Quote:Regarding vignetting, it seems some recents lenses often end up higher than older ones, although typicaly they grow in front end diameter.Yes that seems the trend, with noise and higher ISO becoming a non issue they seem to be relying more and more on digital correction that should be very easy for vignetting, better than that, it gives OEM lenses an advantage since the camera has the lens profile for JPG shooters.
This 24 mm Nikkor ends up close to 3 stops. For example old-new pair of Nikkor 35/2 vs 35/1.8 or Canon 35/2 old vs new show simikar patterns.
It is clear that bigger lenses allow better performance overall, flatter and higher MTF and better corrections. But vigneting? Is there some kind of trade-off correlation? Just curious.
Resolution OTOH can't be digitally corrected.
