using a PN-11 extension tube
Hello folks. I am just getting into using a couple of MF lenses and have a question about using the PN-11 extension tube. I hope this is the right place to ask....let me know if it\'s not.
In your experience what are the shortest, longest and most used manual focus lenses with this extension tube?
thanks Jim S aka \"wapsijims\"
Hi Jim, welcome.
This tube is a perfect match to the 105mm f/2.8 AIS micro to result in a ~ 1:1 magnification.
Otherwise it is usable with excellent results in virtually all Nikkors, except perhaps with wide angles because the working distance would be ridiculously small.
I do recommend you research what is the native magnification of your lenses here:
and then calculate both magnification and focusing distance in this excellent calculator (middle of the page):
For example, the Nikkor 50mm f/2 AI have a native magnification of 1:6.7 = 0.1493x and a MFD of 45cm.
Applyingthe native magbification of the lens and the PN-11 (52.5mm of extension) to the calculator we get
the new 1.2x of magnification and a 21.17cm of MFD.
Some sample shots and applications:

ISO 400, f/11(5.6) at 1/100s.
and an application with longer teles:

As the MFD of this old non IF lens is 5m, and the bird was at 3.5m, I had to use the PN-11 tube to get focus; ~10% cropped.
