[QUOTE="Brian, post: 216033, member: 17621"] Why not just dump Nikon altogether and switch to Canon? With Nikon- you are stuck with a 55 year old mount and meter coupling designed for a clip on Selenium Cell Meter. Everything that followed has been a hack, kludge, and compromise to retain compatibility with lenses that were obsolete when AF was introduced almost 30 years ago. The throat of the F-Mount is too narrow to produce an Autofocus 58/1.2 lens, so Nikon engineers went with an f1.4 instead- for over $1,600. About double what the 58/1.2 Noct-Nikkor sold for when it was in production. Canon figured out how to make a 50/0.95 RF coupled lens- they cut the top off the glass to place the RF coupling , knowing the frame was 24x36- Over 50 years ago. Looking at the back of the Nikkor 55/1.2, some glass could go to make room for the electrodes for an AF lens. Canon made a 50/1 AF lens for their AF mount, they dumped the manual-focus FD lens decades ago. All you gave up was using that legacy glass. [/QUOTE]
