This morning I’ve found dust *IN* my lens, a Canon EF-S 17-55mm 2,8 IS USM. Of course this didn’t happen last night, but in a period of some months.
I’ve already recognized some dust particles during the last weeks, but they had no influence on what I was doing… but this morning I’ve tried to capture some stuff with my new Glidecam and recognized some lens flare effects. But there wasn’t enough sun to cause this… the reason for this: many small dust particles!
After some research I’ve found the website from Roger Cicala – and he managed to get rid of the “dust magnet syndrome”…
