Ergonomics and design:
The lens is characterized by very low weight (80 g!) And compact size. Just microscopic dimensions despite the fact that the capabilities of the lens are quite serious. Build quality is excellent.
The focus ring is located at the very front of the lens. It is far enough from the body ribbed. Focusing is comfortable. A full revolution of the focus ring is about 150 degrees. The front of the object has the shape of a funnel.
The front lens is quite deeply recessed. The aperture control ring is located about half the “road” from the front edge of the lens to the lens. The ring is ribbed, its course is light and short. But because of its deep landing, it is still not very convenient to use.
Aperture blades are black, matte. The specificity of Orion-15 is such that even on the most open aperture, the petals form a distinct heptagon.
Art features and photo examples:
Orion-15 has a high resolution. And due to its FR - it also has an excellent depth of field. In color, this instance is also very good. Juicy, contrasting, vibrant colors. In practice, it shows an excellent sharp picture with a pleasant color rendition.
