Lovely image.
Engeneus 28-70 f/2.6 is an old lens, but it is an AF lens. The colour not reach as 180mm f/2.3 APO saturation. But this 2 lens is better than all Japanese lens, included new Nikkor Japan made Zeiss lens. For portrait taking just below the level of Zeiss T* lens , West Greman ( exclude East German Gena lens). And Lica lens.
