I got my first camera in 25 years due to my older Canon taking a fall from its tripod. I went with a new the Nikon Z30 and saw a decent used Quantaray 200 to 55mm telephoto/macro lens that has a Nikon F mount for $10 on eBay. Now, I know why. There is no manual way to control the aperture. A brief search did not return anything helpful for DIY digital control or the protocol.
There are 5 electrical contacts at the lens base arranged as a group of 4 +1. Has anyone sorted out the protocol for that control? I would simply set the aperture to something useful and control focus and ISO manually.
Failing that, will the electronic FTZ (Nikon F to Z with electrical contacts) work with it? It does fit a non-electronic FTZ adapter.
Regards, John
EDIT: just found this:
The basic Nikon F interface is 5 pins, Vcc (regulated power), RW1 (tach), SCK (serial clock), SIO (serial data), gap, gap, LGND (ground).
I2C? My Nikon Z has more pins than that.
Apparently, drive is a screw/motor drive.
