Phil's Cine RF Mount & Adapter F.A.Q.

[Ryan Genova]

Has anyone tested ef lenses like the sigma art series on the metabones speedbooster on the komodo? Can you change the iris? Or is it not electronically communicating with komodo ?

I've tried it, but the Speed Booster isn't communicating with Komodo right now. Manual focus, manual aperture lenses work great though with no vignetting.

 

[Ryan Genova]

I've missed some forum posts since I got my Stormtrooper a couple months ago, so I may have missed something, but is there any timeline for electronic RF lens support? Really looking forward to using the great Canon RF lenses on Komodo. I've done some tests with the RF 50mm ("tricked" to work on Komodo by setting aperture and focus on an EOS R body) and it looks great.

How did the autofocus function? Was the AF better with the RF lenses compared to EF?

RF lenses can't be controlled by the Komodo. It sounds like Ryan was doing the same trick to what was done years ago with EF lenses before everyone cracked the control protocols, where the aperture was set on a Canon camera, removed and placed on the adapter on whatever other camera.

For those concerned about native RF Mount electronic Iris and Focus support, Jarred just shared this:

And just based on my personal experience of DSMC and DSMC2 along the way. RED isn't Canon, so they have to do all the figuring out when it comes to the EF and RF protocols. Then of course thoroughly testing. Long time RED shooters know that journey well and RF being brand spanking new, this is encouraging news.

Especially for some of the upcoming RF autofocus/electronic disco lenses on the way.

 

[Anthony Howard-Crow]

Damn, thats awesome! And a looking promising in a much quicker timeframe than i had imagined.

They haven't shipped yet, but standby.

Do you have any idea on the quality of the Breakthrough NDs vs the NDs that ar din the Kippertie?

 

[Berto Centofante]

I just received my Komodo today and can't wait to use it. Still waiting for my canon batteries to be shipped but the power cable works for now. I have a canon 70-200 rf lense and would love to use it. It seemed like the inability to control the aperture renders it useless for now. Any idea when that will be working ?

Congrats Berto!! Did you receive the normal black version? When did you order? Just curious!

Question;
I use B4 lens. There are some dumb ebay
Eos r adapters for B4 lens.
I manual iris and do not demand auto focus.
I currently use dumb mtf to B4 on my JVC LS300 but
It's 4k, I need 6k 29.97. Would a dummy eos r b4 HJ 21 function on the production Komodo? With its supplied e0s r adapter ? I've found that S35 is perfect for B4 in extender mode which yields 82 percent of sensor. I'd hate to buy Mft mounted Z S6.

 

[Christopher A. Bell]

Something to keep in mind: B4 lenses are designed to work with 3-chip cameras that have a prism splitting the incoming light into RGB for the individual red, green and blue chips. Quality B4-to-larger(er) sensor adapters(like the IBE HDx35) have optics that are not only blowing up the image to cover the larger chip, they are also correcting the image for single chip cameras.

 

[Patrick Forestell]

Thank you, the adapter you noted is bulky & $$$$, I haven't seen any significant artifacts from using an HJ lens on a single 4k sensor. I was interested in whether or not the Red Komodo RF to EOS R adapter would physically accept a none optical corrected (dumb) EOS R to B4 lens ?

Looks like a dummy Pl to B4 adapter ?

Feels like worth a post here.

Just mentioned that I like to consolidate with various lenses with different mounts to adapt to things like EF. This was obvious during the last decade here with my Leica, Olympus, Nikon, M42, etc glass being put directly onto DSMC/DSMC2 EF Mounts. The cool thing about still going to EF is using the behind the lens ND adapters, Helicoid adapters, and other special mounts that go from RF to EF. The only concession I really make is Leica-M mount as that can't go to EF and also is just a shorter adapter anyways.

Another noteworthy thing I should mention. I have now seen all of the current and soon to be released Canon RF lenses. Mostly to test out and I have begun my journey into kitting up native RF mount glass for myself. Don't think I'll have as many as my EF lenses, I have most of Canon's L glass and a bunch of others, but I do want to explore a few of the newer optics. Some of which have been hard to source during the pandemic. Got a few 3rd party RF lenses here too. Looking to dive into that Kipon set at some point as well as it's a nice range. Hoping Sigma, Zeiss, and even Tokina come to play in the RF arena. I fear in some cases they may be beaten to the market by some other offerings which might impact long term plans, but who the hell knows.

There's now 7 RF Mount cameras on the market stretching many price points. I suspect we'll get to 9 or 10 cameras pretty quickly on into 2021. So yeah, more 3rd party lens support would be wonderful. Also hoping after the 35mm f/1.2 that Canon goes "full hog" and makes the 24mm RF a f/1.2 L as well. I could also see a companion zoom to the 28-70mm f/2 like a 70-200mm f/2 though it will be larger. They have some f/4 zooms coming and it appears some more cinema minded RF lenses too. But I'm hoping, big hoping they hunker down and make something like a 24-135 or 28-135 f/2.8 perhaps even f/4. They'll likely make a prestige prime in there at some point like a 50mm f/1. Hoping for some proper pancakes too. Likely lots of new Canon made stuff whatever the case.

Remember most RF lenses were released in 2019 and 2020 with only a couple from 2018. Really new still, but it's a growing little world between C and 3rd parties.

There's been hints at RF support coming relatively soon via Firmware Update on Komodo online. That's going to be huge when it drops. I would expect the 24-105mm f/4L being pretty darn popular once that support is in there. And I'd kill for it to be an 18-105, but whatever

Again, thanks Phil for the incredible resource that is this thread!
Just to report on the snippet I quoted; FW 1.4.0 comes with RF support.
And while still in Beta, AF works smooth as butter, especially on the RF 24-105mm f/4L IS.
IS works and registers as ON/OFF with the Komodo.

That's my new favourite setup!

Please note: NO control ring - to anyone interested, probably you should just forget it's there.

I got my Canon 0.71x RF-EF Speed Booster yesterday and tried a few of my lenses on it.

The bad news is that if you are using Contax Zeiss vintage lenses with Leitax mounts, they extend too deep into the EF well and won't allow infinity focus before they touch the glass of the adapter.

Basically, if your lenses aren't 100% in spec for EF well depth (basically no more than the depth of the EF lens contact raised area, AT MOST), then they won't work.

My Sigma FF 50mm T1.5 Cine prime lens works fine, so for modern lenses it's probably OK as long as they are in spec.

Be careful when testing your own vintage lenses and mount them with a focus set that has the back element already further forward (ie not at infinity) and GENTLY turn towards infinity, stopping the instant you feel resistance.

Hope this helps some of you make the decision to buy (or not).

Cheers,

Paul

Wondering if that’s the case for all Contax Zeiss lenses or just certain ones? I hear that the Leica R 19mm and 24mm run into clearance issues but that the 35mm and 50mm summicrons are fine.

 

[Paul McGuigan]

This site is a great resource for virgin Red owners.

I have a question..if using a native RF mount lens, are there any solutions for behind the lens ND's?

TIA.

Paul

The 50mm f2 and 90mm f2 work (those are the only two Leica R series I have). Can't say about the rest. The Canon Speed booster lens protrudes almost to the EF mount itself, so any depth into that area causes the adapted lens not to focus to infinity.
