RF 24-105 f4-7.1 vs RF 24-70 f2.8 in daylight

It looks to me as if DXOmark may have stopped assessing camera sensors, which could be an issue in the future, although it is easy enough to test for yourself.
However, they have tested the R8 which uses the same sensor as the R6II, and at base iso 100 the camera is actually 66. So I would set 1/60th. If you do this you will find that the rule works for you. Remember to give back half or even a full stop if there are significant shadows depending upon how prevent they are and how important detail is in them to you. (This is why the rule works for evenly front lit subjects).
As the ISO climbs the difference between stated ISO and actual gets less. Link is to the DXOmark chart for the R8.
For people only using the camera meter the difference is irrelevant, but if you are using a handheld meter it is very important. (Or the sunny 16 rule !) This is why the latest handheld meters such as the Sekonic 858 can be custom profiled to exactly match your particular camera.

RF 24-105 f4-7.1 vs RF 24-70 f2.8 in daylight

Beware the Sunny 16 rule with digital cameras !
As has been correctly stated, the ‘rule’ is when the subject is lit frontally and evenly in full sunlight, from two hours after sunrise to two hours before, if your shutter speed is the ‘same’ as your iso then f/16 gives the correct exposure.
The problem with this rule and most digital cameras is that their stated iso is not the real iso. So to use the ‘sunny 16’ with a digital camera you have to know what, say 100 iso on your camera really is. This information is available at both dxomark and photonstophotos.
To use a Canon R6 as an example, the camera stating 100 is really 63.
So to use the sunny 16 rule when your R6 is set to 100 iso, on a full sunny front lit day set 1/60th, not 1/100 at f/16 and you’re exposure will be spot on.
On my 5DS the 100 iso setting is really 77.
Thanks for that update. I have the Canon R6ii. Do you know where on those websites I can find the iso data?

The Canon EOS R7 Mark II likely isn’t coming in 2026

I miss my glory days of canon crop. The XSI and t2i- which i still own - and battery still works - were just champions. The clarity of that xsi sensor, the colors of the t2i..those were the days.

After trips across the globe, My 7d fell apart, sensor wise. Canon could never fix (4 tries!!) and i said never again to large crop cameras after that.

RFS- not s chance. The r50v cheap build made me look elsewhere..and right to an s9 retired my m62 w/ evf & awesome smallrig cage, + 32mm sigma, 11-22, etc.

Small full frame is the play. + Sigma lenses..win.

Thanks. I found a handy chart that further explains it. It’s going to take me some time and practice to get handy at this.

To quote Roger Cicala, "I was, er, might have been wrong, ahem... less correct than I originally wrote." :)

I was underexposing by a stop to protect the highlights with plans to boost the mids and shadows in post while holding back the highlights. ;)

Yeah, that's it! That's the ticket. I was protecting the highlights! :devilish:

I seem to recall a rumor that the R7m2 was "out in the wild." If this was true, it might be the real world testing by photographers they respect didn't produce very good results. Maybe they need some time to improve it.
Or perhaps the R6 V was ‘out in the wild’ and assumptions were made about it being the R7II.

There's no criticism from me about the rumours, because they are just rumours, and until things are announced, you can't be sure. But it does just about confirm that I'll be leaving Canon RF, I will keep my EF system based around a 5Ds, because it will be useful for high resolution FF landscapes and macro. I got a m4/3 system, based around an OM-1 mkII because it does most of what an R7 mkII will do without quite the resolution, which is no big deal as my 7D was only 20mp.

The Canon EOS R6 V and RF 20-50mm f/4L IS USM PZ are Coming May 13

I hate to break the news to you, but none of the boomers are middle aged any longer. Those born in 1964 are turning 62 years old this year. All of the boomers will officially be "seniors" by the end of this year. In most places, they've been considered "seniors" since they turned 60 in 2024.
Damn u hit me where it hurts the most ;)

A bit off-topic, but hey, community life.

1) I meant in the slang context, as in somebody who seems rigid and oldschool crying about losing old stuff and having difficulties accepting new trends.
2) My country had a very different history and demographic graph, we had a boom in the 70s.

Cheers.

You would hope so -
Canon obviously have much more data than we do about what sells and what does not.
Similarly they will have survey and focus group data - but that's very subjective based on which audience and question you ask.

What no marketing department have is a view of how well the product that they did not launch would have done or how many people purchased an alternative because you had a gap in your lineup. Not many people call to say hey I bought something else or switched systems.

I really do hope that Canon come though with a worthy successor sooner rather than later.
Sure, it's not an exact science by any means. But if anyone in the industry has a handle on it, the perennial market leader should. I'm quite suspicious of a lot of forum posts that boil down to trying to make personal disappointment into sometging bigger and more objective (not aimed at anyone in particular).

Anyhow, a lot of people have assumed this represents a postponement but if it boils down to CR misreading the runes then maybe it was never planned to come this soon.

The Canon EOS R6 V and RF 20-50mm f/4L IS USM PZ are Coming May 13

I may be wrong but the size and weight difference i expect to see would be quite small to an R6, because of same battery, IBIS, cooling vents....
Ok, you'd lose the EVF bulge...
But for Photo i really want a VF, optical or otherwise, i tried multiple cameras without it, i prefer a Viewfinder.

Perhaps an R10 or R7 (1000 € on sale if you are patient) could also be a nice small camera with the plus of giving all your lenses a different field of view.
And the R7 even has the same battery as your R5II, so no problem there.

