stereo realist filter size?

[newfilm]

Does anyone know what Kodak Series Filter Adapter in mm would fit the stereo realist? I'm surprise it does not has threading like other "modern-ish" camera does.

I also did some search around it seems that there is some "stereo realist" made filter, but that are mostly "warm-filter", or colour correction filter that use with old blue bulb flash. I'm planning to use orange or red filter to increase the contras of my black and white hence thinking if the Kodak Series Filter Adapter would work?

One: The Stereo Realist series is NOT a "modern-ish" camera design. It dates from over 60 years ago, well before the "modern" idea of standard threaded filter sizes. The modern concept of standard threaded filter sizes grew slowly in the mid to late '50s and only came to be common in the early '60s. Nikon's 1959 introduction of the Nikon F and its line of Auto-Nikkors was the premier early example of true standardization with the bulk of the lens line standardizing on 52mm.

Two: The stereo craze in the post-WWII era, when the Stereo Realist reigned supreme, was based on slides for direct viewing and projection. There was little to no B&W usage. That antique B&W stereo episode was from the mid to late 19th century with a little carry over into the pre-WWI 20th century. You will find only color correction filters for the various Kodachrome types (e.g. Type A used in daylight, ...) were made specifically for the Stereo Realist.

Three: If you go the series adapter route, you will want to get two matched filters and adapters. You will also want to get the absolutely smallest size (Series IV perhaps) to avoid blocking the VF. With stationary subjects it is possible to use a single filter with a tripod mounted camera if you also get a conventional single lens cap. You can first align the camera, then mount the filter on one lens and the cap on the other, make the first exposure, recock the shutter (don't wind the film), switch the cap and filter, and make the second exposure. Cloud movement would, of course, ruin the final image.

The Stereo Realist filter size is 20mm push-on. At the time I was searching, I never could never find 20mm push-on series adapters. I eventually found Ednalite 20.5mm Series V adapters. By bending the tabs in slightly, they now fit perfectly, and, by the way, these Series V adapters do not obstruct the viewfinder.

dwig: thanks for the very informative lesson! that certainly explains the situation.

spavinaw: excellent, 0.5mm bigger is nice too I guess, I can shim it with paper tape and that'll prevent scratching on the metal lens ring too.

Many thanks guys!
