The Nikon D750 in a demo of burst mode.
See the end of this description below to see WHY I made and posted this video.
The SDHC card is a 32G Sandisk "Extreme Pro" 95MB/s, Class 10, U3.
This video was created and uploaded by myself . in my lunch time using a phone, so sorry about the quality of the "cinematography" and sound.
However despite the visual and aural quality, I think it demonstrates my point.
Name the Nikon D750 is capable of continuous burst of 100 frames, with 14 bit lossless compressed NEF (RAW) files.
That is the highest quality available on the camera.
Just for kicks I also show 12 bit lossless compressed, 1.2x crop 12 bit lossless compressed, and 1.2x crop 14 bit lossless compressed.
400 frames, shot in 4 CONTINUOUS 100 frame bursts.
Looking at the video afterwards it looks like we got the following approximate lengths in time and initial burst sizes:
14 bit FX 36 seconds 100 frames, initial full speed burst 4 secs, 16 frames
12 bit FX 30 seconds 100 frames, initial full speed burst 5 secs, 22 frames
12 bit 1.2x crop 31 seconds 100 frames, initial full speed burst 8 secs,37 frames
14 bit 1.2x crop 28 seconds 100 frames, initial full speed burst 5 secs, 24 frames
The above times and frame rates are approximate, taken by eye and ear , I don't think I have the tools to do a better analysis, but I think they're pretty close within half a sec and a frame or two.
.
Since we know the D810 has the capability to shovel 36MP images onto it's card as long as there is room on the card and power in the battery it should not be a surprise that the D750 with smaller 24MP files and basically the same chipset/data pipeline (EXPEED4) can achieve similar performance.
Note that in all cases, the intial burst is longer than the estimate when you half press the shutter.
E.g. In 14bit FX the top LCD indicated 12 frames in the buffer but we got about 18 shots before slowing down.
No it's not the D4 or the D810, but with a fast card you can get an intial burst of at full speed, eg. 6-6.5 frames per second and then continue at 2-3 fps continuously without pause until Nikon's software decides you've had enough fun.
The 100 frame limit is arbitrary and imposed by Nikon, presumably to protect sales at of the D810 and D4.
There have been a few comments asking what the point of this video is, or questioning the validity.
The point was this www.dpreview.com/forums/threa... DPR thread, in particular as a reply to this particular post: www.dpreview.com/forums/post/... .

Thank you for the test! Did not think I could find an SD card that could write fast enough to allow the D750 to shoot for so long before quitting.

jtan163 that's impressive. If you choose the right SDXC card(Sandisk Extreme Pro's are awesome) this camera can do much better. I just bought the D750 and so far pretty happy with the shooting speed.

Thanks... I have a d750 and am trying to get it to shoot this fast.. right now it is shooting much slower... is it the quality of my sd cards? I shoot raw and then the camera saves out high resolution jpegs on card #2.... maybe this is the issue?
@1337flite
@1337flite 7 лет назад
Yeah to get high frame rates I think you need to make careful settings choices. Things that mean the camera's computer is doing as little work as possible. E.g. manual focus manual exposure no D-lighting no backup to second card no image review It's not very practical It's been a while since I made this vid and I did it quicly during a lunch break so I can't recall the exact settings, but if you search the DP revieew forums there are lots of tips for getting your frame rate up. I would guess writing a backup to the second card reduces the bandwidth available out of the buffer and probably reduces the number of images the buffer can hold and probably makes a significant difference. And I believe that good class 10 U3 cards make a difference.

Good job. Used my D750 at a wedding on Sunday with 40MB/s Sandisk cards 32GB, one in each slot writing 14 bit RAW to each (backup on slot 2), and the camera worked beautifully. Was using it alongside a D3 with 70-200 attached, the D750 is a lot nicer to carry around all day and the files look great. The fastest I ever shoot at a wedding is maybe 4 frames in a bit over a second for the first kiss so I don't need that kind of continuous shooting speed but nice to know it's there for other jobs as I will be buying a couple of the 90mb/s cards for it.

If you have a point it would probably be clearer if you articulated the point or explained the behaviour you have described. In the mean time I'm glad the video gave you a laugh.

The video didn't give me a laugh. His question "Have you tried the dx crop mode?", after actually watching the video, followed by your reply of "No, I've never tried the crop mode.", when you very clearly did, and replied to him in sarcasm, made me laugh.

LOL "100 shots without a pause" Dude I just watched the video and I can count, it got off 17 before the buffer filled and it dropped to about 2 fps.
@1337flite
@1337flite 6 лет назад
LOL someone who can't understand english. Yes it was 2-3fps but it was continuous at 2-3fps. I didn't claim a frame rate, just that it was continuous for 100 frames. On earlier Nikons in the same market position it would not continue to shoot at a constant/steady slow rate it would pause 10 seconds fire a frame, pause 7 seconds fire a frame etc.
@JohnLemieux
@JohnLemieux 6 лет назад
It'll take a million "continuous shots" until the shutter blows out if you don't care about the frame rate.
@1337flite
@1337flite 6 лет назад
Correct. Whereas the earlier models at a similar price point would not shoot continuous at a constant frame rate as their buffer would not clear fast enough. That was the point of the demonstration. I did not claim that the camera could shoot continuous at a high frame rate. Just that it could shoot continuous. That was a new thing at the time for DSLRs at the price point.

