I have recently ordered a Canon 10D, my first digital camera. Searching the web sites, including Digital Camera Review (which has a very old comparison), I have found it almost impossible to get a clear picture of which compact flash cards I should purchase. Since I'll probably be shooting in RAW mode, I assume I should get at least a 512 MB or a 1 Gig card. But, which manufacturer. From what I've read, there seems to be little relationship between cost and quality. Also, it seems that cards seem to work differently with each camera they are used with. Lexar and Sandisk seem to be the biggest names. Vikings cost less and are well rated on some cameras. Pretecs, according to Digital Camera Review, works well with Canon D30s, but I can't find where they are sold in this country. I'd appreciate information on this as well as recomendations.
