Home > Consumer Reviews > SD-CF II : SD to CF Type II Adapter (Supports SDHC)

I purchased this adapter to utilize SD/SDHC cards in my various CompactFlash devices. And it works great!

I am using this adapter with a new 16gb A-Data SDHC card, and it works perfectly in all of my devices. Said devices include a Sandisk CF reader (attached to an Apple Mac running OS X 10.4.x), a Nikon D300 camera, and finally, a PlayStation 3. All of my devices "see" the full 16gb capacity of the SDHC card, and the read/write performance is outstanding.

The only caveat is that this adapter is a thicker "Type II" CompactFlash card, which may not be supported in some devices. (Thankfully, devices that only support "Type I" CF cards are rare.) Also, your CompactFlash device must support high-capacity CF cards -- those 4gb and greater -- if you wish to use SDHC cards 4gb and larger.

The bottom line? If, like me, you have been waiting for the arrival of a CF-to-SDHC adapter, your wait is over. Purchase this card, and enjoy utilizing your high-capacity SDHC cards in your CompactFlash devices!

I bought this so I could use SD cards in my Canon 40D DSLR. It fits into the card slot of the camera perfectly. The SD cards slide into the adapter smoothly and seat firmly. I've tested it with several SD and SDHC cards, all from different manufacturers, ranging in size from 256M to 4G. All were recognized by the camera, and formatted to the proper capacity. I shoot in RAW plus superfine large size JPG mode. Every shot writes about 20M to whatever card is the camera. I see no appreciable difference in the write speed between SD cards in this adapter, and CF cards.

Bought it together with a 16GB AData. Made sure to format card in card reader, not in the camera. Works flawlessly. Is a bit slow:

For 4 shots taken with a Canon 5D in RAW+Large_JPEG.

SANDISK EXTREME IV 4GB - 9 Seconds
SANDISK EXTREME II 2GB - 12 Seconds
ADATA 16GB - 14 Seconds
Adapter + ADATA 16GB SD - 18 Seconds

Note that in my card readed, the Sandisk IV and the AData SD are tied for write speed at ca. 10MB/sec. So, it is most likely the adapter slowing it down. In the adapter, on the computer, the AData writes at 3.9MB/sec, which coincides with the time taken by the 5D, as 4 photographs at 20MB a piece ~= 80MB. At 4MB/sec, that is ~20seconds, which is the observed time to record 4 shots on the 5D.

So, in summary, good for travel (Better to have a slightly slower card that my Laptop and PDA can read w/out any external accessories, than to have a faster card).

Basically, for the money, the adapter is great, UNLESS you do weddings or sports professionally, and routinely max out the buffer on your camera, then it is not for you.

this adapter works fine. i have a sony alpha digital SLR and it works great. the descriptions don't say if the SD card fits all the way into the adapter... it DOES. supposedly this card works with larger/faster SD cards, so i figure it was worth 5.00 more than the other brand to get this capability. i can download files from the SD card much faster than CF cards. also, SD cards are smaller and cheaper than CF cards.

I purchased this product along with the Eye-Fi home. Followed all of the instructions for the Eye-Fi, had to change my wireless network security option to get the card on the network & registered (used WPA-PSK, TPIK). The Eye-Fi fit well into the adapter and similarly the adapter with Eye-Fi fit well into my 20D. Turned on the camera and a CF error appeared.

A link to a site Photojojo Blog recommended to reformat the card, so I did. Everything works well, camera takes photos and shortly after the Eye-Fi transfers the image(s) to a folder on my computer all wirelessly. Note that you will need a wireless network, will not work Eye-Fi to Computer directly (ad-hoc mode). Small price to pay but it sure beats the bulkier wireless Canon option for about $1000.00.

Only thing missing is a Slide Show software that while running will display images from a folder that is being loaded wirelessly from Eye-Fi. Looking at Able Photo Slide Show V2.3 for that.
