Never need to upgrade.Until the next one comes along
I'm quite serious! It's like my old 501CM hassy, had everything I needed, no need to upgrade.
shhhhhh! don't let canon find out, but i feel the same way. I couple little tweaks and i'm good. they won't be selling me another camera anytime soon. currently I have a mk3 and a mk... 1 i guess, and at wedding jobs i use the mk1 just as much as the mk3.
You know, even owning 2x 5D3's, I still kinda prefer the soft, muted colors out of my 5Dc. It's the strangest thing. Check out this thread.
