I'm pretty sure the answer to that is in the amazing lack of noise in those photos. Whether I'll be happy with less reach remains to be seen. I have a hunch I'll forget about that just as quickly as I forgot about the extra weight and size.
I'm really anxious to try this out on volleyball, but of course won't have a game until next Wednesday. I know it's not a camera recommended for sports, but if focus and burst are at least as decent as the T2i, that will be fine. I was struggling mostly with wanting to go over ISO 3200 but knowing I wouldn't be happy with the images if I did.
More than anything, I can't wait to be sitting on Main Street at DL shooting the night time Christmas parade. That is going to be a real treat.
