I'm VERY VERY interested too in how 35mm nikkor lenses can cover 36mm by 36mm or 36mm by 48mm. Is the fall off acceptable ? is it possible to do any shot without stitching or must stitching be factored in ?
my basic experience using a lashed together system is that
basically the image circle covers about 17mp worth of a 22mp chip (which is good for me)
Because my test rig was home made I cant really comment on quality
I think lenses like the 28PC have good image circle (unshifted)
My 24 (1970s) has good image circle
17-35 and 20-35 look good
I would imagine that lenses with 'tighter design' (also with internal flare baffles) where they are pushing the optics like the 14 2.8 will not be so good but will still give a 11mp file with full 14 coverage in a way that no kinon can exept the SLRn
I will try and dig out my test shot - it is suprising
The plan would not be to stitch - stitching requires a bigger image circle when done 'flat'
I am trying to get away from stitching which can produce phoenomenal results if you have time - my clients dont have time
