EOS Bodies / Re: Bingo! New Canon 5Ds has 50.6 MP new rumored specs

Figure this, at 50mp, will it be the equal of a Hasselblad? No way. Pixel size does matter. Larger ones are typically better, but when you are constrained by 35mm format, fitting more means making them smaller. Increases in resolution comes at the cost of smaller pixels. Thus, smaller pixels will have to become more efficient and accurate. The rumored 6400 ISO is an indication that efficiency wasn't increased much at all - they're just putting out high mega pixel count.


K, I agree with most of your comments. This one, I'm not so sure. If the smaller pixels were the reason for the ISO 6400 limit, would we not see the same limit on the 7DII? I believe the pixels are about the same size, yet the 7DII goes to ISO 16,000. In addition, it has been reported that the quantum efficiency of the 7DII is higher than that of earlier Canon sensors, including full frame.

I would think the biggest differences/advantages of medium format are:

1. Shallower depth of field.
2. Larger sensor = more light.

Anyway, food for thought...

I thought the limiting factor in this case was the heavier CFA design.  Get more color depth, sacrifice sensitivity?

Yep. That's what's being reported, and it would seem to make sense to me. Still wondering if there's some artificial limiting at play, too, in order to more clearly differentiate this body for its target segment...

Absolutely. This is (hopefully, pending tttmnbso* results) the camera I've been waiting for to become my Canon landscape camera.

LOL! I love it. Thanks, jrista!

I have lenses to shoot anything. However, I do a lot of targeted street photography where I cannot control any of the surrounding circumstances. Cars and people get in my way. Disturbing backgrounds popping up from nowhere. Unruly pedestrians wanting to pass me during a shot. Good scenes appearing and disappearing in an instant.

Cropping is an essential way to help me focus those shots on what I want to show and get rid of all the urban "noise". A ruined full body shot can thus often be saved by cropping the picture into a close portrait shot in stead.

I am sure others also have their reasons to crop a lot regardless of arming themselves with the "right" tool for the right job. Not all of us have the luxury of having control over our subject and surroundings.

Great point, Maiaibing. I often find myself cropping for similar reasons. Sometimes I frame for one composition, but some time later, I'll see a composition I like even better with some cropping. To me, cropping is one of the tools of the the creative process, and 50MP would sure enhance that.

It all comes down to philosophy of use, and that can vary a lot from one artist to the next...

... except for shots with blown whites, because clipping keeps being clipped no matter how you downscale, denoise or crop it.
Must you insist on repeatedly bringing reality into this discussion?  ;) :P

Yes, because I use ML's dual_iso fro 14+ ev dr all the time and have settled for the fact that indeed ~20mp is fine for what I do ... so Canon releasing a 50mp sensor makes my head all fuzzy and I have to do a reality check :-)

Nailed it.  I keep wondering when Canon will bust that feature out in native firmware rather than a Magic Lantern hack.  dPAF seems ideal for it.  Maybe in the 5D4

I'd love to see this, too. Good for the guys (and gals?) at Magic Lantern for pushing the capabilities of the Canon system to new levels. Might light a fire for Canon...

And thanks, Marsu, for touting ML so often. There are probably a number of members here who heard about it first from your posts...

Famateur, having read the last few pages of all your posts, I have to say you're one of the few on here who really gets it.  Canon has obviously created a whole new line up to suit each professional need. There won't be 4k on the 5Ds because it's not meant for that.  My prediction is that we see a 1DX2 before the 5D4. Both of these rigs will have 4K.  The 1DC just got a $4000 price drop. It's now $7999.  Releasing a new 1DX2 also at $7k+ makes no sense with a 1DC at the same price.  The 1DC is being phased out I bet. The 1DX and 1DC will become the 1DX2.  A 1DC now is nothing more than exactly a 1DX with 4k added.  If a 1DX2 comes out with DPAF...which it most assuredly will... A 1DC is suddenly a bit of a dog.  What I think we will get at the end of the summer is an all around 25mp ish 5D4 and 20.2MP 1DX2 both with DPAF and 4k capability with the 1DX2 blasting 14FPS, some obscene number of AF points spread wide across the frame and fabulous low light high ISO ability along with the full time video AF features in the 7D2 and maybe even a Real audio preamp for mic input.

Thanks...it's fun trying to piece everything together from a combination of legitimate clues and wild speculation. :P

Your thoughts on the fate of the 1DC are interesting -- the price drop sure seems to be a signal that they could make a major change in the Cinema line.

One thing is sure: Canon is making a move, and that's exciting (to me, anyway). There will be plenty who complain about the move, no matter which way it goes, but I'm still excited.

I'd rather use 36MP Exmor for that stuff than just 14MP more and worse DR.
Not holding my breath, but if the rumor that it's a Canon sensor from a new process is true, we could be pleasantly surprised on the dynamic range front...

Canon increasing dr *and* res significantly at the same time? "Oink oink flap flap" :-)



Love the image, but there's just not enough dynamic range in the scene to impress me. Maybe if you had shot it directly into the sun...  ;)

Seriously, though...you may be right. It feels nice to hope, though, even if it might be a little naive. :P

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).

It's probably reasonable to suspect that the video side will be lacking since if it will have 4K, it would likely be in the rumor. Still, I would consider video features to be unannounced and unrumored. If it is lacking, then I agree -- let's hope the stills performance (for its studio/landscape market) is a grand slam.

Agreed. Otherwise, why put an "S" as the model designation?

Just pondering on the ISO 6400 rumor for the 5DS...

I wonder if the explanation of the stronger color filter being the reason is just what the public is supposed to know. It wouldn't surprise me if it was a limitation built into the firmware (or even hardware), for product differentiation purposes, and not an actual limitation of the sensor itself.

I remember upgrading to an 8Mpixel camera and thinking "WOW! This is great!!!!" We live in great times for digital imaging.

Amen to that!

I laughed so hard I fell off my chair!!! I fully agree. But that bit about upgrading the brain was pure genius. That's exactly what I think I need to do.
Cheers
Ray

That's easy enough with a firmware upgrade.  :P

Ray, pleased to amuse you!

Famateur: Well, Lumiquest III 9" x 8" vinyl/cardstock softbox is made in the USA, as are the Lastolite TriGrip/Flip diffuser frames (I think they may off-shore the sewing of the slipcovers that go over the diffusers), and the Lastolite diffusion/reflector fabrics may be USA-made. I don't know about the gels, I think that they are USA-made also. Rogue products - some made in China (flashbender?), some in USA (injection-molded snoot/grid). Books - written in USA, printed in USA. RF triggers/ receivers - cheap ($30.00/ pair) simple ones made in China.

I think that our fantasy kit would boost the world economy some, the actual kit less so.

Being in the USA myself, I'm fine with boosting the global American economy.  8) ;)
