Hi Guys,
I don't have an upload account here so I'll post a link to some shots made before and after my A7 conversion with three lenses:
- 24mm Elmar 3.8
- 35mm Summicron IV
- 50mm Summicron V (current, not APO)
The subject matter is boring, but useful. The folder contains a set of Full Frame images with each lens, before and after, at f5.6 (names start with FF) and crops of the upper left corner 1:1 as follows:
24mm Elmar - f3.8, f4, f5.6, and f8
35mm and 50mm Summicron - f2, f2.8, f4, f5.6, and f8
The file names should be self-explanatory. Focus was on the building in the center of the frame with each lens wide open.
Version IV of the 35mm Summicron isn't great in the corners on anything I have seen, but still interesting. I didn't correct for fall-off and the light was from the right, so the right-lower corner (I had the horizon cutting the corners) is a bit dark.
Lloyd's technique, subject matter, and use of an A7r provide a better test, but this should be informative. Also, my framing of the 24mm Elmar shots was off a bit, but the light was gone before I realized it. The Summicron's are pretty close.
If someone with an upload account on FM wants to pull them down and post here, it will make it easier for everyone.
