UPDATE! UPDATE! UPDATE! Thanks to a lovely commenter I've realized if you edit in DaVinci you CAN disable lens corrections if you shot your footage in RAW. I shot RAW for all my tests but I also edited in Premiere Pro where that option is not currently available. For DaVinci users, go to the raw controls and change the Decode Quality from "Canon" to "Resolve." Then the lens corrections disappear! I talked to both Canon and Adobe on the phone today and they each pointed the finger at the other. Premiere DOES have Decode settings available for other camera brands like Black Magic with BRAW files because BlackMagic created a plug-in for Premiere Pro with extra functionality, which includes many more options than just color temp and exposure. Adobe said it's Canon's call if they want to offer that support with a plug-in. Canon said it's Adobe's responsibility to interpret the metadata... in other words, it doesn't look like either is working on a solution at the moment. And no matter what NLE you use, you still can't monitor the image in the C70 without distortion correction applied.
I believe this lens uses a "reverse-zoom" design, similar to the 15-35mm f/2.8, and the EF version of the 70-200mm f/2.8. That was done so that the lens hood would be effective both at 24 and at 105 (in the case of this lens) otherwise you would see the edges of the lens hood at 24mm. This is one of those compromises in the design. The next RF 70-200mm f/2.8 which I believe will be internally-zoomed as well, will show the same characteristics. The 70mm will be towards the front, opposite to what one would expect.
From my tests --- If you shoot CRM with C70+24-105 f/2.8 you will not get lens corrections in Davinci Resolve when decode quality is set to "Full res - Resolve". The lens corrections WILL apply if decode quality is set to "Full res - Canon". But not he best implementation. For instance with nraw from Nikon Z8/Z9 there is a checbox in raw decoder wether you want the lens corrections or not.
Hello. Hope all is well with you and yours. I just wanted to say thank you for your C70 tutorial. I bought it a couple weeks ago and it has been extremely helpful.
wow thanks for doing the test and figuring it out. about to order this lens with the soon release C400. and this is good to know the lens limitation. thank you! extremely helpful
A simpler explanation of entrance pupil difference is rather simple: focus breathing, or the lack thereof in 24-105L f2.8 In fact, all lenses mark their focal length by their FOV at infinity. You used a reference photo focused on a nearby subject. The focus breathing of other lenses made them look wider, not other way around. If all lenses focused at infinity, the subject plane aka CMOS plane should stay the same.
Would you recomend this lens to my upcoming Canon C400? I was thinking going with the Sigma 24-70 Art but this gives more range and quality. What do you think?
Interesting, I’ve always set my camera on the tripod to center the image sensor. But your findings are telling me thats wrong! As a RED komodo x owner very interested (obsessed) with this lens. Ive heard good things from other owners, but looks like it would be best suited to a super 35 fov where a lot of the distortion is much more controlled. BUT since I cant actually buy this lens yet as its backordered into oblivion. I actually just made a very similar discovery on their cheapo 24-240 lens. Similar engineering decisions were made on that lens. But on my S35 sensor, it looks good and Im having a blast with the focal range. Ill make a little video about that one on my KX because I feel like its being slept on. Anyway, thanks for the info. Youre great!
Hello! Great video! Can you please measure diameters for geared rings on both - focus and zoom rings?:) Acording to tech specs - the widest diameter on the lens is 86mm, but the zoom ring is clearly smaller
Great video as usual. Appreciate the update as I’ve been considering this lens if I can save up for it, lol. If youre even in NH and need a second shooter or assistant, let me know. I’m a C70 and R5c user myself.
@@SoundItOutFilms Of course, RF 24-105/f4, I also have an EF24-105/f4 with speedbooster, but it has a critical miserable lens issue, when I zoom the lens
RED will most likely end up with a Z mount in the coming years, due to their purchase by Nikon. But of course they have a good number of RF models in production right now.
They literally just released their new flagship cameras with RF mount. Although its likely they will release a ZMount option. I do not see them abandoning the RF mount anytime in the next 5 years. Bold claim I know 😅 But for real, Jarred has been gushing about the RF mount and how awesome Canon has been doing, I think he’s been trolling Nikon lol
@@TotalRADandMORE I agree they will continue to support the RF mount on their currently released cameras. I would be surprised though if they release another camera with an RF mount. Nikon is not in the business of selling RF lenses, and they will sell more Z mount lenses by making the switch to Z mount on future cameras.
You can not disable on the c70 in raw, I only had limited time with the R5C so I feel like I can’t speak definitively on it but I believe the recording mode also made no difference to the lens corrections being greyed out on that camera as well.
This is the godfather II of gear review videos. Thanks for all your diligent work. I don’t shoot cannon but Now I understand how to figure out entrance pupil 🫡
