I also have a set of the Minolta 16 first series close up and infinity lenses I never use (because I like using the later cameras with the larger lens opening).
The Minolta 16 II is certainly a winner:
(1960) -- 22mm (f2.8-16); B, 1/30-1/500. This updated version of the Minolta 16 had several improvements. First, the shutter speed range was increased substantially. It now had a B setting for long exposures, and all speeds from 1/30 through 1/500. In addition, the f-stop range was increased at both the high and low ends. With the increased aperture, the lens was changed from a three-element to a four-element optic. Finally, a "distance" lens, actually a slight negative diopter lens, was added to the list of accessory lenses to allow infinity focus at all apertures. This meant sharper pictures of distant scenes at any aperture. Overall, these refinements make the camera more useful in more situations. William White considers the lens on this model to be one of the
top ten performers in submini history. The camera was available in six colors -- chrome, black, gold/yellow, blue, red, and green. Filters (18x18mm -- are not interchangeable with the filters for the 16I): 1A, UV, 80A, Y48(Yellow), 81B. Auxilliary lenses: #0 (for focusing at infinity with the lens at wide apertures), Closeup #1, #2. Accessories: bracket to hold electronic flash and tripod socket. Although the lens was fixed-focus at about 9 feet (6 feet closer than the 16 I), it's
depth-of-field was adequate and controllable with the aperture and auxilliary lens selection.
Actually two versions of this camera exist. The first says ‘Chiyoda Kogaku Minolta-16 (II)’ and the second ‘Minolta Minolta-16 II.’ This is due to Chiyoko becoming The Minolta Camera Company in 1962.
