You spent a lot of money for your SLR or digital SLR camera, and then you plunked down another large chunk of cash for a quality lens.  Do you really want to blow another heavy chunk of change for a basic, thread on UV filter?  Well, I would normally advise that you don't skimp on quality when it comes to filters.  After all, would you pay a premium price for a high performance automobile, only to fill it with watered down fuel?  I should nope not!  So is it such a bright idea to buy such a low cost UV filter for your high-end SLR lens?  Well, maybe it is if you are considering the Tiffen 77mm UV Protection Filter.

This filter does NOT offer the highest level of UV filtration, but it is rather sufficient for most conditions, and the build quality and materials used in this filter are very good.  For most digital SLR users, a UV filter is a must have for protecting your lens optics, and it helps to clear up the hazy and washed out look in many of your outdoor photos.  This filter has proven to clean up many of my digital photographs, and I have found almost no internal reflection artifacts.  Notice I said ALMOST no internal reflection.  I leave my UV filters on all of my lenses almost all of the time, and this filter has produced some minor reflection when shooting indoor photos with my Sigma 10-20mm ultra-wide angle lens.  This seems to only happen when shooting in dim lighting conditions, and when aiming the lens in the direction of a strong light source, such as a table lamp.  Since my Canon EOS 40D has a "Live View" feature that lets me see what the picture is going to look like (displayed on the 3" LCD), I can see the reflection artifacts before I shoot the picture, and therefore have found ways to reframe my shots to avoid the reflections.  However, I recommend that you simply remove the UV filter when shooting in these conditions.

As I said before, I typically do not recommend buying low cost filters for your high quality lenses, but I prefer to invest my money on creative filters and not pour too much into a filter that is primarily used to simply protect the front of the lens.  Many manufacturers, including Tiffen, offer higher quality UV/Haze filters for SLR lenses, and you may wish to spend the extra money if you are looking for deeper UV removal from your pictures.  However, if you are looking for great lens protection and a decent level of UV filtration for a modest investment, you honestly can't go wrong with this filter.  Just remember to remove the filter, or frame your shots carefully when shooting in situations where direct light reflection may be an issue.
