    All of my lenses have UV filters on them. I was wanting to try a circular polarizer. Do I lose anything by just screwing it into the UV filter or is it better to take the UV filter off?

    You'll always lose a little bit by adding more glass/plastic in front of a lens...but it may not be enough to really notice if everything is of sufficient quality.

    If your lens is a wide-angle model, though, you may experience vignetting from the extra filter bezel.

    Something else to consider...going without the UV filter. I was from the old school that believed in protecting the lens front element with a UV filter. Now, I'm of the mindset that if I've spent princely sums on great glass, why obscure it with more (cheaper) glass? Front elements today are much more durable than when I first started out...and tiny blems don't seem to degrade image quality significantly.

    You pays your money and you takes yer chances.

    I had always used a UV filter just for protection until one day it had a spot on it so I shot without it. I was very pleased with the result of my images (esp. the popping of the colors) and had left the filter off ever since!

    Stacking filters isn't a very good idea. While you can produce ghosting with a UV filter, it is virtually impossible to produce flare. It is, however, possible to produce flare with a stack of filters. Flare will reduce contrast in your images. Use them one at a time and you'll be fine.

    I don't leave a UV filter on my lenses because I use the lens caps anytime they're not in use. (This includes when I turn the camera off.)

    But it is when they are in use that they need the protection, not when they are not in use!
