[reactan]

need top ask a question...thus if we use a DT lens on a APS-sized ccd, will the field of view be cropped as well?

eh.. no replies?

Hiee...React..

Using DT len son APS-C sized CCD D7D/D5D....will not have the problem as the image circle form by the DT lens covers the area larger than the CCD.

DT lenses are specially designed for APS-C size CCD DSLRs. If its cropped, KM can close shop liao.

so setting a DT lens at 40mm, the picture recorded equals a 40mm on film?

No... the image circle of the lens is still smaller than that of a full frame lens.

hmm, not really sure i understand what you mean... here are two possible answers:

a) DT lens at 40mm on a APS-C camera (1.5x crop) would give you a similar (not the same) picture as a picture taken on a film camera with a 60mm (40 x 1.5) full frame lens. the field of view would be the same, but if i'm not wrong, the APS-C picture will have a little more depth of field.

b) DT lens at 40mm on a film camera would give you the same picture as a 40mm full frame lens BUT because of the smaller image circle, the corners are likely to be black. (ie vignetting. see first post in this thread)