Well, I absolutely love the size and look/format of the R50V, I almost bought one. The only reason I didn't is the aps-c. I hate aps-c :) I don't think the different field of view is an advantage, especially since it's not the angle but a crop. Very bad at wide angles.
I owned an R7 and while I loved the handling (somehow for me it was even more intuitive than the R5m2) I was pretty dissatisfied with it's overall performance, especially AF. The R5 was a salvation after the R7.
And to top all that, I do a fair amount of wildlife and I'm not willing to use aps-c even for that. That's how much I hate aps-c. You just feel it everywhere. The EVF size, the noise and sharpness, etc...

The R10 and alike, while they are definitely small, I believe the compact format (shape and size both matter) can better it. An R50V+28/2.8p is almost a pocket camera. Even an R100 is far from it.

As for not having an EVF...will see....I shoot a lot with my iphone and I don't miss it. I know, the iphone display is worlds better than anything any camera will ever have...time will tell.

The Canon EOS R7 Mark II likely isn’t coming in 2026

I have been waiting for the R7MKii to replace my 90D. I could not see going to the R7 as it was not much of an upgrade for me and I do have a R5 as well as a Nikon Z6. For my wildlife photography (the majority of my photography) I use my R5 with a RF100-500 and RF200-800 along with my 90D with my EF 800 f/5.6. I was hoping for the R7 MKII to upgrade this. Since the delays in the R7 MKII I have been looking at the OM System OM-1 MKII for more range and better performance than my 90D. Looks like I will be adding the OM-1MKII to my camera systems and keeping the 90D for a while. I could even go to the OM-5 MKII and have an upgrade over my 90D and better performance over the R7. Canons marketing strategies has lost them another customer and longtime Canon user. Also, since I use the Nikon for street and travel photography, I can get rid of that and just use the OM System to cover all my photo needs.
I think your situation is similar to the dilemma that many of us are facing.
The R5mkii convinced me that Canon mirror-less was finally ready to replace the DSLR, specifically eliminating rolling shutter with fully electronic shutter to the point that its a none issue. While bringing many great performance and feature updates.
I was really hoping for a return to the 7DmkII approach, essentially an R5mkii with a cropped sensor, as the 7Dmkii was to the 5Dmkiii, which was the perfect pairing. Having shot with the R5mkii the 7Dii now feel rather "agricultural" and dated.

The current R7 is just not there features and performance, wise and especially with the body layout. Otherwise I'd have picked on up as an interim step.
The R6mkIII does not have the reach and also does not resolve the rolling shutter issue.

The ideal solution that would keep me firmly in the Canon ecosystem is an R7mkii with an RF100-500 (assuming of course that it lived up the the rumored specs). While the loan RF100-500 is a fantastic lens on the R5ii it's still not got the reach of a proper crop body. Where as crop mode drops the resolution just a little to far. I wonder if Canon take into consideration that lost lens sales opportunities along side the body decision. In my case the EF-100-400 would have been replaced with an RF100-500 along with the new body.

I guess both the 7Dii and EF100-400 are coming off sale now.

I was disappointed that the R7mkii seemed to be on the cards for late 2025 and then into 2026 - a further delay starts to rule Canon out for my crop needs for Aviation and Wildlife.

The Canon EOS R7 Mark II likely isn’t coming in 2026

This is bracing. I really am looking forward to the R7II.

My problem now is, how precise is this new prediction of the R7II not coming in 2026?
A week ago it was 99% coming in may...

I looked at these rumors in the past like "where there's smoke, there's fire"...
Apparently, that was my bad, and i overestimated the quality of information provided.

This will change how and if i look at rumors in the future.
I really like the idea of getting information ahead of time,
but i rather have no information than wrong information.

One way or another we will see what the future brings...

You are steeling my thunder! When I read this post I most probably switch to ON-1ii as well with their Zuiko 100-400 lens. 120 fps, stacked sensor, the whole lot. Unfortunately 400 grams heavier but IP55 sealed!
Still I wait till end of June, to see what happens if the patent embargo is lifted.

Why were they selling off the R7 I then? And interestingly enough, its price fell down to 1050 EUR just a couple of weeks ago when it rose to 1150. Seems almost as if they changed their mind.
Its seasonal: during winter you can buy it body only for under 1000€ in France. Prices rise when good weather comes.

Quite the disappointment.
I was hoping the release of the R7MkII would push down the prices of the 7D2 so that a particularly good deal could be had on one.
I don't really understand what you are hoping for. The 7D2 is a 12 year old camera that is already very cheap. Excellent used copies can be had for £400, probably even less.

A bit disappointing to hear the R7 II could get released next year, but that's how rumors go. In my opinion some of the R7 II rumors sounded to good to be true, as if it were on the same level as an R5 II with an APS-C sensor. I thought the R7 would have needed the update first over the R8, the R8 already seems pretty solid for it's market but it would be nice if the R8 II got the joystick and the bigger battery which I don't think it will on the 8 series. I also hope the R8 II will get a normal version and not just the retro version.

Guys, I understand that everybody is disappointed and blame Canon rumors now. But, as with all things also this is only a rumour. In the entertainment industry they say "important that they talk about you, being negative or positive doesn't matter". Now EVERYBODY is talking about the R7II not coming. Let's wait and see ;)
