I have heard that Jakov is not going to buy this lens.
But seriously ... the wooden planks photo is a very clever test image and shows a lot of characteristics of the two lenses. The two do look very similar, but the 105 mm seems to have slightly higher central contrast, smoother rendition of the out-of-focus areas and a slightly more graceful transition from sharply focused to out-of-focus areas. I have an 85 mm f/1.8 AF-D which I like a lot, but it would not handle that transition from focused to out-of-focus nearly so nicely. I will wait patiently 5-6 years for the next-generation lens to come along, when some of these 105s will begin to appear on the used market ...
