The 37mm Kolari Vision UV Bandpass Lens Filter 37mmfrom Kolari Vision UV Bandpass Lens Filter 37mmis designed to work with a full-spectrum modified camera for true UV photography, skin damage analysis, forensic analysis, astrophotography, and other uses. Unlike many third-party UV filters that use interference coating, this one features absorption-based glass, doing away with the problem of inconsistent color across the frame.

The filter has a 50% transmission peak at 365nm, and >25% transmission in the 340-380nm range for high transmission. Average out of band rejection is >OD 4.3 (0.005%), with a minimum rejection of>3.5 OD (0.025%), so there is a high signal to noise ratio and no IR contamination. The filter is coated for durability. Due to the thickness of the glass, the filter is threaded on the rear side only.

This filter requires a full spectrum modification to be made to your camera in order to function properly. This entails manually removing the camera's low-pass filter and replacing it with a clear filter. Once that's done, the filter will work as intended. (Kolari Vision can make the modification for you at a cost if you send in your camera to them.)

Q: 6. Does barrel distortion increase when shooting with nikon Z8 in DX mode?

A: The barrel distortion does not increase when shooting in DX mode. Due to the crop, it actually should be less noticable. If you're shooting RAW, the distortion is easily corrected by softwares like Adobe Lightroom, or Capture One. Alternatively if you are shooting JPEG, you can go into the Z8's Photo Shooting Menu. You will find "Auto distortion control", if you enable this function you will eliminate the distortion in both DX & FX modes.
