sony is an exception to the rule, the SLT robs the camera of light, hence the low scores.

Charlie, that's exactly my point if we take that one step further.
Lower scores in almost all measurement categories, still, the overall score is 7 higher than the 6D. Why? Because DXO apparently generates their final scores mostly based on how the sensor performs at base ISO, which is arguably only a small percentage of what everybody shoots with their FF cameras in real life. I probably shoot ISO 100-200 5% of the time max.
So if you're a landscape or real estate photographer for example, or someone shooting in the studio at ISO 100-200 DXO is more valid to you. To me as an event, wedding, and fact action bird photographer, I'd be worse off using the higher score A99 than using a 6D or 5DIII.

I haven't read all the way through this thread. But I just wish all the canon users would vote for change with their wallets. canon would do something then.

The high ISO ability of the sony sensor is fairly good, I would put the A7r sensor on par with the 5D3/6D up to 6400, really neck and neck stuff. Past that, noise is about on par with the 5D3, but the colors start to get funky. The D750 looks to beat the canon sensor everywhere, including really really low light. Probably not a huge defeat in practice, but bragging rights, nikon owns it completely.

For humans, I say canon has the huge edge with skin tones. I have a few presets in lightroom to help out, really careful white balance in camera helps out as well, but it's not quite canon SOOC, but manageable. It just takes work to get the skin tones really good like canon, and I find this to be a huge deal. If I give out two of the same photo printed at 8x10, I'm sure a majority that view it side by side would pick the canon photo. Colors kinda matter a lot, more than pure resolution/iso performance/DR. Fortunately sony has really good white balancing tool built in, and I can quickly and easily WB anywhere I go.

Hard to tell with only 1600 on the long end, those are at most a 5x7 print size? Look great for 6400 on the screen though.

Too expensive to do so for those of us invested in lenses. However, when it came time to replace my work camera, Canon did not get my $$.


Not sure why, but call me JJ.
I used to hate math but then I realised decimals have a point.

I understand the sentiment but lenses hold their value pretty well.

At least you made your decision for where it really matters, your work, to move away from canon.

DR difference between 70D and 6D is negligible. There is a bigger DR difference between D750 and 6D than 70D and 6D. Are there any DR advantages with FF sensor?

I'm confused as to why you're throwing the 70D into the mix. ??? That's an orange and the comparison is for apples.

Thanks for the link Paul.
Now I can sleep without worries. :)
Most of what I shoot with my 5DIII (ISO 1600-3200 low light event stuff) has about the same DR as the Nikon D750. Every other measurement category are very close between these 3 cameras.

But no doubt, the 750 sensor is really good, based on the samples I've seen

I am just trying to compare DXO numbers between various cameras from Nikon and Canon along with D750 and 6D to get a feel of numbers. I do not know how they measure these numbers and how much these are useful. But except for low light iso, even Nikon crops are showing better numbers than 6D in DXO test scores. Surprised that Nikon D3300 which is going for $400 with kit lens producing better DR and color depth than 6D. Are these numbers real? Does it mean one can get better landscape and portrait pictures with D3300 than 6D.

right, I forgot about that, had an issue with people taking my photos, so I just changed my settings.

I do have some candlelit stuff with the A7r, and it's fairly good for what it is.

SOOC attachments @ 6400

full image + 100% crop of a 36mp file. If you resize it to 20mp, it would match or exceed the 6D. At higher isos, the 6D wins, even with the resize accounted for. That's my opinion based on usage rather than scientific comparison.... and I have a fairly demanding eye for this kinda stuff :p

dynamic range with the sony sensor will be similar, whether FF or crop. For instance, the A7r shoots 36 megapixel in FF mode, but there's also a mode to shot APS mode with 1.5x crop, which still gets you 15mp or so. Dynamic range didnt suddenly change, I still have the same sensor, but just less of it being used. The dynamic range will be better from an A7r to a 6D, there's no dispute there, however a cropped A7r image vs a FF 6D image, the 6D image will have considerably more detail and better noise control at 1:1 pixel level.

that's pretty much why different formats shouldnt be compared directly, even with similar megapixels. I'de say that the dynamic range is better on the smaller nikon sensor to the 6D, however, the 6D will produce much better images on a whole.

DXO is an independent lab. The numbers are real. You're probably just stunned at the poor results for canon.

Poor results? 6D? Ouch :) I think I'm going to go ahead and cancel my wedding shoot tomorrow. My 5DIII is even poorer than the 6D... ;)
At the same time many of my Nikon user friends envy me for better skin tone. I tried to console them saying that DXO's color sensitivity test shows their Nikon is superior.
This is just a joke (the second part is) but I couldn't resist. :)
