Canon announces development of the EOS R5 full-frame mirrorless camera

[slclick]

Hi Mike. So what is the latest on Sonyalpha? Are Sony now looking to exit camera business? Has it been announced yet or they waiting for the Canon RS to be announced first?
a garbage truck dumped a box of used Sony mirrorless cameras on my nature strip last night. Thought about calling Salvos and ask them to collect.

The poor writing, including numerous typos combined with incredibly small font sizes is an instant turnoff. Can't read that site to save my life.

From a build perspective, I think it's obvious by reputation and (I guess) a higher published shutter life as some proxy metric for toughness and durability.

But surely that reputation is earned. War correspondents and arctic tundra wildlifers generally are not toting M5s.

But I defer to the actual 1-series folks here. I do not own one.

As the classic saying goes: You can use it to club someone to death and still be able to take a picture of the body afterwards.

In this thread alone, I've heard comments that the R5 has to punch its weight against both the A9 and the A7RIV.

That seems nuts. What if it is intended for neither market segment? An R1 is coming, and we presume a super high detail RF body is coming as well.

Perhaps the R5 is just the new 5D and it just needs to hold its own versus the A7III / upcoming A7IV.

Yes!...and for a similar price, too!

The hood on the MP-E (it exists, google it, it's awesome!) is mainly there to keep the flash out of the front element.

Wow! I learned something today.

 

[AEWest]

I really hope that Canon will introduce in a near future an APS-C "R7" to replace my old 7D mk2 for wildlife photography. Also the new RF 100-500mm interest me.

I strongly doubt it will happen. With the rapidly shrinking ILC market, making yet another line of lenses makes little sense. Every camera company has to consolidate where it can.

EF-S mount was born in a much different market when FF sensors were very expensive to fabricate. So it made sense to create a more affordable line in a time where digital camera sales were rapidly expanding.

If I understand correctly, Richard is referring to the fact that the performance of the A/D converters is exponential in bit depth (which is to say, linear in number of discrete values). So converting a single analog reading to a 12-bit digital value is four times faster than to a 14-bit value.

It's definitely not linear to the number of discrete values, some of ADCs work in parallel so don't depend on the number of bits at all, some may be linear to the number of bits (which is log2 to the number of discrete values).

The bit depth per pixel affects the total amount of bits to transfer from the sensor after ADC, but that's obviously linear to the number of bits. I'm not qualified to do the exact calculations, but going from 14 bits down to 12 bits should give you ~14% less of data to process. It actually gets more complicated as the CPU processes the data in 8, 16, 32 bit chunks, but DIGIC is said to be optimised to process 14-bit sensor data, that is it may have special instructions to pack/unpack 14-bit chunks faster.

Anyway the point is, a 4x performance boost when going from 14 to 12 bits is probably greatly exaggerated.

What's the resolution .... ???

---

I can already tell you what the resolution will be for STILLS PHOTOS when Canon says the R5 can capture 8K video!

Unfortunately they don't tell you whether the video capture is DCI 8K (8192 by 4320 pixels) or UHDTV capture (7680 by 4320 pixels)

1) if it's DCI 8K then the STILL PHOTO CMOS sensor resolution WILL BE 8192x5455 or 44,687,360 total pixels (44.68 megapixels)

2) if it's UHDTV 8K then the STILL PHOTO CMOS sensor resolution WILL BE 7680x5120 or 39,321,600 total pixels (39.32 megapixels)

This means the camera CAN BE 44.68 megapixels (the most likely resolution!) OR it can be 39.32 megapixels.

This is because Canon ALWAYS does a 3:2 aspect ratio for it's still photo camera sensors AND since I HAPPEN TO KNOW A LOT OF MATH and that DCI 8K is ALWAYS 8192 by 4320, you can simply use 8192 as the starting base for calculating the VERTICAL RESOLUTION which SHOULD BE 8192x5455 pixels.

In many cases, it might be MORE because Canon has to normally ADD extra pixels outside of the sensing area for sensor calibration purposes, so it MIGHT be slightly more when it gets introduced. (i.e. but no more than 120 extra pixels on the horizontal and vertical)

Hmmm, after reading all that the biggest surprise was you didn't use the term 'Maths' because I always assumed you were British. Like the R5 actually being an action body, much to my surprise, chock that up to another error by me today, that makes 3.

