Non-AI Primes to Autofocus Zoom
Aug 2, 2019 15:27:45 #
I currently have 4 Non-AI Prime lenses synced to my D750. I borrowed an Autofocus Zoom for an upcoming trip to minimize having to constantly change lenses. Do I have to wipe out the Non-AI settings on my camera before I can use the Autofocus lens or can I set an unused Non-AI setting, let's say 'No. 5' with no parameters and use that when the Autofocus lens is attached? I have only used the Non-AI primes with this camera so I am unsure. Thanks for your reply!

Attaching an AF zoom is all it takes. I have 9 old lenses set up on my D 750 - I need to choose the correct number for each of the old lenses, the camera "recognizes" modern lenses. You will have to change the switch from M to AF. Good shooting!

I hope those old lenses are Ai or AiS and not Non Ai as the Non Ai can damage the aperture follower tab on the D750...

They are likely NOT non-AI, but AI or AI-s because a non-AI (aperture index) lens will cause damage to the aperture feeler tab in your D750 (and any other body). As for using AF or AFS lenses, it’s automatic when the lens is mounted - if you have not touched the M/C/S switch or M/AF switch on the left side of the lens mount.

Actually the DF was designed with a tab that folds out of the way. It can be used with nearly all F mount lenses.

The base model Nikon DSLR’s also have no aperture feeler tab either, this those older Non-Ai can be used on them as well. I used to moderate a forum over on Flickr dedicated to the use of those older non metering lenses on Nikon DSLRs and lots of people would post images taken with those older lenses on their base cameras. You had to manually meter the scene though thus they were not suitable for fast action or situations with rapidly changing light. Nikon said the lenses wouldn’t work on base model cameras but they did.

The DF does not have the proper pin to properly operate with Non-AI lenses. They will mount and that is it.

They mount and operate manually.

So were a number of other Nikons. But the OP has a D750, not a Df. Does it have a folding meter-linkage tab? And, you still have to fold it by hand.

The Df while doesn't have the coupling pin for Pre AI lenses it can meter the Pre AI lenses in manual and aperture priority mode. What you have to do is first to set the lens maximum aperture (just like the AI lens but choose Non AI in the setting). When you set the lens to any aperture you also set the aperture readout in the viewfinder to same value using the Sub Command dial.
For metering in manual mode, you can turn the Sub Command dial to meter the scene. After that you set the lens aperture ring to the same value.
For A mode, set the aperture ring to the value you want to use and then set the aperture display in the viewfinder to same value using the Sub Command dial. The shutter will automatically adjust based on the scene brightness.
So PreAI lenses do work in A and M mode with the meter functional.

Just making sure from the first comment that people are not misled as frequently is done with Nikon defenders.

Providing incomplete or incorrect information is not an effective method of making sure of anything. Sorry.
