This page shows results and examples from 135mm lenses.
The amount of focus shift varies by lens. These examples were shot at a distance of approximately 84 inches (2.1 meters).
The lens was focused at f/2. Focus shift is absent.
Worth noting is the unappealing but mild color bokeh in the foreground and background (magenta/green fringes). This is due to uncorrected (non apochromatic) color aberration and is very common with fast lenses. It mostly disappears by f/4.
