A reader recommended the Schneider F-mount 60 and 80 mm lenses that are specified for 400 nm to 1000 nm light, and offer a 60 mm image circle, which would cover the GFX sensor with 5 mm to spare. The 60 mm lens runs about $1300 at B&H. I’m not in the market for it,… [Read More]

Test protocol: Manual exposure, the same for all images 12 meters target distance ISO… [Read More]

The Schneider 90/4.5 Apo-Componon HM is an enlarging lens that I happen to have lying around from my film days. I remembered it as a great enlarging lens. I wondered how it would perform in a completely different role: as a camera lens. This is asking the lens to perform well outside of its comfort… [Read More]
