So there is virtualy no difference apart from that the manufacturer has more flexibility designing the mouse.
There were two different lens magnification offerings for the 3305. The Kinzu and Kana used the 3305, but the lens was different.

I would guess it's more like the G100S than Logitech's SROM.
I'm not sure if custom SROMs are property of the customer or under exclusivity contract periods like the sensor is.Edited by popups - 10/29/15 at 12:41am
