    Default 50/1.8D Focus Calibration

    Has anyone ever sent their 50mm for calibration?

    My 50mm suffers from front focusing. Damn jia lat, alot of photos all the rear in focus, and i swear my af point was correct! very frustrating, alot of wasted shots.

    I have tried adjusting that lens before, not successful.
    The 50mm F1.8D does not have provision for front/back focus adjustment
    Most likely, adjustment will be done on your camera.

    Well, I could be wrong. best is to check with NSC

    i don't fancy the 35/1.8 much. but i've been poisoned by the 85/1.8 or 85/1.4.

    Was told by one NSC man that AFD lens cannot do calibration. The only option he recommeded me was to use AF fine tune on camera body.

    If really back-focus, you can try to compensate by focusing on a closer subject and use the focus lock
