It is a great lens for macro shots, but not usable (owing to blurred focus) for subjects more than 20 feet away when a converter (such as MD to PK) is used for lenses of focal lengths greater than or equal to 50mm. Camera Pentax ‘K-5 II s’ was used for creating this album. However, a lot of people are still looking for Minolta Rokkor lenses especially f1.2’s and f1.4’s because of their quality and ruggedness. But all Minolta photo gears have been obsolete. Yet Olympus and Panasonic are still making converters for Minolta lenses. Certain old lenses produce images better than modern lenses do.
