TORN: Cutting minimum shutter to 1/4000s and lowest ISO to 100 is making pretty sure I don't buy it. I do not use zooms and I do not intend to run a selection of ND filters because of marketing caused camara restrictions.

Well I do have enough cameras but hey Nikon listen: You want to sell something, right?

But it doesnt have the 1/8000 shutter.
At least not that a user can get to.

RomanP: I don't get what the big deal is here, for the price:
- same body as 610 (except tilt screen)
- same toy-like 4way selector...really inferior to the 810's and 5D's.
- same sensor
- same 6fps. Wait, that's now 6.5fps.
- same buffer! Really, they couldn't double the RAM?

Is it worth an $800 difference between the two models? Yes, better autofocus system, but IQ will be very close, and you won't get more shots at an event than with a D610. It's like Nikon is crippling this model only to queue up a truly high speed 760s next year.

Just see the D750's buffer in glorious action here: https://www.youtube.com/watch?v=L1wXGdaNvko

RomanP why do you keep quoting that you tube link?
The guy is uisng a slow card.
In reality the D750 is capable of much high and longer continuous bursts.
If you actually want to see what the D750 can do in a continuous burst, try this one:

Note the improvment here is write speed, not buffer per se, but it is an improvement.

DPR either works for you or not.
There's nothing wrong with offering an opinion on methodology etc, but at the end analysis, you either want to use it, or not.

In reply to:

Ron A 19: Seems like the D750 seems to have a sharper image at full resolution, but could this be partly because the Canons are using a lens that is 22 years older? The 85mm USM cannot outresolve the 85mm G (compare them on thedigitalpicture.com). If DPReview wants to compare these two cameras on a resolution basis, why don't they use the same lens on different bodies? A third party reference lens like the Sigma Art or Zeiss otus would be the perfect way to show limitations of a sensor rather than a cheapo circa '92 lens.

Then it will be the AF, if used, or "does the Sigma 10 1.4 ART allow for different filter stack thicknesses...".

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.

Well if you compare the D750 with my ipone 5, the D750 clearly trounces the ipHone for IQ....
And at only 2-3 timnes the cost, not the 3-4 times the cost ofthe 645z.
Clearly better value.

I'd love a 645z - but that is a dumb a** comparison which makes you turvyT a dumb a**.

In reply to:

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.

Its a real problem but it appears to only occur on less than 10% of all D750s, and it seems most people only see it when they try to reproduce it. I.e. it seems it does not happen with normal photos for most people.

The phenomena also happens with lots of other cameras - it is not unique to the D750.

It probably is not a manufacturing problem and *my guess* is that simply changing one or two components in the camera will make it go away.

In many maybe all cases the lens hood prevents the problem, so it is really a problem only for people who want lens flare as a creative choice.

There's a few long threads in the forums if you want to get a fuller story, but the above is my take and I've been watching the issue develop since it was first reported here around 3-4 weeks ago.

I wouldn't let it stop me from buying a D750 - it's an awesome camera.

Nothing to see here.
Move on.

manaca5: Got the D750 shortly after it came out and added a 24-85 3.5-4.5G kit lens. Have owned it for 5000+ pics now. I have or need nothing that this body can't give me. It's fantastic. I shoot soccer (70-200 2.8 VRII + 1.7), indoor basketball (85 AF D, 1.8 & 70-200 2.8 VRII), portraits (50mm 1.8 G, 85 mm 1.8 and 70-200mm). And I am trying landscape more with the kit lens at 24mm and a Tokina 11-16mm 2.8 (at 16mm). Image quality is fantastic. I love the narrow DoF I can achieve so easily now. The 50mm prime is the go to lens for most non-sport shooting. Only minor issues I see, the eye cup pops off often. It's worth looking at other eye cup options.

Available dynamic range has been a real bonus with the snow so far. Ergonomics of the body are great with the new grip (better than D7000 for long shoots). The new battery grip is too expensive to justify (and unavailable). I am looking for good portable wide angle lens options with this body, but will have to save up.

Some DX lenses have an image ciricle that is big enough to cover an FX sensor at certain apertures or focal lengths.

Usually at the longer FLs (if zoom) or smaller apertures.

in addition most Nikon FX cameras will detect a DX mode and can be configured to only use the DX protion of the sensor, at lower res, e.g. about 10MP for the D750 around 16MP for a D8x0.

