Jonas asked in another thread:
The lens with the adapter ("K&F Concept" from China) with a self cobbled APO Componon 60/4 and an adapter mounted Contax G 90/2.8. All lenses have proper lens hoods fully deployed.
As is apparent, the size of the AA 75/2 is just "perfect".
How the lenses look from the rear (what the sensor sees):
The APO Componon and the Contax lenses look fine due to proper shields (no shiny bits). The AA 75/2 shows that shiny metal that Leica are so proudly showing of as the best feature of their fine cameras () like Leica T.
It does not look bad.
Upclose when the lens is focused away from infinity:
More of that machine work is shown off to the sensor. :-)
The lens (optics) is superb but that shiny metal innards are a problem when used like this. If someone is going to use the lens exclusively for Sony E and want the best out of it, then it needs a lit bit of work to shield those glistening metal parts.
How APO is APO? That is a not a simple question.
The APO Componon (aka, APO Makro Componon, Macro Digitar, APO Macro Digitar) is a good lens. If that is taken as a reference, the AA 75/2 is a bit more APO than that.
The AA 75/2 bleeds a bit of long wave UV but is of NO concern on an A7r and such since their sensors see 0% UV. Film folks were not too thrilled with this lens or its bokeh (unlike the fuzzy smooth Mandler lenses) but AFIAC, it is just superb on digital (especially Sony A7r). The built lenshood is awesome. One can use ND filters (I do) with beneficial results.
I have posted many pictures using this lens on A7r here. I don't do any side by side comparisons.
