I made a right-angle mirror viewer for my Rollei TLR

[ame01999]

I was quite into Walker Evans during college and read that he might have used a right angle mirror for some of his street photography. (I assume his portraits of subway riders sitting across from him would have just required a 'periscope' or right angle viewer so he could glimpse down at the camera presumably hidden in a held bag or under his coat).

Well, a decade after college I got into laser cutting board games, and now another decade later I finally realized I had the technology to at least make a passable right angle mirror for my Rollei.

Some caveats: right now the only thing holding the device in place is the friction of the Bay 1 to 37mm adapter on the taking lens against the wood frame. I don't yet have an extra adapter for the top lens, but hopefully the fit will be tighter once I do. I worry about having to secure it with a free hand.

I used two standard sized 2" front-surface optical grade mirrors. I thought they were going to cost me about $160 through an American supplier, but the pair I found for $25 from China on eBay look just great to me.


My chatbot estimated just a 45mm wide mirror set at 45 degrees would be wide enough to encompass the field of view of the lens. Unfortunately, the viewing lens is capturing something 'wrong' at its right edge. I'm not sure if this was a conceptual mistake or an implementation mistake. But the view lens is f2.8 and the taking lens f3.5. If I don't shoot wide open, I'm hoping I can get a full image without any stray reflection.

So, I still need to get an extra adapter to snuggly fit it, and then I'll shoot some film and hope for the best.

Paul Strand used a mirror for some of his street photography. Like the famous 'Blind,' 1917. Paragraph 3 here...

You should put a printout of an iPhone camera side on the front of the wood!

That's neat. But I suspect the box will cause vignetting. It's ~32mm wide? A Rollei hood is 42mm wide and only 22mm in front of the lens.

What I do is just hold the camera sideways.
