We're also pretty confident that the lens on the camera is a replacement for the EF 24-105 f/4L IS.
Here's the reported “leak” of the EOS 5D Mark IV as claimed by Levi Siver. I'm not sure about this one, as I think we're still a bit early for the “official” leaks that we saw with the EOS 5D Mark III launch.
IA forum member pointed out the lens hood of the attached lens and that they couldn't identify it. We do know the soon-to-be-announced EF 16-35mm f/2.8L III has a new lens hood, the EW-88D.
I'm currently on a game drive in northern Uganda, but I figure is pass on what is claimed to be the first picture leak of the upcoming EOS 5D Mark IV.
You can read about it at EOSHD.
We know the EOS 5D Mark IV will be announced in August, with delivery coming soon after.
I have a few things about the camera that I'll be publishing soon.
