Are these the lenses you are talking about:

1. Wide Angle Lens FA31mm F1.8AL Limited Lens
2. Pentax SMC Limited FA 43mm f/1.9 in Silver Lens
3. PENTAX Camera lens FA 77mm F1.8 Limited K Mount 27980 Black

There are a lot of different types available, like the Smc, smcp, FA. Also these are all auto focus lenses and if I am not wrong the Pentax ME Super is a manual camera. If I am right (there is a big question mark there) then don't you think spending on AF lenses would be a waste?
