EOS Bodies / Re: Where is the EOS 5D Mark IV? [CR2]
« on: Today at 01:26:40 AM »
I don't really need anything more than the 5DIII, but I'm going to start saving in case this has Sony-like DR.  Instead of getting a new release 2-3 years after the release, this might just be one I get quickly.

My hopes:

24-28 Mp
4k video
8fps
Sony-like DR at base ISO (no banding etc...)
$3500

That would definitely be enough to get be buying quickly.  Even with 22Mp and no 4k I'd jump on it.

that would be nice (other than short on reach a bit) and in another 3-4 years merge this with the 50MP and then wow!!

There won't be 4k on the 5Ds because it's not meant for that.

Why not? How was the 1DC more meant for it?
If anything a high DR landscape/wildlife cam matches more to 4k than an ultra-speed brick action/sports body.

How are any of the DSLR meant or not meant for 4k?

Only if their is a tech reason can you say it was not meant for it (maybe there was, maybe not, you certainly can't likely expect a full sensor read from the 50MP cam for video, but a on chip bin mode like 5D3 seems like it could have worked, although I can't know for sure, perhaps not as maybe it is a Sony chip and Sony didn't make with binned 4k and Canon wanted a high DR camera and couldn't make one themselves and there you have it high DR amazing stills but no 4k??).

Don't need a tech reason. It's a model line up reason. This is looking like a studio stills machine.  With a separate 5D4 coming later, it seems to make more sense to drop 4k into your all-around machine... Because then they can sell it at 3500-4000 just like the 5DS will probably be and have that major distinction to justify the pricie strategy?  I'm guessing my friend

agreed - not to mention;

Some could actually think and go - hmm line skipping a 50Mp sensor would be HELL and horrid with tons of artifacts.
And then they could also go .. hmm.  binning each frame in firmware for 4k output would be insane on processing.

but no.. can't have logic and common sense ;)

you bin in HW not firmware, what good is firmware binning? at that point it means you had to have been able to read the entire sensor every frame so why even bin then if that was possible?

and the 5D3 bins 23MP so why three years later is 2x the bin crazy?

I mean maybe it turns out with how they make their chips it can't handle heat or whatnot of even a little more binning or mayne it's some thrid party chip thta just doesn't do it and that would make sense.

yawn.
the A7II has no 4K . heck even the A7S has no internal 4K.
the A7R has no 4K.
the D750, D810, D4s, D610 has no 4k.
do you see where I'm going here?  and some of these cameras are even brand spanking new.

so lots of other new stuff does and plenty more later this year
and you want to be a leader not a total follower

but if they at least get every bit of stills top notch....

still makes no sense, assuming of course there wasn't some tech reason like say it is Sony chip and it happens to not bin for video and that is that and they wanted to get us more DR and this was the only way, in that case it makes plenty of sense, otherwise not so much

So this is a camera optimized for low ISO performance. Canon is talking about stronger CFA and all of that....(which, given that for color depth above 24 bits is basically indiscernible to the human eye, is a total waste of time IMO. The only potential benefit MIGHT be lower color noise, if they are more finely restricting the colors through each CFA...but color noise would also be reduced if they would reduce their darn read noise.)


But once again...utter silence about read noise and dynamic range. This is, clearly, a Low ISO part from Canon. If they had resolved their low ISO read noise issues...one would think they would be proclaiming it to the heavens. Why the silence? :\


I don't want to lose the last little bit of hope I have in Canon...

The point you make about the read noise being an overriding factor is a good one and I agree.

Given that the information provided thus far about the camera is very preliminary, and we know nothing about the technology in the sensor, much less seen any actual images from this camera, there are "glass half-empty" and "glass half-full" viewpoints:

Pessimist view:  Increased color discrimination in this camera will be largely useless because Canon didn't improve the low ISO read noise.  Canon did it because all they can do is implement incremental, tangential improvements in their sensor technology, and cannot compete against Sony.

Optimist view:  Increased color discrimination in this camera was implemented precisely because Canon improved the low ISO read noise hence making the existing CFA performance inadequate, especially in post processing losses in color fidelity when bumping shadows by several stops.

Which one will turn out to be the case is unknowable at this time.  But the answer will most definitely determine the success of this camera.

Hell, basketball I never shoot over ISO 320.  It's either 320 or 160 but I strobe every basketball game, so this would be a backup to my backup.

