Can you enlighten on the best set up to obtain the 6fp/s ratio
I presume it slows down the rate if you choose Raw + backup to SD card? or Raw + Jpeg?

I am not sure how the MK3 works in this regard. If the setting involves writing to two different cards than you are bound by the slower of the two cards. UDMA 7 only applies to CF cards. So if I was to test sustained 6 fps on my MK3 I would try it with my UDMA 7 16GB Lexar card. If the images are 25MB in size it should be able to sustain 6 fps until the card is full (not that I would do that). But my guess is at the full resolution the MK3 RAW files will be much larger than 25MB. So it will likely go down to 5 fps.

From what I gather from this thread. The 5D3 does not support the fastest SD card spec, but does support the CF UDMA7. With the fastest CF card you can gain an extra 5 shots in high speed burst RAW> (18 shots over 13 for a slower UDMA6 card).

From the prices listed at B&H. I can buy a 16gb Lexar 400x UDMA6 card for $60, or the faster 600x card for $88.

There is a marginally better performance that you get from the Lexar 600x card, for a 46% bump in price. As this is only a $28 difference, I am tempted to pick up several of the better quality Lexar cards to replace the cheaper 8gb kingston cards I currently own from my 50D days.

What worries me though is the Lexar SD cards all show a min write speed of 10mb/s. And from the chart given above, you need a 20mb/s card. So none of the Lexar cards would meet spec. What is a good quality card for SD / video use?

Scandisk Ultra 30Mb Class 10 should do fine for HD Video. The SanDisk Extreme SDHC UHS-I 30Mb is a step up for HD Video and faster shot to shot performance. Then there is the Extreme Pro, but you don't need it unless you want to speed up your offload times to your computer.

I believe that 5diii dose not support UHS-1 type cards.

this is where is stops making sense. To get an SD card that will give the 20 MB/s or faster write, you need to support the UHS-1 standard. According to Sandisk, all the Class10 cards are rated at 10 MB/s write, and the UHS-1 cards are the ones that reach 30 MB/s and above.

So how can the 5D Mark iii even use the ALL-I compression on an SD card if no card that the camera will support can achieve the 20 MB/s specified?

From what I'm seeing in reports from others, the faster 600x CF cards are allowing a faster time to clear the buffer once you hit the 18 frames on a 3 second burst (6fps for 3 seconds). You can then burst again quicker than with slower cards so if this interests you the faster CF cards are needed. I shoot birds in flight and wildlife action so this will be important to me and sports shooters that are shooting RAW.

What I'm interested in is the 5D3's ability to utilize the UDMA7 card speeds vs. the UDMA6 cards and how fast a card is utilized 400x vs 600x vs 1000x. If someone had a Sandisk Extreme Pro 600x UDMA6 card and could compare it to the Transcend 600x UDMA7 card that would be interesting as well as a comparison to the Lexar 1000x UDMA7 card...???

  • If you want to shoot still photos while shooting a movie, you will need an even faster card.
:shock: This is even possible?

with the 7D, and I assume other cams aswell, it was possible however you loose a small bit of video whilst the picture is taken. I tried it once years ago so can't give you the absolute facts, however I believe the time loss from the video was ~1sec

The manual says up to 1 sec.

I think Lexar are the only ones with UDMA7 at the moment and they are the fastest at present.
