Canon EOS R5 Specifications

5D IV was and still is a very good camera!
Cant agree more :-)
It got beautiful colors and a nice look right out of the box. The handling, ergonomics and menu is perfect. Its robust and reliable, got dual card slots and all recent features you need for a professional workflow. The Dynamic Range was NEVER an issue for me - I cant remember any picture where I said "oh shit, I cant use it because of missing Dynamic range". It got a reliable AF in both viewfinder and LV. It got enough resolution for most situations.
The 4k mode is not usable, which was a downer. The FPS could be a bit higher. But other than that I dont see anything wrong with it. I bought it a few month after release and used it as my main camera for most professional photography work I did since than. (Only recently I used the Sony A7R IV for some product and travel photograpy. I prefer it because of the higher megapixel count for product shots, though I dont like the colors that much)
The 5D IV was and still is a good camera for 95% of a photographers professional work.

I'm hoping they announce simultaneously as you say, or at least disclose whether a 75/80 MP is coming soon or not at the time of the 45MP body announcement.

The rumoured specs are spectacular but I'm concerned about the DR. I really hope they improve DR in this 45Mp model and keep it at least on par with 5DIV in the 80Mp one.

I know the initial rumor on the 75MP one included the line "sensor focused on the dynamic range” . Whether that would come true and make it down to the 45MP...dunno.

Who the hell cares about video? I don't! Please Canon make a stills camera that has no video features whatsoever. And if you don't care about vid, this camera is a yawner. If it has super weather sealing and if it has super dynamic range and if the viewfinder is the best available, then we have something. Otherwise it's just another Canon Chevy.

I guess if the highest throughout of any ILC like ever, a 15mp bump, a whole host of AF improvements, access to the best mount in photography, 5 stops of stabilization on all your current glass, etc is a yawner then congrats on not needing to drop $4K on a new camera.

I am confident that the rest of the things you mentioned will be improvements over the 5D series as well.

I just cannot fathom that Canon would backslide on DR. The 5D4 isn’t really class leading, but it did put a nail in the coffin of the argument that canon “can’t” offer a competitive sensor.

How many of you came here and refresh the site 256 times in the last 24 hours!! OMG! :D Clearly we needed this from Canon! We got hyped with the 1dx mkIII and now this! There were 2 years waiting but i think it will be worth it! Can´t wait for more specs and confirmations!

Exactly. But if Canon specifically promises high DR, I'm happy to believe and I'll even preorder the camera.

Yep. But literally all full frame models from Canon after 5DIV were worse than 5DIV in terms of DR. EOS R is slightly worse for some reason although it's the same sensor. The difference may be negligible but it's consistent across different sources.

Ah, we haven't seen 1DXIII measurements yet. Maybe it'll do better.

You don't decrease the read noise by raising ISO at all, that's the point. You can raise ISO after ADC by multiplying the digital output, or before ADC by analog amplification. Both ways, the reading has already happened so you can't reduce the read noise by raising ISO.

I showed you actual data with reduced read noise at high ISO, and told you that raising ISO reduces read noise. It does. This is because adding analog gain increases the signal while leaving the electrical noise the same, thus reducing the noise relative to the signal. Since read noise is measured in e- (captured electrons), the read noise is reduced when you increase ISO.

Moreover, after raising of ISO, the resulting value has both signal and noise amplified. That's why high-ISO images are literally noisier.

You literally don't know what you're talking about. High ISO images shot at the same exposure are less noisy than low ISO images. The reason you have this mistaken impression is that we usually use higher ISO when we want to reduce exposure (increase shutter speed or increase f-stop), and that means less light is captured. This also means less noise (noise = sqrt(signal)) but a lower signal-to-noise ratio (SNR = sqrt(captured photons)). Once you make the final image brightness the same, the lower signal-to-noise ratio means more visible noise, but that's mostly from shot noise (photon counting noise), not read noise.

You willing to pay more for a camera without video? Because that's what you'd have to do.

Nah, I've been over at Fujirumors and those cats are freaking about the X100V. Fixed Lens Frenzy I tell you.



What's been going on here?

This is because adding analog gain increases the signal while leaving the electrical noise the same, thus reducing the noise relative to the signal. Since read noise is measured in e- (captured electrons), the read noise is reduced when you increase ISO.

So you're just mixing up SNR and noise. You're saying that raising ISO decreases noise but then stating that noise stays the same. SNR is a ratio while the noise is a value in the ratio.

You literally don't know what you're talking about. High ISO images shot at the same exposure are less noisy than low ISO images.
errrm... if all settings are the same but ISO is lower, the image is just darker. And no, it's not less noisy. With Canon sensors, they normally do analog amplification up to 4-8x which is ISO 400-800. The rest is digital amplification which in fact is just multiplication. So images at ISO 1600 and ISO 3200 will be roughly the same after you add +1 stop to the ISO1600 image in Lightroom.
Up to ISO 800 it's better to set ISO in camera so that it does analog amplification as it's more accurate.

This also means less noise (noise = sqrt(signal)) but a lower signal-to-noise ratio (SNR = sqrt(captured photons))

Can you show me a paper that has these formulas? noise equals to the square root of signal?? Also SNR by definition is (signal / noise) and nothing else.

This new post on the EOS R5 ( the mirrorless 5D ) already has more comments by far than any post going back to at least early last year ( I finally gave up looking back). Canon....make this the camera we have obviously been yearning for. Don't F it it up with the Canon Cripple Hammer

A LOT of people. Like, everyone who bought an a7s, and GH4 and 5, an now an SH1, and Fuji Xt series, an so on. Most of what I do is stills but video is growing and there is a big market out there for video focused cameras that aren't big body $10K machines

Why are you still feeding that troll?
