Pario Mechanically Controlled Shutter - Stepless?

[Dave S.]

I recently acquired a Canon A35F. Many have categorized this camera as simply a Canon Canonet 28 (new version) in black with a built in flash. One other distinct difference appears to be the shutter system employed.

Canon Canonet 28 (new):

Copal mechanical program shutter which was coupled to shutter speed-priority EE.
Metering range of EV 1 (f/2.8 at 1/30 sec.) - EV 17 (f/14.5 at 1/620 sec.)

Canon A35F:

Pario mechanically controlled.
Metering range of EV 9 (f/2.8 at 1/60 sec.) - 17 (f/20 at 1/320 sec.)

I've read online that the Canon Canonet 28 (new) is a "stepless" shutter system. My questions are,

1. What is a "Pario mechanically controlled" shutter system? (i.e. How does it work?)

2. Is it also "stepless"?

Thanks,

Dave

I haven't ever heard of a "program" leaf shutter that wasn*t stepless - that is the cheapest way to build them, and the attraction of these "program" (or rather, time/aperture coupled) shutters for manufacturers was that they were cheap, by doing away with half the regular shutter by integrating the aperture in the shutter blades itself (or vice versa).

Thanks for the info servo. That makes sense, but its still news to me. Nevertheless, it is unfortunate that canon didn't use the same shutter as in the Canonet 28 (new). I would have liked the 1/30 and 1/620.
