Video file attached shows buffer of 1D X stop after 36 frames using the fastest memory card on the planet as of today. I had to downsize the video file to 480x270 mpeg2 and compress it heavily to be allowed to upload it here with the file size limit of 4096KB. The Lexar Pro UDMA7 card is mine, I am using it on my 5D3. I brought the card with me to a photography show here in Norway where they had the 1DX. I put my Lexar UDMA7 Pro card into the 1DX and my friend filmed while I kept the trigger until the buffer was full.

This means Ron here:
http://www.ronmartblog.com/2011/10/hands-on-canon-eos-1d-x-lots-of-photos.html

is probably wrong, since I tested the 1DX with a faster card than him, at a later date than him,
meaning the camera at least should have the same or newer firmware than at the time of him testing.

I am trying to upload and attach a video I shot when testing the 1DX buffer, proving it can only handle 35 frames, but uploads does not seem to work on this forum.

Filetype I am trying to upload is mpg, did also try with flash (flv), still not working..

The one thing that dissapoints me with the 1DX is the buffer size and the number of RAW frames possible to store during a high burst.
The 35 frames takes only 3seconds, 3 !!!!! to fill the buffer..

Anyway, there seem to be something strange going on, since shooting m-RAW mode actually decreases the number of possible burts
 shots to 26, while shooting s-RAW mode increases the number to 39. I understand it takes some computing time to resize the RAW, but this will also happen while downsizine to s-RAW. Hence it is strange that the number of frames possible during m-RAW is "only" 26,
which is a ridicilously small number which you will reach within 1.5sec !!  Why could not Canon install a 3 x bigger buffer when the rest
of the camera is built for speed?? (shutter/cpu).  The D4 can shoot up to 3 times more frames than the 1DX.

I have tested the 1DX with the fastest memory card currently available on the planet (Lexar 128G 1000x Pro UDMA7 150/150MBps),
and the buffer was still full after 35frames continious shooting.

Too bad Canon!!

That seems to conflict with this report:

http://www.ronmartblog.com/2011/10/hands-on-canon-eos-1d-x-lots-of-photos.html

When I read about the 12fps performance of this camera I was excited – especially given the larger image size – but I was also worried as my 10fps performance of the 1D Mark III & IV has always been significantly limited by its puny buffer. In my early testing with what I was told was a slow CF card, I was able to get 52 full-size RAW frames in burst mode before the buffer started to stutter. That’s up from 30 in the 1D Mark IV, so that’s promising given the significantly larger file sizes. However, I would have really loved to have seen that number closer to 100 for RAW. RAM is pretty cheap, so I’m always frustrated there isn’t a way to add RAM or do something to overcome this limitation. With that gripe aside, the 52 RAW frames is going to be usable enough in most practical scenarios so this is a welcome relief. This also means that sRAW or JPEG only shooters will find themselves with an endless supply of buffer for sports shooting.

Indeed, and check Ole Salomonsen comments back then in that thread!!! (which he (Ron) called BS!! )

Looking at page 393, it looks like the 1Dx is going to use the same codec as the 5d3(same data-rate), so I doubt their will be any improvement in the video.  That's absurd for the amount of horsepower this thing has. Totally nerfed.

Agreed! Let's just hope the guys at Magic Lantern get things going fast on the 1DX. (1080p/60, 4K video, clean HDMI out)

Still kinda an expensive camera to buy to rely on and wait for Magic Lantern (or others) to enable higher video bitrate, and clean HDMI out!

Canon need to understand it does not help if they cripple the 1DX for features to prevent canibalizing their video department, as long as the competition gives us the features (Nikon=clean HDMI out) there is always a risk of some users jumping ship.

Probably not going to happen for Magic Lantern. They tried to get it working for the 7d which has dual Digic processors which was a problem for them. They have it booted on the 5d3, although it's so far from even having an Alpha release it'll probably be a year unless they can get someone devoted full time to develop on it. If they can eventually figure out multiple Digic cameras, then it may be possible to come to the 1DX, but it probably won't happen.

You are probably right. And the more I think about it, I am considering canceling my 1DX preorder since it IMO is simply not worth it given too few extra benefits compared to the 5D3. (weather sealing put aside). No noticable improvement in high ISO performance, DR or picture quality from what I can see from my own testing. And, in particular due to the dissapointingly low buffer of the 1DX you will in many cases not be fully able to utilize the shutter speed improvements on the 1DX over the 5D3.

And if Canon think I am gonna ruin myself with 15000 dollars to get clean HDMI out from the 1D C, they have to think twice. I know of other ways of getting what I want, even if it is drastic and expensive, it may still be cheaper than spending 15000 on the 1D C.

Hey let's hope ML at least get's things going for clean HDMI out on the 5D3, and maybe even short bursts of 4K video.

EOS Bodies / Re: 1DX sample RAW images

« on: May 22, 2012, 08:39:39 AM »

I have few but not from a final version. Canon allowed me to use one for 24hrs last month!

Yeah the Canon representatives kept saying that the final version would have much better images.

I simply do not believe that!

The hardware is finished (sadly since I was hoping for 3xlarger buffer, f/8 autofocus and, headphones out and clean HDMI out).
So only improvementes likely to be done is in software. And I don't need any hidden noise reduction to be applied as I would prefer to preserve details/sharpness and do NR in post myself.

It's a great camera, hey most likely the best DSLR in the world!! But still we want more?! Thats the way it should be!

I have LOT'S of RAW files from the 1DX, 5D3, D4, D800, D800E, I took them all myself during a photography stand here in Norway.
I have been trying to compare (in a non scientific way) shots done with all cameras of a similar scene, with different ISO's, and also underexposed down to EV -2 and lifting shadows after.