If you use the DX on FX feature you a DX sized frame line appears in the viewfinder, which gives you something like a rangefinder experience, in that you can see things about to enter the frame.

On the D750 you can also use 1.2x crop mode if your DX lens circle won't cover the entire FX frame, but is bigger than a DX frame.

I haven't shot the 6x0s but the 750 has the following over the 6x0:

Arguably the best AF system Nikon has (depending on which paramaters you value most) Group Area AF (my default area mode now), highlight priority metering, 91K metering sensor (which feeds into the AF tracking and face detection), ISO is maybe a stop better, Tilt screen really useful (for some of us), Wifi Handy at times, OK button to zoom to 100% or 200% (really handy), nice Auto ISO implementation, weak AA filter, face priority, it's all little stuff and add's up to nice.
Sort of the same as a D810 versus a D800(e). A whole lot of small changes that add up to a fair bit, but 1 by 1 don't sound like much.

Video
Zerbras, onscreen histogram, 60p, aperture control (stepless), stepless auto iso, adjustable audio levels, auto AF does not suck as much.
Most of that is a big deal for DSLR video.

And the grip feels really nice in the hand.

NeilSDPR: Looks like a very good camera, however for the reviewer to state that the 5D lll AF system is behind the times

I don't think so

I imagine the engineers are thinking something along the lines of
"...don't't all these whiny photographers ever read about the laws of physics or optical design..."

En Trance: Also, if I rest my camera on a good tripod at the beach, 1/4000 does not cut it due to the wind alone. (Especially with a tele lens) After that, I begin to think of exposure. Why is Nikon limiting their shutter speed so severely?

Granted. The D750 is IMO an awesome camera and the 1/4000 shutter is a relatively minor issue.
But it is IMO an unnecessary issue.

Nikon are depriving us of an occasionally useful feature and they don't need to.
IMO the shutter speed is not a sufficient point of of difference to change people's purchasing choices.

@HOWABOUTRAW

I think you're making too much of the use of "focus" instead of "sharpness". It's close enough to understand what he means.

He said what the trouble was: wind.
He also said that a faster shutter speed can be part of the solution. I think he's right.

I've only had this problem once myself about two weeks ago with a borrowed Bigma.
I shot just fine with my Tamron 70-200 on the tripod.
But with the Bigma at 400-500mm there was so much more movement due to wind. The surface area of the lens is greater so it catches more wind.
So much so that I gave up.
Part of my problem was the tripod was too light (Manfrotto mt294c3) and I did not have the gear to ballast the tripod.
But the problem is real and allowing for

I actually didn't think about shutter speed as a solution, but I think he's right if you can get a sufficiently high shutter speed it will probably eliminate or considerably reduce the problem.
It words when you have hand held camera shake, should work for tripod too

I think En Trance means sharpness rather than focus per se.
I.e. blurry images due to camera shake i.e. wind moving the lens.
Long lenses are particularly suscpetable (I recently found out) due to their increased surface area compounded by the long length.
I was fortunate enough to to hit the trifecta and had mirage too. ;-)

@RomanP

If you're going to rely on Youtube videos to assess products you should either be more careful about who you trust for your info or choose a broader sample.

I strongly suspect if you present cherry picked results that demonstrate poor performance as representative of the best a camera can do you're gonna get found out.

Here's a different view of the D750 buffer and imaging pipeline when a higher performance SD card is employed.

http://youtu.be/fyrZ0rj2BNk

I will personally back the veracity of this video, as I shot it.

It's not a D4, but the continuous burst length is better than the specs might lead you to believe and indeed is better than some Youtubers using lower performance cards, might lead you to believe.

Rick_Hunter: This is a gearheads gathering place. You can put out any, really, any camera you want, but if it doesn't have at least a GAZILLION megapixels, and UMPTEENTH stops of DR, and a FEMTOsecond top shutter speed, etc, people here will always complain because they can't possibly take proper images of their cat, or of their lensalign ruler. Infact, how could they live with such an inferior camera? Bottom line, most gearheads here wil ALWAYS see only the empty part of the glass, even when the glass is >90% full.
Just give up already...

@Rick Hunter I would characterise most of the threads here as people exchanging information and therefore learning.

But you're essentually correct in your characterisation that this is a gearhead/tech head forum.

