Preguntas
How much background blur and corner cat's-eye does the Meyer-Optik Görlitz Trioplan 100mm f/2.8 produce?
Wide open at f/2.8, the Meyer-Optik Görlitz Trioplan 100mm f/2.8 has a 35.7 mm entrance pupil (100 mm ÷ 2.8) and 100% bokeh roundness in the 90% corner (0.0 EV corner falloff). In an upper-body portrait at 4.01 m, the sharp depth-of-field zone spans 39 cm (3.82 m to 4.21 m) with a 20° horizontal background angle of view.
Does the Meyer-Optik Görlitz Trioplan 100mm f/2.8 show focus breathing at portrait distance?
Based on patent DE1805326U, tracing the focusing group at 4.01 m gives an effective framing focal length of 102.7 mm (+2.7% vs. the nominal 100 mm). You can toggle "Match subject size" in the simulator to see the framing shift live.
What optical design is inside the Meyer-Optik Görlitz Trioplan 100mm f/2.8?
