Originally posted by pinholecam Unfortunately, some over enthusiastic Canon guy chopped off the lever and lever guard for the K50/1.2.
Upon inspection, both can be easily removed (non damaging),
He should be arrested and locked up far away from any photographic equipment until that lever and guard grow back on.
I have a Bayonet Takumar 135/2.5 like that as well, the lever is shortened and the lens won't close on my K200d, nor on any other of my Pentaxes and thus i paid too much for a useless lens.
I only noticed after arriving home (bought it on a second-hand trade show) and testing it with several camera's (first thought is was a K200d incompatibility).
