I posted this to the D810 forum, but I"m not sure it got there - the board seemed a bit confused as to whether I was real or not...
In an earlier topic on Kenko tubes, I stated that neither my D810, nor my D7200 will couple the autofocus properly with any lens I've tried. My elderly D300 works perfectly, as did my even MORE elderly D2X with EVERY lens I tried......
Which got me to wondering who DOES make an extension tube set that will work properly with the "current" generation of Nikon bodies and lenses.......
SO, I just sent an email enquiry to the following companies as their addresses were found on the Internet: Xit, Neewer, Kenko, Vello
I shoot Nikon. I have a D810 and a D7200. I'll be using these tubes on EITHER body, and with a variety of lenses: Nikon 70-200 VR ED and a Nikon 105/f2.8 VR. WILL YOUR EXTENSION TUBE SET ABSOLUTELY, UNEQUIVOCALLY couple the autofocus to the D810 and the D7200 using these lenses? And by couple I mean if the lighting is adequate and the distance is within the range of the autofocus, that the camera will focus, lock and MAINTAIN focus lock on the stationary subject?
I ask because I have seen entries on the Internet that people with "modern" Nikon cameras such as the D810, and now the D7200, are finding that supposedly "fully coupled autofocus extension tubes" will NOT achieve a focus lock with these bodies.
Again, I'm presuming that the metering will work accurately, stopping down the lens as necessary. My concern is specifically the ability of your equipment to achieve accurate focus lock in autofocus mode with the above bodies and lenses.
regards,
I'm making a possibly dangerous assumption - that ALL of these companies do quality control to assure that their products work across the entire line of the equipment for which they're stated to work...
If anyone has a recommendation for other (hopefully reputable, which the ones I emailed may or may not be) companies, let me know and I'll send them an email too.
