Thank you! I'm really glad I decided to suck it up and spend the extra money for the 5D rather than the 6D, especially since sport photography is one of the areas I enjoy the most. I don't think the 6D AF system would have cut it, although I think the 5D is smarter than I am so I still have to get used to it lol. The low light performance/high ISO noise is incredible. I was getting faster focusing and less noise with my 5D tonight at outdoor basketball games with ISO 4000+ than I was getting with my 60D at ISO 1600 or so.
With how incredible the 5D Mark III is, I can't even imagine what the 1Dx is like. I'd imagine it's the camera equivalent of sex
Enjoy. Take lots of pictures. Don't worry if the first 1,000 or 2,000 or 10,000 are bad. Just stick with it and take lots of pictures, and when you don't like a picture, try to figure out what you did wrong.
I've been having some great photography experiences lately, after taking so many awful pictures. It's like playing a guitar, practice, practice, practice. Lucky for us it's not like film anymore.
Every bad picture you take is an opportunity to figure out how to get a little better.
