Re: AF fine tune and focus shift for fast lenses
Starting with models released in 2014, Nikon added a compensation feature to AF, which basically works by biasing the fine-tune value according to which aperture the lens will be taking the image at. This requires the camera to have tables of focus-shift values for various lenses. Cameras made prior to that time, have no such compensation and must be fine-tuned using compromised settings.
something i will never forget after last years' struggle with my 400e lens where i was testing afft by stopping down through the range and not re-engaging af after each stop.
