I don't have a severe problem with the ZX-M and in fact would recommend to anyone looking for a low cost manual focus solution. I don't care for the plastic lens mount but it seems ok and the lack of TTL compatibility. As to the ZX-L and ZX-30 never had them. My complaint is specific to models like the ZX-50 that do not support M & K mount lenses.
The ZX-M is much like the older styled manual focus models in function and appearance...other then the plastic and low weight. But it also sports several modern electronic functions including DOF. > Now guys, cool down a tad. My wife uses a ZX-30, > ZX-L, and ZX-M. She loves them. She knows I follow > this group,
