[QUOTE="Zimboy, post: 189215, member: 15987"] Ah, it's good to know that the Dx mode actually does have an effect on the DoF. When I asked the salesman if one can get around this issue with the Dx crop mode he answered no and that it would be just as useful to simply crop the image in post processing. I understand where he's coming from cos it's still the same sensor, same pixels, same glas & optics, just that one uses less of it in Dx mode, hence the DoF should be identical. Yet you say when in Dx mode you can have more reach hence greater DoF, that's good to know. Is there much difference between Dx mode on an Fx, and a real Dx sensor? (OK that's a silly question, I know.) Oh by the way, would using a teleconverter also help get around this problem? By gaining that extra reach, more DoF - would make sense. Then one would also have a "virtual" 210m lens. Yes I know one would loose light but maybe it's worth it? Greetings, Zimboy [/QUOTE]
