-300mm ‘budget’ telephoto zoom. This top-flight lens is supremely well built, however, more suited to professional use. The autofocus system is super-fast and image quality is stunning, with incredible contrast and sharpness.

Great-value option: Tamron SP 70-200mm f/2.8 Di VC USD G2

This directly competing second-generation Tamron’s 70-200mm f/2.8 lens is very nearly as good as the own-brand Nikon, but costs about half the price.

Super-telephoto zoom: Sigma 150-600mm f/5-6.3 DG OS HSM | S

It really puts the ‘super’ into super-telephoto

Type: Zoom | Sensor size: FX | Focal length: 150-600mm | Maximum aperture: f/5-6.3 | Image stabilizer: Yes | Weather seals: Yes | Minimum focus distance: 2.6m | Filter size: 105mm | Dimensions: 121 x 290mm | Weight: 2,860g

Smart features and build quality
Outstanding performance
Handheld shooting a challenge
Typically narrow aperture at 600mm

Despite significantly undercutting the popular Nikon AF-S 80-400mm f/4.5-5.6G ED VR for price, this Sigma ‘Sport’ lens delivers 50% more telephoto reach and packs a real punch in terms of performance. Rarely for a Sigma lens, it features a full set of weather seals, and there’s no shortage of high-tech treats. Auto and manual priority autofocus modes are available, and the clever zoom lock mechanism enables you to lock the position at any marked focal length, rather than just at the short end of the zoom range. Excellent contrast and sharpness are retained all the way to the maximum 600mm focal length, distortions and color fringing are very well controlled, and the ring-type autofocus system does well to keep up with even fast-moving subjects.

Great-value option: Sigma 150-600mm f/5-6.3 DG OS HSM | C

Nearly a kilogram lighter in weight, this Contemporary lens retains many of the advanced features of the Sport edition, but is cheaper to buy and less of a strain in handheld shooting.

With two screens and seriously long battery life the Ticwatch Pro is no ordinary smartwatch, yet it has most of the usual features you’d expect on top of that, including a touchscreen and Wear OS software.

That could combine to make it one of the most interesting wearables we’ve seen, assuming it all comes together into a cohesive gadget.

Previously announced in China, the Ticwatch Pro is now officially coming to other countries including the US, UK and Australia. Read on below for a full introduction to what the Ticwatch Pro smartwatch will offer you if you decide to buy it soon.

Cut to the chase

  • What is it? A Wear OS watch with two screens
  • When is it out? Announced in May 2018, you can buy it now
  • What will it cost? Pricing is set at $249.99 / £219.99 / AU$369.99

Ticwatch Pro release date and price

  • Announced in China in May 2018
  • Officially on sale in US, UK and Australia on June 10, 2018
  • Set to cost $249.99 / £219.99 / AU$369.99 

First off, back in May 2018, Mobvoi announced the Ticwatch Pro for those in China and there wasn’t any word on worldwide availability.

The latest news is the watch is on sale in the US, UK and Australia, with a few other countries joining it. If you live in the UK or US, you’ll need to head to Amazon to be able to buy the watch and if you want it soon you’ll have to be an Amazon Prime member.

It’s exclusive to Amazon Prime in both countries until August 15. From then until September 30, it’ll be an Amazon exclusive product but you won’t have to be a subcriber to the Prime service to be able to buy it. Those in Australia can buy it from the official Mobvoi website starting today.

This is cheaper than a lot of other high-end smartwatches though with Mobvoi specializing in wrist tech that doesn’t cost that much money but comes with a premium design.

Pricing for the Ticwatch Pro is $249.99 / £219.99 / AU$369.99, but we may see that fluctuate over time. That’s more than both the Ticwatch S and Ticwatch E cost, but it’s not as much as other high-end Wear OS watches like the LG Watch Sport.

Ticwatch Pro design and display

  • 1.4-inch 400 x 400 OLED main screen
  • Low power FSTN LCD secondary display
  • Water-resistant with an IP68 rating

Let’s start with the screen, because that’s by far the most interesting part of the Ticwatch Pro. And that’s because there’s two of them.

You get both a circular OLED touchscreen, which is fairly standard for a smartwatch, and a low power black and white FSTN LCD display, which sits on top of the OLED screen.

That second screen is transparent when it’s not in use, so you’ll only ever be looking at one screen at a time. In most cases that will be the OLED one, and you’ll get a standard Wear OS experience.

However, when you’re not actively using the TicWatch Pro (for example when it’s just sat idle on your wrist), it will switch to the LCD display, allowing you to still see the time and certain other information while consuming far less power. You can also just use the LCD screen on its own for serious power-saving, but we’ll discuss that more in the battery section below.

The TicWatch Pro has a low power screen on top of its main one

The OLED screen is 1.4 inches with a resolution of 400 x 400, making it fairly large and sharp. The watch has what Mobvoi calls a “premium build quality” as it has bezel and rear cover that’s covered in stainless steel.

