So i just got my first legacy lens (and on the same day i received my adapter) so i was naturally stoked. It's been an hour reviewing the lens and i'm quite bummed now. Not quite sure but i think there's haze visible in the lens. I'm still not completely sure is it the light i'm shinning that's giving the haze or is it the lens itself. I was going by images posted by DeeJayK in the https://www.mu-43.com/f40/how-evaluate-used-lenses-23559/ also, it was only until the light in the dark room test that i was able to see the dust within the lens, on the inner elements. tried taking some pics with it, and it appears to work fine, but it's dark now so i was limited to taking pics within the poorly lit room, so i'll wait until daylight is available (tomorrow) to properly assess the actual shots. the aperture and focus ring seem fine, there's some (read: an ant could barely hear it) "grazing" when focusing, but nothing major. Also, there's no visible scratches on the outer part of the lens (maybe some micro ones but again, no major concern). I have not yet left the feedback to the ebay seller, but i'm not sure if returning is even worth it, the lens was 25$, the shipping 14$. If i ship it back, it's going to be at least additional 10-15$, i guess it's really not worth it... any advice? EDIT: probably a stupid question, but is it a problem if I adjust the aperture to any stop (apart from fully open) and the blades don't "come out" until i press one of the silver buttons on the lens? That's when the lens is not on the camera, on the camera it works.
