Hello all,
I am a new users here. I have been reading this forum for many years, but never bothered to register. Well...there is something that made me register today - it is the rumor about the new high MP camera from Canon and the reaction from people.

It is no secret that people are hard to please. Let me tell you one thing, Professional and serious amateurs in the field of Landscape, portrait, architecture and studio photography will buy this camera like mad.

I am the one. I only do Landscapes and portraits (www.lightpilgrim.com) and this camera has everything I need:
1. Most probably a very clean ISO 100 - this is what I use 100% of the time for landscapes
2. Very good DR and plenty of details - I am dreaming about it for landscapes
3. I will be able to print images that have more details and that are sharper

I am perfectly happy with 5 FPS - I am probably going to be happy with 1 FPS for landscapes:-)
I have never done anything beyond ISO 3200 simply because I only want to have top quality, clean images.
I started with 40D, then I went to 5D MKII and then to 5D MKIII and I never used video. I am just this kind of guy that needs a perfect tool for landscapes and portraits...I am not dwelling on things that I did not use or needed for years.

I think there are many people like me....

So I personally want to thank Canon. I will wait for review and I think I am getting this camera.

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?

no, if it 7Dmk2 pixel structure it would be 0,3-0,5 EV better at base iso than 7dmk2
if it is a Sony inside you have at least 14 stops DR and well known CFA

When comparing a new camera to the 5D3, I think it's reasonable to ask for better low-light performance, or higher pixel count, but not both.

This camera has more than twice as many pixels as the 5D3.  If it were built with the same sensor technology, we should expect it to be about 1 stop worse on low-light performance.  That is, a shot at ISO 400 on the 5DS would look like a shot at ISO 800 from the 5D3.

We can hope that advanced sensor technology could cancel out that disadvantage, and bring the 5DS low-light performance back to the level of the 5D3.  But I think it's ridiculous to expect better low-light performance from this new camera.

If low-light performance is the most important thing to you, I suggest you check out the Sony a7S.  It's a full-frame sensor with just 12 megapixels.  Those pixels are HUGE, and this camera can effectively see in the dark.

If you want to stick with Canon, then the 5D4 is your best hope; similar pixel density to the 5D3, but with improved low-light performance.

"As one example, the selection of a CFA, the color pattern put in front of the sensor, is a choice between quality of color, and ISO performance. If the CFA allows each pixel to see a broader spectrum of color (e.g. for the green pixels to see a bit further into yellow) a camera’s ISO range can be modestly increased. The resulting loss in color quality is subtle – subtle variations in color are missed and a handful of specific colors become difficult to photograph. In a market where a ISO 25,600 camera has a leg up on a ISO12,800 camera, the engineers are under enormous pressure to pick the modestly increased ISO over subtle color quality."

Thanks for the INFO. But that did NOT in any way answer my question. I suppose most people here are clear that High ISO means low DR When you split in three RGB Monochrome signals it is more than clear that with high ISO you get not so nice images.

And yet my question was related to: "colour that actually eye perception is UNABLE to differentiate?"

Ugh so I'm gonna have to buy two cameras this year? One for portraiture and one for events?

NOOOOOOOOOO

You already have one for events. Did your 5D3 suddenly become useless?

<p>The first thing people have noticed is the maximum ISO of 6400 for both the EOS 5DS and EOS 5DS R.</p>
<p>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.</p>
<p>The EOS 5D Mark IV will be the camera geared to sensitivity and lowlight performance and we will see one sometime in 2015.</p>
<p><em>More to come…</em></p>

if this is true it sounds like a Sony Exmor inside

Can't wait to see sample images and sensitivity comparisons...

Actually NO! The trend with MF is to optimize the ISO availability ;-)

A plea to the more knowledgeable people here:
Could you please enlighten me why Canon is going for colour that actually eye perception is UNABLE to differentiate? Or I misunderstood it?

You can read this about the Phase One IQ250

http://www.luminous-landscape.com/essays/the_phase_one_iq250_cmos_fully_realized.shtml

quoting the section on the CFA:

"As one example, the selection of a CFA, the color pattern put in front of the sensor, is a choice between quality of color, and ISO performance. If the CFA allows each pixel to see a broader spectrum of color (e.g. for the green pixels to see a bit further into yellow) a camera’s ISO range can be modestly increased. The resulting loss in color quality is subtle – subtle variations in color are missed and a handful of specific colors become difficult to photograph. In a market where a ISO 25,600 camera has a leg up on a ISO12,800 camera, the engineers are under enormous pressure to pick the modestly increased ISO over subtle color quality."

The trend of going to more ISO in MF is because CMOS has become available just recently. The olde CCD tech was just not capable. Still The IQ250 is capped at ISO6400.

Stay at MF-oriented forums for a while. Color is a big thing there. What's real and what's imagined differences is harder to understand, but even microscopic differences are important to that kind of users. So if you want to get good credibility in those circles this kind of optimization, regardless of how subtle it is, is valuable.

EOS Bodies / Re: WIFI, GPS?
« Last post by JonAustin on Today at 09:29:41 AM »
I wonder why the list does not mention wifi or gps. I find it difficult to imagine it will not have wifi at least (especially after Canon said that improved interconnectivity was one of the ways they wanted to regain lost DSLR sales).
depends on the chassis - the specs say full mag alloy. it may have GPS aka 7DII but probably not wifi.  canon's implementation of wifi requires some part of the body to have a plastic chassis component.

Not necessarily so. I think you're confusing body with chassis. The WiFi antenna would of course be placed within the body, but not inside the chassis.

On the topic "which version to get" that is with or without AA filter

I'm sure we'll see a couple of hundred threads in the future on this issue :-p

I'm curious about the Dual Digic6? Isn't the dual chip usually implemented for higher FPS or something?

At the 50mp data rate, 5 fps *is* "high" fps!

Really like the idea of crop modes (assuming full RAW) but if the top ISO is only 6400 in crop mode, and how could it not be, that would be a half empty.

Fyi: On current cameras, iso 6400 is the highest setting *anyway* - everything above is more or less digitally amplified, so you can just shoot raw and underexpose. But as no one realizes, it will enable Canon selling both the 5ds and 5d4.
