Not to be redundant but:
Canon QL 1.7 has a great lens, shutter speed preferred with manual override. The meter sensor is within the lens set so filters cover the sensor. Works well with hearing aid batteries.
Konica S3 has one of the best 38mm 1.8 six element lens that Modern Photographer had ever tested, shutter speed automated, no manual override.
Konica S2 has a very good 45 1.8 built in lens hood, parallax correction both shutter speed preferred and manual override.
Konica S 1.6 has a 45 1.6 7 element in what recall in 5 groups. Much harder to find than the S2, I am looking for one.
Minolta Hi Matic 7 was very similar to the Konica S2, at least mine is, 45mm very good 6 element lens, as good as the Konica 45 1.8.
Olympus 35RC, 42mm 2.8 tessor or style lens, lens is good by not as good the others, but very small, manual override shutter preferred. It has gotten good reviews, I have not just taken a cotton to it.
Petri 7S, 45mm 2.8 tessor lens, rather sharp stopped down. Selenium light meter, easy to use not many faults.
Petri Color 35mm scale focus compact with a 40mm 2.8 my guess is the lens is another 4 elements in 3 groups. Very small and easy to carry, mine is a good picture taker, I usually carry my Canon or Konica S2
.
Kodak C III big. I got mine as a gift in 1965, meter is still spot on the lens is 5 element F2 coated and very sharp. But control layout is odd by todays standards, would take some getting use to.
