This Canon lens works well for UV photography to about 340nm. With its simple construction, it passes UV much better than a complex prime or zoom lens.
The lens uses 52mm filters. If needed, you can use a 52mm to 58mm step-up ring to mount 58mm filters to the lens. We have the greatest selection of filter options in 58mm diameter.
