Legendary single-lens reflex camera. It was designed from the following four concepts.
1. We will pursue automation of operations with the goal of making it a compact, easy-to-use camera with excellent quick shooting.
2. We have a wide variety of interchangeable lenses and accessories to make a system camera that can be used for various shooting purposes.
3. The exposure meter, which is completely linked to both the shutter speed and the aperture, is a detachable external metering type (because the reliability remains uncertain with the built-in body type). For that purpose, place the aperture ring of the lens on the mount side and attach a claw to link it with the exposure meter.
4. The lens mount will have a large inner diameter (44 mm) so that it can be used for compatibility and long-focus lenses and large-diameter lenses, and will be a bayonet type (made of stainless steel) in which the position of the claws of the aperture ring is constant.
