Unsure of your wideangle zoom options? We've picked out a selection of the best zooms that are available in a range of different lens mounts.
Nikon 14-24mm lens and the Canon 16-35mm lens
Sony 16-35mm lens and the Nikon 10-24mm lens
For Sony A-mount users there is the 16-35mm f/2.8 ZA SSM Vario-Sonnar T lens (£1,349) and there's a good selection of full frame wideangle zoom lenses offered by third-party manufacturers such as Sigma, Tamron and Tokina.
For APS-C DSLRs Nikon produces the 10-24mm f/3.5-4.5G SF-S DX lens (£644)
Pentax 12-24mm lens and the Canon 10-22mm lens
For Canon users there's the EF-S 10-22mm f/3.5-4.5 USM lens (£624) that is equivalent to 16-35mm in 35mm terms.
For Pentax DSLRs there's the 12-24mm f/4 ED AL (IF) lens (£799) and as well as these suggestions you'll find that many third-party manufacturers cater for the APS-C format.
Sigma 10-20mm lens and the Panasonic 7-14mm lens
A popular lens choice is Sigma's 10-20mm f/4-5.6 EX DC HSM, which can be picked up in a variety of lens mounts for £369.
Not forgetting the compact system camera area of the market and the Micro-Four Thirds system, Panasonic produces a 7-14mm f/4 Lumix G lens that's equivalent to 14-28mm. Costing £999 it is fairly expensive, however, and if your budget can't stretch to this there's also the Olympus 9-18mm f/4-5.6 M.Zuiko ED lens at £499. Though it's half the price it isn't as wide as Panasonic's offering and has a 35mm equivalent focal length of 18-32mm.
