CF dying?
Seems more and more DSLR manufacturers are switching to SD cards...

... Seems more and more DSLR manufacturers are switching to SD cards... My understanding is that CompactFlash requires more on-chip functionality and a more expensive physical interface (i.e. more pins and real pins rather than just connection strips.) It's also physically bigger. It all adds up to more cost. See: http://en.wikipedia.org/wiki/Comparison_of_memory_cards The bibliography at the bottom of the page has links to the full hardware/software specifications for many of the card technologies.

My first dcams were Sony (S85 and F707) which use the far superior memory stick; I've always thought the pins that CF uses are a disaster asking to happen. A bit of dust on the connector, and your camera needs a trip to the mfr. I've seen lots of bent pins in that sort of connector in the past. So maybe this is good news. (Our CEO just bought a portable DVD player, and it has an SD card slot, so it does seem that SD is winning.) -- David J. Littleboy Tokyo, Japan |

I get the impression that CF is now a niche product - restricted to higher end, so-called "professional" DSLRs. Just be thankful that it's not micro-SD which has won! Too many lost cards then.

I just bought the Canon 50d, and I was surprised to see that it still takes compact flash. CF cards are the perfect size for us older folks with fumble fingers. SD cards are pushing the limit, and those damn microSD things (my cellphone uses them) are flat-out ridiculous. There's no doubt that we could have memory cards in even smaller sizes, but the limiting factor is and always will be the human hand. dwight |

CF cards are very bad with connections. I had two readers of which a few pins were broken: toss and throw away. Much to expensive too compared with SD cards. -- --- Bertram Paul |

I never had problems with the pins on either the camera, or card reader. The key is not to force anything. Also, if the camera/card reader is properly designed, it would be impossible to insert the card improperly. The only other reason pins get damaged is foreign matter in the slot. I now have a camera (and other devices) with SD card slots, and aside from the smaller size of the SD card (which I don't see as an advantage), they work just as well. |

I get the impression that CF is now a niche product - restricted to higher end, so-called "professional" DSLRs. On the other hand the SD consortium made some other very foolish design decisions. Remember that SD is limited to 2GB and SDHC to 32GB. As card capacity is quickly approaching that limit we are in for another round of "HELP, my card reader can't read my SD card", just 4 years after the previous war of confusion. The brand new SDXC finally has some leeway with 2TB (maybe they got smart finally?), but by spec it uses the proprietary exFAT, which means you need to run a new Windows if you want to read what your camera wrote. Maybe there will be a new exFAT drivers for Windows XP, maybe ther won't. Mac users will probably be fine, too, because for sure Apple is going to licence exFAT. But users of older OS's or free OS's will be left in the dark unless someone manages to illegally reverse engineer the exFAT format. CF didn't and doesn't have those problems. It is 6 years older than SD (CF was introduced in 1994) and was designed for 137GB capacity right from the start, so the original design will be good for maybe another 3-5 years for a total live span of 20 years. Compare that with SD, which had to be updated with a non-compatible design change twice already after an average of just 4 years. I wonder who is running the SD consortium. Must be marketing and sales, because no engineer could possibly design a specification with a live limit of 4 years. Other limitiations of SD like proprietary interface affects mostly system designers (embedded systems, card reader manufacturers, ...) and much less the photographing public. jue |
