Hello Guliano,

I have some good experience with the Logitech C615 and C920 FullHD 
webcams. Under Linux.
BUT:
With the limited bandwith of USB 2.0, it is not possible to transfer HD 
video with acceptable framerate, so these hd webcams have built-in h.264 
compression.
Under Linux, the v4l2 drivers can use this compression and offer the 
full resolution in PD/GEM.
Unfortunately, Apple has not implemented this compression feature into 
their crappy usb camera drivers, so you stick to good old standard 
definition on OSX.

cheers,
marian
