Great video Paule! Enjoyed watching your tests. Nice work!

It softens the image beautifully as well ever so subtle but noticeable

Excellent video, you touched on all the important points. I recently got this as well for the Komodo, and I am very happy - more light, wider fov for 4k 60, and IS / auto focus is great. 16-35 F4 lens works great

Hi Paule, nice video. The slight reduction of sharpness on the edges is probably not the speedbooster, it's the lens. Obviously you are using the whole lens and even a bit more as its 0.95 crop so the lens will always be a little soft especially wide open. When not using the speedbooster you are only using the central part of the lens which explains the sharper results. I use this adapter with my C70 and its amazing.

Thank you for creating such an in depth video on this, you answered every question that came to mind!

I think that given all of the money in the world, this would be my go-to camera combo. You essentially get an ultra-portable Red full frame camera with autofocus and global shutter and compatibility with 3rd party accessories for under $7K. I hope Red releases a successor to the Komodo so that the Komodo drops a tiny bit more in price so that it's within my range.

Excellent Review! Very informative and because of your review, I will definitely purchase this with my Komodo!

I was so curious about whether or not the lens IS would work with this adapter on the RED! So happy to hear it does work! Thank you.

this video did it for me, I will be purchasing one for my RED Komodo. Thank you! 🙏🏼🔥

Excellent review and as I was watching this I was thinking "the 24-70 would be great with this," and then you showed the IS test! Haha. Love it. Thanks for this video

Yesss! The video I been waiting for. Thank you for this.

thank you for the deep test, really helps !

Thanks man, great content.

Great Review Thank you for These Tests.

Hi Paule, great review and thanks for doing a detailed review. I'm still waiting for my Canon Speed-Booster ... Products take a while to get to New Zealand 🤪

Cool! Biggest downside for me is that you can't put a variety ND between the lens and the body any longer..

I used the Metabones 0.64 XL for a while and it is also very good. The only issue I had was when the lens was under f2.0 it would cause a really odd soft focus look. Otherwise it was fine.

Great review but there is one mistake. You coomparing corners in speedbooster to cropped wide lens. It's obvious that it has much softer corners than center of the optics. I think corners are not that bad if you compare to other ff camera. This is limitation of the lens itself.

Thanks Paule! Great tests! Is there a way to support the speedbooster, like connect it to the plate you have for example?

Very interesting and accurate review. Do you think it’s worth spend those money on a speed booster if I ha only have one EF lens ?

Hey. So I really like the idea of a 24-70 but I would like to have auto focus as well as in body stabilization as I do music video as a one man team and a lot of handheld work. I can’t for the life of me figure out which lens to pair this speed booster with on the Komodo that fits that criteria and has usable auto focus as well as stabilization. I was aiming towards the Tamron but quickly found out the auto focus doesn’t work with this adapter. I could really use any help at all! Also budget isn’t really an issue for me but I don’t want a cine lens. Thanks again and amazing In depth video!

Really like all your content (and improving my German on you other channel)

Hi Paule, thanks for all these videos, good evaluations and your videos are on point with issues that help in making decisions about this equipment. This is more of a general question than related to the focal reducer, although touches on that. I have used an EOS R for a while and am very happy with the image quality. I just purchased the C70 to use as a master shot for interviews in multi cam setups with my EOS R and I feel like the C70 image has more of a flat feel to it and just doesn't have the separation of the subject from the background that I get with my EOS R with the same lens and the sharpness of the image is a bit lacking, so when I switch back and forth between the angles it just has a different feel to it that is a bit disruptive. I know some of this is related to the Super 35 vs full frame sensor but I'm wondering what your thoughts are concerning cutting in footage from the R6 and the C70, do you find the feel is different? And do you feel that the speed booster helps with making the footage more similar looking? Are there settings that you use to help if you use the camera in this way? From the R6 clip you used in this it does look a bit like the same difference. Any insight you had would be appreciated if you can speak from your experience with this. Thanks!

Thanks man, that really helped me Taking a decision.

