Vivitar ES, Minolta Hi-Matic 7sII and Revue 400 SE
The Vivitar ES, Minolta Hi-Matic 7sII and Revue 400 SE. All those cameras are very similar. The were all built by Cosina. The 1:1,7 - 40 mm lens was built by Minolta in cooperation with Leitz (Leica) The lens was called "Elcan 40" (for Ernst Leitz, Canada). Minolta and Leitz had some coorperation as you will know. The lens of the 35 ES and 7 S II is said to be similar to the summicron 1:2,00 - 40mm in the Leica CL = Leica - Minolta CL (and Minolta CLE) I mean the old and heavy Konica Auto S 2 with 1: 1,8, 45 mm lens.
