EDIT: I am reading "The IS unit is able to lock and unlock the shifting lens cell depending on the IS switch position on the lens barrel. Mechanically locking the compensation optics prevents the lens from unintentional shifts when stabilization is turned off."

That's in reference to EF lenses. RF lenses don't do that. No point in switching off IS for transport of an RF lens.

What a blast from the past! I really loved my 5D II, and with the small 40mm pancake it was surprisingly portable.

Me too! I’m team Canon but the 5D II was so great! I didn’t think I would ever upgrade. I kept it until the R5 and don’t think I will ever buy another camera until it can’t be fixed! 5D IV is my backup.

I mean, you have to build those electronic parts as well. And the design part especially looks very very complex.

Some... but Canon, e.g., builds sensors but buys DIGIC CPUs and other chips. In any case, building chips is relatively quick once the facilities are in place, while growing / polishing / preparing the big glass elements for big whites takes up to 1 year or so in certain cases and it's therefore much less scalable

I know this is a Canon enthusiast forum and likely nearly everyone here has R as their only OR primary system, but just wondering if anyone has another branded system as their primary, and the R system (any EOS R body) as their secondary system?

And why? Just out of curiosity and fun discussion.

I've shot Canon large sensor digital since '05. Been a Canon shooter since. In 2015 I started to migrate over to Fujifilm for its smaller size and to basically get into mirrorless. Also shot EOS M for a long while too.

Today my X-T5 is my primary system. I use Canon EF glass (for fun) on it and it shoots near natively in operation. But I thought why not also shoot a Canon R body for even additional options. However its still large, with EF glass especially. So it's just really a secondary/hipster case. I'm not saying one is better than the other, in fact I prefer Canon in many ways, I just overall like using a smaller system and love the Fujifilm dials and overall results. If canon made a highly polished compact APS-C system with dedicated high end APS-C primes--both with high aesthetics/materials quality/metal build, I'd go for it. But no such thing exists.

the going price on private sale has been between 700-750. i bought my last two Rs for 700 both mint, in the socal (high saturation) area.

i'm on my third R, first one got at launch then got the urge twice again after.

Ha! Assumptions on my part based ion nothing but wishful thinking - seems I wasn't wishing hard enough to shift reality.
Thanks for the useful explanation of aspects I really should have considered - much appreciated.

Thank you both - you've been most helpful.
The results I'm getting are sometimes so good I have to check to confirm I didn't have a tripod with me, but I was wondering whether I could tinker and get it even better.

Have You tested the lens with TC on a DSLR? Might be a software problem EF/RF as the RF TC works without problems. And it is unlikely both EF-TC fail at the same time.

Click to expand...

I have no DSLR on which to test it. The idea of removing the R-series body from the equation is a good one, though. I did try the EF extenders with 600/4 II on my EOS M6II, which I believe uses the standard EF communication protocol. Same result – bare lens is fine, extenders are F00. So while I agree that it's unlikely they both failed, I do think that's what happened.

I will meet up with someone who has an EF 1.4xIII at some point. In the meantime, as I suggested above I can use the RF 1.4x with the modified adapter, which is what I did yesterday morning.

My idea above that I could edit the EXIF and at least get DxO to use the lens profile for the 600/4II + EF 1.4xIII turned out to be possible with a fair bit of digging. Through some trial and error, it turned out that there is no need to change the Lens Model or Lens ID number in the EXIF, all that's needed is to set the Focal Length to 840.0 mm and set the Aperture to 5.6, then DxO correctly 'guesses' that the combo is the 600/4 II + EF 1.4xIII. (Took a bit longer to get there since Exiftool reports "Sorry, Aperture is not writable," because the real name of that field is fnumber.)

So, does it matter? The lens profile (albeit with the 'wrong' extender) corrects a very small amount of vignetting and barrel distortion (easier to see when dynamically flipping between the images rather than the static images below), but the lens-specific sharpening does make a noticeable difference. Could have gotten there by doing that manually, I suppose. The file with the original EXIF is on top, bottom panels are after changing the focal length and aperture in the EXIF metadata.