Which invariably involve lots of debate about a few percentage points of performance difference.
You know that, you came here.
You get annoyed by it.
I'm thinking your glass is <%50 usable capacity.

mpgxsvcd: What are we all complaining about? Just 6 years ago we had pathetic burst rates, 12 Megapixels was the Max instead of the min available, Video was non existent, Quiet shutters were almost unheard of, Auto Focus was only slightly better than manual focus, and the cameras cost more than they do today.

If you can't take great pictures and videos with the latest cameras then you really can't blame the camera anymore.

...
I'm no longer a software engineer , but I used to be employed professionally as a software engineer (on embedded systems no less) and had undergrad training as a computer scientist.

I'm fairly confident at least some of my conclusions are reasonable based on the evidence/observations available, to me.

But as I say above, I don't have access to Niko spokespeople.
I'd love to hear Nikon's official line on the questions surrounding the differences feature sets with what would appear to be common code bases and similarly specified pipelines, if you'd care to query your Nikon contacts.

Continuous shooting limited to 100 shots.

The argument I've heard against longer continuous bursts is heat.
But we know the sensor can shoot 60 fps for 20-30 minutes in video mode
And we know the EXPEED 4 implementation in the D750 can shovel data through at 3fps, we pretty sure the shutter can do it.
e.g. if we lift our finger from the shutter button for a split second at the end of a 100 shot burst the D750 is quite happy to shoot more images with no further break.
So it's hard to believe the hardware can't shoot 200 frames the same as the D4s.
So it seems to me that someone has gone through and changed the
#define CONTINUOUS_BURST_LENGTH 200 and changed it to 100.
Again it really looks like they're trying to protect the higher model.

But to me there is sufficient differentiation in the models anyway just in the naturally different features.

It seems totally unnecessary to make these changes and worse probably adds to the cost of producing and testing the code.

@Rishi
re 1/8000 I don't have access to Nikon people but in video mode I've seen 1/8000 appear on the LCD on my D750, therefore I assume that the camera is capable of shooting it.

By unnecessary crippling I meant that it is not neccesary to differentiate the D750 from the D810 or the D4.
You may have already taken that away, but I'm not sure, hence the clarification.

And things like the OVF level only operating in oneaxis are for sure uneccesary.
The scale for the fore-aft (pitch) in landscape mode is there - it's used for the horizon in portrait mode and we know the camera can measure both horizon and pitch, as it displays both n LV and I think the D810 does both, in the OVF so someone basically went through the code base and disabled that feature.
They went out of their way and turned it off.

That is unnecessary and arbitrary and I can't see why you would do that other than to protect the "higher" models in the line.

Compare is visible on Chrome Version 39.0.2171.95 (64-bit) on OSX 10.9.5.
So I'm not sure what's going on in the Widows version.
Have you checked that you have the most recent Chrome?

AllOtherNamesTaken: Pretty crazy that the 5DM3 is still priced anywhere near $3,000. You'd have to be out of your mind to pay that in this environment unless you absolutely needed one for a job or something.

@Hedley7D, indeed I might change my opinion about Canon bodies in Feb.
And the same for the Nikon lens range (less likely).
The point i was trying to make though wasn't that Canon bodies or the Nikon lens range is that either are arbitrarily poor (or fine), it's that both systems have weaknesses.
I'd even extend that all systems have weaknesses, even the elder, more complete systems.
I have to admit I shoot Nikon and I think Nikon bodies are currently better and have been for a while, but if I knew what I know today, when I bought my first "serious" camera, I'd probably have made a different decision.

My complaints are not with the camera per se, but with what I see as Nikon unnecessarily crippling certain features to create an artificial differentiation in the range and I think this is more obvious and less needed in the D750/D810/D4s sub range.

D810 and D4 have their own "killer apps", headline features which will drive people to them anyway, not to mention the fact they are more expensive so a certain class of buyer aspires to them anyway for status.

Deeper buffer, lower/higher ISO, view finder bllind - I can see they may all cost more to implelent.

But the 1/8000 shutter, single axis level in OVF are just arbitrary and unnecessary crippling.

They are not features most epople will pay an extra $1000 for.
I want 1/8000 but not enough to spend $1000 for, I can spend $80 on a decent ND and get essentially the same effect.
I don't think Nikon is thinking these kinds of decisions through very well.

Especially if they don't want the 36MP sensor.
