Nikon 20mm f/1.8 AFS G Nikkor: Chromatic Aberration

After yesterday’s post, I got some requests about how well the new Nikon 20mm f/1.8 AFS G Nikkor lens handles chromatic aberration (CA). For the record, when I test a lens, I try not to obsess about lab benchmarks and instead focus on just using the lens. I haven’t been able to go out to use this new lens in a real situation yet, but so far I’ve seen nothing to suggest that this lens isn’t an excellent addition to the Nikkor line.

So, a quick CA test for all the pixel-peepers after the jump. Continue reading Nikon 20mm f/1.8 AFS G Nikkor: Chromatic Aberration

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
