I was SURPRISED by the RESULTS!! How the R5 Performs with old EF Lenses

I test autofocus, extenders, IQ, FPS, and IBIS in the field to see how my older Canon EF400 5.6L lens performs on the Canon R5. I hope you enjoy the photos. Cheers, Duade

Once again, excellent content! On point, no BS, nice images, great insights, great personality. You've got it. This should explode. Quality quality content. More of this on YouTube, please.

Hello from the United States. I’ve been to Australia 4 times and your country is just beautiful as r the people. Look forward to your teaching. Thanks

[birdie]

I appreciate your sharing shots that you weren’t happy with. Those birds are so brilliant. Thanks for the interesting video.

[DalsPhotography]

WONDERFUL VIDEO!, you know we don't have those worms you mentioned, but I use my mouth to make bird sining lol, and they are always curious enough as to get lots of photos :) You definetely live in a birding paradaise! And I loved the lens idea, it seems the camera worked really well with those old lenses!Congratulations! Another excellent piece of work!

[uckfayooglegay]

I really like how you show the RAW vs edited image, great idea.

[chrisipad]

Thanks Duade for this great review! I used to own this EF400 5.6L for 10 years before I switched to the RF 800mm F11 last year, and I still remember the quality and mobility of this wonderful lens!

[danielchui]

I really appreciate this video - own 400 5.6 and thinking of buying the R5 so it was so useful for me !!!

[mayhamilton]

Thanks to your videos I bought the older canon EF 400mm 5.6 lens and I've been delighted with the quality. Thanks for another great video!

[vhc]

Thank you for sharing & enjoyed the photos.

[BRIONIDESIGN]

Since you got new R7 it would be interesting to compare 400/5.6 without converters with R5 with 1.4 converter

[tintinrr]

Looking forward to seeing your review of the new R7 👍👍👍

[andreasmohrmann]

Hey Duade,
Thanks for your videos, I really appreciate.
I'm using the EF400L f5.6 on my EOS R for nature and I'm more than happy with this combination.
In the meantime, my wife bought an EF2x iii extender as a surprise for me.
Now it is my favorite nature gear EF400 with 2x extender on EOS R. Still sharp. Honestly, a bright day is not totally wrong 😉.
But with ISO-automatic and shutterspeed 1/2000 I can do handheld shots. Thank god all R-cams work fantastic with higher ISO values.
Keep on with your videos and style.
Warm regards from Germany
Andreas

Using the old lens on the r7, very happy with performance even with the 1.4 extender. Lovely light combo.

I asked this question on one of your other videos - I should have searched all your videos first lol, sorry. I’m new to your channel and I am loving your content and presentation, so relaxed and ‘down to earth’…..and of course very helpful. Thank you.

[alansach]

Yeah, I have an R6 and am very pleased with the performance of my twenty year old EF L glass. I thought it would be slow and I would just have to live with it. In my opinion they focus just as fast as they did on my DSLRs. I'm sure the new RF glass would be faster, but I can't beat the price of something I already own!

[telkirton]

Excellent video very interesting, Thanks Duade..

[jamesseward]

Thank you for answering all my questions I’ve been wondering about since the RF 800 came out. Very informative! Thanks 😊

[michaelktori]

I've just received my R6 and, when the adapter ring arrives, I'm planning to use this combination of EF400 and 1.4TC (2) and 2.0 TC (3) so this presentation was very interesting to me, thanks. I do have the Tamron 150-600 G2 but, being a little older, I find the EF400 easier to carry and always sharp as a tack even wide open! I always enjoy and benefit from your Youtubes. Big thanks.

[PaulMoorePhotography]

Really informative. I just purchased a 400mm f5.6 L USM for my R6. This video helped me understand how my X2 extender will perform and I may now purchase a X1.4 extender. I have been learning a lot from this channel and look forward to seeing more.
