Hi,

Having jumped in and ordered 5DmkII and 7D from Kerso, I'm now looking at memory cards.

Having always used Kingston or Sandisk I dont know what speed to buy :thinking:

Kingston list theres as 166x sandisk as 30/60Mbs

Can anyone tell me what kingston speed is eqivilant to the sandisk ones please?

Thanks
 
Thanks Scott, that helps, I've been wondering that to.
 
I can tell ya, got the new Sandisk Ultra in my comp as we speak, they claim on the card (genuine bought from warehouse express)

30mb/s 200x

These are the latest ultra version though to replace the (i belive discontinued) ultra 2's!

The 4gb is available from 7dayshop for £12.99 delivered each, and the 8gb for £19.99 delivered each :)

4gb

8gb

hope thats of some help to you!!
 
The new Sandisk Extreme cards are 60MB/s and UDMA - which as far as I know will enable you to get the best (speed wise) from your 2 new bodies.

Nice purchase by the way :thumbs:
 
I've been using this one from Kingston with my 5d Mk II with no problems at all with stills or video - very good value for money: 8GB for £14

really? seems very slow read\write speed :shrug:
 
I don't really understand the fuss about the memory cards. My cheapo 2+ year old MyMemory 8GB seems pretty fast and reliable. 4GB sandisk III has spent all time in the bag.
My point is the camera has a large enough buffer, and you will have to fill it up before you notice any slowdown. Do you shoot 8fps over 20 frames in one go? If yes then you need a fast one. Unless you are going to do video...
 
I've got 3 Sandisk 4GB 30 mb/sec and using the 7D i can manage about 2 seconds shooting uniterrupted at 8fps before the buffer starts cutting in and dictating how fast I can shoot. This isn't a major problem since the buffer will fully clear again in about 4/5 seconds but I'm still going to try and test the 60 + 90 mb/sec cards to see if they improve on that much.

P.S. 7D RAW files are ~30MB. I'm not sure the size of 5D2 files but I imagine they will be similar and probably a little larger.

It advertises writing at 20MB/sec - I find it does about 16 in reality. Given that the video requires about 6MB/sec (video is about 42 megabits per second) this is more than enough. I don't think I've shot a sequence of more than 8-9 continuous, so can't comment further on that.

That's interesting - 7D RAW files seem to be bigger than 5D MK II RAW files (which are usually in the 22-24MB range)... wonder why that is?
 
I tired those 133x Kingston 8gb cards with my 20D and I found them slow to clear the buffer. 30mb/s Sandisk were much better/ quicker.

But now I'm in the same boat as you - I just put a 2gb CF card in my 5D2 and it shows capacity as 54 photos!

Just what I was thinking.:D
