CF Cards

[brutal]

What is the largest CF card that you have used in your A40. Someone on the Powershot-A forum indicated that 512mb was max. Just curious, I want to buy a large CF in the near future and stop using the 8mb and 16mb cards i have.

you didnt say anything so im kinda confused, Microdrives are type 2 and the canon only has a type 1 card slot. Im not sure how those would work

[Conk]

I had no idea that they were type 2. Sorry bout that.
The largest cf card I'm aware of is 512 megs.

oh I understand now.

Do you know, first hand, that a 512meg CF will work with a A40? the manual states 128megs but thats pretty small.

I can't see any reason why not. I could never see myself using a card of that size. Personally I could never fill a card with that many pictures. If you refer to the cf card table in your manual you'll see that that would be 500 large resolution photo's at superfine compression. I do know one thing and that is picture quality degrades a certain amount the longer it is left on the medium. I don't know how much or how long it is before it does though. I just like to get my pics downloaded asap.

Interesting ... as all compact flash cards are solid state devices and Microdrives utilise hard drive technology I am suprised at this statement. Can you let me know where you found this out so I can follow it up please ? I do tend to leave quite a few images on my microdrive as a backup when I am processing through them on my PC. Perhaps I shouldn't ?

The nice thing about larger cards is that you can take longer movies. You can take 400 1600x1200 at SF and not worry if you find a new killer suject and want to shoot 40 pictures.


Not having 10 years of continuous picture taking, I tend to try differant exposures, differant shutter speeds and so forth trying to get the perfect image.

I feel like I shot myself in the foot. I never even thought of the movie mode on the camera. As far as my statement about the files degrading when left on medium I should have been more clear. I was referring to cf cards not microdrives.

Picture quality doesn't degrade when images are left on a CF card or any other medium. Either your digital image will remain in its original state and quality, or the data will degrade such that you cannot open the image without repairing it. This is data loss, not image degradation.

Solid state memory types such as CompactFlash are actually some of the more reliable storage mediums in that regard.

As for Type I CF cards, I recall hearing that 1Gb Type I cards will arrive this fall.

I suppose I stand corrected. Thanx for the info Rustle.

No prob. Hope I didn't come off snobbish, and if I did, I blame the Ontario humidity.

Oh wait, it's not humid right now...
