Which should I buy for my D7100? Sigma 18-35mm f/1.8? Tamron 24-70mm f/2.8? Or Sigma 24-105mm f/4?
Chris says… It depends on whether you want a wider aperture or a longer range – and on what you want to shoot.
You say you would like to become a commercial photographer. This makes the decision easier. The Sigma 18-35mm f/1.8 is an innovative zoom lens, but it is not compatible with FX SLRs, and as you may well want to get one of those if you go more pro, I would give this a miss. The Sigma 24-105mm is only a tad faster than a kit lens, so I’d opt for the Tamron 24-70mm f/2.8. It is great on both DX and FX bodies, and has a pro-spec maximum aperture. Also, unlike Nikon’s more expensive alternative, it has built-in image stabilisation. It came out top in our round up of luxury kit lenses in Issue 26.
