The A77 complains "With this memory card is no image recordings ... possible". Acknowledged to this gripe, you can still work with the map. With high-speed with after 1 second with 12 shots a 24M pixels and the buffer is full, the camera shoveling forever on the map. Presumably, the camera detects the card incorrectly.
The A700 will provide their service without complaint. The stocked card must always be formatted only (!!!) in the camera, otherwise is almost nothing. The A700 announces accommodate 4770 RAW files - enough for a normal holiday. The speed is very good. Subjectively faster than my CF card with 45MByte / Sec. I have not measured - The internal RAID 0 division doubles the theoretical speed. Should I keep the A700, the card gets there its regular place.
The microSDHC I bought with adapter, this would therefore fit into the A77, residual risk under 7 Euro.
