A UV filter is also useful as a general protective filter to leave on a lens at all times. This filter helps to reduce dust and moisture from reaching your front lens element and provides additional protection in case of drops or situations where scratching could occur.

This Sigma WR UV Filter is coated to repel water drops and resist smudging from fingerprints. It is also treated to exhibit antistatic properties to prevent microscopic dust from clinging to the front surface. This helps to ensure sharp images.

Q: 6. Has anyone used one of these on a Sony A7s series camera? Both versions of the A7s come with a Low Pass filter, which I believe cuts down much of what this filter is intended to do, so is it irrelevant?

A: I haven't used it on a Sony and don't know their specs, but generally Low Pass filters don't cut UV, and don't cut all Infra Red. You can test by taking a photo of the IR cell on a TV remote while pressing one of its buttons, if the photo shows a light in the cell, IR is getting through. I normally use this lens for work where extreme sharpness or clarity is critical or when using tungsten lighting.

Q: 7. would this filter fit on the Sonnar T* FE 55mm F1.8 ZA Full-frame E-mount Prime Lens?

A: The Zeiss 55mm UV filter will not fit the Sonnar T* FE 55mm F1.8 ZA, as this lens has a 49mm filter thread. You will instead want a UV filter such as the Hoya 49mm UV Haze NXT HMC Filter: http://bhpho.to/19tNmPU
