Hi, I know this thread's a few months old, but I love my Hi-Matic 11 and thought I would share...
The 11 is my favorite full-size Hi-Matic for people pics outside. The shutter-priority metering system is dead-accurate after 40 years.
The big drawback of this camera of course is the lack of an aperture ring, which complicates bounce flash indoors a bit. What I do is, I put my flash on manual so I know the guide number. Then I lie to the Easyflash system on the camera to compensate for the bounce. For example, if my flash has a GN of 180, I'll set the GN on the camera to 90 in most situations. I've had good results with this method.
Anyway, here's a recent pic that shows off this camera's tack-sharp lens and color rendition...