 

[Kit.]

It's definitely not linear to the number of discrete values,

A ramp-compare ADC definitely is.

 

[BeenThere]

Wouldn't that be for getting full sensor 4K out of a 40MP sensor, rather than the other way around?

My poor attempt at humor.

 

[joestopper]

there's absolutely no way they are doing it in house. They never have.

TI as far as processors were simply using ARM - why the bump up? not sure, maybe they changed from TI and went to samsung or something.. who knows really .. probably not that important. However no, they aren't using AMD or something - some derivitive of ARM most likely - they have to be low power processors because of heat management. They could still even be with TI. who knows.

but anyways, can't focus on just the processor - there have been massive throughput gains on the last sensor generation starting with the 32.5MP.

The DIGIC X would be moot if those changes did not occur.

Fully agree. Its not the processor, its mainly the sensor read out bandwith.

I really hope that Canon will introduce in a near future an APS-C "R7" to replace my old 7D mk2 for wildlife photography. Also the new RF 100-500mm interest me.

Or maybe the R5 will be settable to FF, 1.3X crop or 1.6X crop. The 5Ds can be set to those, although it doesn't do 12 FPS. Also the R5 will probably cost a lot more than what you want. I have a 100-400 EF, 300 f/2.8 EF and Sigma 150-600 S, so the 100-500 doesn't interest me at all.

 

[joestopper]

Am I alone in hoping it has mismatching card slots? I seriously don't need memory cards to bankrupt me when also funding a new body and L plate. I bet if I shot video I would think differently but with stills, I am good with one of each.

Agreed. For those of us who mainly shoot stills, two CFExpress are overkill.

 

[davo]

The R5 is nicer looking than the 5D.

 

[PureClassA]

Agreed. For those of us who mainly shoot stills, two CFExpress are overkill.

I'm pretty sure the 5D cameras all had multi form factor card slots. Like CF and SD (one each). I'm willing to bet my lunch this will be the same. You'll get 1 CFExpress and 1 SD

 

[.jan]

Canon did say "up to approximately 12 FPS when using the mechanical shutter ".... that leaves it open to all sorts of caveats

It's always been up to depending on whether you chose focus priority or not.

 

[.jan]

What "app" are you talking about?

Canon CameraConnect.

The 5D and Mark II have 1CF slot. The III and IV have a SD slot for mysterious reasons that serves as the backup card fo some. If they go for two different slots it would make more sense to offer a CF+CFE combo for people upgrading, or just dump legacy completely and go all in on dual CFE.

 

[Quarkcharmed]

A ramp-compare ADC definitely is.

Ok, if it's used in Canon sensors, I could be wrong. However the AD conversion itself is only a part of the processing and the total amount of data to transfer/process after ADC is only reduced by 14%. The total win isn't going to be 4x.

Actually, --- I AM CANADIAN ---- !!!!

So we use a MIX of U.S. and British English.

In terms of image resolution and burst rates, 20 fps Live View on the R5 is nothing to laugh at and if you need a HIGHER BURST RATE, the video capture option will be either at DCI 8K 8192 x 4320 pixels (35.38 megapixels) or UHDTV 7680 by 4320 pixels (33.17 megapixels), so it's basically a VIRTUAL BURST RATE of 30 fps and ANY magazine editor WILL ACCEPT a 35.38 megapixel or a 33.17 megapixel video frame grab as an "Action/Sports Still Photo" !!!

I've done it MANY TIMES with the Global shutter Canon C700 Global Shutter Cinema Camera using 60 fps 4096 by 2160 (8.8 megapixels) video frame grabs for my sports/action imagery. I am fairly sure YOU have probably seen some of my 8 megapixel frame grabs for my F1, Skiing, Soccer (Football) photos in certain European mags and newspapers (mostly in Germany, Italy and Netherlands with some UK). They tend to use them mostly for online use (i.e. DW.de & DW.com) BUT i've seen a few of my frame grabs in print. I usually cover North America BUT I've done onsite Euro too.

This Canon R5 Camera WILL cause consternation in many photographic circles becuase specs-wise IT IS quite excellent ....BUT.... there IS a competitor coming soon enough that is VERY VERY GOOD INDEED !!! So don't rest on your laurels Canon! This R5 is NOT the only game in town!
