The Tiffen 55mm UV 17 Filter is 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. Canon EF-S 17-55mm f/2.8 IS USM Lens Is this lens compatible with the Cannon rebel T5 and T6?

A: It should be. I agree with Charles B. Surly not an expert, but it would be a good start if you do upgrade. F/2.8 is always good to have for indoor shots.

Q: 2. I'm interested in the new Canon 7D Mark II. Would this lens be compatible with that camera?

A: Yes, this lens is fully compatible with the 7D Mk II camera.

Q: 3. I am traveling on vacation to Europe. How does this lens differ from the Canon 24-105 L 4D lens that comes with the Canon 5d Mark 2 camera? What are the pros and cons? I already have that lens.

A: The 17-55mm 2.8 lens will be specifically for a crop sensor camera. It will have an equivalent focal length of about 24-85mm on APS-C crop sensor. You would not be able to use the 17-55mm on your 5D3, due to the smaller image circle. The closest equivalent for full frame would be the 24-70mm 2.8 L:Canon EF 24-70mm f/2.8L II USM LensB&H # CA247028LII Mfr # 5175B002I would stick to the 24-105mm, unless you need a faster aperture.

Q: 4. Is this lens compatible with Canon 40D and or 6D? I currently have a 40D and thinking of upgrading to 6D soon. Thanks

A: This lens will work well on the 40D, but will vignette on the 6D. This is due to the smaller APS-C-specific image circle found on the lens. If you are going to be upgrading to a full frame camera, an EF lens would be necessary (as opposed to an EF-S, which will not work):Canon EF 24-105mm f/4L IS USM LensB&H # CA241054LIS ? Mfr # 0344B002This is a compatible lens in roughly the same focal and price range.

Q: 5. Is there a matching like 70-200 equivalent that canon makes for EF-S that would pair nicely to this 17-55?

A: I have the Canon 17-55 f2.8 lens. I love it!! I use the Canon 55-250 STM lens and think that it would be best as a companion lens. The 70-200 EF is the APS-C equivalent of 112-320mm. Quite a gap between 55mm and 112mm. I also use the APS-C 10-18mm STM and that way cover from 10mm to 250mm. The quality of the STM lenses is pretty darned good.

Q: 6. Is the lens compatible with 80D camara?

A: Yes, the Canon EF-S 17-55mm f/2.8 IS USM Lens is fully compatible for use with the Canon EOS 80D DSLR camera.

Q: 7. Is this lens compatible with the eos c100 videocamera?

A: Yes it is. The C100 is compatible with EF, EF-S and EF Cinema lenses.

Q: 8. Does this lens have manual aperture control

A: Although the lens has the diaphragm that physically creates the aperture, the camera body is where I set aperture for this lens. My Canon body does have an aperture priority mode that allows me to select the aperture I desire. This lens will shoot with the aperture I set using the Canon body. Not sure if I understood the question, but hopefully this helps.

Q: 9. Will this lens perform perfectly when addapted to R7? Or will there be issues with AF and FPS?

Q: 10. I own a C100 and i am considering the 17-55 2.8 for hand held video - I also own a 24-70 2.8 that i use for photography (brilliant lens for stills) but, i have read the 17-55 2.8 has better image quality then the 24-70 2.8 because the 17-55 2.8 was built for crop sensor - has anyone experienced this? Thanks.

A: I am very happy with this lens for stills and video an my 70 D. Couldn't ask for any more sharpness than it provides.
