Originally posted by johnmflores I quickly took one into Photoshop and it processed quite nicely. A surprising amount of detail, sharp in the center, with just a little chromatic aberration along the edges. Very usable.
I agree. Plenty of detail to work with. CA not bad at all.
As good as the 50 1.2 is, it is a vintage lens that's not designed for corner to corner sharpness on high pixel density modern cameras.
I'd say it is a good performance by the speedbooster.
Now let's get some modern glass on there and see what we an do.
How about the the DA*300. It becomes a 150mm f/2 with a 700mm equiv FOV.
Or the DA 35mm Ltd. It becomes an 18mm f/1.4 with a 80mm equiv FOV.
Or the compact 21/40/70 pancakes...