Great vid! I decided I'm going to build my whole kit one thing at a time based solely on your videos. If you never do a video about tripods, I just won't ever get one but I'll pretend like it's my "aesthetic choice".

Thank you very much for the review. Great

where do you get the @/canon0​.71x focal reducer?

Does your 24-70 Tamron work with the Komodo’s Autofocus? Mine performs horribly. Gets stuck hunting constantly. Thanks!

Can you control the iris/ f stop using the speedbooster? I heard the metabones one can

Excellent video

Thank you for this informative video! I purchased the Canon focal reducer, partially based on this video, and couldn't be happier. That said, I have to ask you: Does the autofocus work for you on the Komodo with the Tamron 24-70mm F2.8 G2? I have that lens too, but I'm having a hard time controlling it from the Komodo or using it with Autofocus on the Komodo, both with the stock adaptor supplied with the camera and with that Canon focal reducer. For me, both the Tamron lenses (24-70mm + 70-200mm) and the Tokina 11-20mm F2.8, are stuttering when Komodo tries to control them wither through Autofocus or when driving manual focus through the Red Control app. I wonder if you are having the same issue.

In your IS test section you said you were using a Tamron 24-70? Was this the Tamron SP 24-70mm f/2.8 Di VC USD G2? I ask because i would like to get this lens but several people have posted on facebook saying it does not work on komodo?

Also, when will your Komodo review be out? Curious as to why you chose it over all of the other options!

I'm wondering what about if you need NDs? you'll take like screw on filters? Cause Matte Box will probably result in reflections that you don't want between the 2 glass elements. It feels like I would go with the Kippertie Revolva for NDs but then, no Focal Reducer... thoughts?

Thank you - great review! Does images stabilization on the Tamron work with the metabones rf-ef? Or is it only the auto focus that doesn't work?

4.01 - look at the difference in the way the face is rendered on full-frame - much flatter. Thanks for not saying the speed booster makes it full-frame. Nice review thanks.

How are you getting a lesser crop in 4K mode ? A Focal Reducer reduces the focal length of the 50mm x .71 and now the 50mm is like 35.5mm. If you had used the 35.5mm lens you would get the same. Why do you have to use a lens and make it wider with a speed booster where you could just use a wider lens - Unless your goal is to get more light or brighter image !

Does this work with the Sigma 18-35? Or does the lens in front have to be full frame coverage?

Hi Paule, I want to use this with the Irix 45 mm T 1.5 - It's a big and heavy cinema lens, about 1.1 kg or 2.4 lbs, so I'm mainly concerned about the sturdiness of the mounts. I mean both the RF mount on the Komodo itself, then the other two mounts on the speedbooster. What is your take on this?

GREAT VIDEO NICE JOB

can you use focal reducer with cine lens?

Hi. Have you tested the focal reducer at wide open f1.4 or wider? Is it still sharp?

Great video, thanks :) Do you think this would communicate (AF etc) with the Sigma Art 18-35 and 50-100mm? (On the Red Komodo). Thanks

Hi Paule, the Metabones speed booster is cheaper, so is there a reason to pick the Canon one for the Komodo?

Does it work with prime lenses? I have couple sigma primes.

This is my question. Do we have to buy a ND filter for this as well or can we use the ND that I bought with the EF adapter on the Komodo? I bought the camera with that adapter w ND Or does this stack onto the canon EF adapter?

Which nato rail did you attach to the top of your outrigger handle at 5:27?

this focal reducer + a 24-70 f2.8 L EF (and no IS), or a RF 24-70 2.8 IS for a red Komodo (and I'll be likely moving to a canon photo body to use the lens for both photo and video)?

Great video man, so about Sigma Art 18:35 with the adapter?

Where is the link to buy one

how do you secure it to the camera cage, and is it even possible to secure it to the cage?

Can you stack it with the canon variable nd adapter?

is the OIS working with sigma lens?

Does it work with any cine zoom?

Can it be used with EF-RF adapter on R5?

just got the idea lol and found your video

Will this work with the Red scarlet w?

who in the film world actually cares around a perfectly sharp image though...?

Sorry, but that adapter looks awful.
