D750 compatibility with 1.4x TC

MarkWebsterMedia

Hello. I'm a pro freelancer and have been generally happy with my D750 bodies, save for one issue: Unlike the D200s they replaced, my Nikon TC14-E II 1.4X TC and Nikon TC20-E II 2X TC no longer provide AF capability with my lenses - namely my Nikon 70-200mm f/2.8 VR1 and Nikon 300mm f/2.8 lens (non-VR). I suspect this may have to do with a focus motor difference between the two bodies...or perhaps electronics differences between my admittedly older glass and newer versions of both the TCs and/or those lenses. Just posting to see if anyone has encountered a similar issue and what my options might be, as I really miss being able to use the TCs - especially the 1.4x on the 70-200, which I've found to be a real difference-maker shooting certain sports and other events. Thanks! Mark

Have you tried contacting Nikon support to see if they have any suggestions. I have not had any issues with the older AF-I TC14E on the D750, but I don't have those lenses.

I think they should work. Here is the compatibility chart. I think your lenses are on there. http://cdn-5.nikon-cdn.com/Assets/Common-Assets/Images/Teleconverter-Compatibility/en_US_Comp_chart.html

i agree with PB_PM, contact Nikon support, i also had TC14-E II issues with my D750, in the end it was something with the lens (300 f4/d) . i'm not saysing it's your lens it could be different in your case .

I have a D810 and have used the TC14 II with 70-200 VR 1 no problem, also first generation 600mm F4 AFS and 105 2.8 Macro..... the TC 1.4 II supports older AF-S and new bodies for sure...
