4GB is not available anywhere here, neither is 2GB. And the prices I see are still above CF. And then there's the whole speed issue...Few manufacturers speed label their SD cards....

Canon goes SD

You are behind then. 4 gb from Pana at CES. Prices are above CF - wasn't disputing that but with an incredibel hardware base for SD now (phones, PDA's, vid cams, mp3 players etc) the rice will be dropping dramatically and has done.
Every one of my SD cards is speed specced (now have 6 of them)

Why would SD be a lot faster? It's using the same flash memory, just wrapped up in a different package.thats a plus for 8fps DSLR's ....
aside from that I like CF
The SD/MMC/xD/Smartmedia formats are all basically pretty similar to one another in most respects other than the physical layout. They are very, very simple interfaces to raw flash memory circuits.
The main difference with CompactFlash is that the cards include much of the control circuitry required to access the card, while the other card types require such circuitry in the device itself.
A particular combination of card and device might be faster than another combination, but I don't think that based on such results, you can draw any conclusions in general about that type memory card being faster.

Size and power consumption is lower
Agree that the speed diff is negligble and few if any cameras can make of speed differences anyway.
The real issue for me though is the SD cards fit in more devices and all I need is my CF adaptor and it is also fits CF devices. Can't do that with CF

It is a sad day for my collection of CF memory cards. When I buy another digital camera two to three years from now, the type of memory card that it uses will be a factor in buying.

I found it irritating that my Leica Digilux used SD. When Leica announced the digital back for the R9 and the specs said it would take SD rather than Compact Flash, I figured there was something going on. In one of the reviews of the digital back a Leica technician said that SD would surpass CF this summer in speed, size, and cost, and it was more secure from the start.

Announced, yes, but who has them in stores? And are the speed ratings equivalent?
In, say a Canon 10D you'll notice a big difference with a fast and a slow CF card. ( see http://www.robgalbraith.com/bins/multi_page.asp?cid=6007 )
The fastest cards use a different memory cell structure, which requires more transistors but can transfer faster. There are also different ways of interfacing to the data which can be optimized, again costing some IC area and design time. I don't really think SD has gotten to that point yet...The need hasn't really been there.

but it (all those CF cards) won't do you any good since in 3 years we'll have 50 megapixels and you're cards will only hold 10 pictures;-) plus the pins will be worn out/bent by then.
My turnover is 5 years - yes, I make them last that long. My current camera is the Optio 450 and I expect it to last me at least 5 years.
My PC is coming up 5 years, replacement next year. Still does all I need.

I was having a little trouble finding speeds of the two technologies, but this page was interesting:
http://www.nutrend.com/app/search.asp?submit=manufactory&catalog=68&manufactory=1403
The CF cards were around 2MB/s write 3 MB/s read (for the faster ones, they dipped down to 1.5MB/s for some models). The SD card was about that much, but a "Pro" card listed as 10MB/s read and write - quite a bit faster.
But those were all Simpletech cards. Looking at a page on the Lexar 40x card, I find this:
http://www.usbflashstore.com/le40xprsecof.html
Which claims about 6MB/s. So, SD can be a fair amout faster. Humerously on the top page the pro SD card was $5 cheaper than the slower SD card!
The help on burst writes is nice, but I also think consumers would like the faster reads. I still like the CF form factor better though.

I could see the surpassing in speed and size argument, but one thing I have to wonder is why they even bring up security? What does security even mean when I'm capturing my own images? The security aspect was intended all along for digtal music (where it's a non-starter as a feature) and is just baggage for all other needs, that's one reason I'm reluctant to support the format since I hate paying for extra things I find useless.
It's hard to argue with faster and cheaper though. I do have to wonder if some other format will come along before CF is entireley dethroned. I'm holding on to CF as long as is practical (as in, if I buy a dual-mode camera I'll still probably use CF for a while). I wouldn't let it dominate the choice of camera I buy though it certainly would factor in cost-wise.

Why do you like the CF form factor ?
Advantages ?
I use SD and CF but am moving toward SD because I can use it in other devices and just use my CF adaptor so I can use SD's in my CF devices.

I read that you use SD cards with an CF adaptor. Does this mean that you can use SD cards in an device (also digital camera's) that actually uses CF cards. And does this work good? Is here no loss of speed or whatsoever.
If this is so, where can I buy those adaptors, and what do they cost?
Thanks for your reply.

Yes, there are hundreds of them. Range in price from a few dollars on Ebay to about $30 full retail. They have been out for a few years now. See link below for example

No speed loss, SD actually faster.
Just make sure you buy one that has the same dimensions as a CF card. some are larger and will require the Cf slot to remain open - yuck

Sounds to good to be true. Then I only have to buy SD cards without worrying wich direction the market will go...!!
