  • Hey all, just changed over the backend after 15 years I figured time to give it a bit of an update, its probably gonna be a bit weird for most of you and i am sure there is a few bugs to work out but it should kinda work the same as before... hopefully :)

New Canon Speed Booster

Exactly. Such situations take up at least 80% of all shoots I've done. And having a small Atom matte box with ND filters outside where you probably have most room to move around is a non-problem. Then we have the common problem with protecting the lenses; it's more common you have elements outside that can damage the front element of the lens than in-doors, so having an ND filter in a matte box is also an insurance that your lens survives. I think in-camera and in-mount NDs are a bit overhyped. They are fast and good, but only if I'm using cheaper still lenses that already have a standard screw-on UV filter as protection.
 
I'm sorry does anybody know if this adapter clears the Komodo bottom lip?
 
If it doesn’t clear or mount solid, there is nothing stopping GDU from reshelling the things the same way they do with those canon lenses. It can’t possibly be harder to rebuild than an actual lens.

This plus an RF plate for DMC2 would make for some interesting possibilities. There are some pretty crazy full frame cinema EF primes.

Like imagine these guys with a speed booster on a s35 sensor: https://www.adorama.com/sg14135t2fce.html

Or the zooms: https://www.adorama.com/sgwfq966.html

Let alone a T1.5 prime gaining a stop.

I’d be far more interested to see what could be milked out of a DMC2 s35/8k with such a booster. Assuming the distortion isn’t too bad and/or is correctable, it would make good glass insane and cheap glass super viable.

If GDU or Duclos Lenses can do that, that would be doooope.
 
Canon mentioned it is specifically made for the C70 and will not work on the EOS R / R5 / R6. I assume it is the extra clear glass element inside the C70 that will shift the focus on Komodo / EOS R.

Sounds weird, why would it be any different from any other speed booster? The R, R5 and R6 are full-frame sensors, so they won't work with a speed booster. It's made for the C70 since it has a s35mm sensor, just like Komodo.
 
The adapter is called by Canon: Mount Adapter EF-EOS R 0.71x... note the "EF-EOS R".... not "Mount Adapter EF-EOS RF" but simply "EOS R"

But we know it won't help the R cameras in Full Frame mode, but it could in crop mode. There have been conflicting reports as to whether is can physically connect.

As long as it’s a RF to EF adapter at the core, I can’t see why it wouldn’t work on any camera with a RF mount? The only thing I can think of is the protruding mounting part that might physically hit the low lip of the Komodo. The actual mount itself should have no problem. I fail to see what in this adapter that wouldn’t work when the optical distances and needs to get a good image are equal between the two systems. And if there’s room to mount and it makes the mount rock solid, then this will be pure gold for the Komodo.
 
So, as expected, the metabones works as it should.


So if the Canon speed booster fits physically, there should be no problems. Hopefully, we could get some support on the foot as well for that.

Protection is not the the case with NDs , I know you know that, but a point is, some DPs want as much glass in front of the lens is zilch. That have nothing to do with still lenses or protection of cinema lenses. If DP wants to have anything or nothing in front of lenses its a given and not objactable.

Apparently, the Metabones EF to RF has been tested

As per the video I linked to, which is like two months old and people still say it's not supported (?)

Gotten word that the Canon also works, but not confirmed. I just don't know why people say that these won't work? I just don't understand the reasoning behind that conclusion? I can understand if the Canon mount won't push through AF functionality, but that's irrelevant with cine glass.

Here is the link where I saw the Metabones listed - KOMODO Compatible Lens Mount Adapters https://support.red.com/hc/en-us/articles/360056785753-KOMODO-Compatible-Lens-Mount-Adapters

Would love if Red could test out the Canon one and get it listed. Someone pointed out they received a test C70 with it and tried it on Komodo with no problems of connectivity or physical problems mounting it. So far so good.
I would love to see Tilta or someone else make a plate or something that can lock the foot into place so we get the canon mount rock solid. If the optical quality is as good as people say about it we essentially have a low light FF Komodo for EF lenses.

How are people not hyped up about this? :tongue_smilie:
 
So, credit to Max Bst on Facebook for uploading these. I think that settles it with the Canon adapter. It works, it's better than the Metabones and all that's missing is for someone like Tilta to design something to lock the adapter into place based on the foot on the Canon adapter.

This is a big deal in my opinion.

I believe this is a big deal as well. I don't necessarily need autofocus, but iris control is obviously a must. Looks very promising. The added stop of light is the biggest thing for me. Getting a wider image is nice too. For the projects that need a smaller hard drive footprint, this could allow me to shoot in 4k R3D with a Sigma 18-35, and it would effectively be like the original super35 crop instead of the 4k 2x crop. Thank you for your research on this Christoffer!
 
Yes, this is a huge deal.

I am a S35 fan and prefer the format and look over FF. But sometimes I just need that ultra wide shot or a bit more light. This is definitely going on my "buy" list.

If it sees and controls the aperture thats all I really need.
 
I asked earlier, but not sure anyone responded: is the optical element in these RF-FRs (both the Canon and the metabones) different from the ones in MFT/E-Mount based Focal Reducers/Speedboosters? Also does it protrude into the body/throat of the Komodo/RF mount?

Different in that Canon's is tested against their glass and has much better optical quality than the metabones. That's been a main issue for many who decided not to buy the metabones one. As for protruding into the body, yes, a little.
