Been eyeing used Sigma 170-500mm APOs. For wildlife, not sports, though a bit slow for wildlife.
They come with tripod mounts. How does this work, BTW? I haven't bought a tripod yet, so wondering. You mount the lens directly on the tripod, not the camera? Is anything else, part-wise, needed? Like a tripod addition or something? Is there something one should look for in a tripod if one is going to do a fair amount lens mounting? Discovered I have still quite a few newbie questions still in me. TIA, Marnie aka Doe ;-)
