I am planning to buy a D7000. If I would like to protect my investment on the glasses for a FX camera that I may buy later, should I buy FX lenses instead of DX lenses?
I understand that DX lenses would generate vignettes in a FX format camera hence not 'usable'. However, I understand that FX lenses can be used in D7000(DX). Would the result be as good as using a DX lense.
BTW, I am returning to photography after ages. I used a F2S extensively (20 years back) and a N70 for a brief stint. Never used a DSLR. Thanks for your patience!
It's true that, in general, lenses designed for FX or 35mm film format will work on a D7000 camera. But there are a few factors to consider...
Some "FX" lenses are older designs, and there may be a newer DX design that offers improved performance. One example is the (FX) AF 35mm f/2D, which is from 1995 and is less good in most ways than the AF-S DX 35mm f/1.8G.
Wider-angle FX lenses tent to be of lesser zoom range and are typically larger, heavier and more expensive than a DX alternative. The widest-range superwide FX zoom Nikkor is the AF-S VR 16-35mm f/4G, whereas in DX we have the AF-S DX VR 16-85 f/3.5-5.6G
Thanks Paignton. So price performance wise, I maybe better off with the DX lenses, at least for now. As I am reviewing more and more comments, it seems DX sensors may have enough punch as a FX for all practical purposes and I may never have to buy a FX or even larger format Body ( Like a Mamiya) unless I get into extreme enlargement.
I agree - I think it's a mistake to automatically assume that a FX camera is right (or necessary) for everyone. Many, many people - including some great photographers pro and amateur - produce wonderful prize winning images with today's DX cameras.
The DX format will not be disappearing anytime soon!
