Riconar/Rikenon 55/2.2: Samples [1] - FF - f/2.2 + close focus (helicoid) adapter

Camera: Sony a7c (FF, 24MP)

Lens: Riconar 55/2.2 at f/2.2

The Riconar 55/2.2 lens produces a different image when focused by the close focus (helicoid) adapter (instead of the lens mechanism). More samples at f/2.2 with the Sony a7c (FF, 24MP):

The soft focus effect is greatly reduced. The lens is more like a triplet.
