DPreview adds 6D sample images to their preview

[dtaylor]

There's either an exposure or a levels difference between the two. I don't see any real difference in noise. If there is a difference, it is well below the threshold of differences introduced by post processing (NR software and technique).

The 6D shots might be a little bit underexposed compared to 5D3 but nevertheless, I can see it a little bit better than 5D3.  Besides, generally underexposure usually means more noise when processed.  Is this NR or is this really a new sensor technology?  Let's wait till December. 

You're assuming underexposure vs. the tonal curves of the cameras (or some related setting). At 6400 there's no actual resolution difference, and little noise/contrast/color difference which disappears with a levels adjustment.

At 102k there's more of a difference at first glance. But it could still be due to the camera tone curves.

Sorry, I think people are getting excited about JPEG processing. And not even JPEG NR processing, but small differences in image parameters between a consumer and a pro camera.

Previously in another thread, I've raised the possibility that 6D is built on an entirely new generation of sensor.

Definitely not, this was already ack'ed by Canon - it's the same sensor tech, though the 6d has a bit little larger pixels for the loss in resolution. The reason probably is that after the criticism about the lack of advancement 5d2->5d3 Canon had a 3/4 year time to optimize everything else.

If you look at the exif data, all 6d shots have a shorter exposure time then the 5d3...

but small differences in image parameters between a consumer and a pro camera.

However, this shows how desperate the Canon crowd is for sensor advancement ... the Nikon competition obviously has left its mark :-> ... and again, imho there is no fixed distinction between "pro" or not except for marketing, why not use the 6d if it is at least as good or even better (low light af) for some shots?

Agreed! If the low-light AF functionality of the 6D is as advertised, then it certainly caters to a different group of photographers. Body is still magnesium alloy reinforced after all. What's really missing is the lack of the advanced AF system of the higher-end models. Maybe eventually, the 6D would also be used as a backup body for when low-light is needed.

Personally, as long as the 6D doesn't perform poorer in the IQ area compared to the 5D3, then its certainly a viable option for people like me who don't really take much pictures of moving subjects.

What are you talking about?

I just compared the 6D at ISO-6400 vs the 5DIII at ISO-6400 ... and the 6D is cleaner and with better colors.

Overall, the 6D image quality is shaping up as better than the 5DIII.

yeah well if details in the images don´t count for you.... the images look good.

but im only interested in low iso.. (100- max 1600) im not needing these incredible high isos for my shots.

and like the 5D MK3 i see no real improvement compared to the 5D MK2... not in these samples.

And that wasn't to be expected - for lower iso shots the 5d2 should be great (actually even little better than the 5d3). But most people who upgrade to ff want to have the medium-high iso capability, meaning ~6400 which is exactly what is really missing from the crop sensors and in this region there is an improvement over the 5d2. I agree crazy-high iso speeds are mainly for marketing.

[Gothmoth]

And that wasn't to be expected

yes it was not... but i really hope we will see a new process (180nm) soon.

then the great camera bodys will be joined with even better sensors.
and for low iso, high quality landscape and studio photographer, who don´t care much about AF speed or AF tracking, there will be a reason to upgrade to a new body.

These are out of camera Jpg's. They look identical to the 5D3 files but only with more NR in camera.

[Area256]

it's nice to know that Canon has given DPReview a pre-production camera to play with.

Where did you get this information? Everywhere I look it has the "The camera used for this gallery was pre-production, and image quality should be considered 'Beta' standard" notice, though that probably only means the in-camera raw-converter / jpeg-engine and not the sensor hardware.

It's the logical conclusion that DPReview got a pre-production 6D from Canon.  How else would they have been able to take sample images with it?  These aren't samples Canon took themselves and sent to DPReviews.  How closely this camera comes to the production camera is anyone's guess.  Although if Canon intends to have these in stores world wide for Christmas, I'd bet they are already in production, and the only thing likely to change is firmware.

Sorry, of course you're correct - I mis-read your post :-o

Look again, for example @iso6400 on the fur of the mouse on the left - there are more details in the 6d even though it has a cleaner background, so it's not just more nr. But still doesn't mean much since it's a comparison of two beta in-camera jpeg engines with too high nr settings...

Meh. If there is any tiny difference, it will be irrelevant in real world use.

Sure, though we'll only know for sure by looking at studio shots after a 6d raw converter is out. And concerning the dpreview shots: Actually I looked again and the focus on the 5d3/6d shots is a little different, so even @f11 that explains some differences.

[Ryan708]

Those shots looked surprisingly good to me. How do you guys think this will compare to the 5dII at say ISO 3200? Im going to be in the market for one of the two eventually

On another note, I recently found out why the 6D was designed without a multi-selector.

Here's a hint, The 5Dc and The 5D2 really didn't need one either.

Unless we see raw files taken at exactly the same studio conditions the only thing we learn is that the jpeg engine is better at 6D.

I wish I have 6D on hand for side by side comparision. The math doesn't seem to add up, $2100 body is perform better than $3500 in high ISO with same sensor.
