Hi Neil,

The optiMOS is a very nice camera, it does have the rolling shutter, QE is
about 55%  but it still runs the 100 fps at full res and is compatible with
many of the current software packages ;-)

The sCMOS cameras that use the USB 3.0 are not going to run as fast with
the USB restriction. The pco cameras run at 40 fps but I believe the
Hamamatsu cameras only do 30 fps. Correct me if I am mistaken..
