New Electronic EF Adapter from MTF

[KMA_WWC]

Hello everyone, just got an email from MTF services about their new electronic adapter and controller. Basically it's out on their new website. Here is the link: http://www.lensadaptor.com/adaptors?lens_fit=All&camera_fit=31

Do you have to use that large box controller in conjunction with the MTF adaptor? Seems really bulky compared to the super simple Metabones adaptor.

Unfortunately yes. I know that metabones adapter is smaller and cheaper but i think this one compatible with more lenses and more superb. No connection errors, no IS errors and staff like that. but its my opinion.

Looks like something youd only use on sticks....

The metabones adapter already allows you to control the aperture in 1/8 stops.

Eye watering price!

Better value can be had elsewhere. MTF are having a laugh.

The fs100 only report changes in 1/3 stop. however, when you scroll the iris well, you can easilly see about 2 other steps before the camera show the next 1/3 stop. I don't know if it is clear, I will shoot something to demonstrate it.

The new metabones with anti reflexion material in the inside dosen't flare more or less that my dumb adapter.

I just shot a quick video with my iPhone to illustrate the 1/8 stop change: https://vimeo.com/41028092

Thanks, Jean-Philippe, you explained it perfectly. That's great to know. I have a "dumb" MTF adapter and like that it doesn't flare due to internal reflections in the way the metabones is reported to do. I would imagine the new MTF will also not flare. Whether that is worth the price difference is hard to say.

Edit: Sorry, just saw the reply above.

Metabones doesn't have "internal reflections". It was only a problem with a very few early version of the adapter, but the issue is fixed.

it's mind boggling to me why mtf even released this. i don't see an upside to this one from the metabones. ok maybe it's a little more solid as they have a great reputation for making great gear. however, the giant box and huge price tag offset the pros by a mile. when i first looked at it, i got excited because i thought that huge box was a focus controller. bummer. c'mon BIRGER!!!!

Beauty of the free market- vote with your pockets guys. I for one wish them the best with it....

This so true. Didn't mean to start a war between those two adapters. Just wanted to let people know that is out there.

With this adapter (and other similar) can you pull iris live in a smooth manner?

not with canon glass... the stops are set and will jump between them. i don't think anyone has figured a way around this or if it's even possible...

Regular Canon EF lenses are equipped with electromagnetic aperture diaphragms of 1/8 stop resolution. A 1/8 stop change is certainly visible in your footage. (Both exposure-wise, and bokeh-wise.) We've got to remember that over the last 20 years these have been still photography lenses and their cinematographic use is relatively recent phenomenon.

Not having a C300, I am not sure if Canon has updated their cinematographic lenses lineup with stepless aperture and added extensions to the lens communication protocol accordingly. (I suspect they have, but couldn't confirm in their literature and annoucements.)

As you can imagine, short of physically modifying the lens, there is no way to lift this 1/8 stop restriction. It has something to do with the lens itself, regardless of whether it sits on a RED, an MTF, a Metabones, or the upcoming Birger, or a Canon itself!
