We have two Techniscope 2perf cameras for our production. If you have the gates widened to full perf to perf, as we did, adding a couple more 22mm to 24mm plus, you achieve more framing options. As for gate hairs one must use compressed air always between loading and blow the mag throats out as well. Its not a big problem and frankly if you get one you can remove in post often very simply.
Its a great format at stock 22mm, or modded, Its larger than S16 and can look fabulous on a good scan to DI. And is still a cost savings and longer mag time than three perf, appx 8.75-9min per 400'
The cameras still come up.
