Capture One lens diffraction test

CD_2018_0219_0019.jpg

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.
