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 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 β but is it a big enough upgrade to tempt owners of the original?
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 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.
