Kolari Vision KV-FL1 Overview

The KV-FL1 Multispectral Flash from Kolari Vision is for illuminating your subjects in indoor IR/UV applications, when you use IR or UV filters with a full-spectrum modified camera. The flash unit comes with IR (850nm) and UV flash filters, also referred to as flash cups, which attach to the flash head. When you use the IR flash cup for IR applications, it will make the flash only barely visible to the human eye even on the highest power settings. The UV flash cup reduces the flash to a softer, purple glow.

This speedlight style flash features a standard hot shoe for use on- or off-camera. Clamp-mount focus assist flashlights are included to help with focusing and composing your shot. These flashlights will light your scene in the spectrum that you need, allowing you to see what you're going to get before the flash goes off. This lets you eliminate trial and error. The flashlights attach to the flash via quick release clamp-mounts, allowing for quick and easy swaps for IR and UV applications.

The flash unit runs on four AA batteries. The focus assist flashlights are each powered by a single AA battery. Only two AA batteries are included (one for each flashlight).

Kolari Vision KV-FL1 Reviews

I like it, but its real basic for the price

By Andres
Rated 4 out of 5
Date: 2023-02-09

Have used it with the UV filter, have not yet tried the IR filter for it. It has to be used on the camera hot shoe or triggered manually during a long exposure for best results. I didn't get consistent results with infrared transmitters and it does not bring an option of using cables. With the filter on the power is not enough to trigger with a slave. It does what it does but it takes a little too adapt to get it to work the way it should.

Is this compatible with a Fuji X-series camera? Will TTL work? If not which brands is it compatible with?
Asked by: Paul
Yes, the Kolari Vision KV-FL1 Multispectral Flash with IR and UV Flash Filters is compatible with Fuji X-series cameras because the Fuji hot shoe is standard. This flash unit's TTL is not compatible with Fuji. However, TTL is available for Nikon and Canon cameras with the standard shoes only.
