@Kirill It’s not possible. The AF in the TC-16a is “screwdriver driven” and requires the Camera body to have an AF Motor, which the D3100 does not, only cameras from the D7000 line (D90, D80…) and up have that.

Hi all,

I did the pin switch and used the copper tape method to redirect signal from new pin 6 to the old pin 3. Not only did I not get any AF action but the lens reports as a manual lens on my d300, no chip detected.

Before ‘mod’ I did briefly mount this TC on a Nikon N2002 to test whether it worked, it did not. Subsequent research suggested an unmodified tc 16a would not be compatible with this camera. Did I brick the electronics? Since I never tested it with an older camera before modifying I’ll never know!

Any suggestions besides putting the pin back, finding a ‘control camera’ & testing it in ‘original’ condition would be appreciated..

Thanks,

DDK

Thank you very much Oliver…! (please..be patiente with my bad english.. :)
I have a Nikon D90. I made the pin changes like you teach us, and have an excellent result, all right with the auto focus.. great.!! I didn´t cut P11-2 and P11-3 and for that the max F1 is there. Could I use the ring of lens without guess change the CPU of Tc-16A. I read all your specification about changes on the camera controls on the D200 and later. I use all MF Nikon 105mm F2.8, 135mm F2.8 and 180mm F2.8 and I want to use the lens ring for change the aperture diafragma. With the TC-16A mod I have the fine last autofocus but the manual ring for control the aperture don’t result, the aperture is fix on the max, the same case with the three different Nikon lens F2.8.
What can I do for use the TC-16A autofocus and at the same time have control aperture with use of the lens ring..?
Thank you again, for this excellent and generous publication.
Kinds regards
Roberto

Hello, great site, thank you for sharing your knowledge! Has anybody already tried to REMOVE THE GLASS from the TC-16A to use it as AF-macro-tube for MF-lenses? Or is this impossible? Perhaps the diameter would be to small, or removing the glass would cause damages … (?)

@Alan, if you read through the comments, you’ll see further modification described, which would explain the f/4 display.

It sounds like you’re trying to focus on something outside of the focussing range, so it will hunt back and forth once and give up. (as any other lens would too). Also, forget using it in the dark, especially combined with the 500mm f/8 Autofocus will only work in bright sunlight.

You need to pre-focus your lens manually, and then (half)-press the shutter, for the TC to be able to auto-focus. It’s range is quite limited.
