Really great explanation of the various adapters, thank you so much! I don't even have an R series camera, just the original 5D DSLR which is becoming hard to use, but was wondering whether to sell all my cherished EF lenses and now I see I don't have to.

Learned something new about these adapters. I don't remember anyone else saying that the adapter also had the rubber seal to keep the weather sealing from the lens. That's good to know.

Well, that was quite a review! Hope your channel grows fast.

so glad there is this. It will enable me to get the cheaper used Ef 24-70 mm 2.8 lens for my new mirrorless. Huge massive relief! still a bit more than getting the f4 lens but 2.8 is so much better

To the point, tell it as it is. That you did . Excellent video, Man. Thanks

I upgraded to a R6mkII and purchased both a Canon EF-RF adapter and a Meike EF-RF NVD. I purchased the one with the VND when shooting video because it is more convenient to adjust exposure via the VND on the adapter vs filters on the end of the lens.

Love your vlogs Cody, they’ve really helped as I’m also a 80 d user but would like a mirrorless canon ..keep up the great work as it’s really helping me .Thank you x

[BDNADLER]

I bought the EF/RF adapter with the control ring. I am going to order a second one, as I have a second Canon mirrorless on order.

hi cody, a very informative vid (:
i was considering the R6 mk ii, but came across your review on the R.
now, im seriously thinking of getting the R after using the 6D for a decade !

[v_stands_for_value]

The ND one sounds like the best thing ever in the world, one filter size for all the lenses no matter the end diameter

[billgirolamo]

Struggling with parting with my EF lenses 2 of which are brand new but this helps .. thank you Cody!!

I’m surprised at how small your channel is! Greta video. I’ve just traded my 6D in for the R and I look forward to getting it soon. Managed to get an adapter for £70 :D

Brilliant, thanks so much for all of the detail. I've got my original Sigma 18-250mm all-round lens that is really good, so will use the adaptor for that. I'm not exactly sure what the control ring does on the adaptor but will look into it.

Thanks for the detailed explanation on this! I have a Rebel T7 and starting to outgrow it already after a year of use, thinking of moving to an R50 but my budget doesn’t call for getting another set of lens again, haha!

[forsgren]

Thank you for the straight on information. Rock on, bro! 🤘

[mellopup]

Super informative, thank you so much!

I just found this video and found it very helpful. I currently have a Canon 70D with a nice Canon zoom EF 70-200 1: 2.8 L IS USM lens and a Sigma 24-70 2.8 EX DG lens. Bought lenses over 10 years ago, bit the canon lens has barely been used. I plan on getting the Canon R6 M2 and will get the adapter. Buying new RF glass is just not worth it to me, at least not in the near future. Thank you for the video.

[santinomarella]

I’m surprised that this video does not mention image quality - and even more so that I couldn’t find anybody in the comments that mentioned it either.

As an EF lens with the lens mount is maybe around 2cm further from the sensor compared to a native RF, does the image quality decrease? E.g. sharpness and another unwanted effects such as vignetting.

[stonefamilyadventure]

Thank you so much. Your video was exactly what I needed! I upgraded to the R6 which arrived the day before I had 4 football teams scheduled just to find out my existing lenses weren't compatible. 😢

They're rescheduled now but I wasn't sure if I could use the same lenses with an adaptor or needed to spend thousands on new lenses.

You've saved me so much money. Thank you again!

[mk-escapades]

Thanks for this Cody, I'm starting to do research into upgrading from my 5d Mkiii to an R5, and was worrying about if I can use all my lenses or not. One question I have is if you ever thought the adapter acts like an extension tube, since those are just empty tubes too. I understand that the extension tube doesn't have the adapter functionality, but i wonder if the adapter could cause any f/stop differences by not allowing as much light to the sensor like a tube would.
