I wanted to create a thread specifically for this in the hope that more people might see it and maybe be able to report similar/identical issues.
I've had my TC-20E III for around 2 years, never had an issue with it, 300mm 2.8 for around a month, never had an issue with it, D750 for around 2 months, never had an issue with it.
Now, a few weeks ago I wanted to use this combo for motorsports, connected all three together and it was fine, all of a sudden it stopped focusing. I tried everything, turning the camera off and on, disconnecting the TC at both the lens and camera end, changing battery, removing grip, absolutely anything that came to mind. When I try and focus, nothing happens within the focal screen on the lens, meanwhile my aperture is going crazy flicking between 2.8 and 5.6, which leads me to think there's some kind of dodgy connection.
I have a D800E with me also, which has always worked perfectly with any combination, I take the TC and lens off, put them on the D800E and it worked perfectly for the 3+ hours I was using it. Now, at the end I wanted to test the D750 again, so I put the combo back on, works fine for about 10 minutes then goes into broken mode again.
I tried to re-enact the issues tonight at home, it seems that every time I put the combo on the D800E, the D750 works fine for a few minutes, however if I turn the D750 off or anything, it goes back into broken mode.
It's absolutely bizarre, and far more than a coincidence as I've tested this so many times now.
I had been following this thread on Flickr: https://www.flickr.com/groups/2682619@N24/discuss/72157647884559639/ - I noticed that it's actually been updated this week, and that the lens was 're-chipped'. But from my understanding the people having problems in this thread don't get the intermittent issues like I do, just that it doesn't seem to work full stop.
Anyone else experiencing anything crazy with the D750 and teleconverters?
