Pentax Optio 50 review
Surprisingly flimsy construction for a Pentax camera. Certainly not of the same quality as other Pentax digicams I've owned in the past. Camera is identical to a Vivitar model, except the Pentax has a Pentax lens. Check Wal*Mart who sells both cameras. I suspect that this Pentax is a Vivitar with a Pentax lens installed.
Very noisy zoom lens (possibly just the unit I bought and returned). Cheap plastic case.
