Whats in your bag??

I shoot with the D7100 and usually photo sports like cycling, running and football, i also photo landscapes, so my lenses are the Nikon 50mm F1.4, Nikon 18-140 F3.5 and a Nikon 70-200 F2.8, so would it be advisable to replace the 18-140 with a wider lens like a Tokina 11-16?

I'd keep the 18-140 and add the Tokina

What Jim said, though I'd personally add a Sigma 8-16mm.

I have the tamon 17-50mm f2.8 and the token 11-16 f2.8 before. I would recommend the token for landscape on the dx camera. It is wide and sharp.

Sorry, I am not sure why the words Tamron and Tokina failed to appear.

Hmmm... I have tamron SP AF17-50mm[h=1][/h]
