I don't know who Zeno Felkl is. All I know is his blog, Classicameras, on blogspot is gorgeous.
What makes it work is the elegant documentation of the old cameras which the site features and the very plaintive but beautiful prints taken with the camera.
Felkl is able to create a connection between the apparatus and the image made.
From a camera collector's perspective, he finds camera I've never heard of and makes them so desirable. There is a brown leather Olympus Infinity Stylus, you heard me, brown leather and a Linhof medium format that looks like a movie camera. Amazing finds from a brilliant blogger.
