Sample photos of MC Volna-9

On a camera with a matrix APS-C (kf = 1.6) the camera will have a field of view equal to the equivalent 80mm focal length, and the aperture will correspond to the value f / 4,5... Why is that? Because, firstly, because of the narrow viewing angle, you will have to move further. Secondly, the camera's sensor receives 1,6 times less light than a full-frame 35mm sensor. Thirdly, although this does not apply to the previous two statements, the lens on the crop has a drop in sharpness due to the denser arrangement of pixels on the matrix and their concentration in the center of the lens.

On a full frame, the lens works as intended - it has a more flexible picture and characteristics corresponding to the declared ones. In addition, when you clamp the aperture down to f / 11, we get a really sharp image, and not a crumbling image, as is the case with a crop.

The easiest way to shoot is in the mode Aperture Priority (Av)when the camera adjusts the required shutter speed based on the current aperture value and the light in the frame. To work on digital cameras, you need an adapter from the M42x1 threaded connection to your camera. Wave 9 it is easiest to put on Canon EOS with EF (-s) mount, due to the insignificant difference in focal lengths. Adapters without focus confirmation chips are cheap.

Summary

The lens is very good and practical as a staff member. Above stated why. Sufficiently high-quality glass, and costs moderate money (based on the market).
