Why Canon need a new sensor with low read out noise
Apr 27, 2013

A digital sensor/camera  with great DR means also exposure freedom.

This is inside a church and the light in the roof is the the high light, 5dmk3 and d800 are exposed identically time, f-stop  so there will be reproduction of the high light with out any clipping when the high light is adjusted the same in camera raw .

Then the rest of the picture are handle in the same way regarding middle tones and down in to shadows .The results in noise and details   is shown here.  100iso 1/80 sec F1,4  canon 35/1,4 and Sigma 35/1,4

Its becoming quite boring now.

We all know a better sensor would be, well, better. Why we have to have thread after thread about it is beyond me.

From a photographic perspective, there is no reason to lift shadows here. Moreover, D800 here is pretty noisy too, you wont use it for any decent purpose. You can argue that a car with two wheels is better than a car with one wheel. But in reality, you need a car with four wheels. I own a D600, I know what I am talking about.

It would be nice...
In reply to Mikael Risedal, Apr 27, 2013

I don't know if I would have done the image below much different but it would have been easier to process and the image quality in lower light areas would have been somewhat better.  Currently, it is not worth changing camera bodies for this issue for me.

I can see your point, I'd definitely be giving that camera to some starving human and the red

and text all over the images, unusable.

Has technology taken the fun out of photography ?

Why don't you repeat the test at iso 3200  and up (of course, using the same cameras !).

1dx and nikon d800 at 12400iso, Im impressed of the d800 results

next 1dx and d800 at 25000iso, the signal in d800 are now weaker which can been seen in the shadows/lower levels and Nikon start twisting at red.

I think the contrary. That is nice detail to have.

Depending on what you mean by decent. I think it is decent enough for a lot of purposes which the 5D3 image would not be fit for.

You can argue that a car with two wheels is better than a car with one wheel. But in reality, you need a car with four wheels.

Except in this case 5D3 is the car with 2 wheels and D800 is the car with 4 wheels.

I own a D600, I know what I am talking about.

Since when does ownership automatically become the certification of one "knows what he is talking about"? Does that mean those who do not own D600 must have no idea what more DR is all about?

1dx vs d800 100iso shadows
In reply to Mikael Risedal, Apr 27, 2013

1dx is much cleaner than 5dmk3 in the shadows/lower levels, my question is,  why have not Canon done anything similare  with the read out from the  5dmk3 ?  John Sheehy wrote years ago it is pure sloppiness from Canon side and   not take care of the read out noise/ banding. 1dx shows less banding and noise compared to 5dmk3

Worth noting is that the 1DX and D800 have the same total FWC from the sensor

well did you know the big difference between 1dx and 5dmk3 in lower levels?, I was surprised, it means that if  Canon want they can use the same readout solution  and make  for example 5dmk3 a h.... much better.

dont understand, my point is, the rest of canon SLR can  with little effort from canon show the same cleanness as 1dx

Can you post the final post-processed uncropped photo for each camera?  It will be interesting to see the overall image you are trying to achieve.

I find this there thread much more useful than the "I love Canon camera skin tone rendition".

A lot of posters have argued that high DR is not needed in "real world" photography and this is a good example to prove otherwise.

I'm regretting selling my D800 now specially after getting my 24-70II for my Canon 5dMK3.

This combo in nowhere near performance I was getting with the Nikon equivalent.

This is your 1254th samples..:-)

Why don't you link us the raws?

I am sure It is possible to do a much better work with the cry from 5D3. The magenta tint is much more correctable. I doubt you do the worse post production you can from the 5D3 file to show with more evidence what you want.:-)

We know you are no happy with canons!;-)

We know also that the D800 is incredible, but you should use better the 5D3 to obtain better pictures from the camera.

The photographer should use in the better way his camera.

Please, if you aren't a troll, link the two raws with the same exposure. Thanks.
