nizar ghosn: how could you justify the better iso performance in the d610 in your comparison line on this page, despite the comparison chart shows that the d750 is better .. and why you have the handling of the d610 is better than the d750 in this page ??? is it ???

HAR,

No I haven't downloaded them I used the DPR studio scene and there's no difference. The initial 'superior' ISO comments on websites was based on the JPEGS.
As noted the lower noise in JPEGS is due to more aggressive noise reduction - the details are smeared in comparison to the D610.
There are comments that maybe the D750 has 'sharper' images because the ant-aliasing filter has been changed. However the actual sensor per se is most likely the same. And yes, I've looked at other comparisons too (over a few months) which is why I just bought the D810 as I saw no particular advantage in the image IQ of the D750 over my D600 and hence the D810 added something 'different'.

The D750 has lower noise in JPEG mode but greater loss of detail - a sign of more aggressive noise reduction in the D750.
The RAW files are identical - not surprising as the sensor is probably the same one.

MikeF4Black: I really cannot understand why my camera didn't get top ranking. What was DPR thinking of?

Marty, I fully agree that there's no real difference in the quality of products made with administration from the base company.
I recently sent a piece of electronic equipment to Japan for repair. The repair costs were quoted as twice the cost of a new item (made by their Chinese factory). Even the preliminary examination cost us 50% of the new item price (so I told them to dump it and bought a new one @ 150% of the cost - had to pay for the 'examination' anyway).
Lesson learnt.

Marty,
This was 'tongue in cheek' based on comments on forums that if it's made outside Japan it's 'of questionable quality'.

Because it wasn't made in Japan?

Summi Luchs: My guess is that they will use the sensor-shift to de-Bayer the image. They can move the red, green and blue pixels between the exposures so, that they get a full RGB sample for every pixel (like a Foveon sensor). This would not give us 'true' 40MP resolution, it is simply the same calculus of 'equivalence' Sigma uses for its cameras. (Sigma uses a factor of three, Oly gets a lower factor of equivalence, as the Bayer sensor is not RGB but RGGB).
The gain would be better color information, that what makes Foveon images special.

I don't think they do the same as Hasselblad and other earlier attempts to increase true resolution by sensor movements. Earlier sensors had more blind gaps between the photosites making such techniques meaningful. Newer sensors have a dense array of microlenses (to gather more light per photosite), so there is not much left to sample in between.

Oversampling each sensel 4 times would reduce the average sensel noise (and colour separation and tonality)? - noise is my biggest my biggest concern with m 4/3 more so than resolution.

thx1138: interesting that the D750 is better at ISO 51200 than the Sony A7 at 25600. I compared it to the 1D X and it's line ball even at 25600 and the D750 eeks out a bit more detail. Impressive given how good the 1D X is at high ISO.

Har,

Thanks, nice to get 'reinforcement' on the selection of the D810.

HaR,
Thanks for the information :-)
I'm buying the D810 to see what 36 Mp has to offer and also the build.
We'll see.
Now if there was a Df2 ......

HAR,
I agree that websites can be misleading - and even the forums are not always, shall we say, 'truthful'?
Comparing the Df/D4 using the tool would suggest that the D750 (or D610) are better at 6,400.
Thanks for your reply and honesty. Unfortunately I don't have the opportunity to try out and compare the D750 with my D600 under my own conditions - which is why I'm about to purchase a D810 for myself to see what I think of it on a personal level. I'm anticipating using it as a 'fair weather' camera under ideal conditions (low ISO) when I need the extra resolution (or ergonomics). In the future I'll look at a high ISO camera to replace the D600.

HAR,
"It's a significantly better high ISO camera than the Nikon D610, despite both having 24MP sensors."
Well having gone through the studio comparison tool the D610 actually seems to have lower noise.
However, the D610 image is not as sharp which might explain why.
In reality I doubt there's any significant difference between the 2 sensors - even with the change in 'Expeed' processor.
Of course Nikon (and review sites) have to say the IQ is 'better' as it's a newer camera.
Given the choice between the D6X0 and a D750 I'd chose the D750 because of it's enhanced AF and other facilities - but not because of the sensor.

You're probably correct - somewhere in the region of ± $7,000. I should really have just said 'affordable'.
Nikon don't have any affordable lenses for enthusiasts over 300 mm (i.e. the 300mm F4)

Tord S Eriksson: "Allison was quite smitten"

That's the comment your lady coworker gets by you guys?!

In this day and age?! And naturally her head is cut off.

Seems you "boys with toys" were smitten as well, by the "old guys" syndrome, where women at the best are allowed to hold the lenses, unless they are big and hefty, when you guys take over!

Richard,
Heaven forbid if you'd have said something like 'Gobsmacked' rather than 'smitten'. ;-)
