I have heard some people leave a 1.4 permanently attached to this lens which might suggest hardly any IQ loss. My own experience with TC’s in the past on Canon lenses has not been a good one.

IQ is amazing! My 300mm f/4 PF is having auto focus issues so currently I'm back to using my Nikon 300mm f/4 non-VR lens coupled with the Nikon 1.4x TC. Stick with the Nikon TC if you can afford it. You will experience image degradation with the Kenko. But with the Nikon 1.4x TC, the images are fantastic!

Here is one from a couple years ago with that combo. This image has a great amount of detail.

I have that lens with the 1.4 TC always attached. It makes for a very sharp and light 420mm f/5.6. I have an old Nikon TC 14E that I found used. Note that the TC 14E III is not compatible. I highly recommend this set up unless you need VR.

Thanks for the reply. With that older Nikon TC 14E did you still have full AF on your D7100 at f5.6?

Do you know if the the TC 14e II is compatible as I can't see any mark I versions anywhere.

Mine isn't the new one - sorry, I didn't think to mention it. Mine is the Nikon AF-S Teleconverter TC-14E II.

Peter7100, yes the 1.4x ii works fine with the D7100. This chart comes from page 295 of the D7100 Owner's Manual.

I have my refurbished D7100, 300mm f/4 non-VR lens, and 1.4x TC combo ready to go take one or two pics for you. Later tonight I will try to post the SOOC NEF's and jpeg's in my Dropbox so you can look at the unedited files.
