... So put heaters in them to keep the lenses warm in winter! :)
(it only has to go a few degrees above zero... shouldn't take that much
power if it's on a time-limited thermostat)
Hence the: "Maybe the current generation have built-in heaters to combat this"
bit ;-) I don't know if they actually do that, at least not yet. I expect it
takes time to come up with a design (the easy bit) and then get it approved
for actual use (lots of testing and paperwork, no doubt)
