Having just been made aware of the ridiculous price of a 'ThumbsUp' for grip-enhancing Leica cameras ( £140 dollarses! ) I thought I'd just make a Thing. You see, I naively thought people were getting their's for £25-ish and looked to see if it was feasible to put on my Pen, and if it came with an extra hotshoe-on-hotshoe bit. Oh no. Way too expensive. I then looked into making one for myself with a hotshoe ontop, since it occupies the real hotshoe in use. Too complicated for a Saturday evening, so I made a simple thing and just glued it on. Yes folks, careful file-shaping of surfaces and latex contact adhesive. I guess tomorrow will give it a workout and see if it stays on.
