[QUOTE="hark, post: 657603, member: 13196"] [b]Re: Staking Teleconverters - why not[/b] Just remember you will lose 3 stops of light on the long end when stacking both teleconverters. 1 stop = f/8, 2 stops = f/11, and 3 stops = f/16 That would make your 200-500mm lens shoot at f/16 when wide open instead of f/5.6. I imagine it would be difficult to see clearly with so much light loss. Since I seem to have a software issue with my D750 (and no way for Nikon to fix it), I would be leary of trying it. Even in manual focus, they will try to communicate with your camera body. Personally I wouldn't take the risk of getting a glitch.
