Owner reviews: Yashica ML Zoom 100-300 mm f/ 5.6

Build quality; no zoom creep, all metal body and mount.  Slightly lighter than the Zeiss 100-300.


F5.6 is a bit slow for 100-200 mm though it matches the ML 300 C maximum aperture.  It is quite heavy and long, though not when compared to the Zeiss 300mm f4.


This is another of the Yashica ML gems and is almost as sharp as the Zeiss 100-300mm f4.5-5.6.  Interestingly, the Yashica has more glass (13/10 vs 12/7) but is lighter, though the Zeiss uses three ULD elements and I doubt that the Yashica has any.  Despite the extra elements, chroma issues are not a problem for the ML 100-300, even when used with modern digital cameras.  They are not very common and are definitely worth acquiring.
