Oh, how ridiculous. You mention nothing of bokeh, MTF, micro-resolution or coma, not to mention lens 'character'. without doing side by side test with a Biogon against a USAF target how do you know that when making an incredible print that is adored the world over that it has not been comparatively ruined by virtue of not using the other lens? Oh, posts like this...
I have a Biogon and that makes prints which I find very pleasing, so clearly you are misguided about the asph. We can't both be right and I researched glass types before settling on mine - did you? Hmm? The silicon came from a part of Mongolia well known as the focal point of magnetic fields involved in the distortion of electron orbits within the Silicon deposited there. This clearly improves the character of the glass when shot of f2.8 due to subtle diffusive effects (which at f2 are less visible due to other optical deficiencies), which the asph lacks. A point I should make is that you only get this special glass if you buy Biogons between the serial numbers of 1033478 and 1033478 i.e Mine is the best and I would not trade it in even for an end to all humam suffering in this world (until I trade it in for a magic bullet next week).
What camera does the asph fit on?
