David, relevant and topical thread

Good thread David, and not unlike the one I started here:


I think Canon stuck at 8.2mp for the 30D because:
a) of higher production cost (which will be overcome),
b) of negligible quality gains, ie noise (which probably will be overcome),

c) 8.2m on an APS-C sensor is more resolution than most lenses can deliver with good clarity (which will be improved upon, but not quickly or easily),

d) if you factor all these things around a maximum print size of 10-12in long, at normal viewing distances you cannot actually see any greater detail than 300ppi (ie total 6-8mp) so what's the point? (You've hit the buffers here, unless we all get bionic eyes.)

All of which suggests to me that the 1.6x APS-C sensor has a long and propsperous future for those people who are very happy with medium-medium/large prints, and have a sensible attitude to budget. APS-C is the new '35mm film'. 10mp is a sensible limit for the foreseeable future.

On the other hand, a full-frame sensor has about three times the area of APS-C, which means more - bigger and better - pixels. The image requires substantially less enlargement, and this gives the lenses more of a chance to deliver. FF is the new 'medium format' for pros, specialists and gear-heads. 20mp is almost here in FF, and already promises good noise levels and dynamic range. Image sharpness, contrast and colour will be stunning.

I don't think the future is any more complicated than that, and it looks pretty rosy to me

Best regards,


PS 1.3x sensors were always a stop-gap and will die.
