I totally agree with the above author. The Pentax MZ family is notorious for this problem (except MZ-S). That plastic gear will one day break no matter how hard or how light you use it. Other than that they are wonderful bodies, small, light, thoughtfully designed, very undisturbed (vibrationless, noiseless) mirror slap, easy to manipulate the camera settings. I just hope that your MZ-10 won't easily die in your hand. Mine is now in heaven. ^^