Really?  Wow.  As a person who gets ophthalmic migraines from bright camera flashes, the first thing I'd do as a basketball player in a game you're shooting is accidentally on purpose crash into your strobes.

Since he used the term strobe and not flash, how do you know he isn't referring to the high above ceiling strobes that they have at pro arenas and at the bigger NCAA D1 schools?

If it has Canon DR and with the only 5fps and no improved video and no 4k then FORGET IT! It is a only a pseudo jack of all trades and not even close to a master of anything.

I don't think anyone is promoting this camera as "jack of all trades".  It seems to be designed as a master of well-lit studio, daylight and still life applications.

Demanding high frame rate and video out of that sort of camera is like expecting similar from digital medium format.

I'm sure that Canon will step up to the plate with an all-rounder in the EOS 5D IV come August...  Like you, I wait in fond anticipation.


yes but if it has Canon DR then it's not a master of studio/landscape stuff, especially not the latter

I'd rather use 36MP Exmor for that stuff than just 14MP more and worse DR.

Why would they put a top-of-the-line fast action AF system or 4K video in a studio camera with 50MP?

Because 4k video is big for landscape video and wildlife video work, things to which this camera is well suited (depending).

Of course there might be technical issues getting video out of 50MP (you;d think you could do the same 5D3 on chip video binning though and get 4k out of it though).

Since the video on it seems to be a joke, let's hope the stills are grand slam (exmor DR at worst, top color, at least 6fps in cropped modes, AF at least as good as in 5D3).

What does the "R" stand for? 

*Removed*.

They removed the AA filter.

Hmmmm.... CanonWatch has updated their post on this to reflect a CW# rating on the fact that the sensor has been made by Canon. Not Sony.  Hmmm... the plot thickens ;-)

oh no  :o >:( :'( :-\ :'(

just gotta hope they are wrong or they are using a new fab somehow....

On the topic "which version to get" that is with or without AA filter, it will depend if you care about pixel peep crispness or real image quality. AA filter is a good idea, sure it will reduce crispness but also take away most false colors and aliasing, and moire. Diffraction won't kill aliasing fully until you're up at f/16, so yes AA filter is the way to go.

But what will happen of course is that people will prefer pixel peep crispness over aliasing, jaggies, moire (because most don't really know about these issues or choose to ignore them) and buy the 5DsR and the next high res camera will only exist without AA filter, that was the case with the D800 and I think the same will happen here.

It doesn't say anything about a battery either, so does this mean we have to plug it into the wall? Damn....  And nothing about a warranty either. I guess Canon gave up on those too along with viewfinders. 

Think I'll wait for the official (and complete) spec list before I start bemoaning these cameras  ;D

Ha! Well said :)

Incidentally, a lot of people are taking the high ISO level to mean it'll be poorer in low light than the 5D3. At the risk of reopening a massive can of worms, isn't it the sensor size that's important? Like, if you downscale the 50+MP to 22MP, we'd expect it to be no worse, and maybe slightly better?

Yeah they might just be rating it on how it is using all 50MP, but if comparing at the same scale as 5D3 maybe it's the same or like only 1/3 stop worse (no big deal at all).

Looks like the rumours of a Sony-Canon 50MP sensor are true, even SAR states that one of his 'trusted sources' confirms this and SAR is a bit of a mouthpiece for Sony's marketing department to build hype.

If true then it looks like the Japanese camera manufacturers are in deep retreat in the face of falling DSLR sales. It looks like the Canon don't want to invest in a new fab line at this time, so they're outsourcing to Sony, at least for production. They are both scared -sales are falling and everything they try seems to fail to change this...

both the first global shutter rumor (i gave me the name KAI) and then the sony canon partnership was send in by me.  :)

both websites where happy to report this pure fantasy..

i still roll on the floor laughing....

Wow, you're pretty cool!

So a 30MP 1.3x mode and a 20MP 1.6x mode.

Comes packed with "extra reach" for birders :-P


very nice

I wonder why they don't give these modes a fps burst like Nikon does though? Nikon hits the critical 6fps in the cropped modes. Now a fast FF mirror box is expensive, but surely they could at least put a 6fps 5D3-class mirror box in there and easily drive 20MP crop mode at 6fps no? I mean the processor wouldn't even sweat, it has so much more power than a 5D3 which already drives 23MP at 6fps.

Of course the details might not be complete, maybe it does??
