However, if your lens only transmits the longest UV wavelengths your photos will feature a monochromatic violet colour regardless of the subject. How do you focus a Fujinon 23mm 1.4 in the dark?

The basic idea is that, if you drop your $2,000 lens, instead of breaking the front element of the lens, you break your $35 UV filter instead. To unlock sensitivity to those shorter wavelengths, a camera has to be physically modified to allow passage of light below 400nm.

What is a UV Filter and Do You Need it to Protect Your Camera Lens? When photographing outdoors UV light manifests itself in the form of haze, which can vary based on how close you are to large bodies of water or snow (water and snow both reflect sunlight, which in turn magnifies UV levels), altitude (the higher you go, the more UV light you encounter), and larger cities (reflective glass and metal-clad structures can also amplify ambient UV levels). After conversion your camera will have much higher UV sensitivity and you will no longer need any UV filters in front of the lens making it easier to compose and focus UV photographs.

The email address you entered was an invalid email. While producing some different coloration, the 720nm and B+W 403 both prominently display this property.

The flat peak of the NIR-Block is interesting. I learned a lot from this article. Gelatin filters are available in rolls for gelling lighting fixtures and windows as well as smaller square and rectangular shapes for use in screw-in filter holders from Cokin and other manufacturers. Most types of lenses allow longwave UV wavelengths to pass but absorb all the other UV wavelengths (350 nm and below). Conveniently, they also allow infrared light to pass through which the camera can't see either, so they can serve multiple purposes. If used gear is found to be damaged, defective or not as described, it must be reported within 14 days of purchase for potential return. We then have to filter out visible and infrared light or else any UV light coming through the lens will be drowned out by the much more plentiful Visible and IR light, and the ultraviolet signal we are looking for will be lost.

In that case, its a lot easier and safer to clean a UV filter than the glass of the lens itself. (verified owner) August 2, 2019. Although I'm of the tradition of "correct optically over digitally", sometimes complex optical corrections aren't practical (sunset over a wind-swept body of water, for example - how many filters can be combined before the image is useless due to crazy optical anomalies and severe vignetting). Though the lotion does glisten brightly from certain angles, our filter is the only one showing UV absorption while the B+W 403 is once again performing more like an infrared filter.
