Optical Viewfinder: Anyone use one with their A7/A7r?

[eleskin]

Although the EVF is excellent, being a rangefinder guy, sometimes I miss the type of view I get in an optical viewfinder (brightness outdoors, not being distracted by a screen image typical of DSLR's and EVF's as compared to looking through the viewfinder of cameras like LeicaM, Fuji X-Pro). For some situations, especially street photography, I can see using a clip on optical viewfinder for 35mm focal length in combination with the Zeiss 35 2.8 set to AF. Anyone else use an optical viewfinder on their A7/A7r?

I have been using my old Leica 35 Optical Viewfinder on my RX-1 and I have to say it's been ok about 75% of the time. There are times I wish I had the EVF, but I am still paying off the RX-1.
