Best from this last season (summer 2017)

Serviced Tokina RMC 28 f2.8 on Canon 5D full frame digital camera.

Tokina RMC lenses are known to be fine budget manual focus lenses on the used market. However, the lens model is plagued by stuck aperture which has disabled many lenses from being adapted and used together with modern digital cameras.

Rokkorlab studied the problem and devised a service strategy where the lens does not need to be taken apart fully. The service job for stuck aperture now takes thirty minutes and in most cases fully repairs lens mechanism making the inexpensive but sharp wide angle useful again.

Image above was taken last summer (2017) with a repaired Tokina RMC 28 f2.8 adapted to Canon 5D full frame digital camera. Image quality does not quite reach sophistication of Minolta MC W.Rokkor-SI 28 f2.5 wide angle. For a 28 mm wide angle originally intended to be a budget lens sharpness is admirable and better than just good enough for most purposes.

To boost color saturation to "cinematic" level color correction filter CC10M was used in front of the lens.
