Description

I'd like to show you my new dewcap / lens hood USB heater for my favorite Samyang 135mm lens, of course a DIY device :-)

It consists of a self-adhesive heating foil which is connected to a USB hub:

This item fits perfectly into the inner side of the Samyang sun hood as it's only 4 millimeters wide and the length matches just the circumference of the hood.

The heating power is 3W at 5V which is quite sufficient for the lots of Danube fog here at my lovely garden :-)
