How to attach Rocketfish UV filter to canon rebel t2i?
the uv filter I bought at Best Buy says it is for 67mm or 62mm. My camera indicates 67 mm yet it doesn't seem to want to attach. Any ideas?

the two sizes are threaded together. You have to unscrew the 62 to use the 67. I had the same issue

answer 2
your 67mm filter has a 62mm stepdown ring attached. It needs to be unscrewed so your 67mm filter will fit your camera.

The unit comes with an adapter for use with a 62mm lens. That, you don't need when using it on the 67mm lens but it's included so the filter can be used on two different lenses. You can always use it for a child's bracelet if you'd like.
Always back off before threading the filter to the lens. That is, turn the filter counterclockwise until you feel the threads set, then turn clockwise until the filter's firmly attached. It's an old plumber's trick (that I learned from an old plumber) and will keep you from cross threading and ruining the threads on the filter, and more importantly, the lens itself. Remember, don't thread the filter on too tight,,, you'll want to remove it at some time to use a different type of filter,,, just make sure it's 'tight enough'.

I think strength is a little misleading when referring to an Ultraviolet (UV) filter for camera lenses. UV filters should allow all visible light to pass through the filter, and only filter out light on the Ultraviolet range of the light spectrum. In the past there were certain films that were sensitive to some parts of the UV spectrum, but digital camera sensors are not sensitive to UV rays.
It is true that there are two different classifications of UV filters called L37 or L39. L37 filters remove all UV rays in the range of 370nm and shorter, while the L39 filters remove all UV rays shorter than 390nm. Since digital camera sensors are not sensitive to UV rays either type of UV filter will have the same exact effect on the image captured, which is none at all.
In fact the only benefit to having a UV filter attached to the front of a digital camera lens is to protect the front lens element, which is a very important thing to do. In all my years none of my SLR/DSLR lenses have ever been without a UV filter attached to the front of each lens. To be honest I don't know if this Rocketfish lens is a L37 or L39 UV filter, but if it is going to be attached to the front of a digital camera lens it makes no difference.
Hope this helps!
