Originally posted by elsdad Does anyone know if the 645z will support the very fast SDXC cards rated UHS-II? The published specs on the camera only mention UHS-I . You would think that a sensor as large as 50 megs would benifit from the fastest cards available. This was taken from the San Disk site:
SanDisk Extreme PRO® SDHC™/SDXC™ UHS-II Memory Card
Available capacities: 16GB, 32GB, 64GB**
Performance/speed: Up to 280MB/s** read, Up to 250MB/s** write; U3 video recording speed**
The connector for UHS-II has a second row of pins, beyond that of UHS-I, which provides additional throughput. It appears that UHS-II cards will work in the Z, just not any faster than UHS-I cards. So, investing in UHS-II cards for the Z would be a waste of money.
Based on the reviews I've seen, it performs pretty well with just UHS-I.
