NX-1 15FPS?

If fps is critical, I assume you're shooting moving subjects (sports and whatnot). To me, the fps might not be your biggest issue with the NX1. Is it focusing and metering the way you want it to in your high fps shoots? Many would get rid of the NX1 for a lot of reasons, but slow burst speed would not be the prime reason for most. But, you're welcome to spend $2-3k more for a high-end Nikon or Canon but then you're back into DSLR and you're not going to tolerate the loss of EVF view or VF display during burst shooting

Did I say ending the thread and deleting the NX-1, may be lying on both counts. I got the NX-1 to shoot manual focus and use my Canon & Nikon glass and with focus peaking and the cameras best in class EVF, I'd rate the NX-1 as best manual focus camera on the market. And Samsung's 15 FPS claim makes the NX-1 trump anything out there. So with me not being able to yank 15FPS out of their claim, I'm annoyed. Now I can't stand next to my buddy with his Canon 1Dx/800mm and me with my NX-1/400mm Canon and say "my bird is as big as your bird and I got more of them", I guess I could lie...he wouldn't know. I would like to see someones 1st and 15th photos of a one second burst with exif data to prove Samsung's not lying.

As others said, it may be impossible to test the way you do. You should start firing exactly at the beginning of a second and perhaps the exif records the time when the image is saved onto the sd.

There are other methods to test, namely taking snapshots of a stopwatch recording milliseconds.

Everyone else who has measured it doesn't seem to be having a problem, so I'm going with your methodology being wrong.

It would not be the first time a product manufacturer embellished a bit, or used faulty testing methods to gather numbers and results. Maybe the 15 fps is on the day following the 3rd full moon, following April 1 and that was missed in the disclaimer. It's still a good camera, that may be a great camera if they tweak it a bit more and don't stop fine-tuning it.

I suspect it will be a 3rd party developer (think Magic Lantern) who gets the maximum horsepower out of the camera ... perhaps by the end of 2015?

I do suggest reading this as the answer to your question is in side and documented in detail.

There is secondary issues with what you are asking. The data on the card may very well be the time the file was written not the time the image was taken. As such if the Camera is writing at 11 images in JPG a second and shooting a 15... well that would be why the buffer fills up. The Seconds may also round.

Being has I just took a series of shots have shots that start at 32 seconds and shots in 34 seconds but no shots in 33 seconds... it is safe to say the data is the write data or the data is rounding.

Again if you do the same test as everyone else you should see it clearly.

Put in JPG (to get maximum buffer length) shoot with a stop watch (like an iPhone) and start shooting and stop after 3 seconds.. count the number of files. (in the way I demonstrated earlier) you will see 15 frames per second or very close to it.

The manner you are doing it creates an assumption the the exact hundredth or thousands of a second is recorded and tagged on the file, rather than the time the file is actually written to the card.

To test this I took a 3 second burst (3.26 at the stop of the clock) I took 46 files that is 14.11 FPS allowing for a delay between my reaction time of release and stopping the clock we are well with in the margin of error for 15 FPS. We know that it was no more than 3.26 seconds though. Thus the time stamp if your method is correct should indicate no more than 3.26 second between images. However if I am right and it is write time not shot time that you are seeing than it would be more then 4 seconds. The group started on the 22nd second of a minute and the shots ended on the 26th second of a minute. Which is sadly inconclusive. By it self.

So I looked deeper 4 photos were at the 22nd second. The rest between the 23rd and 26th seconds. Which falls inside the 3.26 seconds range but isn't for sure. So I went further. 11 files are written in the 23rd second. 10 in the 24th, 11 in the 25th, and 10 in the 26th second.

What this tells us is that even though I took 46 photos in no more than 3.26 seconds. Which at worse is 14.1 FPS The Camera more than 4 seconds to write those files and is only writing 10-11 files a second to my card.

As such this confirms that the time stamp is the time written not the time captured.

