The lens rental guys did a tongue in cheek test some years ago, stacking up a crazy number of front filters,Įxaggeration is a good way to make a point, and the point is clear judging by the with and without 50 filters images.Ī wider view shows there is also a halo effect. Especially into the light where it had a tendency to flare, but I never really liked that lens, even before it got the scratch. You couldn't see it even at F22, but I always thought it an unsatisfying lens to use. Many years ago I had a Canon 24-105mm F4.0 which had a tiny scratch on the front element. The lens was a Canon 24-70mm F2.8L (the original version). I used a discarded Pec Pad and Elipse fluid to clean the filter, and all was well. It got to where I couldn't anything on the sensor, but he was still some significant spots at F22, so I asked if I could have a look, and found that the lens protecting filter had potatoes growing on it - or could have done. My tool kit contains an Arctic Butterfly static brush, Pec Pads and Elipse Fluid (two types), and my magic weapon which is 7X illuminated loupe. I found this old thread while looking for PSD vs TIFF threads.Ī few days ago a local PJ buddy bought his (the paper's) camera round for me to clean the sensor. You've all seen the tourists with huge 70-200 zooms dangling on their bellies? And how they all have the lens hood permanently attached, in the reversed (flipped back) position where it serves absolutely zero purpose? Do they ever wonder what it's for.? I put a glass filter on and let that take the beating. You need to take the lens cap off before taking a picture ![]()
