ISM 50mm F1.0 Photo example (using Leica M-P)
impression
I found it a little hard to avoid releasing the lens because of the severe flare at f/1.0, and when you stop down the aperture, the lens becomes useless as a large aperture lens.
Also, with a maximum aperture of f/1.0, it is difficult to focus with a rangefinder, and I recommend using a camera with an EVF.
I feel that the Sonnetar 50mm/F1.1 (Sonar type) is more straightforward and easy to use at maximum aperture. is straightforward and easy to use.
