Using an F100 with older manual focus Nikkor lenses

[andylynn]

<p>G lenses don't use the AI tab. That's lenses that don't have an aperture ring - these will work as normal on your camera.</p>

<p>If you can find somebody to do the repair I don't think it should be too expensive. If they can get the part, it's a simple one, so you'd be looking at the minimum time they'll bill plus a few dollars for the part.</p>

<p>Right you are Andy L. 'G' lenses, and only G lenses, can meter without the AI tab. Wasn't thinking it all the way through there obviously. But any lens fitted with an aperture ring is going to be severely restricted.</p>

<p>It is worthwhile getting a repair estimate. The cost will mostly be the labour involved, as the replacement assembly is a simple piece of plastic with a spring (p/n 1B610-059)</p><div></div>

<p>Nikon calls it a "coupling unit" in the parts list for the F100 ...</p><div></div>

You guys have been wonderfully helpful. I will get this fixed. I had heard great things about the photo.net community,

and you guys delivered.

 

Thank you.

<p> I looked at my F6 and FM2n and I see no AI indexing tab. I know they work with AIS lenses as I have used them on them. They are the ones with the orange high F stop numbers in two rows. I don't own any AI lenses unless the Nikon mirror lenses are considered that.</p>

<p> Never mind my last post. I must be half blind. I see the indexing tab now on these cameras. It is not as large or pronounced as I was expecting. I put an AIS lens on them and they hit the tab and rotate it.</p>

<p> I looked at the tab on Chris's F 100 in the picture and it doesn't look shorter than mine or broken. Perhaps, that is not the problem.</p>

<p>Look again. Closer. ;) :)</p>

<p>The tab should be visible on the <strong>outer circumference</strong> of the indexing ring at 1 o'clock. See Shun's photo posted Sep 11, 2011; 06:35 p.m. Now compare that to Chris's photo posted Sep 11, 2011; 06:10 p.m. It's clearly missing and not there. Broken off. End of story. Mystery (and problem) solved.</p>

<p>I hope this image helps. I bounced the flash from the left side so that hopefully the follower tab stands out more.</p><div></div>

<p>Thanks so much again. Yes, sad to say, the tab is missing on my F100.<br>

It has already arrived at KEH for repair. The estimate was $120. They are examining the camera now and I await a call confirming the diagnosis.</p>
