Canon 5d mk3 update
Well, as a little update with my opinion on the 5dmk3. I used it first at the Mr Universe show. all day with no grip, so it was hard. But at hi iso and with a custom WB it worked great. Noise is very low. I do shoot jpeg for shows as there's little to edit or save. With grip it is now so much better. i just like the balance.
In studio shooting raw i cant really see any difference. I don't expect to really compared to the 5dmk2 which works really well in studio. Ive not tested it with outdoors or weddings yet, I actually didn't take it to the last 2 as wanted to get used to it first. The faster fps is good at shows, Ive never really needed it, but with the people who dance and move fast it did help. Yet to try the tracking focus but its not something id trust until tested well.
