a photographer in canada responded by email to me. he said the 6008af can be overridden, however are you basically fighting the motor of the autofocus (as it's in the lens) and harming the lens? or when you switch it to manual focus does this switch the motor off, leaving you free to twist. I say this becuase the camera might make a better street shooter than the mamiya. however if i can focus well with the mamiya and weight is not an issue, then i prefer this. it's not possible for me to rent a mamiya RZ without buying the camera on credit as insurance, if i should run off with it. is the dial focus generally smooth? i would photo everything with it, as i don't mind the weight, and it is lighter than the RB. the rollei is of course great for candid shots, however as the parent company has folded, it will be EXTREMELY difficult to get this serviced. this is putting me off now. the pentax 67II is not an option for me, as the uk light does not make it an all round shooter and the loud shutter just slams the lid on that. i know with a leaf shutter, i will get less shutter shake. the Pentax lenses are faster, however the big shutter just cripples it for candids. I lack the skill imo, to get good results out of it handheld.
