We also offer it as a drop filter to fit the Canon drop in system, allowing you to use any EF lens with the filter. Some photographers swear theyre essential, while others are equally certain theyre a total waste of money. In the comparison below, the picture on the left was taken with a IR 850nm filter. Ultraviolet photography is an interesting photographic method of capturing images by using light from the ultraviolet spectrum. There are also interference filters they use dielectric coatings on a substrate of fused silica that transmits UV. https://www.bhphotovideo.com/explora/photography/tips-and-solutions/when-not-use-uv-filter , 2000-2023 B & H Foto & Electronics Corp. 420 9th Ave, New York, NY 10001.

But plain glass alone cannot dampen the effects of UV radiation as thoroughly as glass with coatings designed to further block UV light. However, I noticed there's a problem -- these filters completely obscure visible light, making the viewfinder and liveview useless. Bandpass filters are passive optical devices that control the flow of light. adroll_adv_id = "QEE5KAS6EVDYBBXDKMO7VQ"; Weve tested this filter against our own hot mirror filter, and show that it lets in much more IR light, and produces worse color accuracy when used on a full spectrum camera. : Elec.
