The other day we talked about the chance I took on an auction for an M 50mm 1.7 and an old Sears 100-300mm 5.6.

Just got the lenses today. Rushed a couple of snap shots for your review. No PP on the images. The first couple of shots showed smudges, which i have now cleaned off with a cloth.

50mm Images. wide open. Basic flat shot of tile.

100-300mm images. "wide" open. This is the lens I don't care about.

What do you see? Anything I am missing? Even the Sears lens seems pretty free from haze. Obviously, this is just a couple of simple shots. The DOF on the 50mm wide open is thin.

As I look at the 1.7, there is what looks like condensation around the very edge of the glass. You can't see it in the images, but it's there. It almost looks like adhesive residue. Probably around 50% of the front element edge.

Stuff near the front has less effect than stuff near the back. Dust specks have even less impact.

Take em outside (especially the Sears) and see what they can do
