According to this link, the C7000 can use a 1 gig card:
What is the advantage of a 1 gig over two 512meg cards:
Usually the 1 gig will be priced lower than 2 512 cards.
The 1 gig card will hold twice as many photos.
That is about it.
Brand name has turned out to be a non-issue for almost all memory cards. They have to be made to a standard and they will all work.
Olympus and Fujifilm came up with the xD card.
And Sandisk is a trusted card maker.
I believe that Olympus may have a stitch feature that is only available if you use the Olympus brand of card.
A gimmick to sell more of their brand of cards.
This is pretty much of a non issue too, as there are plenty of software programs that can do stitching for panorama photos.
I just purchased the Olympus C-7000 which uses an xD memory card and I have a few questions about it. First, I presume that the C-7000 will hold a 1GB card - correct?
Second, are there any advantages to buying a 1GB card vs.a 512MB card? If so, what are they?
Third, is it necessary to use only an Olympus brand xD card, or will either Fujifilm and Scandisk or some other brand also be compatible with the C-7000 and work as well? Thanks.
