Maybe I should ask, where can a SD card fit where a CF can't? Or; how many SD cards do you want to store somewhere where CF cards won't fit?
AFAIC, a CF card is small enough. Why do you need something smaller? It not as they are the size of a VHS cassette and the SD card was the size of a 8mm cassette.
I do understand that most of the 'toy' cameras use SD cards and someone pointed out that the manufactures think this is a way of luring people into the DSLR market by using the same card format as their cheap sliver toy camera.
Frankly, spending another $50 or so on a new card or two shouldn't be a big deal since you are spending 10x that on the camera and lens(s).
As fragile as these SD cards are, I'm surprised there aren't more problem with them snaping in half or getting zapped with those exposed contacts.
Your thoughts? |

What's the deal about micro-SD cards? What's wrong with SD or even mini-SD cards?
I mean, was the size of a postage stamp not small enough? Now they have to make 2 gig cards the size of my little pinky's fingernail.
What gives... ???

For consumer level compact cameras, the smaller card allows them to be as small as possible. It's not as big a deal for SLR's, but I think the change is simply a matter of moving to the newer, more common standard. At the current dirt cheap price of flash memory, it's not a big deal anymore to have both.
I think the SD size is about as small as is practical. The Micro SD's are great for phones, but I would not want one of those in a device where I was constantly swapping it out.
I think there are enough formats now to hold us for a while. I noticed that Fuji and Olympus are starting to give up on the XD Picture Card and are now making their cameras with dual slots. I'll bet it was affecting sales.

AFAIK olympus still only uses Xd and will not switch(i believe it was a memo we got from olympus at work) they said something that there special panoramic software on the xd card is essential in function of the camera to the memory card. So they will not be switching. I believe they have a dual slot though on their dslr's.
But yes Fuji has made all their compact cameras with dual slots so they can take either the sd or xd.

Really poor comparision. Memory cards aren't road hogs & gas guzzlers. Try again.
I see after doing a little research that SD cards have DRM which AFAIC is a disadvantage. Something more to go wrong and has no useful purpose.
I also see XD cards have no built in controller which I assume helps to reduce size. Any comment here?

| From what i've heard SD is better in just about everyway when compared to CF. And it's used in pretty much everything except DSLRs. |

I have upgraded all my systems to where I don't use any cards anymore. All my data in all my devices Transfer wirelessly to the 10-TB storage system I had implanted in my brain. every 10 minutes, it connects via Satellite to Back up all the Data again to my Home planet.
It's actually an easy way to handle everything. |

ummm ... ok ... what's up with bite sized frosted mini-wheats? regular sized frosted mini-wheats fit in my mouth just fine?
better?

Actually, I see the OP's point. Memory may be cheaper now, but still, a 2GB high-speed card runs about $30. A couple of those adds up pretty quick, and that's money I'd rather spend on a new lens, flash, etc. So when you've got a collection of CF cards and suddenly the cameras switch over to SD - for no good reason - it is annoying.
And there is no good reason. CF cards are available in much larger sizes than SD can touch, for less cost. And it's not like they're that huge. In an ultra-compact P&S, I can see the point of using SD. But in a DSLR, the gain in size reduction just can't be that big. It's just another marketing gimmick to make us go out and buy new parts again.
I sold my S50 for a G9 and am going through this same thing right now. The S50 used CF; the G9 uses SD, so now I need a whole new set of cards. Really tweaks me...

Best thing about SD vs CF is that SD doesn't use pin contacts. There's always a worry, when inserting a CF card in a hurry, that you'll jam a pin and render the camera unusable. My Fuji P&S uses SD, and they never caused me a moment's trouble. My Canon, of course, uses CF, and while those have never caused me a moment's trouble either, I still do worry about those pins deep in my camera where i can't get at them to straighten them.

It was and mostly still is slower than CF cards. It was also more expensive than CF cards.
Other than at the higher ends of the DSLR market, the speed difference doesn't really matter.
The price/size relationship has been improving. |

There are certainly applications where size is really important. CF would be pretty much impossible to implement in most very small cameras. Even for smaller DSLRs, it can be a significant design penalty, when the total volume of the card and receiving connector is considered. Small size is a potential problem with loss of loose cards, however. I really prefer a physically larger format (like CF) where the card is a manageable size that won't be easily lost.
Use of the CF format incurs a penalty from a manufacturing cost perspective. The interconnect structure is expensive, both on the card and on the host. You therefore pay more for a product that uses CF than other formats, even if you pay less for the CF card itself.
The CF interconnect system is also mechanically more fragile than an array of pads/contacts. Bent pins in the camera are not that uncommon, especially where connectors are used that don't fully prevent reversed insertion.
Still, CF is the preferred format for very high capacities, because there is simply more space to mount the silicon and interconnect it. The read-write performance of CF also tends to lead the class, again because it's easier to design high-speed support electronics into a card where more space is available.

I've been using CF cards for years in various devices, and have never had a pin bent. I think the slots are designed pretty well, to make sure the card can only go in straight. The thought has occurred to me however, as I have many times had the unpleasant experience of legs on socketed eeproms for circuit boards getting bent. Now I can upgrade firmware with a CF card or flashing via a cable and I love it. |

The parallel data bus in CF cards vs SD's serial interface helps quite a bit too. |

My last two Oly cameras ...the C5050 and my DSLR both had dual slots and I love it. My evolt takes both CF and XD and is wonderful in a pinch and I don't have time to reach in my bag for another card. (and an added tip to OLY users...If you have two cards in the camera, the space between the CF and XD cards is just big enough to hold another XD card for quick access...since the card has a little lip it tends to sit just lower than the other cards...just don't forget about it and quickly open your card access door cause it isn't a tight fit at all and could drop out.) I just wish oly had made it easier to switch between cards, like maybe automatically or one button. |

I read an article on the switch Canon made to SD in some models that used to use CF and the reason Canon gave was that it enabled them to have more room inside the camera for the advanced electronics, dual processing chips and the like so they could keep the outside size and shape of the camera bodies consistent.
I'll see if I can find a link. This was a few weeks ago I read this. |

I wish that was true for the one that snapped in half when my wife was removing it from her Lumix camera, apparently it doesn't eject the card very far and when she tried to grab it it snapped...still can't get a reader to recognize it and from what she said it was full of pics. :( |