The 1DX is maybe 1/2 stop better than the 5D3. About same quality as D4.
The 1DX might be slightly better in the shadows than the 5D3, slight less banding.

The D800/D800E is impressive taking into account the huge resolution,
still nowhere close as being that much better than the 5D3 in the shadows as some tests say.

The 1DX (and the D4) is a pricy camera, but I think you pay for getting speed and AF, not just SNR/DR.

IMO all cameras are good on ISO/DR, and the differences are so small it makes little sense for anybody
to claim any camera is substantially better than another. IMO, at ISO25600 things are starting to get useless,
regardless of what camera you use (maybe at ISO12800 on D800).

So not a big difference between the 1DX and D4?  IS one of them better at high ISO or they are really the same?

Hard to tell as the lightning conditions changed as I switched from the D4 to the 1DX, also I missed a little on the focus with the D4, but I think they are pretty similar wrt SNR.

I did a second test shootout between the 1DX and the 5D3, with a fellow photographer, and we both feel the difference between the two in SNR/noise are almost not visible. Maybe, MAYBE 1/2 stop in favour of the 1DX. Don't expect miracles from the 1DX!! But I own the 5D3, and I am still going for the 1DX due to the speed. Still the buffer stops very quick even if I tried with the fastest memory card available on the planet (Lexar 128GB 1000x UDMA7 (150MBps/150MBps).

Makes absolutely NO SENSE with more megapixels than the 1DX on a FF video DSLR !
Maxium 8-9Megapixels would be sufficient for 4K video and would provide excellent
low light conditions! Totally strategic miss and WAY to expensive!!

I can understand some people demand higher megapixel count, but NOT on the 4K video DSLR,
totally wrong direction!

Also I why no RAW video? Writing simultaneous to two or more UDMA7 cards (300MBps) should be sufficient for that.  Like some other cameras from Panasonic.

Completely disappointing if these specs are right!

update: And looks like they are according to dpreview.

And since 18megapixels you have to crop down to APS-H (1.3x) to avoid extra cpu usage in downscaling, and then you can not use your 14mm fully, or your 24mm 1.4 !!!

Ask about file sizes (RAW) on 1DX, can not seem to find any info about it.

5D3 seem to be (RAW) 32MB-42MB..

And, as pointed by others (HDMI clean out, fixable by firmware?)

Lenses / Re: 14mm prime vs. 16-35mm zoom

« on: February 26, 2012, 02:07:43 AM »

I have used both the 14mm (II) and the 16-35 (II) and they are both below par on full frame due to average corner sharpness compared to eg. samyang 14mm and nikon 14-24.

On a crop APS-C camera as the 7D you might not see the softness in the corners, but it is a total waste of money to buy any of these lenses to use on a 7D.

Buy a Tokina 11-16, which is an excellent wide angle lens for the 7D, fast (2., and sharp edge-to-edge... The upcoming Tokina 11-16 2.8 II might be even better..

If you insist on buying a prime, I would save the cash and buy a samyang 14..

Third Party Manufacturers / Re: Nikon's D4 Officially Official

« on: January 06, 2012, 06:22:57 AM »

First, I know many of you don't care about video features in DSLR. But face it, it is clearly here to stay.
Please do not forget that filming with DSLR for real started with the 5D2, and a huge portion of the success
of the 5D2 is due to it's video capabilities. For me both still and video IS important, and I use my 2 x 5D2 maybe
just as much on it's video features as on it's still capabilities.

That being said, I have already pre ordered my 1DX several places to be sure I get it soon.

Resolution and speed between D4 and 1DX is not that different that it would matter for me, and probably not AF either.
BUT, assuming the D4 and 1DX performs comparable on ISO, the D4 could be a game changer in my opinion.

It could be a game changer because Nikon now has given consumers what they have begged Canon for now for years, which is UNCOMPRESSED VIDEO! Even if the 1DX offers less compressed video, it is still not uncompressed. The D4 can with this open up new creative possibilities never seen before. Even if the actual recording has to be done through an external device, the option is there, and those devices are not that expensive.

I really really hope this is something Canon is able to implement in the 1DX before releasing without major hardware modifications!
Otherwise I am tempted more than ever to switch to Nikon, sad to say, but if youre living out of photo/video, you have to have the equipment that gives you the edge on the competition.

Also the 1DX lacks the proper audio monitoring capabilites as the D4 has for movie shooters.

Now I know that Canon has officially announced the Canon Cinema DSLR 4K, which is exciting wrt resolution. But nothing mentioned yet on uncompressed/RAW video out on this camera. And even if it does get uncompressed video, it will cost me a lot to have to buy both.

Just my thoughts, we are all different, with different needs and preferences. For me it's more important to be able to do creative things to an affordable cost, or as low as possible, than to stick to a brand just for the cause of it.

Though, as many others in here, I am also a little suspicious about D4's native ISO up to "only" 12800, and then expandable up to 204.800. Especially with larger pixels than 1DX, even if just slightly.

Either there is a huge gap in what Canons and Nikons perception of what acceptable native ISO is,
or there really is a huge differnce between the D4 and the 1DX, time will tell.

So now we need to be able to compare RAW's from D4 and 1DX, and I think Canon now will be forced to release high ISO RAW files before the D4 hit the streets.

« on: November 03, 2011, 01:17:14 PM »

I have the SanDisk 128GB UDMA7 PRO card and it is working 100% on my 5D2, as well as my Wintec 64GB cards.

Write speed on the UDMA7 card is no faster than on the UDMA6 cards though, max 33MBps.