So at this point, it's mainly academic. I have a functional combination of 600/4 + 1.4x extender, and a working lens profile for easy RAW conversions. I could buy a used EF 1.4xIII (B&H has a 9+ copy for $300), but I don't really see much point.

I'll stick with using the RF 1.4x on the EF lens, and hope that Canon comes through with a new RF 600/4 with a switchable 1.4x soon. Canon, are you listening?!?

I will probably call Canon and inquire at some point, I think they still service the EF III extenders so I'll at least check repair costs to see if it's worth doing that before selling them, which would be an alternative to using them for juggling practice.

This is all very nice but...
Where is my 14mm TS-E ?
And, why not, a New FF Canonet?

If this turns out to be true, this would be an instant purchase for me. I've been using the old EF 180mm for years.

I'm new to the R1, I still have my OG R6, prior to that I used to be a 1D-X shooter.
To my surprise, apparently the R1 does not feature an in-camera trimming/cut tool to cut videos. As a wildlife shooter, I generally cut the videos in-camera, as I often need only couple of seconds from a footage and by doing so I could save up space on my hard drive. Surely, I can get around by cutting footages on my PC with a software like Loseless Cut, but I did not expect the R1 no to have that feature (lower end bodies all have that).

Also, the R1 not having waveforms is unexpected, as R5II has it.

Not being able to assign pre-capture to a button is weird, although you can get around that with different custom shooting modes. You can assign pre-recording to a button in video mode, however.

I know my R6 inside-out, the R1 is still a bit overwhelming at first, as it is highly customizable. It is definitely a most capable camera I have ever owned, though. I noticed it is far more reliable in back-lit situations than any camera I have used, I guess it has to do someting with the cross-type AF point.

Any insights from R1 users would be appreciated!

Still waiting for the unicorn to appear

the sigma 28 f1.4 art is an outstanding lens. i did sell mine tho when i switched to mirrorless in december because i got the 24 f1.4 VCM. i shoot lots of milky way

Click to expand...

I miss my 28mm Art because it was the only option, and because it was so good but, to be honest, I don't miss carrying it.
I've gone full RF since 2024. Now I only keep the adapter for the case I ever need an EF lens for work.

I agree that CE will be affected for years, but for a different reason than the implied shortage. The continuation of the AI boom is dependent on continued financing and so far a lot of the money is flowing in a loop (or not flowing at all). Nvidia invests in an AI company and then the AI company agrees to buy Nvidia GPUs, but as you say, there is no power to run the beast. They hype causes gullible investors to throw money at the AI company and by association at Nvidia, which has a completely ridiculous market cap. The timeline is too long for investor patience to last, even if there is some magic application out there that could eventually produce enough revenue to fund the monster. When the house of cards collapses, the dot com bust will look like child's play and the ensuing recession will have an effect on CE for years to come. Take pictures and invest wisely.

Click to expand...

I wasn't exactly intending to enumerate all the causes of the likely years-long implosion of consumer electronics.

I agree with the description of the AI "boom" as a venture capital scam, see here: https://pivot-to-ai.com/2025/08/23/...e-think-the-ai-bubble-keeps-going-until-2027/

And I think it will indeed keep going into 2027. If it was based on investment fundamentals in any way, it would already be over. It is not gullible investors exactly, but self-interested venture capital scammers (that's their only "innovation": endless fraud) AND plenty of idiots AND people just jumping on the bandwagon because the markets and institutional investors function on FOMO.

The memory and storage supply implosion right now is caused by AI "hyperscalers" (people hoarding chips for datacenters that aren't built and for which there is no profitable use) buying out the entire supply of memory manufacturers - there are only 3 meaningful manufacturers on earth for RAM, which was already a very corrupt cartel. When AI collapses, the likes of Micron will still have no consumer supply, so prices will stay elevated for some time (and they will try to keep them up even when supply increases as there is no competition).

