fPrime: DPR: We understand that the color filter array on the D5 sensor has been changed to improve low light performance. Can you comment on this?

NIKON: It’s very difficult to explain exactly how we achieved this, but the basic concept is that we improved light-gathering ability. And by doing that we reduced noise and increased sensitivity.

Thanks, Nikon... with every iteration you give us optically thinner CFA's to support your drive for higher ISO's. But then color fidelity suffers from weak CFA's that are less able to strictly separate light into distinct color channels. The RAW color transforms used to compensate for this on Macbeth color charts in turn twist neighboring subtle hues in unintended directions. No wonder why color enthusiasts users don't upgrade their old cameras. Better to buy another legacy color champ body on Craigslist.

hey, I find this CFA stuff interesting. Where do you go from here, when your 700 bites the dust? Obviously you can replace the shutter, but there will come a time?

Which old models for you have the best colour, can you go through it with me? I used to love the D700 - but didn't really know why at the time. Any others?

fPrime: Automated AF adjustment for high resolution sensors has been way overdue for years now. This firmware option should have premiered in 2012 with the launch of the D800 with it's woeful left AF focus issues. The fact that this is launching in 2016 with only support for calibrating the center AF point under one type of lighting should be an embarrassment for Nikon.

When this can be automated for all AF points at all zoom positions under multiple light sources, it'll be a worthwhile upgrade. Until then let's call this very minor improvement to DSLR focusing tech what it really is... a half-baked step in the right direction. Underwhelmed.

Exactly fprime, it's just laziness so forgive me if i don't jump in singing Nikon's praises. They better step it up a whole lot more, they are lucky they have a good lens lineup. Who is running this company these days? Totally asleep at the wheel in a lot of ways...

thxbb12: AF calibration: this is the very reason I switched to mirrorless about 3 years ago. I'm so glad I did.
Eventhough Nikon's implementation is very useful, it's still suffering from many downsides. The real fix is to achieve AF on the sensor. There is really no way around it, no matter how much duct tape we put around it ;-)

Mirrorless AF is guff, in 2015, 2016...A DSLR (pro level) easily outshines mirrorless AF even if I don't calibrate it. So let's nip that one in the bud pal.

MarBa: Finally!!

I always check if my lenses are properly micro-adjusted by doing something similar by hand. Use contrast focus ... switch to phase focus and see if it refocuses (or other way around). Changing micro-adjust until it is OK.

Automating this is great but there really should be some sort of memory to store various levels of compensation for different distances and light temperatures for each lens (or focal length in case of zooms).

I hope other camera companies will adopt this as well!!
Thanks Nikon for starting it!!

in 2016 this should be possible.

Totally agree. They need to step it up a whole lot more! Also I don't see why it should stop at one value. As the writer says canon has adjustment for the near and far end of the zoom. But why stop there? In 2016, the software should be able to take a prime lens, say a 50mm, and automatically do x3 shots near mid and far and choose values for each. Why should be be using x40 to get a "best fit" value for sharpness for subjects across different distances? Is nikon suggesting that my said 50mm lens can only really be used at one subject distance to get best sharpness, the moment I change that up I have to refine tune to that distance. That is what I have always found odd and sloppy about the AF fine tune on cameras. I always noticed if i calibrated to close distance when I took shots of people far away the system missed those. Come on, what a joke!

MarkByland: I think the accuracy of the D750 is the information to glean from this video. The A7 seems relatively soft in all the shots. Also Using a D21 focus point array in low light is photo suicide for any action like live bands. Spot metering is the only way to fly, and using of AF point selection during key anticipated moments.

I have used the Sigma 50/1.4 EXTENSIVELY when shooting live bands with a Pentax K-5, traditionally, not much of a low light focus performer. Average 9/10 in focus, properly exposed for the scene, and never hunted.

Then, there's manual focus. In which I prefer to trust over any AF mechanism. It worked for decades and still does. Long live the OVF and turning the hand slightly for better shots.

fatdee, you can clearly see sony has back focused on the hair and the eyes are blurry in 3 out of the 4 shots, it doesn't matter this is a compressed 2MP video. I can see the eyes are the focal plane in the D750 shots and not in the sony. Not the case for the D750. WHICH is using a flippin 50mm lens vs a 30 on the sony, (which is easier to keep focus when tracking) and the fact sony gets a native lens vs 3rd party for nikon. If you think this test is fair, what kind of person are you?

The portrait is beautiful, stunning light, would like to see hair down without the "wind" though.

Mirrorless Crusader: These images are average quality. The composition is good but not great, the saturation levels are appropriate, but the white balance is blatantly and arbitrarily warm in many of the images. The lightingwas very poorly done in some of these images, especially #1 with the foreground being desperately needing flash and in some other images the flash was used inappropriately. Overall I would grade this a C+. I certainly could have done better with thousands of dollars worth of gear and enough money to spend all day taking pictures without having to work for a living.

Disagree with number 1 needing flash...The subject - the piece of wood / door. Is well lit. The sand doesn't require it IMO.

Only problem is to the uneducated it looks like a fu**ing bomb!

Lensflair: Second on first glance the D800 appears to be a huge technical leap because it is 36MP on a full frame sensor. But as many have pointed out on the forum, pixel density is comparable with cropped sensors such as the 7D. So in reality from a pixel density point of view it is more of a huge marketing leap that will appeal to those who don’t really understand sensors and think that the bigger the number the better. Thirdly I don’t think Canon have been left behind, but rather they have chosen a different path that in reality you cant say is better or worse than Nikon, it is just different. Canon appears to value sensitivity and noise over shear pixel count on their full frame sensors. Fourth, I would suggest that the majority of people would not notice a real difference in an image from the D800 vs the 5D3.

If canon had the 36MP body you'd argue to the death that 36MP was good and the bigger the better. You are evidently hurt that canon have not really delivered what you wanted, why the heck else would you be posting on a D800 user thread if you are a canon fanboy wouldn't you stick to canon? Why are you here, come on tell us? The canon sensor has only 11.2 stops of DR compared to 14.4 for the Nikon, the portrait bit depth is poor compared to the D800, etc etc the canon sensor is a weak update with autofocus as the 5d was a manual focus camera, wasn't it ;-) What is funny is people are taking your troll bait on here, it's evident what you are and why you are here. Go outside and get some sunshine mate. Get a life more to the point!
