Of course, it will also work with most lenses with 58mm filter threads. (Front glass element must not protrude beyond the filter threads)

The ARTCISE Ultra series UV lens filter is one of my personal favorites and boasts the following features:

1) Uses German Schott B270 HD optical glass.

2) Double sided with 36-layers nano-scale multi-coatings. All these coatings provide several benefits:
- Extremely well controlled lens flare (see last photo for my lens flare test comparison)

- Hydrophobic property to repel water

- Anti-scratch property to resist scratching

- Anti-static property so as to not attract dust

- Oil-proof property

3) Super slim 3.37mm thick frame made of aviation grade aluminum alloy reduces almost any vignette effect.

4) 99.8% utlra-high optical transmittance and 0.1% ultra-low reflectivity

5) UV cut-off wavelength 370nm and below

I personally use these UV filters for all my expensive lenses as protection for the front glass element. The flare control is better than any other brand I've tested, from very expensive German brands to the cheapest ones.