I hope this helps clear this up for you. The NX1 is fully capable of shooting at 15FPS as has been demonstrated in my previous post.

Not having found the magic combinations to get 15FPS, I need someone to shoot at 15FPS and post their 1st and 15th shot of the burst with exif data confirming the one second time stamp. The NX-1 I have appears to be incapable of 15FPS.

It would me nice if you posted pictures first (with exif), as you are the one requesting help.

I assure you, if the NX1 did not shoot 15fps, I would have already returned it!

the OP has demanded that we prove to him that Samsung NX1 can shooot at15 fps and we must comply. In this age on entitlement, what one wants one get or else one will throw a hissy fit.

O.K. I got a headache on this one, but I think I got it. The time stamp is from the card. So anyone who shoots at 15FPS when downloaded to the pc the exif data will show 11 FPS. Which means yours and others in this post would show the same. Darn, I was starting to think that the Chinese second was 11/15ths of the 15/15ths American second.

Let me add to that...the camera shoots at 15/15 per second but the card records at 11 of the 15 per second that shows in the exif data. Which means any exif data of a 15FPS burst would show 11FPS.

Use a voice recorder. Turn it on, fire off a burst for about 2 or 3 seconds (ensuring you have drive mode set to continuous 15fps and not 12fps). Import the audio file into a video editor and using the peaks from the shutter sound, count the fps on the timeline that occur in one second.

There are plenty of examples on the internet of the 15fps so why you want to claim that Samsung "made the number up" or "lied" makes little sense. You either have a camera with a faulty shutter or your timing method is faulty. I personally don't notice the difference between 11fps and 15fps and have mine set to 8fps. 15 is just complete overkill for what I do, heck 12fps is overkill for me, but I can see how 15fps can be important to some people shooting sports or wildlife where action can be unpredictable and fps count.

Best of luck.

It will be the same at most frame rates.

But yes the camera is shooting at 15fps but can only write to the SD card at 10-11 Frames a second (or less depending on the card speed or the camera's hardwiring)


I'm assuming it writes slower in RAW which is why you only get about 1.5 seconds at 15fps.





in Jpg at 8FPS you can shoot until the card fills up.

We figured out that doesn't always work sadly in older threads.. the shutter works in a odd way it seems we often counted fewer than 15 shutter sounds, but when you count the files on the card you had 15FPS. Not sure why this is. It should work most of the time but there has been documented cases where it wasn't fully accurate.

Yes. As has been pointed out to you on a number of occasions, the correct way to measure frames per second is to set your camera to manual focus and a fast shutter speed then photograph a watch with a millisecond display and count the number of milliseconds per shot.

O.K. I'm on board. My relying on the exif data time stamp was wrong, the NX-1's 15FPS appears to be truth and not fiction. I would also conclude that no card exists that can write data at 15FPS. Thanks for everyone's help.

As for jpg, some cards would exist, able to write at such data rates, but the i/o interface in nx1 is not able to go over 60mb/sec. Very poor performance compared to many competitors, despite the uhs-ii spec.

Ya that isn't so much the card but possibly the hardware. I believe the 7DMkII writes slower.

Nope, it's actually twice as fast with cf card and about 15% faster when using sd.

actually no.
The NX1 with a Samung Pro 32GB card (a card I have) gets 84 RAW in 30 Seconds. I got 98. Shooting at 10FPS (which is like to like)

The NX1 has no CF... so why would I compare NX2's write speed to it? There is no reason what so ever to suggest that. CF is faster. I was obvious to any reasonable person referring to SD. The NX1 Writes faster, getting more files with a equal or larger average RAW file.


Of course the firmware has been updated, and I don't know the methodology they used. In more cases at 10FPS I've heard the NX1 writes faster. As the files sizes aren't equal. Particularly has this thread shows the NX1 averages no less than 10JPG files written to a card a second with the files being between 10-12MB each... Which shows the Write speed is double that than they claim on the site.

So this is wrong, for you?
