Dropped my 100-400. It didn't have a filter on it so no broken filter and no scratches on my lens.
Does puzzle me why people use UV filters instead of a clear filter. UV filters have a coating to eliminate UV, which is totally unnecessary as digital cameras aren't affected by UV. So you are putting an unnecessary lens coating between your camera and the scene. If you do want a protective filter (that will scratch your lens instead of protecting it) wouldn't a simple/non-UV one be better?
When I bought the one that was on my Sigma 20-40 when I dropped it, which was a Hoya Pro 1 Digital, the only option in an 82mm filter was UV, which should technically be devoid of any visible colour tint. I remember using Skylight 1B (IIRC) back in the film days, and as well as UV cut they did also have a very slight pinkish tint, I can't find my old Cokin filter to check at the moment though. I know that with colour film they did have a positive effect, especially used in areas where there were higher levels of diffused UV about, such as at the beach, or in the mountains. I know that modern digital sensors have both Ir and UV cut filters built into the sensor stack, but I suppose that you can still use modern lenses with older film bodies, so using UV/Skylight may be beneficial for some at times.
