With my Fujica ST705, it takes two fingers to get the meter to work with non-Fujica lenses. With one finger, I depress the shutter release half-way, and with the second, I depress the preview button on the front. Then, in almost every case, the meter responds just like the Spotmatic.

... and additionally you can fix the preview button on the front by pressing and turning it (think it was to the right side). This way you have metering with all M42-lenses by simply pressing the shutter release without further action. 🙂
