Need questions answered

I am looking to purchase a SanDisk 8GB CF card and I am just wondering if the Extreme III is enough for the 5D2 or should I go with the Extreme IV
The III is half the price even though there seems to be a $60 off mail in rebate on the IV but I think it is for US only.

I am also looking to get the Domke F-802 with the Domke FA-230 3-Compartment Insert and am wondering if it will hold the 5D2 upright with the 100-400 attached and another lens besides it. I was told that it will hold it but will it close comfortably or will the body stick out?

I've carried my 100-400 on a 20D in my F-802 no problem; likewise my 5D and 70-200 2.8 IS. As to the cards, depends on how much you shoot burst mode and fill the buffer. If you fill the buffer often, get the faster card. If you rarely or never do, then don't worry.

Excellent. I am going to go with that bag. As for the card I am mainly concerned if it will handle video rather then pictures.

Not sure on video - at HD rates you may need all the speed you can get.

I don't know if there's any sound basis for it, but I compare the video frame rate and resolution of a video clip to the camera's maximum frame rate in still shooting; if shooting still means moving more pixels I presume that a fast enough card for stills will be fast enough for video. Back of the envelope calculations say that 10 frames of HD video are about the same pixel count as 1 frame still at max. resolution, and the 5D II does better than 3 fps still, so it needs fast cards more for still than for video.

Is 8GB enough for those monster files?!?! You may want to consider 16 if you are doing a lot of RAW shooting...

Well I managed with my 4GB so far. I don`t shoot a crazy amount so I figured another 8GB plus my 4 will be enough. The extreme IV 16 gb is just way too expensive.
I can either go with the 8GB extreme IV or 16 GB extreme III

I think the III will be just fine, especially if the price difference is that big

Galbraith tests with 5DII show Extreme IV has transfer about 24 MB/sec vs. Extreme II transfer about 20 MB/sec for JPG files; similar benefits for RAW files

The newer Digic seems to finally make a difference between Extreme III and IV for the Canon cameras that use it.

If your 4 GB card is keeping up with the camera then the same class 8 GB, while they tend to be a bit slower, should be adequate. But the bigger the card, the slower. There aren't any video tests, but Rob Galbraith has tested a number of cards in the 5D II.
