Fine blowing sand at beach or desert is enough proof for me. Takes one missed grain on the glass and when you go to
clean with your lens cloth, there is nothing sharper to create those fine scratches on your glass.
Like I said, if you don't shoot in conditions that warrant a protective filter, then using one is a waste of time. However I pointed out senarios that are real where a protective filter will reduce your chance of damaging your front element. And no, the lens hood will not help much in these conditions.
1 grain of sand - really?
I spend a minimum of two weeks a year in Mexico. Have taken the same camera and 4 lenses down there every year for the past 6 years. Have never used a UV filter for any reason on any lens. And while I think I'm quite protective of my gear - people on this forum would have you believe I abuse it and shouldn't be allowed to own it:
1) Of my 4 lenses, 3 are primes and I change them CONSTANTLY ... on the beach. I take no special measures to protect the lens or the body when changing out glass other than simply holding the body face down so that gravity helps out a bit.
2) I routinely get myself in the pool with my body and lens (often my one zoom, my 70-200 2.8) and enjoy the perspective of being 4 inches off the water. This frequently results in water/spray on my gear and the end of my lens.
3) I prefer to take the good gear on the adventures cause those are the shots I really want to get right (as opposed to taking a water-proof P&S):
4) And I LOVE shooting in the rain for the colors and the effects. Now in this shot, of course I had filters in place - you don't get a 6-minute exposure in daytime without some serious ND stacking - but nothing need to be cleaned after this shot and keep in mind that while you can't see it because of the shutter time, this shot is dead smack in the middle of a severe rainstorm:
Seriously - listen to others. The UV filter as protection thing is myth. They don't do anything but degrade image quality and break really easily. Have you ever actually seen the thickness of the front element on any of your lenses? It's easily 5 times thicker than a UV filter and it happens to be convex which adds plenty of strength from front-impacts.
Stop wasting money and ditch them things forever. If you're really worried about wiping sand on your front element and scratching the glass, get a Rocket Blower and a Lens Pen and be done with it. Those are the only two "cleaning" items that exist in my bag and in 20 years of shooting I've yet to come across a situation that either of them couldn't handle except for the following parting story:
The first vacation my wife and I ever went on as a couple was to Mexico. I was still shooting film back then via a Canon SLR, we took a dune-buggy adventure tour in Puerto Vallarta and got COVERED head to toe in mud - including my camera and the lens. Next time I stopped the car I put some water in my mouth, spit it onto the front element to wash away the excess mud/dirt, cleaned the water off with part of my underwear (only part of me not covered in mud), and went on shooting. Still have those prints in an album on my bookshelf. Washed the camera off with a damp cloth when we got back to the hotel and forgot the event ever happened. Did nothing to any of my gear and none of it was weather sealed.
