Manufacturer description #1
In cramped quarters where you must get as much into the picture as possible, without backing up, the 28mm f/3.5 Komura is a logical first choice. Despite its great angle of view, images are sharp from corner to corner, and are bright and clear for easy focusing. A superb lens in constant use by news photographers. For 35mm rangefinder cameras with Leica/Canon type threaded lens mount.
Manufacturer description #2
When you are forced into a corner, yet must get as much into the picture as possible, then you will welcome the ultra-wide angle Komura 28mm f/3.5 lens. Even at full aperture it produces corner to corner sharp results. An excellent choice for architectural, interior and panoramic landscape photography. Available in mounts for a broad range of popular rangefinder cameras.
From the editor
Most Komura booklets indicate the accessory size of 43mm for this lens, but one of the booklets says 48mm.
