I guess these stats show:
1. More people have mobiles than dedicated cameras.
2. More people carry their mobiles with them more often than cameras.
3. More people with mobiles use Flickr than dedicated photographers.
Otherwise these stats are pretty worthless.

RichRMA: Very good shots. Big cats are being poached by hunters working for places like China and Vietnam where tiger gall bladders, etc, are used in quack medicine. It's a good idea to find alternative areas for them to live, like perhaps wild areas in North America because where they are living is not longer viable.

Marsel,
I'm not decrying any attempt at saving a species by whatever means necessary. However providing an environment that is conducive to breeding is required which it would appear that you're providing.
However, as you and I both know, poaching in SA is big business and if the price is right then there's no hope for the species concerned.
I still don't understand the killing of an animal unless for necessity - i.e. food value - just to have a rug in front of a fire or a trophy above the fireplace.
I 'shoot' with a camera that does little harm.
I do, though, wish you success in your enterprise.

If one wants to prevent the elimination of a species one has to stop the demand for the products derived there from.
Those that do hunting do so 'for pleasure' or to earn money to survive.
Removing the animals from their natural habitat where they can live and breed to another habitat where they will still be hunted (or just die off) and not breed makes no sense.

North America with the largest cache of guns - and arguably the largest population of trophy hunters - is a viable alternative to their natural habitat?

Merry Christmas to all, especially the DPR staff.

Guess you'll be back with mouth watering reviews in the new year - for equipment that we can no longer afford after Christmas spending sprees :-)

Enjoy your well deserved break!

turvyT: D750 looks wonderful until you compare it in lab test section with Pentax 645z. Then, image quality wise, D750 looks just like one more of the pack. I know that IQ only doesn't say much about usability, but the difference is impressive.

Rishi,

I guessed that most would be waiting for the reviews of the more affordable cameras for Christmas purchases so you'd get those out first. Understandable.

@ Rishi,
Well I don't know whether to buy the D810 or not because I'm still waiting for your review! :-)
(In jest, I bought one 2 weeks back :-) )

Digital Mike0697: Has anyone notice there is a problem with lens flare on D750? Nikon Rumors, is stating there is a problem. I want to know before I buy the camera.

Thank you.

There might be in a set of limited situations. But this shouldn't stop you buying one if that's what you want. The solution seems straight forward and easy to fix by Nikon - if the rumour is correct and /or the frequency of having the 'flare problem' is bothersome.

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'.

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.
