In addition to the loud operation of the focusing motor, the Canon EF 50mm f / 1.8 II focusing system has the following disadvantages:

  • In autofocus mode, there is no way to rotate the ring, the so-called. Full-Time Manual mode. The connection of the ring with the focusing mechanism is straight. Some effort can damage the plastic mechanics of the focuser.
  • Very often users also encounter focusing errors with the Canon EF 50mm f / 1.8 II. After a certain amount of time of use, you may see “undershoot (front focus)” or “overshoot (back focus)” when focusing through the viewfinder. However, in contrast AF mode, when focusing happens on contrasting transitions - everything works great.

Despite the fact that the manufacturer provides for the introduction of a correction to the autofocus operation lens (by soldering the jumpers on the electronics control board lens), I came to the conclusion that even by swapping the jumpers, it will not be possible to completely get rid of the floating focus problem in the Canon EF 50mm f / 1.8 II. It doesn't matter which camera.

I find this to be critical, despite the fact that the previous version of the Canon EF 50mm f / 1.8 II had a slower focusing speed. This was the only thing that irritated me in this lens. You can close your eyes to a lot, but closing your eyes on the autofocus curve is simply impossible. In general, during use, it is necessary to keep this unpleasant feature in mind, otherwise, you can take pictures of a marriage.
