I recently converted my Nikon 1 V1 mirrorless camera to “super-color” infrared. I’ve been having fun with the camera, but I did notice that wider shots seemed very soft in the corners. According to the team at Life Pixel, wide-angle lenses are notoriously problematic with infrared cameras. Lens distortions tend to be exaggerated and softness is common. The primary culprit, it seems, is the fancy optical coatings on your lenses, which help reduce distortion and aberrations. The coatings are optimized for visible light, not IR wavelengths.
As much as I hate taking pictures of brick walls, I also want to understand the limitations of my gear. I decided to test three of my 1-Nikkor lenses to see how well they performed with infrared. Continue reading Infrared Photography with the Nikon 1 System: Wide-angle lens testing
