Picked up the Bigma last night.
Do I need a Sigma TC on this? My Tamron doesn't seem to work on it, although it works on all my other lenses.
Thanks for the help...

If you mean "auto-focus", then no, probably none of them will - certainly none of the TCs that report effective aperture back to the camera will allow you to AF. The problem is the Bigma's small maximum aperture. The Sigma TC will work as manual focus only and as long as you don't zoom back further than 100mm. Glenn

IQ degradation was obvious with this setup. Yes you will lose AF and because the maximum aperture becomes f8 ot thereabouts you will have a very difficult time focusing even in bright light. 7D Mark II 6D 100mm f 2.8 macro 180mm f 3.5 macro, MP-E-65 300mm f 2.8 500mm f4 Tokina 10-17mm fisheye 10-22mm 17-55mm 24-105mm 70-300mm 70-200 f 2.8 Mk II 100-400mm Mk II 1.4 TCIII 2X TCIII 580EX II 430 EX II MT 24 EX Sigma 150-600
