Customer Reviews

works!!
works on nikon d300; but not on nikon d700 too thick to go in to card slot

Works with Sony Alpha 300 with a microSD + SD Adapter
It works beautifully with a Kingston microSD card + microsd<->SD adapter.
So now basically I just leave the compactflash adapter (with the microSD<->SD adapter nestled inside) inside the camera permanently. And I just need to carry a load of thumbnail sized microSD cards.
Love it. Didn't buy this item from Amazon though.

Works great with a Canon 5D, but is a bit slow.
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.
