DxO 6D results are in: kinda outs the 5D Mark III

Canon EOS 6D: The best value for money in the EOS range? _ certainly interesting that Canon is finally working on technology to up the Dynamic Range for landscape shooters.

It is neat to see that the dynamic range of the 6D's sensor is right there with the 5D III and 1DX. It really is good news for 6D owners and prospective buyers. When comparing the DXO dynamic range test results between the 6D, 5D III, and 1DX (and even the 5D II for that matter), the difference between them is neglible in my opinion. When processing RAW files, you can readily notice the extra DR headroom from a 14.2 EV range sensor (Nikon D600) as compared to a 12.1 EV (6D) sensor. But, who's gonna notice the difference between 12.1 (6D) and 11.7 (5D III)? So, while the 6D appears to offer some DR improvement in DXO's tests, my feeling is that it is a negligible improvement.

I know that DXO is generally despised here at POTN, but my takeaway from their sensor testing is that, aside from low-light performance, there hasn't been a substantially noticeable sensor improvement over the last several years in Canon's fullframe cameras. And, more importantly, as a 5D II and III owner I don't even need DXO's numbers: I can readily see on my color-managed Adobe Lightroom screen that there is precious little image quality difference between the 5D II and III (except at very high ISO). I don't have or plan to get a 6D, but I suspect I wouldn't see much difference there either. I'm not writing this as a complaint, just as what I feel is a realistic observation. I'm very happy with both my 5D II and III.

So, yes, I agree that among EOS cameras, the 6D shows up very well; it's a very good value.

^^^ good reasonable comments above --- agreed.

David hit it on the money. End of thread

Quite a funny comment on that site, which seems quite reasonable:

I dont understand how the high iso measurement is achieved with dxo. From what I seen, the 6D crushes the D600 in high ISO.

I believe they resize all the images to 8 MP and then compare the noise.

By "crushes" do you mean "blows out of the water"? That seems to be the phrase people here like to use when comparing .... Anything else and folks seem to get a little confused.......

Another biggie phrase, here on POTN, would be "I pulled the Trigger and bought X". Correct me if I'm wrong, but I believe this is some sort of "Gun" reference? Still I don't quite know what guns and cameras have in common.......

^ You shoot with both.

From the looks of it, successful troll was successful lol

Ah... I see. and here I thought, all the time, they were pulling the trigger to shoot the camera.......

Comments from the peanut gallery are good too!

what is the point of your comment?

you are trying to make a point about common phrases that you somehow don't understand, but seem to understand just fine based on your "criticism"

OR

this is a really poor attempt at being witty that just falls flat on it's face (or fails super duper hard)

The point of the comment has two sides...

1. People love to say stuff like "blows out of the water" when in fact there is little or even no difference. Case in point would be that the D600 has lower/better ISO noise than the 5dmk2, so unless you think the 6D is just light years ahead of the mk2 (ISO Noise), the differences might not be that far apart. To spell it out and just to be clear, and without using humor; the difference in ISO performance between the 6d and D600 may not be that far apart. It's open to interpretation, but IMHO most would agree.

2. I try to wrap a little humor, from time to time, in my posts. Sorry you didn't enjoy it. It's nothing personal or an attack, so no reason to fret or take exception.

Quoting "Sports & action photography: Low-Light ISO

Unlike the two previous scenarios in which light is either generous (studio) or stability is assured (landscape), photojournalists and action photographers often struggle with low available light and high motion. Achieving usable image quality is often difficult when pushing ISO.

When shooting a moving scene such as a sports event, action photographers’ primary objective is to freeze the motion, giving priority to short exposure time. To compensate for the lack of exposure, they have to increase the ISO setting, which means the SNR will decrease. How far can they go while keeping decent quality? Our low-light ISO metric will tell them.

The SNR indicates how much noise is present in an image compared to the actual information (signal). The higher the SNR value, the better the image looks, because details aren't drowned by noise. SNR strength is given in dB, which is a logarithmic scale: an increase of 6 dB corresponds to doubling the SNR, which equates to half the noise for the same signal.

An SNR value of 30dB means excellent image quality. Thus low-light ISO is the highest ISO setting for a camera that allows it to achieve an SNR of 30dB while keeping a good dynamic range of 9 EVs and a color depth of 18bits.

A difference in low-light ISO of 25% represents 1/3 EV and is only slightly noticeable.

As cameras improve, low-light ISO will continuously increase, making this scale open."
