I have how had a massive tutorial session with ChatGPT to answer this. The conclusion is: "Canon DGO is restricted to Cine EOS because it is architecturally incompatible with high-speed, high-resolution stills capture. It is not a feature being withheld; it is a feature whose physics conflict directly with the performance envelope stills cameras must satisfy."

Higher dynamic range is possible without DGO, it needs a fast sensor to read out the low and high gain modes simultaneously. The partially stacked sensors in the Sony A7 V and Panasonic Lumix S1II can do this.
According to DPReview:
“Unlike existing dual conversion gain sensors, which could use either a low gain (high capacity) setting for low ISO and a high gain (lower noise but lower capacity) mode for high ISOs, the new sensors can do both, simultaneously. So you can capture the full capacity of the low gain mode but combine the cleaner shadow data of the high gain mode.
This process, which we suspect involves sample-and-hold capability in the more complex readout circuitry, takes longer than reading out just a single mode. As a result, it can only be conducted in the mechanical shutter modes, where the physical shutter stops any more light accumulating, giving you as much time as you need to read the sensor.”

Well done thanks for sharing!

yep it was hot chocolate

Thank you - when I saw the view from the plane's window I knew I had to wip out the camera

Sorry, i maybe missed it in review, but was the issue with IBIS wobble on wide angle fixed? Or what was meant is that it is only fixable by digital IS, which is not possible to use without IBIS? Is it the same on R5?

Click to expand...

Unfortunately there is still a wobble problem. GyroFlow is a good 3rd party software solution, but it needs the gyro data that only the modern cameras have (R6 III and C50). Here's a good video showing footage without and with GyroFlow: https://www.youtube.com/watch?v=-uRclDI4fmE&t=51s

Very nice close ups. Im especially like the second one.

These are with the Sigma 105mm macro. BTW what I wrote above for the butterfly is not correct: they are taken with Tamron SP 90mm macro: I used for them my daughters camera and didn't notice it's with "my" macro-lens !

Very nice close ups. Im especially like the second one.

I really like the dark background. Nicely done, Noreaster.

I’ve only looked on my phone at the picture on which you didn’t like the highlights on the faces; assuming you shoot in raw have you had a look at the raw file with no tonal response applied ? If so you might be surprised at where the highlights actually sit, and it’s the applied tonal curve in the highlights that you don’t like. Just a thought !

I had indeed try to edit it and ended up not liking the results and left the jpeg as is. This is screen grab from ACR flat and other sliders just to give an hint of the data available. It's not only that there are unrecoverable patches of white, but even the data that is recoverable is structured in a way that doesn't make it very useful for me.

At the end of it multiple people liked the photo as is, for the big burn of light as well. It's just me who would prefer to have full readability always. But I do think that Canon is feeling the competition from Sony and will probably do something about it in the future.

And presumably the processing power requirements would increase proportionally on higher MP sensors - meaning that DGO would be more appropriately used on lower MP sensors? I seem to recall that even on the Canon C cameras, DGO was only available at lower FPS - ie there was a limit even on a 35mm crop.

Click to expand...

Yes. Low pixel count is needed with lower fps. Also rolling shutter artefacts aren’t as disturbing in video.

This is because the camera needs to read teach pixel twice - at low and high gain - and then blend them into a single image?

Click to expand...

Yes, apparently it is a time and power consuming process. Anyway, I learned a bit about noise at very low photon flux. There is a changeover from photon shot noise when decreasing below about 10 photons per pixel exposure to electronic shot noise. The DGO lowers the photon floor to down to 1 photon when electron shot noise in the circuit takes over.

AlanF said:

to make it work you would need to give up:

• burst rate,
• readout speed,
• power envelope,
• thermal envelope,
• AF responsiveness,
• electronic shutter usability.

That is a commercial non-starter for stills cameras.

Winter is not too exciting

I do hope that when Canon finally releases the RF300-600mm lens it has a built-in 1.4 teleconverter. This would make it ideal for bird and wildlife photography.
