Q: 7. Will this micro adjust fit on a RRS BH55 ballhead with quick release panning clamp?

A: Yes, the Slik SMH-250 Micro Adjustment Mount should fit on most Arca-Swiss clamps. But the clamp should not be a lever but a twist knob. The lever ones are so precise that there is no room for error on the third party built in Arca-Swiss plate.

Q: 8. Will this work on an older film Canon A-1 or T-90?

A: I dont think so!

Q: 9. Is this compatible with the Canon EVF?

A: If you are talking about the EVF-DC1 I do not believe it fits. I think the recess is a bit deeper and a slightly different shape. The EG diopter has a clip back and slides over the permanent eyepiece on the 5D Mark II and III SLRs. I do wish that Canon would boost the adjustable diopters to +3. I hope this helps.
