[QUOTE="GracieAllen, post: 551742, member: 41283"] I thought I put a reply in the other night, but apparently I was wrong......... Thanks for the replies... When the lens seemed so quiet and the O/S so minimal I got concerned after finding out my Sigma 50-500 doesn't use the O/S on my D7200... Fortunately, the USB dock arrived the day AFTER the lens (they shipped separately for some reason), and yesterday I had a chance to use it to alter the autofocus and the O/S. In C1 I put the most aggressive autofocus setting and the most aggressive O/S and NOW IT FEELS LIKE A "NORMAL" lens to me. I can see and hear the O/S engage and the autofocus really snaps..... Big sigh of relief....... In C2 I put the fastest autofocus and the "other" O/S setting - the one that wasn't the most aggressive or the "standard" one... It works, but I doubt that I'd ever use it... In my world chasing the birds and stuff I'm chasing I either want things to snap into place or I"m on a tripod and they're off... Which leads me to a question of "WHY?" What would possess Sigma to slow down the autofocus or make the stabilization NOT lock in aggressively? Also - I have a Nikon TC14e III teleconverter that I routinely use on my Nikon 500/f4. Rather than buying the Sigma 1.4X I thought I'd give it a try... NUH UH..... Apparently Nikon have done something so it'll only work on SOME lenses, and the Sigma AIN'T part of that "some"... I read there's a tab or some such on the mount. I've also read that "the Nikon teleconverters do NOT get along with SOME Sigma lenses." So, I'm curious - is it a reasonable thing to find and remove the offending tab from the Nikon TC or will performance be significantly better with the Sigma 1.4X on the Sigma lens? OR, is it a total waste of time 'cause even the D810 IS NOT going to autofocus worth a darn with the Sigma 150-600 and ANY 1.4X?
