Originally posted by arnold The MX is robust even if light. It was meant for professional use. The ME super has weak stamped parts that bend if winding is too forceful. Mine needs to be wound more than once to cock the shutter if it sits a while. Besides, I love a totally manual camera, and have never stopped admiring the MX I bought (and still use) in 1977. It has never needed a service other than replacing the foam seals. Electronics is a weak point in many cameras, witness the common failure of light meters. If the MX is too small for your hands, attach a winder, or get a KX. The KX is a K1000 without strip down. Or put another way, a K1000 is a stripped down economy version KX.
The MX is probably the most perfect 35mm mechanical manual SLR camera ever devised. It shows all exposure info in the viewfinder, it has easy to see, easy to read metering, the controls (for me at least) fall easily to hand and it's both smaller and lighter than other cameras that possess the same features, or fewer. It also has the very lovely Pentax "Magic Fingers" loading system, which it shares with the other M cameras and the LX.
The ME Super has a soft spot for me because my dad's camera growing up was the same ME super I have now, but the MX is just *the business* for 35mm SLRs. If I need Autoexposure, it's the LX that I go for, and if it's full automatic I need, the Super Program is similarly hard to beat.
