So here it is - Hi-Matic, the first.
Minolta Hi-Matic 7s - front
As you can see, it has a fixed 45mm f/1.8 lens and is in nice condition for a 1966 camera. It's not small and is (at 0.7kg) heavy with it, being built extremely robustly. The light meter is working fine, as the previous owner had said. It presents the user with the EV of the scene.

The viewfinder is nicely clear and the patch is distinct.

If you want to go with automatic exposure, you turn the shutter speed and aperture rings to select both of their 'A' positions, leaving you to just deal with focussing. Aperture priority is selected by leaving the shutter speed ring set to 'A' and dialling in your chosen f stop. The opposite is obviously the case for Shutter priority. The number showing in the little cut-out window that you can see to the right of the 'A's on the rings can then be matched to the metered EV reading. Alternatively, you can obviously go fully manual and if you dial in the rings to show the correct EV, you can turn them both together to maintain the correct value in the window. I read that the Hi-Matic was the only true rangefinder to offer all four shooting modes.
The focussing ring is the matt coloured one - it has a little tab on the underside of the lens and the throw is extremely short - perhaps 45 degrees. Film speed is selected from a slider on the bottom side of the lens. The film advance lever, though, has a huge angle of throw - all the way around and to the front of the unit.
Well, I made some images (mono recordings only for now, I'm afraid, Pete). I loaded a 12 exposure length of Foma 200 into a cannister and ventured forth. A quick prowl around the house and garden later and we were ready to develop them in Rodinal for 5 minutes.
