Older Nikon lens on my D7100 (Page 2): I also have a D7100 and use it with old Nikon (not so old they would do damage) and t-mount lenses. Just a hint

I also have a D7100 and use it with old Nikon (not so old they would do damage) and t-mount lenses. Just a hint - you can shoot in aperture priority and not have to meter. I have one problem with my 58mm - it fits so tight that I have to take the lens off to set the aperture. - Dave

If it fits that tight it's probably a pre-ais lens.

therwol: A BIG, BIG thank you for the warning. I now need to learn how my lens could be modified, if that is at all possible. The lens, as well as a 150mm telephoto and 35mm all are non-AI, having the "saddle" that engages the aperture sensing pin on the meter head. My D7100 thanks you, too.

If you do get your pre-AI aperture ring modified and use it on your camera, there is one more step you need to take. You need to enter the focal length and maximum aperture into your camera as a non-CPU lens. I believe that after this is done, you can use aperture priority metering or manual metering, and the exposure data will be entered properly into the EXIF data on your pictures. I think that you control the aperture with the aperture ring rather than the camera. These images are from your user manual, pages 149-151.

Especially at 58mm .... was there
ever an Ai version of 58mm ?

Thanks. I had already read that, both in the Nikon manual and Thomas' Digital Field Guide. Your information has prevented a nasty surprise had I tried to use the unaltered lens on may 7100. THANK YOU!!

I know of at least 4 Nikon 58mm lenses. Do you have the oldest one sold between 1959 and 1962? Every version after that is AIs, or G or designed for the new Z cameras. If you have the original, it sells used for $300-400. (A cursory look on the web.)

Really. Are you sure you're not wedging the lens against the aperture ring feeler, causing it to become difficult to move and risking camera damage?

All - The aperture ring on my old 58mm lens was stiff from none use making it hard to set on the camera.
After working the stiffness out it works both on and off the camera. - Dave

Do you have the 58mm f/1.2 AIs? Super lens if you do.

Nikon has several different mounts and you need to verify if there is damage. Pre AI lenses as stated can damage some post AI cameras unless they have the feeler that flips up or the mount is changed to accommodate AI cameras.

Just avoid Pre-AI lenses.

It's a simple modification, however the location of the ground in relief is critical for the camera to accurately detect the lens opening for the meter. I am a professional handyman with over 30 years experience, yet I would not do it myself. Unless you are extremely careful and steady with your hands and have proper tools ,you will likely ruin the lens/ lens value e.i. the example posted above. It should be a $25 - 40 job to have it done properly.
