Easy to adapt sharp Tokina RMC 28 f2.8 budget wide angle lens.
Image above shows inexpensive Tokina RMC 28 f2.8 wide angle lenses repaired, serviced and adapted by Rokkorlab. This legacy manual focus wide angle is known to have good image quality but often suffers from stuck aperture. Two used lenses were ordered from auction site and both came with stuck aperture.
Repairing stuck aperture used to be a time consuming service job on the Tokina RMC. Rokkorlab studied the problem and found a way to completely restore working aperture with some thirty minutes of work enabling sharp budget wide angle lenses again.
