I upgraded from an infrared-converted Nikon D7200/720nm to a Nikon D750/550nm combination this past spring. Although I suspected the D750/550nm filter would suffice for most of my infrared needs, I was hesitant to forego the bright whites produced by the 720nm filter. As such, I decided to test two of Kolari Vision’s external filters to determine how well they would perform on my D750/550nm configuration.
