However, today's EVF technology is not at the level when it is actually better than the OVF (yet). But I'm sure it will evolve and replace the pentaprism in the future. The problem is that nobody knows when that future is coming till it's already here. Finally, 5D won't become a camcorder no matter what your dreams are, it's a DSLR. Just wait for Canon to release a FF something which will be THE camera for videos.^ an evf will ruin the 5d line evf flickr and are unprofessional I prefer optical viewfinders but thats just me.and you are not alone
Things heard in the past
1) Film is better, digital is unprofessional
2) Auto focus is unprofessional. Manual focus in what the Pros do.
3) Electronic aperture is for amateurs. I need the aperture ring.
Now, most people now will not go back to film, want their 90 point autofocus and all the exposure features that electronic aperture offer. And SOON, people will think the same thing about EVFs. They will say, how did I ever live without it? Why? Because EVFs allows a much broader range of useable lenses, much better judging of exposure and from what I understand (I might be wrong) a faster burst speed (like the new Sonys) which is only possible without the mirror.
Ironically, I shoot video so I don't use auto focus, I would prefer a manual aperture ring for more universal adaption. But I want an EVF because of benefits mentioned above, especially quicker snap judgement of exposure without relying so much on the meter when doing things Manual, which is what I almost always do.
Just like all other aspects of a modern camera, electronics will over take the OVF and in hindsight, people will embrace it and learn to like it.
You know what's strange is that after shooting video with the Canon DSLRs, I now way prefer the DSLR form factor for shooting video. I've owned video cameras, a 16mm Eclair ACL and a Beaulieu super 8mm and the DSLR is so small and easy to shoot with, form factor wise, especially for hand held type stuff where often now, I just pull out the slack in the neck strap and it because a super stable rig of sorts, and you can do it quickly if you're shooting b-roll without setting up a rig. You just have so many options with DSLRs in terms of how to outfit it.
It's nice because you can add rigs and what not to make the DSLR as big and gadgety as you want, but it can be stripped all the way down to a simple, small camera; and that is something you just can't do with the larger video cameras.
The only reason why video people love the 5D is because it's the only Full Frame video camera so it has that special look that you can't get with other cameras.
Mostly, I just want the thing to come out. Tired of waiting like everyone else.
