We are considering purchasing several of the new Sony DSC-R1 Digital
Cameras.  This camera has the "Sony Advanced Accessory Shoe" which
allows you to connect Sony Flashes and take advantage of full
integration between the camera and the flash.  The Sony Flashes that
are available are not powerful enough for our application of taking
group pictures of classes in schools.

Can you please let me know the names and model numbers of at least 5
non-Sony flashes that are compatible with the the camera.  The flashes
must be able to take full advantage of the shoe.  Please include links
to techincal specs for each flash.

Thanks!