Probably you didn't optimise you settings. Did you check the settings in the description of this video - including the SD card model.
@sigmaandzeiss296

The D810 does much better than that and the reason is that it has a CF card which is much faster than those SD cards. Every pro camera have at least one CF card for a better buffer and faster operation. The 810 lasts at least twice as long before the buffer fills up and after that you can still shoot quite fast because of the CF card.
@jasont2610
@jasont2610 7 лет назад
No debate here (this is my video, for some reason my other account can't seem to post on you tube at the moment). Well not much debate here. Just pop your video up showing us the D810 write rate using SD cards :-) . Yes the D810 with CF does do better it should - it costs more and part of that extra money buy you more RAM. My D4 also has a much higher frame rate and longer bursts - and clears faster especially with XQD. That however does not change the point I was making or the validity of the video. My point was twofold: 1) the D750 buffer performance is better than it was given credit for or the specs might suggest. 2) certain SD cards get you better performance with the D750/expeed 4 than other SD cards. FYI I actually made the video to demonstrate these points to people in some forum who argued that what I demonstrated was not possible - this performance was not accepted at the time and was the subject of debate on DPR as well as other places. e.g. Thom Hogan changed his D750 review on both the area of buffer performance and video bit rate on the basis of this video and other information I provided him. Oh and not every "pro" (whatever that is) camera has CF cards - they're too slow these days. The recent high performance flagship cameras use XQD cards. (BTW the D810 has SD as well as CF has because it's only a semi pro camera.) Oh and did you have an actual point or were you just fan boying your camera or the camera you aspire too?
@sigmaandzeiss296
@sigmaandzeiss296 7 лет назад
Hahaha such utter nonsense. Nobody cares if you know some "armchair photographer" who found your review useful. Clearly you took my comment personally although I'm only stating a fact that the D810 does much better with CF than what the crappy buffer on the D750 does with SD that fills up after 2.2 embarrassing seconds lol. LOL 2.2 seconds and the buffer is full. Anybody who thinks that is great must be insane lol. Perhaps you have been into photography for like 2 years since you also downgraded the CF cards which have been used in every pro camera from Nikon at least for the past 10 years. And yes, now we're seeing a transition into XQD cards but so far only the D5 and the D500 have XQD without the option for CF. CF is getting too slow for sure and that's a fact. JFYI I shoot a D3S and 2 x D4S so I'm not "fanboying" anything here at all. Your crappy reply seems to indicate that it's you who are a sad little D750 fanboy who got his first full frame (the D750) for about a year ago lol. My point was only that CF cards are superior to SD and that's why Nikon have been using CF in all the pro bodies so far (now they are switching to XQD). No flagship pro camera made by Nikon has ever used SD cards. You can ask that from your local Nikon authorized camera shop lol. Your reply was so embarrassing that I don't even believe you own a D4. Anybody who owns a D4 wouldn't buy a crappy D750 with a shit buffer that fills up after 2.2 seconds lol. And then make videos on RU-vid trying to pretend the D750 is a badass camera lol.Anybody who uses a D4 professionally would have to be insane to get a shitty D750 with a shit buffer and a crippled buttons controls layout plus a number of other shortcomings such as max 1/4000s. lol. JFYI If I would have to choose between the D810 and the D750 I would for sure take the pro level D810. The D810 beats the crap out of the D750 in everything except built in wifi and the tilting screen. And it's a full time pro camera. The D750 also have the green little AUTO mode setting lol. So I guess that would make the D750 a fully enthusiast point and shoot DSLR camera for those who like point and shoot photography lol.I didn't even bother to read everything in your essay but you better think twice next time when someone gives you a little critique or feedback. Only a true D750 fanboy would make so much noise and trouble like you did lol. The only point I made was stating that CF cards are faster and you acted like a teenager who got bullied by the other boys who got better toys lol. Now sod off and make some more videos about the shit D750 lol. I'll be following you with this or another account :)

Notice how its going from 1 to 0? Your filling the buffer
@1337flite
@1337flite 3 года назад
Notice how I didn't make any claim that the buffer wasn't filling? In fact if you read the description you'll see where I said: "Note that in all cases, the intial burst is longer than the estimate when you half press the shutter. E.g. In 14bit FX the top LCD indicated 12 frames in the buffer but we got about 18 shots before slowing down." What is the intial estimate when you half press the shutter button? That's the camera's estimation of when the buffer fills. Why does the frame rate slow down? Because the buffer fills. What I said was the D750 can shoot continusously for 100 frames. And it can - as demonstrated. The D750 can continue to shoot continuously (at a lower rate than when there is space in the buffer) when the buffer fills, but still at a constant speed - hence "continuous" That was the point. Earlier models in roughly the same place in the Nikon DSLR line couldn't. Earlier cameras witg SD cards (e.g. EXPEED 3 based cameras) couldn't - and I think earlier SD cards probably couldn't have written the data even if the camera could have. What used to happen with cameras like the D7000 or the D600/D610 was, as soon as you filled the buffer the camera would stop, then start and stop then start, but at inconsistent speeds. E.g. it might pause for 3 seconds for one frame then 1 second for he next 2 frames, then 2 seconds for the next one etc etc. I.e. the IO subsystem of those earlier cameras was not able to maintain a constant write rate once the buffer filled. This changed with EXPEED 4 for both the D750 and the D810. The more constistent write speed also allowed the buffer to recover fasterm than the ealier models.
