Digital cameras: Seeking Advice on Buying a Digital SLR
CF vs. SD
by ericasavaaree - 7/28/07 11:27 AM In reply to: CF v. SD memory cards by jimsbergThe one thing I still don't get, though, is why would one manufacturer want to use SD and another CF? Esp. with Canon, it uses SD in all of its lower end digital compact cameras, but CF in its SLRs. What advantage does one have over the other? Power? Size? Others?
Memory Cards
by Dan Filice - 7/28/07 11:03 PM In reply to: CF vs. SD by ericasavaareeDid you check out this website link I posted for you in my other email? http://www.steves-digicams.com/flash_memory.html It comes down to speed, basically. The SD cards are simply memory chips while the CF cards are actually micro-hard drives. They are MUCH faster than SD cards. On DSLR cameras, you have the option of taking RAW images, which are generally very large. It takes a longer time to write the image to the memory card as well as read them into the computer, so a faster memory card would be beneficial. And DSLR cameras have burst modes, so they would benefit from the lightning-fast read-write capability of the CF cards.
Vice versa?
by ericasavaaree - 7/29/07 12:31 AM In reply to: Memory Cards by Dan FiliceThe problem with that website is that the comparison is not listed there explicitly as a comparison. I used to work at Staples, and I saw high-speed SD cards, and not CF cards. So it was vice versa. So then I don't really see any diff. btwn SD and CF high-speed cards...

Scroll down a bit and there is a heading called "SD vs. CF. What's the difference?"
Interestingly is seems the major difference is storage capacity. It seems that SD cards are limited to 2GB. Speed doesn't seem to be an issue any longer.
Total Agreement
by trap49 - 7/26/07 9:03 AM In reply to: Seeking Advice on Buying a Digital SLR by ericasavaareeThe advice from hjfok was excellent, and I totally agree. Rather than buy a used, second-hand DSLR, you can get a great deal on "last year's model" from Nikon or Canon. Nikon has bumped up the resolution for the new D40X to 10MP, vs 6MP for the "old" D40. No one "needs" 10MP, unless you're shooting for National Geographic. The D40 can be had for much less than the D40X. Same goes for the Canon XT, which is the "old" model compared to the current XTi. Buy a new "old" model and you'll be getting the full mfr warranty for much less out-of-pocket cash.
