Yxa: Rather pleased with my D800 compared with the 1DXII DR-range
No catching up here, trailing as usual

D800 line cannot give you so mucb FPS, because it is bandwith limited, especially when sitting in lower class and price range, than a flagship. 1D line also cannot do 36Mpx at 14 FPS, right? But you can do 14FPS with higher dynamic range and lower shadow noise. FPS actually doesn't have to close to anything with DR...(Yes, bit depth takes data to move).

justmeMN: Girly Men can't handle a camera that's this big. They have to use mirrorless cameras. :-)

Utterlyotter: I see those manly men in search of mirrorless setup on flagship forums (years later), crying and telling stories about carpal surgery. :-)
I will be one of these, propably...

andyyau: Try to see 80D and 1DX2 skin tone of the girl on the right side. New Canon sensors all produce yellowish skin tone. This is not acceptable...

Nikon, on the other hand, often gives absolutely red, burned look to the girl on the right. And when I try to set colors of the guy on the right to the same as Canon has, the girl goes even deeper red. Not good. Compromises and decisions, that´s it... Maybe different CFA with different spectral response. One quiet minute for oldschool sensors please!

Marcus Antonius: Why is no one talking about the softness in the 1dxII image?
Something went wrong there imho.

Look here: http://bit.ly/1rUiS63

Exactly. WHUUUUT? :-)

TORN: asi if it was IMPOSSIBLE to shoot 14FPS with higher dynamic range. C´mon! Logic101 and healthy thinking. Canon just doesn´t give us any...

Dutchphotographer1: Interestingly, if you select full size instead of comp size in the DR comparison (comp size is the default view for DR comparison, but full size is the default for the studio comparison), the per pixel noise it equal to the Sony. The sony's advantage is only from the downscaling due to the higher megapixel count. On a per pixel basis, Canon has fully catched up with Sony (although with slightly larger photo diodes in this comparison, which gives a bit of an advantage). If canon is able to maintain this per pixel noise on a slightly higher megapixel count for the 6DII and 5DIV, they will be on a level playing field DR wise.

Anyway, I think that far all practical purposes, the image quality is so close, that it is irrelevant in real world usage.

I wonder how big market is there for high DR sensors. But I believe it is big enaugh for manufacturers to acknowledge and act on that. When I looked for upgrade, it was like "oh look", there is (actually old years) like new Nikon with 24Mpx FF sensor and high DR for less than $1000.
And then: "Oh look, there is no Canon available at any price, giving me that DR, and no Canon available in the price range for the resolution, and no Canon available for competing in FPS in that price range (except of crop sensors with even less resolution and DR). No competition in major/vital specs from Canon at all. Then we wonder how come Canons income goes downhill. There is something really crappy about this strategy.

I see. But I would rather go less zoom or no zoom for hetter IQ instead of this. Those qualities of 1" sensor are mostly wasted here.

crashpc: That´s what you get for small lens with large zoom ratio. MF is awesome. FF could "go". APS-C will get the duck and go, and MFT,where it breaks would still pass and go. 1" device? Errr, no. Not with these lenses. Please, do some better lenses for this awesome sensor!

Hhh. Touching flash capacitor contacts is best experience I got from teardowns. It will teach you how to handle unknown things...

phazelag: I wonder where all the arm chair lens engineers who have repeatedly told us what cannot be done will hide now?

jaykumarr: Yes, that might be global consesus of armchair warriors, who propably think that image quality has direct correlation to focal lenght. This might not hold true, as Sony could produce poorer quality unsharp lens, as they did for RX1 (corners).

Canon had this 7 years for us. Now you come to the party Nikon?
It must be Canon sensor, no doubt.

Lan: Dear DPReview, please dock Nikon 20% from their final score for the D5 for providing that headline ISO 3,280,000 setting; as it sets an all time low in image quality terms.

I would also suggest that we need to beat Nikon's marketing folks with a wet haddock for creating that option... Given the image quality, I think think a frozen haddock would be the best form ;) In fact I'd recommend an entire box full of them at once. Repeatedly.

Bar of soap in a sock....

crashpc: ISO 204000 is propably where it should end, even for emergenices. After denoise and sharpening, it´s good for 640px wide image.

Forgot to write that after ISO204K, it seems the color and all artifacts go significantly faster "overboard".

Link | Posted on Mar 28, 2016 at 18:33 UTC

Seems that ISO 204K is where it should stop. Good for 640px wide image. Past that, the image has banding, purple-violet colouration, and the overal quality is not good for images larger than 100px.

bildsee: When looking at the sample pictures I noticed some color banding in the lifted shadows of image 37 (tree bark on the left side): http://www.dpreview.com/sample-galleries/7982275943/canon-eos-80d-real-world-samples/2499681722

So I checked whether Canons DPP 4.4.20 would handle this better. Those who are interested may have a look here:
http://www.dpreview.com/forums/post/57496492

Looks like DPP gets much more out of the camera's RAW file, which should not be a suprise since DPP has been developed by the vendor itself. Still, this should always be kept in mind when rating and comparing IQ,
processed by different tools.

Finaly the 80D seems to be a big step forward, regardless which software used.

Thanks for the nice article.

For long time, I got better results with LR compared to DPP. This would be interesting turn if anything changed...

On photo Feeding in crashpc's photo gallery (2 comments in total)

Hello. This was first season ii had some time for birding. Oo the performance of myself is not on top of what I could possibly achieve if I was more skilled. All long reach shots have been taken by old kit lens 55-250mm IS II. It needed to be stopped down a bit to get sharp, or usable results. My new STM will be "maidened" this spring and summer. It is sharpest when wide open, faster, quieter, doesn't move with focusing and it accepts some TCs well, without much loss of image quality, still wide open, so I hope for more and better shots... That lens is simply awesome, compared with old II version.

photomedium: As usual, Canon nibbling at the bullet instead of fully biting it. At least they found it in themselves to admit that it is actually nice for people to have 12 stops DR, and finally gave in and put the preamp and ADC on sensor.
However, since this is still the 1st gen for them, they will have to jump through the hoops to get it right. Knowing how Canon operates, they will go through all the twelve-steps, eventually discover Cu works better than Al, BSI works better than non BSI, etc etc. Every step will be marked by much fanfare, marketing videos with lots of fancy CGI, and price increases.

Yes, they do. But pro shooters are not that cast of people, makig Canon biggest profit. All these will get pulled into hell too. :-)
Or rather they´ll solve their situation with other competitive brands, as many already did...
