    Happy with the purchase of the Mamiya 80mm lens.5.0/5

    Happy with the purchase of the Mamiya 80mm lens. The few shots I have made with the Mamiya 80mm have been quite sharp. The small size of the lens makes for a light weight kit with the GFX100s.

    It does not work as you say.1.0/5

    It does not work as you say. Today I tried to use it to focus ring, it was loose and it came out of the lens barrel, as I was disappointed .

    waiting to develop the film5.0/5

    waiting to develop the film happy with the operation. not smooth as a leica rangefinder lens, but the long throw makes focusing easier. surprisingly short min focusing distance (0.7m) for potentially good close ups. waiting to develop the first few rolls to see the results.
