The Tiffen 55mm UV 17 Filter for Camera Lens Protectionis a general use, clear filter that helps to absorb ultraviolet light and reduce the bluish cast of daylight. This filter is especially useful when photographing at high altitudes or around bodies of water. No additional coloration or contrast is provided, allowing you to pair this filter with others. This filter attenuates approximately 97% of UV radiation, slightly less than a UV 2A filter.

The UV filter is also useful as a general protective filter to leave on lenses at all times. Filters help to reduce dust and moisture from reaching your lens element and provide additional protection in case of drops or situations where scratching could occur.

Tiffen filters are made using ColorCore technology; a process that involves laminating the filter substrate between 2 pieces of optical glass, grinding flat to a tolerance of 1/10,000th of an inch, then mounting to precision metal rings.

Q: 1. Water resistant

A: As far as we are aware, this lens has no weather-sealing.

Q: 2. I want to verify that this product is compatible with a Cannon 70D Camera. This is a EP-S lens and they are compatible with a APS-C Sensor (the 70D) but can't find it on a list that is compatible to a Cannon 70D because it is a just released camera.

A: As the Canon EOS 70D DSLR camera has both an EF and EF-S lens mount, the camera accepts all EF and EF-S lenses manufactured by Canon, and would be fully compatible with the Canon EF-S 17-55mm f/2.8 IS USM Zoom Lens.

Q: 3. Is this lens good for high school basketball

A: If it is your only lens, you'll find it too short overall, BUT this focal length pairs nicely with a 70-200mm lens for wider angle images under the basket.

Q: 4. I want to verify that this lens is compatible with my canon 5D Mark III

A: The Canon EF-S 17-55mm f/2.8 lens is only compatible with the APS-C size sensor Canon DSLRs released since 2003. It is not compatible with Canon full frame cameras such as the 5D III. The Canon full frame cameras are only compatible with the EF lenses.

Q: 5. Would this lens work with a Canon EOS Rebel XTi?

A: It works perfectly with XTi - I used to have it and liked much better even than Canon EF 24-105mm f/4 L. In my opinion EF-S 17-55 f/2.8 is the best Canon zoom lens for the cropped bodies. Enjoy!

Q: 6. What would this lens be best used for in photography?

A: Because of the large opening of the lens 2.8, I bought it to use at stage plays that my daughter and grandson appear in. It works perfectly, to ensure the sharpness of the image, I have to jack up the ISO on my 7D Mark II. Great lens.

Q: 10. Will this lens work on a Sony A7sii with a fotodiox adapter? If so, will the image quality suffer because the Canon 17 - 55 is designed for APS-C sensors? I'm more concerned with image quality than auto focusing performance.

A: You would need to shoot in the APS-C/crop size senor mode when using this lens on the a7S II as this lens does not have an image circle large enough to cover a full frame sensor. This will cut down significantly on the resolution of the files you will get from the camera.
