Someone asked for the size of the " foot" if Jon have the same thumb nail size as i have, it cant be more than 3 - 4 Sq CM or so, i assume at least half of the size of the sticky pad for the current main units, probably even as small as the sticky pad for the current remote cameras, and those are about 46 x 21 mm.
Sadly i dont have any sticky pads for the K2S cameras to compare with, but from memory i think those are 30 x 12 mm, so indeed smaller.
To me it actually also look as if the "foot" for the new cameras are plenty large to carry the weight i assume the camera have, and what ever little torsional stress the USB wire might have on the camera depending on how it is installed.
TBH yesterday i noticed one of my K2S cameras was half way loose on the glass, due to its fixed wire and the way i have the wire routed from the camera, so one could maybe argue the K2S have too small mounts, at least if you like me go very creative with the install.
But if the wire come off the K2S camera it is probably fine, but it do come strait off the end of the camera, and it is not super rigid.
I have this pic of the K2S beside the DC rear camera, maybe we could get a pic of the new cameras VS the same old rear camera housing.
As this pic of the K2S units also prove i think if you assume the shape around the lens are about the same size, then on the K2S i see no way to install a CPL filter unless it is on a sloped windscreen, on my side glass or rear glass that are almost vertical and flat, a CPL filter would have to be perfectly flat too otherwise there is no room for it when the camera are angled horizontal on a flat side or rear glass.
I dont think there even is a CPL filter option for the K2S cameras, they are simply too small for that.
I am going to chillax until i have the camera or see more tangible photos from other hands, And then deal with what it is.
