Frank, Thank You. That is exactly the kind of guidance I'm looking for.
In reply to:
I’ve later learned that even with the Sigma 18-200mm lens, I can compensate for poor lighting somewhat by switching to manual mode on the camera and adjusting the ISO and aperture settings. Still, there’s no substitute for good lighting or big lenses.
Very interesting, indeed. Do you find that you get "acceptable" results this way, or just "better"? What aperture/ISO do you use? Is it a PITA to make these adjustments on the Canon?
That Canon lens you linked to is nuts. I'd never get the value out of it. I don't want to spend the money on prime lenses, but it is beginning to sound like that might be the only strategy to get the results I want.
