Prime lenses

[ing. David Lacina]

Hi,
can anyone recommend a line of prime lenses? Is the new Pentax 14 f/2.8 
worth the money, maybe some MTF available somewhere (which I missed)? I 
am doing mostly travel photography and was thinking about Pentax SMC-FA 
20 f/2,8 + Pentax SMC-FA 43 f/1.9 Limited as beginning. Any opinions?

Thanks,
David.
