Not a professional, so you can totally ignore my comment, but I don't see anything in your photo or video needs that would require either the R5 or R5C, so I would recommend saving a few dollars and take a look at the R6. Unless you're doing wildlife, or other types of shots that need a lot of cropping, I think the R6 will be absolutely fine.

Two cameras in one!

It's still the same. The limitation is the sensor and the 12bit ADC

Now I'm thinking if it could be possible to port CRL LT to Canon R6. It has dual SD and supports V90 cards. We have to dream these difficult times... it's good for our health hehe!

Good quality like M6II (skipping/binning then upsample) or like 90D (proper downsample)?

Click to expand...

Where can i find more info about this difference? Lately i've come to realize that the 90D is far superior in the video dept than the M6ii.

I’d suggest her PP techniques too. I’ve seen some of her shots taken on an EF 70-200 F/4 L ……

??? Canon had a 50/0.95 for its rangefinders for like 20 years at that point, and 50/0.7's existed even if in small numbers.

Click to expand...

I was talking about an SLR mount. Funnily enough, I used to have a 50mm .95 range finder lens for a while...a long time ago. My point was...if Canon wanted to release new exciting glass...they did it before with the EF mount and the 50mm f1.2...why couldn't Canon do the same for the RF mount? Why not a rf 35mm f1.0? Even expanding the f1.2 range would be a revolution.

Thanks, Alan. She likes birding but only has an R and now that you've got me thinking in this direction I started checking reviews. This one claims AF is a pain with the R but I think that's more of an indictment of the R vs. R5.

Good For Birds? Canon RF 100-400mm f5.6-8 IS USM Review

The Canon RF 100-400mm f5.6-8 IS USM lens is capable with the right camera. But it's a very odd choice overall in the system.

Yes, it’s the R. The 100-500mm has turgid AF on the R according to some reliable reviewers but stellar on the R5 and 6.

That is like saying that if Angénieux bundled the Ronin 3D focus system with their lenses they were now making auto focus lenses. Ya, OK, sure. But that is one heck of a stretching of what an autofocus lens is.

Click to expand...

The servo's are just in different places... "AF" lenses aren't making the decisions all by themselves. The camera is and then sending signals to drive the servos to move the lens elements into the proper position. We've had similar discussions on professional boards many times. Pretty much any lens could be turned into an "AF lens" if a manufacturer decided to implement it in their cameras. Yes, there is a little more to it than just saying it, but at its most base, they just have to interface it with external servos that will drive the lens.

This is an awesome thread, and you guys are simply wonderful for sharing your knowledge and best practices! As some of you may know, I've been having a devil of a time trying to get my R3 to focus on a wide variety of things.

As it turns out, how we work with lines and contrast appears to matter a lot more in our R3s than I ever consciously noticed during my 1Dx years.

The following video was recently sent to me as an FYI to help with my focusing. Putting aside all the sensor talk on the pros and cons of different designs, the tip that Tony shares at the 2 minute and 20 second mark in his video is significantly helping me to attain focus. The tip to help with focusing: "just tilt the camera a little bit". That is most certainly something I never, ever, did with my 1Dx to put things into focus, but I now find myself needing to do it often with my R3.

Case in point, I just tried to photograph my diploma hanging on the wall. When my camera is horizontal, I simply cannot get my diploma to focus - using any number of focus activation techniques or button approaches. Yet, when I tipped my camera a bit, voila, it work. That's just nuts. Hope this helps you as much as it helped me. Are you guys doing camera tilts in your work to focus things?

This statement is not true when using a debit card. Yes, technically, they don't actually remove the money, but the bank puts a hold on the full amount so I cannot access it...

Click to expand...

Of course if you are a richperson then it probably doesn't matter if they put a hold on the money.

I do not understand though why anyone uses a debit card for online purchases. It seems fraught with peril to me. It's one thing to have a charge card number pilfered, but that usually results in a minor inconvenience (Calling the bank and notifying them so they can issue a new card and cancel the charges), but with a debit card it can totally screw up your checking account for weeks, plus you lose access to the card for local purchases while everything gets straightened out. Not a risk I want to take.

I just received my R3 a few days ago... I have a HUGE suggestion, and how I got mine.

Find a small camera store. In a town, and call them... even if you have to drive a few hours outside of wherever you live.

I said I wanted one, and they were able to get it in my hands in like a week and a half.

I was shocked, when I ordered it, I told them I just forgot about it because figured it wouldn't be in my hands for 6 months an they said, well since we are small we can get one in and not necessarily sell it right away because in smaller towns, more expensive cameras, stick on th shelves for longer

---Opps, rookie mistake, I originally posted my first-hand experience here, when I should have posted it elsewhere in the forum. My apologies. You can find my preliminary experiences and (first post) question to other Canon R3 users under the forum heading, "EOS R Series Camera Discussion RP, R, R5, R6"---

Confirm that you don't experience the back focus with the lens at f/2.8. If you do, it is likely a malfunctioning lens. The focus shift that is part of the optical design occurs only when you stop down, and generally only at macro distances. Your reference to back focused portraits makes me wonder if you simply have a bad copy of the RF 100L Macro.

Click to expand...

I confirm that I don't experience focus shift at f/2.8. And for the portrait remark take a look at the Dustin Abbot review when he talks of the picture he took of his cat...I experienced the same problem of focus shift at f/5.6.

Nemorino said:

I will buy one soon or later. I need the higher mag and like the SA control. Chris Frost mentioned the shift would be small at macro distance (5:40) and it won't be "terrible an issue" ( free quoted @7:20).

At the moment I use a Sigma 105 macro and the RF100 will be probably better.
If I would own a EF 100, I maybe won't buy one.

Click to expand...

Do yourself a favor and buy the EF lens! The focus shift is more severe than you think. I own both lenses and can assure you that it is a bad lens...

The Canon EOS R5C has been long-rumored around these parts, and it will finally be officially announced on January 19, 2022.

I myself have not found the heat issue ? Maybe its the colder climate

Click to expand...

I don't have it either, I just take stills and not at high speeds. However, overheating is easily reproducible if you push the camera to record high data rates to the CF Express card over a period of time. Just doing stills is not an issue, its high rate video that generates the heat faster than it can dissipate. If the camera is insulated, heat escapes much more slowly, so that may change .

kwanfs said:

I But I’m confused because people say the RF15-35 has wobble when it’s at 15, you have to zoom in a little bit to get rid if it. But the 24-70 already zoomed in more than 15.

Click to expand...

Presumably the issue is occurring at the wide end of the zoom range for that lens, not at some specific focal length(s).

Naïve question, is this only with video? I don’t notice anything odd with my R3 and RF 14-35/4, but I don’t shoot video on ILCs.

Thank You! This helped me a lot.
I just placed my order and I will get the lens on tuesday!

tjm1989 said:

[..]I guess I have two questions for you all. After all the recent firmware updates on the R5, how long do your R5 cameras last before overheating in 4K HQ? Can you still capture stills when they do overheat, or is the camera rendered useless until it cools down?[..]

Click to expand...

Still capture is completely unaffected by video (over)heating. During summer I tried to film dragonflies at 120fps (complete failure, not due to gear) and got the overheat warning, switching to stills let me do 20fps photos till I overheated myself and had to find some shade
