Konica EE Matic Lens

Hexanon 42mm/2.8 Triplet lens was in Konica EE Matic produced in 1967 at 13,300 jp yen at that time. Modified lens with Minolta MD Rokkor 50mm/1.7 has the lens unit Hexanon 40mm/2,8 instead, needles to say, 6 of original Gaussian glass parts had been removed remaining iris mechanical construction. Triplet lens unit is fixed inside of barrel fulfilling the requirement of infinity position that is just behind the iris. I know that moving the construction of iris has some tendency of wine barrel shape aberration, using Leica format on APSC takes effect to eliminate the phenomena.
Critical situation test proves that Triplet has innate disadvantage on the correction of aberrations, halation, ghost, double lines Bokeh, coma aberration, etc. In case of ordinary use, have I no complaint at all.
Hexanon 42 mm lens had been used in relatively unstable and lough condition in focusing procedure because of double image focusing distance measurement, but now, Digital live view enlarging system makes it possible to focus ultimately, it's like an incredible dream!
Though Konica EE Matic camera was destroyed as a cultural property, the heart, central part is survived, Hexanon lens has been reused now!
