Testing my Nikon 45mm Perspective control lens with the new Nikon D850 bodies. Testing out lens diffraction correction in Capture One 11. Basically, if you shoot at a small aperture (here at f/13) - you will start to lose sharpness. Capture One has several tools to help you "recapture" sharpness loss from diffraction. Testing this on the D850 Nikon, a 46 megapixel monster - the perfect combo. I've tested the new Nikon 19mm perspective-control lens and it is stellar. The Nikon 45 and 85mm PC lenses are an older design.
I am looking for the sweet spot from each lens. Shooting a lot more infrastructure projects these days and the PC lenses are the perfect tool to use for this type of "architectural" photography.
I often use Wilson Bridge in Alexandria as my lens test subject.
