Just curious as to what size, and speed of CF card do you use in your Canon 1D Mk IV?

Thanks in advance.

Generally a 16 or 32 GB, not the very latest speeds because the cam doesn't make use of that, but fast enough for quick downloads to the computer. Right now there's a Transcend 32 GB 400X in there.

16GB CF for RAW and 16GB SD for JPEG backup. Transcend 600X. (Carry backup for both, though I've never needed to switch during a football game or back to back basketball games.) Shooting HS sports. Buffer clearing time is the slow point in this arrangement not 600X card speed. Do have to say that the buffer clears quite fast, so I rarely miss a shot due to buffer or card speed.

Transcend 16gb 600X CF cards for RAW and 8gb Eye-Fi for small JPGs transferred directly to my iPad for reviewing. I haven't noticed any slow down apart from when the buffer fills up, but it clears very quickly. Transfer of RAW files direct from my 1D4 to my PC is very quick using that particular CF card.

I use the 16GB Sandisk Extreme CF's rated at 60mb/s. I've never had any issues with missing shots while clearing buffer or any data corruption yet. Work very well.

I use 32GB Sandisk Extremes -- 60MB/s will save you money and they're fast enough for me ... and I'm an unabashed "spray and pray" shooter.


If you want to download faster just invest in USB3 -- it's way cheaper.

Thanks everyone for the replies. Much appreciated.

Don't know if this has been posted yet, but it might be of some interest to those who shoot with the 1D4 or 5D Mk III:

It's about 1.5" x 1.5" I'd say, standard size

Currently using a 16GB UDMA 6 card rated at 60Mb/s. Might get a UDMA 7 when prices drop although there is a good rebate on the Lexar 1000x atm. Hmmm!

Check Rob Galbraith's database for CF and SD card speed. This is link for 1D IV

The RG recently updated CF/SD test for the 1DIV shows that the UDMA-7 Lexar 1000x do make a difference in the 1DIV. I'm currently shooting with the Transcend 16GB 600x because they were a sweet spot for price and performance back a couple years ago, at around $75 each, and are now around $50. With the current Lexar 1000x rebates, I'll probably pick up a 32GB two-pack, partly in anticipation of the 1DX.

64 CF Transcend for RAW and 16 SD Transcend for LJPG.

RAW is 4x the size of LJPG.

I did a test with my cards in the 1D4 a couple of weeks ago.

I got a few new cards so I did a new test. My new Transcend cards 400x which are UDMA 7 cards today are a lot faster than the UDMA 6 version of the 400x card. Both Transcend and Sandisk have updated their cards from UDMA 6 to 7 without saying anything. And the new cards that look the same except the 7 or the Video Performance Guarantee (VPG) pic.
It's 30 sec shooting with RAW in my Canon 1D4. All settings are the same of course. But this time I had the lens on MF and also the camera in M settings to get everything exactly the same. I will do the same test with a 1DX when I buy that body.
ISO 100
1/4000 sec
f/5,6
lens EF 24L
Gitzo tripod RRS head

Conclusion: UDMA 7 cards are improved a lot. And there is a huge speed increase when comparing them against the same older card with UDMA 6. Even when the makers have the same speed on the card.

Transcend 64GB UDMA 7 600x------ 133 shots in the 30 sec burst
Lexar 128GB UDMA 7 400x ---------- 118
Transcend 64GB UDMA 7 400x ---- 113
Sandisk 32GB Extreme Pro --------- 113
Transcend 32GB UDMA 7 400x----- 112
Transcend 64GB UDMA 6 400x ------ 82
Duracell 32GB 600x -------------- 79
Sandisk Extreme III 16GB--------- 75
A-Data 533x --------------------- 60
Transcend 32GB 133x ------------ 52
Transcend 16GB 133x------------- 46

Lars,

Hope you have stock in Transcend as they've done quite well by you

Your test data is fascinating. One question. With a given card say a Transcend 16GB CF labeled: UDMA 600x, is there away to determine what UDMA spec is employed? The cards are less than a year old, but I don't know how to determine what spec is in use.

Aside: It appears we have - at a minimum - 3 different ways of describing card speed: (1) UDMA specification, (2) the XXXx method (not sure what is being multiplied), and (3) speed in megabits per second, e.g. SanDisk's 30 or 60ms. We've managed to get a CIPA standard for comparing battery life and even an agreement on how to measure LCD's but seem unable to standardize on a card speed measurement. Frustrating.

@ Robert,

The latest Transcend cards say UDMA 7 on the card. Both the 400x and 600x cards. If not having that on the card, it's a UDMA 6 card. And it's a huge difference in speed between those.
And it's the same with the Sandisk cards. You could say the Sandisk Extreme Pro is a 600x card. And the Extreme a 400x card

Lars,

Thanks. I went rooting thru the Amazon offerings and noted that the same color, appearance, size, etc., Transcend in some cases says UDMA7 plus a little movie director "take" symbol. Other than that the card is identical to my UDMA6 card I'm currently shooting.

D*mn stupid way to market/label cards!

Thanks for the help,

Robert

Where can you buy the Transcend UDMA 7 400x CF cards?

On B&H's website, all they show is UDMA 6 400x and 600x CF cards.