The rest of the case is made of hard nylon reinforced with glass fibre. You also have eight different strap choices for the Ticwatch Pro with an orange or black choice if you’re looking for an entirely silicone choice.

There are also five straps with genuine Italian leather on the outside and silicone on the inside, so you can take them running without ruining the design. Those come in black, black with a silver buckle, orange, brown and black with an orange inside.

If you just want a leather strap, there’s a brown one with a silver buckle available.

In all it looks to be going for a classy appearance, rather than a sporty one. It comes in at 12.6mm thick and 58.5g. It’s also IP68 certified, which means it can be submerged up to 1.5 meters deep in water for up to 30 minutes – so it can survive the rain, but you shouldn’t take it swimming.

Ticwatch Pro features and specs

  • Heart rate monitor, NFC and GPS
  • Snapdragon Wear 2100 chipset with 512MB of RAM

The Ticwatch Pro may look like a fashion-led watch, but it comes with a heart rate monitor, GPS and step tracking skills. It also has NFC, so you’ll be able to use the watch to make contactless payments through Google Pay.

The TicWatch Pro has some fitness features, including a heart rate monitor

Apparently, the US might also get a model with LTE included, which could allow you to use the watch in full while leaving your phone at home, but this isn’t confirmed and it’s not clear whether anywhere else will get a version with LTE.

Considering we’ve now got an official release about the launch in the US, we don’t expect the LTE version of the watch will be coming anytime soon… if at all.

As for the specs, the Ticwatch Pro has a Snapdragon Wear 2100 chipset, 512MB of RAM and 4GB of storage, all of which are standard smartwatch specs.

TicWatch Pro OS and battery

  • Runs Wear OS, previously called Android Wear
  • Includes a 415mAh battery
  • Around 2 days of life with normal use or up to 30 in Essential Mode

The Ticwatch Pro runs Google’s Wear OS, so at its core you should get much the same experience as you do on the majority of smartwatches.

Battery life is likely to be far better than most rivals though, as its ability to switch to a low power screen when not in use means it should apparently get around two days of battery life from its 415mAh juice pack.

When not in Essential Mode, the TicWatch Pro runs Wear OS

When not in Essential Mode, the TicWatch Pro runs Wear OS

That’s good, but no better than the likes of the Samsung Gear S3. However, where the Ticwatch Pro could really win out is in its ‘Essential Mode’, which completely shuts down Wear OS, leaving you with access to only the basic FSTN LCD display.

Starting up Wear OS again from here apparently takes around a minute, so it’s presumably a similar process to rebooting the watch, but even in Essential Mode you can still see the time and track your steps and heart rate, and by using this mode you can apparently get up to 30 days of battery life from the TicWatch Pro.

Apparently additional features will be added to Essential Mode over time, but for things like notifications and contactless payments you’ll have to switch Wear OS back on.

Mere hours after Microsoft teased its upcoming Surface device on Twitter, the company has unveiled its newest and cheapest entry in the range – the Surface Go.

With a thickness of just 8.3mm and weighing in at 1.15 pounds (520g), the 10-inch Surface Go is aimed at portability and could be perfectly placed to take on Apple’s own cheaper iPads, with Microsoft seemingly targeting the same student demographic that Apple’s recently been chasing.

The Go is powered by an Intel Pentium Gold 4415Y processor and comes in either a 4GB RAM, 64GB storage configuration or 8GB RAM, 256GB storage for $399 (AU$599 / £TBA) or $549 (£TBA / AU$TBA) respectively.

Further specs

The Surface Go’s display offers support for Microsoft’s existing Surface Pen stylus (priced at $99) including its 4,096 levels of pressure sensitivity, and like other Surface devices uses a 3:2 aspect ratio – in this case, with a resolution of 1,800 x 1,200 pixels.

While the Go includes Microsoft’s proprietary Surface Connector for charging and dock connections, you can also charge this smaller unit via its USB-C 3.1 port, which (as you’d expect) can also be used to plug in external accessories.

As it’s intended to to be used on the move, the Surface Go’s battery should get you up to 9 hours of usage, according to Microsoft, thanks to the efficiency of the Pentium Gold processor and Windows 10 S combo. Users can upgrade to the full Windows 10 for free if they wish, although that’ll likely mean taking a hit in battery life.

Accessories and pricing

The availability of accessories globally is yet to be confirmed, but you’ll be able to get a black Surface Go Type Cover for $99, with red, blue or silver “Signature” Alcantara Type Covers costing $129.

There’s also a new Surface Mobile Mouse for $34.99, which will be available in the same red, blue, or silver color options as the Signature Type Covers and the existing $99 Surface Pen.

Pricing will start from $399 / AU$599 (we’re working to confirm UK pricing) and the devices will be available for pre-order from Wednesday 11 July globally. The US will see the Surface Go land August 2, while Australia and New Zealand will get it August 28.
