So this weekend I picked up a secondhand EF 70-200mm f/4L lens from someone upgrading to the IS f/2.8 version. I took my camera with my when I visited L.’s friends farm and took about 250 shots.
Unfortunately, most pictures were garbage since I the UV filter that came with the lens is very smudged up. Most pics taken with the UV filter on have a very soft focus and were poorly exposed. I’m not sure how to clean the UV filter–maybe wash it with methanol and then air dry it?
These pics also had the ISO cranked needlessly to 1600. Ug.
