Hi all,
I had a shower thought today that I might go forward and explore for myself. If you have any thoughts on the matter (or experience) please share it!
My thinking goes like this:
There are plentiful and cheap teleconverters available in k mount that are only K
AF. These teleconverters have all the data pins of the current iteration of the k mount as well as the screw drive socket for F and Fa series lenses. What they lack are the power zoom / SDM contact pads of the later K
AF2 mount. Because of this, such teleconverters are unable to drive autofocus on lenses that rely on lens based af motors.
Could an adequately motivated person add the SDM pins to one of these K
AF teleconverters to create a homebrew K
AF2 version?
I was planning on giving it a shot and making a proof of concept prototype with my Sigma 1.4x DG using sugru, soldering wire, and patience.
Any thoughts?
