Hey folks, question about long telephoto work. Is it better to use a teleconverter or crop your photo down? With a teleconverter, you could get the framing right, but at the cost of speed and noise (any other cons?). Without it, you would have a probably better quality photo, but would then need to crop down. Which would you rather do, and why? If you need an example, just go with a 400mm f/4, either using a teleconverter or cropping down.
