"Piezoelectric film". Is that the basis of the angular motion sensors for the Kamakura Koki Techno-Stabi for Fujinon and for the almost identical ones they make for Nikon branding?
We know that there are some type of "solid-state gyro" (??) which sense rotations around at least two axes and send
signals to actuators which change the shape of the Canon liquid wedges, or to the linear motors which move the correcting optical elements in the KK . Is the PE film the key element in the vibration sensors?
The Fuji Stabiscope $$$$ and the Peleng ( Soviet/Russian) , or the Fraser-Volpe, use rapidly spinning discs, of the traditional gyroscopic type, to stabilize/move prisms at the nodal point of the system. Is there also a Chinese copy now? There was a recent post by someone in Spain who has been inside those spinning rotor types. The substantial links he/she provided were in Russian (Cyrillic text). Was there a translation available via Google or ???
Is that person in Spain a Russian speaker or reader? Working to fix the gyro types used in helicopters in the Spanish- Tunisian- Italian(?) tuna industry who pursue the remnants of Atlantic Bluefin in the Mediterranian , violating self- imposed quotas and prohibitions? Or for military applications ?
I found the original Fuji gyro stabiscope to have a yellowish caste, and the Peleng more. I have not looked through a Fraser-Volpe.
I use the 15 x 50 Canon. When acquired used, it had functioning stabilization, but was out of optical alignment . Canon wanted 600 or 700 dollars to fix it. When I pointed out that that was close to the cost of a new or functioning used one, they halved the estimate. They returned it, without service, and in horizontal storage, it (coincidentally??) self -corrected , to my surprise. It has functioned well for several years. I use top-of -the -line Energizer lithium batteries.
When space and portability permit, stability is somewhat improved with a shoulder mounted , counterweighted, inertial stabilizer which has an eight foot painter's extension pole forward of the observer.
