My wife needed a small travel camera and the smallest I had was Canon T70 with FD35/2 lens. I was checking if it works and was pointing at a lamp it in a dark room. I saw quite noticeable flare and removed the filter (very old Aroma skylight) and almost all of the flare was gone. Damn, I have been using that great lens almost 20 years with that sh** in front of it. Then I checked my EOS lenses. I cleaned the filters (UV) and made a similar check: I removed the filter but hold it in front of the lens. By slightly turning the filter in slightly different angles I tried to see if some of the flare "moves" when I move the filter. I saw that happen only on two of my EOS lenses: One had a 2 year old Tokina MC filter and the other one had an old and slightly scratched Canon filter. In the rest of my EOS lenses I had less then 2 years old B&W and Hoya multicoated filters (I don't exactly remember which Hoya versions but I think the two best models, maybe they are called HMC and Super HMC) and by looking through the viewfinder I didn't notice any problems. So from now on I know which filters to use. Those bad ones I will replace asap. Maybe also for you it is worth to make such a test especially if you photograph a lot in conditions with bright lights. I know some don't use filters at all but since the best ones don't seem to cause problems I will continue using them (the filters were dirty enough to discourage removing them). I also noticed it was difficult to clean some of the filters (maybe the new MC filters are more diffucult than the old ones). I had to press the micro fiber cloth more than I wanted to remove some of the dirt and I didn't completely succeed even then. I did brush and blow the filter first to get rid of the loose dirt. Any advice or similar experience?
