Can anyone tell me the fastest write speed theyve seen on a CF card yet? Ive been thoroughly irked after seeing one of Sony's Memory Stick Pro's hit 16Mbps...

I dont like it when the company that makes your camera also makes the best accessories; reminds me to much of the collusive wiles of uber-capitalism...

Anywho, along different lines, would anyone know where theres a chart showing the different storage values of different CF cards/storage devices? I mean in terms of how many photos at what megapixelage and quality...

16mbps is a problem for you?

Rob Galbraith's database of CF card performance for various cameras

As for translating storage capacity to number of photos, your best bet is to examine the file sizes of some typical images that you take, and do the math.

Cheers,

Funny thing is, Patch has taught me there's no absolute finite number for the amount of shots a CF card can hold. It all depends upon how much information is in each shot. A shot of a blank piece of white paper will use less memory than a shot of a bush. That's why your digital camera can show one shot left for two or three shots (I used to think I was going nuts when that happened.)

Hey yeah, Ive noticed that too! I only have a 256 card for my f828, so that holds what it says is the maximum of 76 shots, but Ive had instances when Ive gotten up to 150 or so shots on that same card! Even more when I use burst modes, of course... Sweet; Im not crazy either.

And whos Patch?

A 1 or a 0 would be the smallest amount of info..... so we could divide that into the card so def a limit.

It would probably look like my shot then.

I believe the cards reach 80x speed, and the hard drives hit 133x. Check to see if your camera can take advantage of the speed however. You may be fine with 4x cards at a much lower price.

I shoot Large Fine JPG and the camera thinks I can get 630 pics on one 2GB card, but I get closer to 770. No doubt because of the compression. I wonder, if I shot in RAW, would the number be the same all the time, no matter the subject?
