The Rodenstock 75mm f4 Apo is used on bellows here to show, again, how very crude real life is. This lovely gold-plated stereo jack turns out to be very coarse and inaccurate (especially compared to the Minolta engraving which is many times magnified compared to this). Used on the Nikon D200, the 75mm Rodagon on bellows had terminal central flare - a big patch of reflected light. On the Alpha 100, even with this studio table background, there is no internal reflection. Sony seem to have really sorted the coating of the AA filter to eliminate bounced light.
