Hi all.
I have an 18-70mm AF-S Nikkor 3.5-4.5 G ED kit lens that came with my D70s. It's a DX lens.
I also have a Sigma 70-300 4-5.6 DG. I assume it's a DX lens???
(here it is: http://www.jessops.com/online.store...(Nikon AF Including D40D40x) -73537/Show.html)
When I look through the Nikon lens at 70mm I see a considerably wider view than when I look through the Sigma at 70mm. I have a funny feeling that the Nikon is about 1.4 times wider...
I'm missing something stupid, and I know it must be to do with DX format, but I don't understand why.
Could someone enlighten me please.
Thanks.
