Manufacturer description

A 92 deg. angle of view provides over twice the coverage of a normal lens. The image is uniformly bright over the entire film plane with no image distortion. Since the mirror must be locked out of the light path when this lens is used, a special viewfinder is provided which clips on to the top of the camera. While the W-Rokkor 21mm may be used with the Minolta SR-T 101, the locked up mirror prevents through-the-lens exposure measurement.

From the Camera 35 magazine (December 1967/January 1968)

This is a nice light lens that can be expected to do a very good job, especially when you consider its reasonable price. To use this lens, you have to lock up the mirror; also, it does not hook up to the automatic exposure operation of the SR-T 101. The mount is made very well, and in operation it is not difficult to see why many pro and amateur photographers alike rely on their Minoltas. It is a good choice if the 18mm Rokkor is too slow for your taste at f/9.5. Definitely a good buy.

Notes

  • The lens was designed for use with 35mm film SLR cameras with the mirror locked in the up position.
