Thanks for all the advice. I may now be leaning towards the Cannon...Maybe Santa will drop a few $$ tomorrow before he retires until next year...
I'm really looking for that quality, sharp image.
One last question..If the 1.4x TC fits my camera and I do get the Canon EF 70-200mm f/2.8L IS II USM, wouldn't I lose one stop?
"The extender will cut back the amount of light by one f/stop. For example using a 1.4x teleconverter with a 300mm f/2.8 lens will effectively increase the focal length to approximately 420mm and the f/2.8 aperture will now be f/4."
Get the Canon!!! My next purchase will be the Canon 70-200!!!
