What have you just BOUGHT?

...I got this generic hot shoe mounted, waist level viewfinder, for my Ricoh GRiii, off of Mssr. Bezos’ website. The entire field of view is 28mm, and there are frame lines for 35 and 50 … I usually have the Ricoh in the 35mm crop mode. It works quite well in bright light, it’s intended use case. It’s also nice getting a waist-level perspective, difficult to do otherwise from a camera with no tilting screen and lacking a VF.

This looks handy enough to be useful... I ordered one. 🙂
I'm not expecting Leica level quality and optics; if the view is clear enough in decent light, it will serve the purpose.
