Works, but is very slow

Since SD cards (also fast and large) rapidly fall in price, while for comparable CF cards 3-4 times will be callers, so came just at the right adapter. A little slower than a CF card, he should have been already. That Extreme Pro SD cards that the promised 95MB / sec actually brings on this adapter to 5MB / sec will be thwarted, however, is already too much. Funny Erwiese have slower cards (one Class 10 and a Sandisk Extreme 45MB / sec I tested) delivered a better pace. With 14MB / sec Again, it's over.

That is worth while just for old and slow cameras with CF slot if you have lying around the same time many SD cards. Although I have a lot of SD card for other cameras, the pace was me for the DSLR but then too much. For the price of the adapter you now get even 8-16GB CF cards are much faster.

Can therefore only recommended for people who do not care speed (Full HD Video recording is probably not going to be reliable and continuous shooting Puzzle). I can not say anything about the long-term reliability due to lack of experience. Three stars because you could just need the adapter for undemanding applications thoroughly.
