Leaked: Canon EOS M50 Image & Specifications

Dumb question.

Why call it CR3?
Canon could have made all the changes and still could have called it CR2. What am I missing?

If they're making a large change to the structure of the file format itself, it might warrant a bump in "major version" instead of just releasing a new version of CR2. There might be enough accumulated cruft and backwards compatible hacks that they want to fix even though AFAICS CR2 is a pretty flexible file format.

Or - some humorous answer - they may want to state that it is certainly (CR3) Canon Raw instead of .. probably (CR2) Canon Raw (Sorry I could not resist!) ;D ;D ;D

According to DXOmark's data, there is an absolutely huge difference between the 200D and Canon M3.
When you set the camera to ISO 3200, the actual ISO on the 200D is only 2125! Whilst the actual ISO on the M3 is close-to-ideal ISO 3133. This is nearly a quite massive 50% difference in sensitivity (3133 is 47.4% more than 2125).
7D mark II gives 2458 ISO at the same setting.

This has real-world implications for shooting. If you were using a certain ISO and shutter speed on the Canon M3, you can no longer use it on the 7D mark II or 200D... you would possibly need to bump the ISO up one stop to get a proper exposure.

We are not doing an apples to apples comparison in dynamic range tests if we set both cameras to 'ISO 3200' in the settings.

We could arbitrarily slap the 'ISO 3200' label onto a camera with a real ISO 100 setting, and it would beat all other currently manufactured cameras.

This is why comparisons like this give a clearer picture than the link you offered, which is clearly labelled "Photographic Dynamic Range versus ISO Setting'... unfortunately there is a discrepancy between "ISO setting" and "actual ISO sensitivity", a huge one.

https://ibb.co/n0zLQx

If you set the 200D and the M3 to 3200iso there is 0.15 stop of a difference between the DR. You can follow test results down rabbit holes or just make simple comparisons, I choose to do the later.

In a real world scenario you might find the 200D might need more over exposure to get an optimal exposure but that doesn’t alter the fact that as a baseline performance there is 0.15 stop difference in DR between the two at 3200iso, 5.54 stops to 5.69 stops. And the point of that is that at these two mathematically derived figures the component of noise is equivalent.

If CR is correct about the price (around current M6 prices), it will decimate all previous body sales. M5/M6 (maybe even m100) sales would be almost nil going forward and it would give Sony/Fuji some very good competition despite the lack of a full native lens library.

This would, of course, depends on if Canon severely crippled the M50 somehow. If so, that would be the worst mistake.

I would be interested for an alternative to Sony A6500/Lumix Gh5 for cheap gimbal work.
But I'm not sure if I'm ready to invest in something that doesn't have 4K 60p or at least 120fps FHD with sound.
I'm sure Canon will still hold back it's newest technology and will cripple features.
But even so... it proves to be very stable and reliable. I'm looking forward on Canon gear because I want something that I can work with confidence and it would be very painful to sell all my Canon branded equipment.
So... Canon, I could use my money on other brands or on yours. What you say?

In the beggining, CRW:
https://sno.phy.queensu.ca/~phil/exiftool/canon_raw.html

Today, CR2:
http://lclevy.free.fr/cr2/#intro

Both TIFF format but different.

Why CR3? Who know.
Special for Dual Pixel? If yes, 5D Mark IV get CR3 in firmware?

Also, it states that the C-Raw files are 40 percent smaller than the CR3 files and about the same size as the old RAW files....

This answer. CR3 because compression change.

Canon follow Apple, replace JPEG by HEIF in CR3?

Magic Lantern show JPEG for RAW, don't understand?

why would it? I wouldn't trade my M5 for this.

this camera's song and dance will be 4K video and ergonomics to match 4K video, not stills. can sort of tell that from the one picture. No mFn button anymore, the record is there.

Odds are canon tweaked this to be exactly for the needs of vlogging.

it's not "crippled" it is just a camera body that canon has tweaked to be best served for it's purpose.

compression alone wouldn't do it, from what i recall from the makernotes, compression is an option there.

I suspect the different file format is because of the inclusion of DLO information which would be drastically different output if it was in non-destructive information.

Certainly it will be the first Canon with their new sensor generation.
Remember the heap of radio related registrations for rebel cameras?

I bet that Canon is switching their entire sensor platform to a new
technology, starting with all entry and middle class cameras for
Photokina 2018, and likely the big guns to follow for Photokina 2019,
which is just half a year later in may 2019.

Some might convert to mirrorless at the same time, some might
remain mirror slappers.

Nevertheless, this is a milestone.

The M50 might not be the most exciting camera ever, but it
marks the switch to a complete new sensor generation.

DIGIC 8 for 4K in mirrorless.
DIGIC 8 have H.265 in chip? Need for cool chip process fast video.

HEIF use HEVC (H.265). CR3 for DIGIC 8 newer only.

https://en.wikipedia.org/wiki/High_Efficiency_Image_File_Format

HEIF 50% smaller on JPEG:
https://www.tenorshare.com/heic-converter/heif-vs-jpeg-everything-you-need-to-know.html

JPEG encoding used for raw. Change to HEIF. Maybe only 40% on raw.

But why Canon say "C-RAW"/"in-camera raw"?

Read Wikipedia:
"Additionally, HEIF introduces a framework for other non-destructive editing operations which can be specified by external specifications."

But all is guess :)

Not at all. Introducing a new sensor platform doesn't necessarily mean
the found the holy grail of sensors. They will be somewhat better than
what we have (in Canon cameras) today, but expect no miracles.

Isn't this inevitable in threads such as this!! ;D

Yes, and then when Canon doesn't have all the specs that people here are wishing for and speculating about, they will say stupid canon instead of Stupid ME!

For heaven's sake - we don't even know that this is a new sensor! Maybe someone types "24.1" instead of "24.2" and everyone goes berserk.
