Spotlight: Miranda Sensorex

The Miranda Sensorex is a 35mm SLR camera from 1966. I always loved the look of this model, but never managed to find a working example until my visit to the Photorama camera show last month, where I scrounged up this functional Sensorex and 50mm lens from the bottom of a box of old accessories and darkroom easels. So after coming across countless broken Sensorexes at garage sales and antique markets, I finally get to try one out!

I'd classify the Sensorex as an advanced amateur or enthusiast level camera. It has some nice features for its time, but lacks the versatility and reliability that a professional requires. It has through-the-lens metering, which is great, but the setup is pretty clunky. After attaching a lens, you must also couple the lens to a little arm, which can be a bit cumbersome. It feels a bit like the old aperture indexing system of pre-AI Nikon bodies like the Nikkormat, but much less graceful. In addition to attaching the indexing arm, you also need to set your lens' maximum aperture using a little dial on the front of the camera. After these two steps, the camera is ready to meter! It's certainly clunky, but it works. All my exposures came out pretty accurate. Be warned, the Sensorex only accepts those hard to find 625 mercury batteries, and the meter doesn't turn off automatically, so it's extremely easy to waste expensive battery power.

For me, the most striking aspect of the Miranda Sensorex is its viewfinder. Most companies just slap their name on the front of a camera's finder and call it a day, but the crosshair/star design on the Sensorex is 100% class. Unlike on most amateur cameras, the viewfinder on the Sensorex is removable. There are waist-level finders available out there for the Sensorex, but they're pretty difficult to find these days. Of course you can just remove the prism and not use a waist-level finder, but critical focus is hard to achieve in that manner. Unlike the finder, the focusing screen is not interchangeable. You're stuck with a serviceable matte/microprism screen. It works, but the screen is a bit dim by modern standards and not easy to focus with in low light.

Shutter speeds (1 ~ 1/1000 + B) are selectable via a knob on top of the film advance lever. The release is not located on the top of the camera, but rather on the front. I think this setup makes vertical exposures slightly easier to perform, but for horizontal shots the front-facing release just feels awkward.

The 50mm f/1.8 lens that came with my Sensorex performed well in my experience with it. I'm guessing mine had been stored in a damp basement someplace, because there was a bit of fungus in the glass, but this did not seem to affect the sharpness much, if at all. Since Miranda was a smaller company, there isn't a huge variety of lenses available for the system. One cool thing about the Sensorex is that it has two mounts in one: The outer part of the mounting ring is a bayonet mount for newer lenses, while the inner part of the mounting ring accepts old 44mm screw mount Miranda lenses. Pretty unique!

Overall I like the Sensorex. It's easy enough to operate and looks cool. I took my Sensorex with me to some estate sales, and on a trip to Galesburg, Illinois. I used T-Max 400 film. Below are my results.
