Ok so I just got my Canon 5D mark III and I am upgrading from the t3i a bit of a learning curve.
I am having some issue I think that might be software related but I am not 100% sure.
My 5D mark III keeps freezing up the lens wont spin to focus and the menu runs slow some times. My 24-70mm 2.8 L lens works great on my t3i and for the most part on the 5D mark III but not when I can't take a picture I turn the camera off and and back on everything is good to go for awhile.
Also Last night my Canon 430exII speedlight mounted on the hotshoe in E-ttl also seemed like it was having some type of communication issue with the camera.
Does anyone know if this could be software related or is this a hardware issue ? Also what known bugs are there for the Canon 5D mark III
