Are there any significant OPTICAL differences between the F1.4D an dF1.4G (newer) versions of the 85m lens?? The lens hood mount is different Screw on the old, bayonet on the new. If the lenses are different - is the difference noticeable 1) on a large print 2) when projected using a data projector? The dollar$ for the newer lens are significantly higher.
Thanks for the advice.
