The mark II version of Nikon's 70-200mm f/2.8 for Z-mount features a lighter build, new optical design and various design tweaks, and the result is a virtually flawless telephoto zoom.

The Canon RF 45mm F1.2 STM impresses with its super-wide aperture and affordable price - this lens has its issues, however.

Viltrox's take on the classic 85mm f/1.4 professional portrait lens is a huge success, and it's excellent value too

I paired the Viltrox AF 28mm f/4.5 lens with a full-frame Nikon mirrorless camera, and was surprisingly fond of the tiny and cheap optic

The Sigma 135mm f/1.4 DG | A is the world’s-first 135mm prime with an f/1.4 aperture and replaces its nearly decade old predecessor.

The Sigma 12mm f/1.4 DC | Contemporary is the only mirrorless APS-C lens to simultaneously boast a wide 12mm focal length and bright f/1.4 maximum aperture – all wrapped up in a light and portable package.

The Sigma 17-40mm f/1.8 DC | Art builds on the success of the 18-35mm f/1.8 which made its debut back in 2013 and improves on it in virtually every way.

The Sony FE 100mm f/2.8 Macro GM OSS is the update to its 10-year-old predecessor, and it's the lens Sony macro lovers have been dreaming of.

The Z 24-70mm f/2.8 S II is Nikon's first second-gen Z-mount lens, with a new optical design, slimmer profile and internal zoom – but is it a big enough upgrade to tempt owners of the original?

The Lumix S 100-500mm F5-7.1 O.I.S is an ultra-telephoto with great reach and superb stabilization.

The OM System 50-200mm is the world's first 100-400mm equivalent zoom lens with f/2.8 aperture. Together with a current OM System camera, it's a true wildlife and sports photography master.

The Viltrox AF 35mm f/1.2 LAB FE is an impressive lens in every way, and comes in at an amazingly attractive price you may not be able to resist.

The Viltrox AF 16mm f/1.8 FE is an impressive ultra-wide-angle prime lens that offers pro-grade performance and image quality at an affordable price.

The Sigma 56mm F1.4 is the longest telephoto option of a quartet of Contemporary DC DN F1.4 primes, with an effective 85mm focal length. For me, it's the best buy of the bunch, able to create dreamy portraits.
