I mentioned that one of the lenses I acquired recently is the M 150 3.5. Once I buy a precision screwdriver set, I'll try and clean the fungus from the inner elements... I'm a bit nervous about it to be honest.
I tested it again and most of the pictures had this "haze" in the middle due to the fungus. Here it is stopped down, f5.6 I think. I can tell it's sharp and I'm going to like the rendering of the lens once it's clean. Very much looking forward to it, but for now I have other lenses to keep me busy
By the way, this picture was one of the few that was salvageable by adding a TON of contrast and saturation that the fungus stole away...
