[QUOTE="J-see, post: 458240, member: 31330"] The problem with the TC2.0 isn't just the quality loss but the fact AF works at f/8 which really is too slow for anything that moves. For static shots it would matter less but 500$ is a lot for only that. The TC1.7 isn't much better when it comes to that. It's also pretty slow. If I would buy a TC for the lens, I'd get the 1.4. The quality isn't much lower than without the TC and you still got a decent focus speed. The lens is pretty sharp and I can easily crop to 100% which is quite some on the D810. It should not be much different with the TC1.4. I never tested it but I suspect that in the end cropping the TC1.4 outclasses the increased reach of the 1.7. The 2.0, even when I got it, I'd not advise at all. At least not when you want to use it on anything that moves. [/QUOTE]
