Due to many contradictory recessions also to the CF-SD adapters other providers ichs halt risked times. The Adapter SD to CF CSL is completely ok. Tested in a Canon EOS 20D with a Kingston Micro SDHC Class4 8GB (type SDC4 / 8GB; 31525-001.A00LF) in the Micro SD adapter. Have made continuous shooting until the camera exposes. The buffer empty then takes about 10% longer than with Sandisk CF Extreme III 2GB ner On the PC with Card Reader Hama 1000 1 read SD card ca 20 MB and write about 9MB / sec. In SD to CF adapter are read 22MB and 9MB write again. Unfortunately I had no SD Class10 at hand. So I mean, that's fast enough and therefore a viable thing to SD cards instead of CFs to use. In newer camera models it will certainly be the bottleneck. For my purposes, but perfectly adequate.
