Remarks:

The DCF 8×36 HS, no longer produced, were something like Pentax’ budget roof prism binoculars with phase coating. Not fully waterproof, since their focusing mechanism is based on moving the objective block forward and backward in the tubes, they were made splash-proof by sealing the front end with an additional glass before the objective lenses, which of course costs a bit of light. That’s perhaps one reason (among others) why the image is, despite the larger 36mm objective diameter, slightly darker  than you might expect. Overall performance is decent for a low priced instrument, the field of view is a bit on the narrow side.
