I'm not very familiar with the limitations I will have to deal with using a K mount lens. Could you or someone explain them to me? Also, why is it I'm having such a hard time finding the Komine lens in a KA mount? I'm pretty sure they were made, but all the ones I have found lack the 'A' apperature mode.
