If you are focused ONLY on video, you might have an argument, if you want a hybrid, 12mp is so outdated it's not even worth discussing.

Aha? So which of the Sony 45+ MPix sensor cameras oriented towards still photographers outside extreme low light have you seen, that totally eclipse the R5 in dynamic range? History so far seems to tell me, that special low light cam seems to be tied to tiny MPix. You seem to mistake the R5 as such a model?

Also I think you may have to be careful about those range stops the companies spew out and head over to photonstophotos.net etc. But frankly, it wouldn't exactly be a wonder, if it wasn't a bit better even after proper reviews. Istill consider the R5 far ahead for what I like to do ;) It seems the new Cannon arrival seems to cause a lot of need for defensive strutting in other camps? What's that about?

What's it about? It's about starting a brand war thread for no apparent reason, it seems. Some are expert at it.

just out of curiosity what was the dynamic range that Canon - they themselves listed for the R5 ?

I looked at their detailed specs - I could not find it

So the 11 stops value on your headline is just a random number without any actual source? More than a bit clickbait-like...

You are almost certainly comparing "apples to oranges"

I have not tested either camera yet but for Engineering Dynamic Range (EDR) for the Canon EOS 1DX Mark III I have 13.7 stops and for the Sony ILCE-A7SM2 I have 14.0 stops. That is not a dramatic difference.

What do you mean the "other camps"? Is this the Nikon forum?

When a company starts paying me i'il say whatever they want about their products, but until then i will use any cameras i see fit.

I'm sure nobody here has any bias towards any camera brand in particular, especially since that would be objectively stupid.

had I posted this iso 1000 image and said I took it with a A9 would someone have said

"I call BS - that looks like a low res 12 mp image to me "

When images are scaled to 374x560 pixels, or about 0,2 megapixels that's a pretty effective equaliser. That's less resolution than good old VGA monitors from late 80's / early 90's allowed.

An Instagram sized photo to prove something? You can use any modern high end smartphone for that shot.

It'd not though. It's a 12mp image.

Have you seen this as a result of an independent test, or are you just quoting Sony marketing material?

You have to ask yourself this question :

Am I more likely to take video of family and vacation sites or print giant posters for my walls ?

More likely to post wind ups with no basis in fact like this one, at a guess.

Right, the original size link :) Anyway, still not sure what it is trying to prove? That a 12 Mpix image looks like a 12 Mpix image? Noone said a modern 12 Mpix camera takes a bad looking 12 Mpix shot?

I forgot that for some unfathomable design reason the mobile version of the site does not offer a link to the original image. Looking at the desktop site now, there's indeed a full-size image available.

So, apologies for undeserved criticism as far as that is concerned!

Also, I'm not sure the difference between a low Res and a high Res 12mp image..

Give your definition of DR, and where the figures come from. The R5 has 1.26 14-bit DN of noise in the masked pixels of the Studio Comparison Tool RAW at ISO 100. At 45MP, that is about 0.53DN, normalized to 8MP. Divide the clipping point of 15,871 (after subtracting black at 512), and you get a ratio of clipping to read noise floor of 29:945:1, or 14.87 stops of 8MP-normalized DR (engineering definition; PDR takes in photon noise and will be lower, as it does with all cameras).

Not I; I see a lot of NR, and recognize the fact that the default magnification of a 12MP image is low, even at 100%, compared to a 45MP camera. I have no doubt that the A7s3 has less visible noise at ISO 102,400, but at ISO 1000, we are looking at mostly photon noise in any modern FF camera, and that does not vary from camera to camera like read noise does, and photon noise character is a consistent property of the universe, and not of the camera model, but read noise character can vary quite a bit, even at the same measured standard deviation. The R5, like a few of Canons recent cameras, have fairly random noise character, by current standards.

Consider the fact, however, that many people will just look at the image as seen embedded in the post, and draw conclusions about noise and sharpness.

We don't need you coming in here with your scientifically sound analysis and data, debunking any sensationalist posts!
