Which UV Filter? I'm a new owner of a Nikon D70 with an 18-70mm lens. It seams like Nikon is not providing a UV filter for this lens (for 67mm filters) to protect it! Any suggestions? What filter is recommended for this lens? Thank you for your input!

Hi Thomas. 67mm is a standard filter size. Your local photo outlet should be able to help. There are many arguments about using a filter as a protective element, as adding any extra glass in the light path will always lead to image degradation and possible flare. Many (most?) professionals would not be seen dead with an unnecessary extra layer of glass in the light path. If you do want to use a filter, don't skimp on it; spend some money ... $50 should get you a good UV filter. Cheers, DC

I agree with Dave ... although I do keep UV filters on most of the primes in daylight outdoors to cut down the UV that shows slightly with some of the films I use. Primes have much less glass than zoom lenses; more UV makes it through them to the film. I remove the UVs under various conditions that could create visible reflections from the two additional air-glass interfaces ... tacking a filter onto the front adds to the optical system (a.k.a. flare). IMVHO, a good lens hood does more to protect the front of a lens from many hazards, and it provides at least some additional flare control from off-axis light sources (how well depends on hood design). Anything that gets past a lens hood is also very likely to punch through a filter into the lens. The two best filter makers are B+W and Heliopan. Hoya is also good, but at the next tier down from them. Tiffen's advertising hype is mostly about their cinematography filters, and their reputation for them, which are definitely NOT the same as the inexpensive ones they make for still photography. For anyone like me who has lenses with metal barrels and filter threads, Tiffen's aluminum rings also "gall" in the threads, making them nearly impossible to remove (B+W's and Heliopan's are brass, which does not gall). A good filter has the dye in the otherwise optically clear glass, not a sandwich of cheap glass around a gelatin film. The two surfaces will be absolutely dead flat and parallel to each other. The best filters have these characteristics that minimize their effect on the optical system.

Thanks for the info! I probably will take a look at the B+W filters. Also, I'm not always using the filter. But I like to have it on when I travel. I also use the hood to protect the lens.
