Any change of actually seeing pictures here?
UV-filters, well, use 'em if you're scared or there's small rocks flying around like in a rally and don't mind a ruined photo every now and then when the filter shits itself due to some stray light.
The pros treat their kit like crap because they are pros and have stuff to do, pictures to make and have little or no money tied to their kits. Simple.
And if you ding the front element, it takes a huge crack to have any real life effect on the image. And if it does, send it for a front element replacement.
PICTURES NAO!