"Crucial" is Micron's consumer business, which they've ended because they're making so much money on datacenter HBM, which is not usable for anything else (similar to crypto mining chips, which were sold to many of the exact same people pushing AI).

Smaller electronics retailers and product lines will be crushed because with DDR5 RAM at 5x price vs. a year ago and fast SSD storage at something like 3x, a lot of consumers simply stop buying certain things entirely. As I said the other day, I'd have bought a 2nd 4TB external SSD the other day, but it has doubled in price. It's something I could use, but will get around until I have absolutely no choice.

Anyways yes, the recession from the AI crash will also further implode consumer demand and buying power, added on top of the tariff nonsense and the monumentally stupid imperial ambitions in the middle east. Everything will be worse for consumers for a long time.

Reference material/comments:
Here's a more recent article on the bubble, the timeline, the years required to rebuild supply lines, and "hyperscalers" buying more chips than they can use purposefully: https://pivot-to-ai.com/2026/03/27/the-ai-bubble-and-the-global-polycrisis/. Ed Zitron has dug into the numbers a lot, and only 1/3rd of claimed data centers are actually being built: https://www.wheresyoured.at/the-ai-industry-is-lying-to-you/.

OpenAI shut down its Sora video slop model the other week; of course, video models are the pinnacle of setting money on fire. They still only make worthless memes, but they cost astronomically more to run than text or still image generators. This is one of the first real cracks in the glass.

I think the "Subprime AI crisis" analogy is a good one (Ed first brought it up in 2024, but his most recent article breaks down a ton of numbers here: https://www.wheresyoured.at/the-subprime-ai-crisis-is-here/).

Shucks, so no AF at ALL when using the 1.4x III.

You can AF with the combination in Live View. It’s slow, but it works. Live view works at f/11 with the 2x TC as well.

It's rough. Photographers will have nothing left to buy.

...am I the only one bothered by this unfinished, sharp-edged mounting point?

Click to expand...

It's never been a nuisance for me, never actually thought about it until seeing your post. The edges do have some rounding, and don't feel sharp against my skin. I'd really have to work hard to scratch myself.

I can see how that would scratch up some delicate surfaces, though. Or even becoming annoying when hand holding. But you can simply turn the collar, so the mount isn't sitting against a surface or resting in your hand.

Ended up getting the R6 mkiii for $2150 new in Taiwan.

"In hell, where I sent her." - Po Campo, the potential new cook in Lonesome Dove, when asked in San Antonio if he had a wife he'd miss and want to go back to when the cattle drive was halfway from Texas to Montana.

Wow you even declared it? Well done! I've bought my R52 in Tokyo and saved so so much.

- Interface

- Aspect ratio

- Sound

- Stabilisation

- Screen

-Overheating, camera noises, battery life


After all this testing I had a clearer picture in mind.
R52: very compact form factor and decent color quality that needs grading but cannot retain highlights.
6KG2: bulkier form factor with impressive dynamic range, ease of use, and color workflow.

So I have decided to try and sell the 6KG2. While I do not think that there is anything else that matches the value of what this camera can give, for my current usage, form factor is everything. I want to be able to go around with a camera and not care about focusing that much. I'll get by the awful aspect ratio and the clipped highlight. I hope that Canon will implement open gate on the Mark II and seriously improve the dynamic range on the Mark III. I beg people to stop writing that "current cameras are all great", because they are not! But the portability of them is irresistible. And while I am selling the 6KG2, I am still very interested in their new full frame model. Like I said previously in this review it has many significant upgrades: brighter screen (already present on 6K Pro), cfexpress, tracking autofocus, tighter l mount, open gate. For now I am satisfied with Canon hybrid. But if I'll ever shoot on less so run and gun scenarios, I'll definitely consider coming back to Blackmagic. Or maybe I'll not manage to sell the 6KG2 at a decent price, so I'll just keep it on a shelf most of the time and use it in those rare situations where I am sure I don't want autofocus and can tollerate the bigger profile.
