Red Rock Canon Live Lens Mount real world test

Hey all,


Red Rock Micro recently sent me a production model of the Canon Live Lens mount to test. I want to give some quick notes from my testing and I hope to post more about it after I shoot with it again this week.


Its really a wonderfully made device that does a very core function that is needed by so many people with Canon lenses.


What is does is control the electronic aperture of the canon lenses to allow you to set the f-stop. Not to minimize this but that is the only function it serves. It does not control AF or IS or any other lens functions. But that is enough to make this an amazing device to add to your kit especially at the price point they have been talking. I for one, probably wouldnt use these other functions anyhow.


Its a rock solid build. The unit I was sent actually had one loose screw which made me think it was a very loose mount with a lot of play - however, once I discovered this and tightened it, the mount was rock solid on both the camera and lens side - very nicely machined. I have also been assured by Red Rock that loose screw will not be an issue on actual sold units so I wouldnt worry about it - and it was easy to fix.


Once the lens is attached you can change the aperture via 2 buttons - one up and one down. The unit is powered by a 9 volt battery attached via a cable. While I wish the battery compartment was built in, I suspect this design is so the battery compartment doesnt get in the way of the camera setup (follow focus, rails etc). Doing it this way keeps the footprint smaller.


Once minor omission I wish they had was a lit screen for the aperture readings since so many sets are dark but this is really a minor issue being that all camera operators and assistance should have a small penlight on them.


I have used this with primes, cheap zooms and even the Canon 70-200 big boy lens. They all worked flawlessly and held aperture to the precise setting. The latter lens required a lens support which would be expected at its weight.


This is the first device to be coming to market and isnt vaporware that does what we all needed and have been waiting for. Now you can take those Canon lens, be it low end or L-series, and use them on your AF100 or whatever camera that can take a 4/3 mount. Its gonna improve your kit tremendously and will be well worth the price. I will be using this for sure.
 
Does anyone know if these kinds of electronic lens mounts would ever be able to work with lenses' distance scale and focussing controls to provide off-board control of the focus?

If it were possible to electronically communicate with these lenses and use something like 360 degrees of rotation from an electronic follow-focus to provide more precise focus control in operation (a function which in the past has only been possible mechanically with cinema lenses designed for a long focus throw), it would be amazing.
 
here is an official picture red rock sent me - I can confirm that the adapter does indeed look exactly like this in its full production form.

ill check on the exact levels of adjustments next time i test with it - I know it was sub f-stop but am not sure if it was thirds or fifths
 
We're not seeing anything new from what we saw at NAB last April. I'm wondering what the hold up was in releasing since there isn't much difference from the NAB proto. Kind of a let down for me. I am glad this is getting released and what it can do for us AF100/EOS lens owners but an external 9V battery is bush league for RedRock. I expect more from them. I think they should have at least pulled power from the camera. If this unit is going to be priced at $500 then I think that's a little high. I'll probably wait for the Birger.
 
I have to agree with DustBowl. We've waited almost 5 months since NAB and all we have is a review that talks about a loose screw, a handout photo and a tester not sure about the degree of f/stop change available. Looks like nothing has changed since we saw the prototype and we still don't know the unit price. There's something to be said for having Barry Green, or someone at his level, do qualitative tests on these new products. Perhaps Brian Valente from RedRock could weigh in here as well.

Just give us some timely, accurate facts.

hey snp - please dont tune into this thread if I post more details. I can post photos, and will, and will check the exact f stop changes and can answer any questions. But luckily I dont need to flame on this thread cause you got that covered. Whew, glad thats off my plate
 
Hey smelni!

Thanks for the info. Did they say anything about this adapter also being fitted for other cameras as well, like the F3 and FS100?

Thanks!
Rick
 
Rick - I didnt really have a conversation about that with them so I cant say either way - What I can say is that when this adapter starts being sold we finally have a solution we needed to use canon lenses on the af100 just like we do nikon and any other lenses that dont automatically communicate with the camera. And thats awesome
 
I can certainly contact them about it myself, however, if you do talk to them, mind just asking if they have any plans for it? :) Just curious. And I agree, it is an awesome thing.
 
will do - i wonder if there is a physical micro 4/3 adapter that you could use to attach this to those cameras - since there is no talking to the camera via this adapter that might be a good solution
 
That's a good point. I'll have to look into that if this comes out sooner rather than later. Man, the first of these companies to get these out the door are going to make a killing. I bet Canon glass sales go up as well :)
