EOS Bodies / Re: More About the EOS 5DS & EOS 5DS R
« on: January 30, 2015, 02:04:06 PM »
Guys, please pardon my ignorance but I'd like to clarify the ISO question. If Canon 5ds has Sony sensor and let's say you shoot at ISO 3200, would you be able to push shadows 1-2 stops in post-processing like for D810? In this case, would ISO 3200 be kind of equivalent to ISO 6400-12800? Sorry for my very naive description of what I wanted to ask.

Pushing doesn't just push the shadows, it pushes everything.  Canon sensors are already as good as the rest once you're at ISO 400-800 and above so no difference there.

Another question is, do you guys think there's any chance 5Ds would come with integrated non-detachable grip, like 1D series?

I sure hope not, and I doubt it.

The latest update from Canonwatch:


    50.6MP full-size CMOS sensor (53MP total count)
    5DS R is without low-pass filter
    Magnesium alloy body
    Dust and water sealed
    Dual processor DIGIC6
    Regular sensitivity ISO 100-6400, expand to 12800
    Continuous shooting 5 frames / sec.
    High precision 61-point AF, 41 cross type
    EOS iTR AF
    150,000 pixel RGB + IR photometry sensor
    Added “fine detail” to the Picture Style
    1.3x and 1.6x crop shooting mode
    Customizable “Quick Control Screen”
    Time-lapse movie
    Anti-flicker
    Interval Timer
    Bulb timer
    No headphone terminal
    No DAF
    No HDMI output for video (clean out). Not to compete with 5D III other video features are same.

The source also stated that the sensor is made by Canon using a new CMOS manufacturing process.

So, who's first to pre-order one?

If that's really the spec list, I probably wouldn't pay more than the cost of a 6D for it.

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.

Any thoughts on lens performance?  Will the higher resolution push the capabilities of the current L series?

Not even close.

We’re told this is because of a much stronger CFA which will produce much greater color accuracy than anything currently in the Canon lineup.

I'd be incredibly shocked if this made any real difference in color performance.  Current raw images have way, way more gamut than any of the spaces we use and we have plenty of ability to find the right color in those areas with the possible exception of the whole purple/violet issue.

I've never found color accuracy to be a problem with any sensor, given raw shooting and processing with good tools.

Just compare an older Canon with a newer - for example 1Ds Mark III vs 5D Mark III. The color balance and accuracy out of camera on normal ISO is much better in the old-timer thanks to a thicker CFA. Files simply need less work and that might be a huge time-saver for many photographers.

Well, I have a 5D and a 550D, and I just don't see any real difference in this area between those two, and they would, I would guess, represent opposite ends of the spectrum in this area.

I disagree, I find when correcting color with my Color Checker that introduces noise that I could do without. To able to get correct color, and especially skin color, without the color checker would be fantastic!

A stronger CFA is going to give you less light captured and thus more noise, not less.

What does the "R" stand for?  Ridiculous?  Retarded?  Wretched doesn't seem to fit (that would be a "W").

I have read more than once that high ISO ability takes something away from low ISO- you can't have both with current technology.

Please ignore such claims.  Anything that helps at high ISO helps at low ISO as well.  Some things that help at low ISO help less at high ISO, but this isn't tuning an engine for low RPM versus high RPM.

what I don't get though is how many negative comments here.  It's like the past 2.5 years of canon rumors posts  and posts just flipped over to the bizarro world.  For 2.5 years - sonikon has XXX MP"S and sonikon has XX DR - and how canon FF bodies are only suitable for FB selfies and kneel and pray to exmor, oh holy exmor.  Now we hear of this ---and yes this is a rumo spec list - no cr rating at all and the majority of posts want ---high iso and low light capabilities?????  REALLY????  Did the past 2.5 years just happen or did I blink while the majority of folks here had their priorities change???  Get a grip people!!!

I've wanted a high pixel count sensor (with cropping options) forever, but base ISO DR means essentially nothing to me.  My 550D has plenty of base ISO DR.  I do want dual pixel.  The whole reason I want full-frame is for better low-light performance.

If the specs are true, this camera meets only one of my required specifications for such a camera (high pixel count with cropping) and fails at the others (better low-light, dual pixel).

if this is true then snag yourself a 5d3 or 6d and shoot away!

No, that wouldn't solve the problem (undersampling) that a higher pixel count would solve.

if dual pixel is an absolute need, then get a 7d2, or, wait until the next group of FF bodies is released.  DPAF is a new tech, it's only in 2 bodies so it's time to get whats thee or wait.  But if like you say -- "The whole reason I want full-frame is for better low-light performance," then stop complaining and grab a cheap 6d or a 5d3.  This new beast is a specialized beast ---and yeah, I'd rather have a specialized beast if it kicks butt in what it's made to do rather than a crippled beast that had huge files and crazy iso's but no improvement at the base ISO's ----now that would be a FAIL!

Frankly, dual-pixel has the capability to improve base ISO DR more than any of Sony's sensor technology.  Using dual pixels and simultaneous different exposure has the ability to get you to 20 stops with 7DII pixels and nothing but software.

And I still think base ISO DR is a relatively unimportant parameter.

Why couldn't you have a body that could deliver 10 fps in crop mode?

Because you'd need a very fast mirror assembly.  If it has that, then fine.  If not...you can't do it.

Often over the course of DSLR history the processing speed in a large part dictated the fps.
Keep in mind mirror assemblies that could put out high fps in a full frame body is old technology.
It would make this camera an all in one body.

Yes, we have fast mirror assemblies, in some cameras (1Dx).

No, this wouldn't make it an all-in-one body, at least without dual-pixel and high ISOs.  These pixels are the size of those in the 7DII, and that camera goes to ISO 16,000.  There no reason I can think of that this camera shouldn't do the same.

If, as I suspect, such a camera is aimed firmly at  'detail' photographers, then it will elicit howls of derision from many quarters.

If ISO only going to 6400 means that results are better at 100, then so be it.

One has essentially nothing to do with the other.

Does DPAF contribute to image quality at base ISO, or hinder it?

Helps, if done right.  Think ML dual ISO done with separate sensors in each pixel.

I don't understand the narrow ISO range.  This is the same pixel size as the 70D and 7DII which go to 12,800 and 16,000 respectively.  This camera would be 1 1/3 stops better at the same final size or the same at the same enlargement ratio so I don't see why they'd restrict it so much.  One of my only disappointments with my 5D was the ISO range which was 100-1600 with 3200 as the extension.  It was fine for many purposes at 6400-12,800 using the underexpose and push technique.

Of course it's just a rumor so it could be wrong.

Also, where's dual pixel technology?
