Canon EOS on adapter?

I know this has been hashed out here before but it didn't come up easily in a search. What are the issues involved in using a Canon EOS lens on an adapter?

I assume I can buy an EOS mount say for a Letus Extreme.

The EOS lenses don't have iris rings, so does that mean it will just sit wide open all the time? Is there any way to stop down?


Any other issues?

Thanks

I have an EOS mount for my SGBlade. As you know, the canon EOS lenses don't have iris rings so you need a Canon body to change aperture. The lenses come off the camera normally wide open. To stop the lens down have the lens on the body, have the camera on then adjust your aperture. Leaving the camera on, press and hold the Depth of Field Preview button - you'll notice that now the aperture has changed. Keep holding the DOF Preview button and at the same time remove the lens. It will stay at the set aperture. This won't damage the camera but it's cumbersome to be sure. I have an old 20D body I use for this.
Red Rock has an electric module that can change the aperture on EOS lenses but I think it only works with their adapter (and it's pricey).
 
Wow that's way more than I would want to do in the field. My inquiry is not for me but for a client of mine who is buying an adapter but has also invested in Canon 5D gear (- Take that those of you who think the adapter is obsolete.) They'd like to use the canon lenses but it would be limiting to only have wide open apertures. Not impossible though.
 
Just curious, why would anyone want to use an adapter, if they already have a 5d that can shoot video? Why not just get rails and use that as their setup?
 
Higher resolvable resolution, no rolling shutter, no aliasing, no moire, a professional codec, more professional looking setup, ect., ect. ect.

Question: Why do you have to pop in here and be a dick about someone's choice of a setup?

I was just curious as to why, since I see more and more people switching over to this type of setup over getting video cameras with adapters. I've recently shot with a Canon 5dMK2 video with some Nikon primes and was amazed by the the quality of the video and this was all shot handheld. There was no malace intent in the question I asked. Therefore the last remark was uncalled for and doesn't need to be posted on a public forum.
 
I can answer for myself:

Higher resolvable resolution, no aliasing, no moire, a professional codec, easy and good audio, easy to monitor.

In both my case and the client I was researching this for the Canon is primarily used for B-roll and the adapter for interviews. They tried using the Canon for interviews and went back to the adapter on an EX-1. The Canons are great but they have their limitations for sure.

You probably haven't tried editing your footage. Good luck with that monstrosity of a workflow!
 
I hate to be a killjoy but I am sick to death of the "adapter vs DSLR" business. I started this thread so I would prefer it remain just about using EOS lenses on an adapter - i.e. - actual technical content not warring attitudes.

No disrespect to anyone who posted above.

Thanks
