Canon EOS R1 & Canon EOS R5 Mark II announcement coming July 17

Yes, I've done the same, but with white paint. That did help a bit, but I still get so frustrated not to be able to put the rear cap on without looking, like I've done for decades with EF lenses. It's insane that someone approved this design, makes me wonder how well they tested it in the field...

I've resorted to placing the lenses upright and correctly 'clocked' in the cupboard (no white primes here!) to make lens changes faster and as a bonus it improves the odds of getting the cap correct.

In the field that all goes out the window and I have to pay attention to the red dot.

Based on a DPR post, it's possible to physically modify RF rear caps so they work like EF caps. Should be pretty straightforward with a Dremel, but I have not tried it yet.

Since you are one of the first ones I heard of that actually used that feature, how is your experience? Do you wear glasses? Does it work outside where the lighting and sourroundings changes all the time? Because I heard some people saying it needs a re-calibration whenever the environment changes just a little.

I do wear glasses (-7.00 on each eye, so fairly thick ones) and have brown irises.

I calibrate the ECAF before each shoot since the lighting environment can be quite different (I shoot a lot of theater) but that takes 30 seconds per camera and is just part of the pre-shoot routine for me, like making sure cards are formatted and the clock is synced across the cameras.

Thanks for sharing, neuro.
My initial thought:
Meh! If it's that easy, I want that from Canon.
Make a new injection mold negative! Come on Canon!

That would require Canon to admit (to themselves) that they made a mistake. I won't hold my breath.

Do you use the feature on an R3? Because I though the same way after the first announcement, but after going through the scarse amount of reviews I could find, my initial exitement was gone quite fast, especially because I also wear glasses where the Eye-AF is even worse.


Yes, that's what is rumored for the R1. However, the rumors for the R5 II explicitly stated, that it will inherit the version from the R3.

I've tested a rental for a long weekend, and I loved the Eye-Control AF. So much that I'll never even consider buying my main camera without this feature. I'm presently impatiently waiting to place an order for an R5 II WITH eye-control AF.
If you do not like it, provided you've really tested it and don't rely on internet comments, that's ok. But express a personal opinion, and don't defend silly generalizations like Cyborx' "a feature that R3 users shut off because it sucks".
Because this is simply untrue, and a typical comment by a troll...

Twas just wishful thinking. I know, they won't.

If it's that easy I'm surprised no third party has offered some simple replacements. I imagine there'd be a good sized market, as I'd order a bunch, as would just about everyone I know that uses RF. The OEM caps are stupid.

There are 3D printer templates available online. I'd order them, too. As @Del Paso pointed out earlier, there's a German company that sells them (screaming red and with their logo), but they only ship within the EU.

Out of curiosity I started searching online, and apparently there are a few out there like: https://www.bhphotovideo.com/c/prod..._rear_eosr_red_rear_lens_cap_for.html/reviews

Only thing holding me back is the review saying it fits a little loose.

Don't see anything suggesting that one goes on in all three orientations, from the product image it looks just like a Canon RF cap (meaning you have to line it up just right).

I think you underestimate the importance of cars in many people's lives.
Your car defines who you are (silly,isn't it?)
Fatties buy sports cars to feel dynanic and young, a bigger car "proves" you are important. With a car, you buy a personality (silly, isn't it?).
I've dealt with so many "important" customers buying "premium" cars as a testimony of their "importance" to take all this circus seriously.
And, during all that time, my wife and me were driving non-premium Renaults, to our fullest satisfaction. No one knew, apart from my collegues ans boss, and they didn't care at all...( My boss had a Lamborghini Diablo!).

I'm the most insignificant person on CR, driving a Toyota Prius.

On closer inspection, you're right. Bummer.

"8K 60p with cavaets" maybe it simply means it won't support dual exposure, aka extended dynamic range, like all the other modes.

 

[DSB]

Yes, there are aftermarket caps that work better. However, since Canon has a proven track record of being able to produce a simple, effective and user-friendly rear cap design, I think they should address the issue and update the design.

I think I saw someone claim it's possible to DIY the current RF caps to work similarly to the EF system by cutting out some of the pieces of plastic from inside. Wish I bookmarked that diagram...

Except your example graph does not show all performance variables. Nor does your example include all of the other circuit factors contributing to the noise in the R3. HEAT. The R5 is a larger body and although gets cherry red hot with heat buildup, Canon throttled back other performance variables to mittigate heat. Signal + NOISE = Dynamic Range. The R5II will have a far better heat dissipation circuit and a new vent system. None of which exist in the R3. The R8 has far less performance variables, less heat and therefore less noise. The R5II will run circles around the R8. More performance variables.

you people are really discussing the most pointless, useless topic when it comes to how you will end up recovering any highlights on any of todays new cameras. If I gave you 3 files from the cameras you mention as a double blind test, your dumb human senses wouldn't be able to tell which has more or less dynamic range and you'd struggle to tell me which file is which camera. Get out there and shoot.

It's good advice and all, but it's a gear rumor forum so these discussions crop up when there are gear rumors. I don't think anyone here is like "oh man this thread about lens caps* is gonna make me a better photographer." It's FUN to talk about/argue about/speculate about gear.

*ironically this is the biggest QoL issue I have with my R5. I could swap lens caps on EF lenses blindfolded.

Which proves a split (hybrid) personality!
From now on, I'll only answer posts by premium car owners, sorry!
I won't waste my precious time with Japanese 4 cylinder hybrid car owners.

Who is running that dept?

The same person who nixed including lens hoods with non-L lenses.

One thing that I absolutely despise about the RF mount is the rear cap design. It is so frustrating to use and you can only mount it correctly one single way. EF rear caps were so much better, they had 3 different angles you could pop them on. Even 4 years later, I still battle with RF rear caps.

If you're not afraid of a doing a little surgery with an XActo knife, you can try this mod:

RF rear lens cap problem solved

I have hated how the rear caps work on RF lenses. While the old EF caps could easily be put on a lens without looking, like when you are using a shoulder bag, the RF cap needs to be positioned one particular way for it to fit. I searched for a solution, thinking that some company must have...

I did it to a couple of Amazon rear caps and it works great!

EDIT: Same thing that @neuroanatomist posted in post 242, just different pics.
