Canon has always used CF cards for its dSLR line, this has not changed since the introduction of its first dSLR. But in its compact point and shoot line, Canon has changed to SD cards. I suppose part of the reason is SD is smaller, therefore more suited to a compact camera.

But I read somewhere that SD's are faster than CF in general, and they are cheaper than CF. Is there an advantage to CF?

For one you can switch body(ies) more easily with CF...

Unless you want miniaturization, CF is already too small to handle!!! :-)
BTW CF can be either 8/16 bit wide, SD is only a nibble -> the speed you're seeing is camera dependent not the theoretical speed which can still be improved

Compact Flash have had bigger capacities but sd is catching up. SD has no pins to worry about.

8GB solid state CFs (not microdrives) are commonly available... for SD largest seems to be 2GB.


And considering speed, 66MB/s speed has been already specified in CF standards and signalling/interface/bus of CF is same as PCMCIA ATA so increasing speed even more could be easy. (latest PC Parallel-ATA HDs used ATA133)

Commonly available for a price...around $700 or more. This size is really only needed for professional shooting needs.

I wouldn't choose a camera based on memory. Most folks would not notice any differences between SD or CF cards. Speed isn't even that important for the typical user, as the bottleneck is typically the camera, not the card. The lens, ease of use and image quality are far more important than the type of memory used.

SD Cards are now commonly available up to 32 GB.

A 32 GB Transcend model is going for $44.

A 32 GB Lexar model from their Professional Line at 133x write speed is now $70 from Adorama thru amazon, although the list price is $260.

http://www.amazon.com/Lexar-32GB-Pro...0138099&sr=8-4

The 133x claims a 20MB/s sustained write speed. This is also rated as a Class 10.

In CF, Lexar now has a 600x card. It's currently available at B&H for $240. It comes with a guaranteed 90 MB/s sustained write speed.

All that said, that is all technical specification stuff. Are tech specs the only thing to be concerned with, or are there other factors which determine which type of card is better?

A lot has changed in the five and half years since this thread was started but one thing is still certain, if your camera only takes CF cards then CF is superior and vice versa!

It really is a horse a piece at this time which is better. I have two D200's that use CF cards. The rest SD. I found a place that sells CF cards that actually hold a SD card. This will make downloading to my Netbook/portable hard drive a snap.

The fastest CF cards are faster than the fastest SD cards. Also, for reputable brands, the cost per gigabyte is generally slightly lower for CF Cards than or SD Cards.

This hasn't actually changed in years.
