Possible Canon EOS 5D Mark IV Spec Talk [CR2]
- Thread starter Canon Rumors
- Start date
See the Sony A7s. Went to 12MP to get the best possible low-light for video and stills shooting. Canon has their big MP monster, and the 5DIII will still exist...but, if they want to target the video community, something that comes close to the A7s in low-light and 4k internally would be a pretty huge leap for Canon.Patak said:
Combo'ing that with 12fps would make this an even bigger jump than the jump between 5DII and 5DIII

Also worth noting that NorthLight Images listed a rumor saying there would be a general purpose Mark IV and then a 5DC (cinema) version as well (Link:http://www.northlight-images.co.uk/cameras/Canon_5d4.html)
The specs listed sure sound like a cinema version to me...

"4k video" is 3840x2160. At a 3:2 aspect ratio, that would be 3840x2560, or 9.83MP.
I doubt they'll go there.
So that leaves either cropping to get 4k, or downsampling to get 4k.
The C100 pixel bins to get 4k. The way it does it is essentially 2x2 (binning the greens and recording to the red and blue).
That would be 2*(3840x2560) = 7680x5120 or 39.3MP. I suppose that one could be credible.
Or, they could just do some form of downsampling and/or skipping. Problem is, downsampling from, say, 18MP to 4k (8.3MP) is pretty computationally intensive, and doing it 30 or 60 times a second uses a lot of power (battery energy).

Canon said earlier that they will move away from a global model that shoots everything and develop cameras with specifications suited to the needs of different photographers. I think the development of the 5DS along with the proposed specs here for the 5DX is a reflection of that thinking and it makes perfect sense. This camera looks identical to the current 1DX except it's rumored to shoot 4K as well. I don't see that as a drawback. The sensor will probably be a refined version of what's in the current 1D X, not bad either. If they offer this camera for $ 3K price, it's an awesome deal. You'll have your high MP 5DS for landscape/studio work and your high FPS / high ISO 5D X for sports/bird/street photography.Patak said:

I didn't say Canon has to outgun Nikon. It will just be difficult to compete for a 18MP sensor when the equivalent camera class of the competitors differ so much in MP count. Experienced and capable photographers of course don't just look at the MP count but it is also not as simple as when people say the lower the MP count the better.
The 5Ds and 5DsR are really niche products to mee (so far). It seemed to me Canon wanted to show what they can do. When I look at the specs besides the sensor, I am not impressed, as in may aspects they are a step back compared to the 5D III. And as Canon said themselfs, these cameras are not meant as replacements of the 5D III.

I do find the drop in pixels to be surprising given marketing always seems to suggest more pixels are always better. My primary photography in past 5 years has been birds and to my eyes I have found cropping small pixel images a lot turns feathers into very flat looking photos. Whereas when cropping my larger pixel 5D3 images (sometimes severely) there is still a sense of depth to the feathers and overall the bird looks more pleasing. I guess my eyes just like the look of larger pixel sensors.
The camera in this CR2 rumor is essentially a 1D-X with 4K video. Offering 12 fps and 18 MP sounds exactly like the current 1D-X, which is why I would not get too worked up over the rumor. That is a LOT of action performance. While I would greatly welcome a 5D4 that had these specs, I am not seeing it coming to fruition. I pray I get to eat some crow feathers later.
The D810 competitor will not be a 5D4 body like this rumor. Different markets. Not everyone wants high frame rate. I do. The 5D3 is an "up to 6 fps" body which loses frame rate as the batteries discharge. At 50% battery level the frame rate is about 4 fps, maybe a hair under. When trying to get action sequences like a male bluebird feeding his offspring, 4 to 5 fps can mean missed shots.
And to show how different people want different things, if the 5D4 had 36 MP I would avoid it like the plague. I am glad Canon has produced high resolution 5 Series bodies for those desiring high resolution. I just hope the 5D4 and subsequent models avoid the high resolution part and continue to improve in areas such as higher ISO, improved AF and higher frame rate. Whether the sensor is 18 MP, 22 MP or 24 MP is mostly irrelevant for me.

The difference in resolution between 18 and 20 megapixel is irrelavante, but for marketing looks like a downgrade.Lee Jay said:

Just a test camera. When you consider the specs of their competition, there's no way it will be 18MP. Some cool features though.

It does sound like a 'test' body, and probably the final version would be very different.
The thing I'd be concerned with is the CFast cards. As a 5Dmk3 owner, I would hate to have to buy all new cards for a new camera, especially ones that are certain to be more expensive and not certain to become an industry standard (QXD cards anyone?). That alone could force me to stay with the 5Dmk3. At least I would be able to get another one really cheap.

This is just one of what is likely several test cameras on the streets, and, it might be a year old!
I am one who would get a 1D X instead as well. Prices for gray market models have dropped to very close to the price of a new camera, and it uses CF cards, so no need to spend $750 for a couple Cfast cards.

I don't want to buy two different bodies with different capabilities where I have to swap the lenses to use each bodys special features. I am very impressed by the 5Ds's but what body to choose? Prices are o.k. but I would easily pay 4000 €/$ if they had made a switchable low pass filter.
IMO a logical new incarnation of the 5D main line would have 22-30 MPix, the same frame rate, 4k video and high DR/colour accuracy/good high ISO capabilities and excellent ergonomics. Add wifi and a tilt screen for situations where you have no access to the OVF.
Bringing four or five 5D flavours to market is only logical from the marketing side: Sell more bodies. The moderate prices for 5Ds and 5Ds R might be a hint for that transition.
More and more I tend to buy a 5D classic or two if I switch to full frame and check if full frame is interesting for me.

You okay with that switchable filter requiring you to partially disassemble the body?

"You will need to use a T6 Torx driver to install and remove a DSMC Interchangeable OLPF and an LED flashlight (or similar) to ensure no debris or contaminants are visible in the optical cavity before inserting an interchangeable OLPF.
NOTE: It is not required, but RED highly recommends performing an OLPF swap in a cleanroom environment."

Don't get people dismissing even the suggestion of a camera on the basis that its rumoured spec doesn't meet an arbitrary pixel count of their wanting. 18MP on a 1DX is plenty for many uses and delivers files with plenty of capacity to crop and print large. You want more from Canon? There's a 50MP model with different crop options already slated.
And why is a new card format an issue? I use the same cards in the same cameras, every day. Shoot, take card out to edit, put card back in, shoot again. If you're spending £2-£3k on a camera, another £100 odd for a superior format card to go with it seems perfectly reasonable.
