Accessories for your Nimslo!
Many lenses and levels were sold over the years, but my stock has run out, film cameras no longer make sense, and to top it off: I'm retired and out of business. Our own Nimslos are "retired" in favor of digital camera work these days. See below for making your own.

My accessory lenses were hand cut (for Nimslo or TECO Nimslo) cameras and dropped into the 23mm wide channel that frames its quad lens assembly. The attachment method was either black plastic tape or small corner dabs of removable (Duco Cementtm / colloid) glue. While they all had anti-reflection chamfered and blackened edges, the Scenics were uncoated (users were urged to simply use normal lens shading in sunlight). The close-up and macro lenses were made from old +1 and +3 diopter camera accessory lenses, so their anti-reflection coatings were sometimes a bit frapped out.

Viewfinder Level: This item often worked on other cameras as well. It was a nice little .218" x .938" glass spirit level with about 1/8"/foot (that's normal normal) sensitivity. The bubble centered in the lower projected frame gap. It was glued on externally (instructions).

The "Un-Close-Up" "Scenic" lens pair: In answer to that oft heard: "Nice view, --for a Nimslo", I sold a pair of "scenic" accessory lenses. Although Nimslo lenses are sharp, they were adjusted to a relatively close distance of 3 meters (10 feet): nice for party snaps. With fast film and sunny skies, distant views were actually in "reasonable" focus -and you might not have even noticed an improvement with the "Scenic" lenses installed. However, that fixed focus falls far "short" of perfection on a dull day at the "100" speed setting. But with a pair of minus 1/4 diopter "Scenics" installed, the prime focus was shifted to a very conservative 41 foot "hyperfocal" distance.

The Close-up "angle" lens: Wouldn't it be convenient to shoot close-ups with your Nimslo in the 2 to 4 foot range? Use those two inner frames by rigging them for close-up or macro use.

My "+1d" lens achieved a prime focus of 29 inches and a stereo camera window that approximates that distance. The Macro angle lens of "+3d" strength (12 inch focus) yielded a 1:16 base/distance ratio and fair depth of field in sunlight.

I suggested that if the Scenic pair is in use, that the center lens pair should be uncovered for general shooting --thus exposing 10 foot prime focus alternate frames for printing or mounting. When using the close-up and macro lenses, the the outer pair should be blocked --especially if the film was to be processed and printed by a commercial photo finisher.

The price for Scenic lens pairs was $15. Each "angle" lens was a single lens which covered any two lenses on a Nimslo, Image Tech, or similar camera).  The viewfinder levels were $3 (and you had to glue them in place). $1 bought a set of 1 stop ND filters, for more color saturation with ASA/ISO 400 negative, or for shooting 200 speed TPY or negative films (shipping included).

But now-a-days: make your own!

* Simply cut down a standard "+1" (one diopter) or "+3" (three diopter) close-up accessory lens to fit. Start with a lens which is wide enough to cover two of the lenses on your stereo camera. (Or heck: don't cut the lens at all.) You can also start with "+1", "+2" (about 17" prime focus with Nimslo), or even "+3, +2, +1" cheap reading glasses from a department store.

* For the "Scenic Pair" of lenses you need something special: a pair of glasses made to a simple prescription for minus 1/4 diopter spherical strength (-1/4d). If the lenses are large, you might be able to get a matched pair out of each one.

* Always "black" the lens edges to reduce internal reflections. I used flat black model airplane paint.
