Photo Forum / Digital Photography / Digital Photo / May 2008Memory Cards
Many people (not only Canon users) use a point and shoot of sorts (including EVF Long Zooms and Compacts) as well as a DSLR. Many use the same brand. So it appears that Canon made a good decision to change the new Xsi from a CF card to an SD card. I am not sure but I do not think there is any advantage to a CF card and the SD is less costly. As long as there is not advantage I am wondering if Canon, on the new rev of new DSLR version, is going to change all DSLRs to the SD format. So far I think that would be a good idea.

There may be a feeling in some pro circles that CF is better simply because it is physically bigger. It may also be slightly ahead in capacity and speed. Though SD cards have, I believe, the better connection mechanism. For the non-pros, I think that SD is clearly the standard today. Tomorrow, who knows?

Even my Garmin 2610 GPS uses CF cards. So I'm happy. I think, because the speed and capacity of CF is always 1 step ahead of SD, you'll still see the upper end cameras be able to use CF. I don't consider the Rebel Xsi an upper end camera. Steve [] > My Canon S400 P&S uses CF cards and my D200 uses CF cards. Even my > Garmin 2610 GPS uses CF cards. So I'm happy. [] > Steve My Garmin GPSmap 60CSx uses microSD cards, which are tiny. Have you seen that size? I wouldn't want to drop one in a field of grass - impossible to find I would think! But it's nice that they fit into standard SD slots with a simple adapter for reading and writing. Cheers, David >[] >> My Canon S400 P&S uses CF cards and my D200 uses CF cards.

My Blackberry uses microSD cards also. I bought one with the adapter but never used the adapter. Steve >> [] >>> My Canon S400 P&S uses CF cards and my D200 uses CF cards.

I find that you need to be careful with the write-protect switch, which can be too easily set to read-only. With the GPS, I download the tracks, and upload a variety of maps. Uploading maps is much faster when writing the card directly, and the tracks come down in convenient daily chunks (as GPX files). I haven't yet tied this in with the camera, though.

I would expect that CF and SD cards use the same chips. Cannot tell about electrical contacts and handling which is also a matter of personal taste. Actually, I prefer SD since they seem to become kind of industry standard. virtuPIC -- Airspace V - international hangar flying! tools & toys at http://www.airspace-v.com/ggadgets >> I am not sure but I do not think there is any advantage to a CF card and >> the SD is less costly. [quoted text clipped - 7 lines] > >virtuPIC With an SD card, you don't have any pins to bend, as you do on a CF card reader. The questions I have concerns *wear leveling,* as the card storage areas can only be written to and read from, RELIABLY, a limited number of times. (IIRC it is 10K reads/writes or somesuch). So if the internal card controller (in the card itself) has Wear Leveling, this is a reason to use that particular card. I haven't yet found out if my SD card has this feature, but expect it would/does, for the price I paid for it.

Cordially, John Turco <jtur@concentric.net> > Actually, all modern memory cards incorporate wear levelling. Understood. Question: does anyone know of a software utility that is able to read the relevant wear information on a memory card to be able to report back how "Worn Out" a particular card is? Eg: 'your card has accumulated an average of 12,345 wear cycles'. -hh > > Actually, all modern memory cards incorporate wear levelling. > [quoted text clipped - 7 lines] > > -hh Hello, HH: Here's a couple of hits, on this topic: Wikipedia - Wear levelling <http://en.wikipedia.org/wiki/Wear_levelling> BiTMICRO Networks/Press Resourses: Flash SSDs - Inferior Technology or Closet Superstar? <http://www.bitmicro.com/press_resources_flash_ssd.php> By the way, when clicking on one of the links (entitled, "TrueFFS(R) Wear-Leveling Mechanism"), at the Wikipedia page, it took me to SanDisk <http://www.sandisk.com>, instead of the listed URL. This leads me to suspect that the flash manufacturers don't want such information to become freely available, to the general public!

In fact, I just upgraded my original Digital Rebel to an XSi. I use an 8GB SDHD card with it, which I bought for around $20 and it works fine. CF cards are okay, but in smaller format cameras, SDHD is a better choice because they use less physical space in the camera, which means the camera can be designed either smaller or have more electronic components in it. > I use an 8GB SDHD card with it, which > I bought for around $20 and it works fine. > > CF cards are okay, but in smaller format cameras, SDHD is a better > choice > SDHC, not "SDHD" > Many people (not only Canon users) use a point and shoot of sorts > (including EVF Long Zooms and Compacts) as well as a DSLR.

Two advantages to CF over SD that I can think of immediately: folks who have been doing more or less serious photography for some time already have a bunch of CF cards; and they are a little easier to handle - particularly for folks with big hands and older folks. >Two advantages to CF over SD that I can think of immediately: folks who >have been doing more or less serious photography for some time already >have a bunch of CF cards; and they are a little easier to handle - >particularly for folks with big hands and older folks. Major technical advantage: CF does not suffer from the same design limitations and the resulting backward compatibility isses as does SD: - early version of 1.x limited to 1GB - later versions of 1.x limited to 2GB - custom enhancements using 2kB blocks to overcome the 2GB limit often incompatible with other devices - SDHC (SD2.0) limited to 32GB at this time. Although the interface format could support up to 2TB there is no requirement for devices to support this at this time, probably triggering yet another round of 'buy a new card reader' when the standard is updated to more than 32GB. In short: there will be 5 different and not backward compatible versions of SD within just 10 years. CF on the other hand has supported up to 137GB right from its inception back in 1994 with any 15 year old device from back then still working with the most recent cards just fine. jue > Many people (not only Canon users) use a point and shoot of sorts > (including EVF Long Zooms and Compacts) as well as a DSLR.
