"I'm usng a Canon EFS 18-55mm IS and a 75-300. It happens on either one. I mainly use the UV filter for lens protection but if that's contributing I won't use it"
Most people don't have a clue about filter use. Some reside here on this forum. The facts are, cheap filters are"cheap". Just like a cheap lens isn't as good as the most expensive lens. No different than anything you buy. You get what you pay for, type thing. The truth is, filters of any kind are mostly a thing of the past. They have been made obsolete by the advent of the DSLR.
However, a couple filters remain as still somewhat important or necessary. These could be an ND, a polarizer and the protecto filters. The first two depends somewhat on you ability in post editing with software like Photoshop. Now for the protecto filter.
It probably doesn't make a lot of sense to buy a protecto filter that costs half or so of what the lens cost. But filters have a feature that almost everybody forgets and certainly overlooked here on this forum, they come off as easily as they go on! When you need it, use it. When you don't remove it. Simple? Now for the last feature. You can actually use the expensive protecto filter on more than one lens! If it fits, of course.
It is always best to keep your gear all in the same quality level. If I were you I would look for protecto filters that more or less do that all will be better. Most of the time they will be out of sight out of mind. But sometimes they may cause problems. That is when you remove it.
Now you have the straight skinny on filters.
