SMC K 30mm/2.8 vs. FA 35/2.0 lens

[akozak]

Hi All,
I own SMC K 30mm/2.8 lens and use it for slides. But consider dslr so 45m
angle would be very nice indeed. But...what about FA35/2.0 as standard
lens?What about optical performance between two?Which one is sharper and
has better bokeh?What about color rendition?Has anyone had both and could
tell which is better?IS 30mm better than FA 28mm and SMC K28/3.5?
Thank you very much for help.
Greetings
Alek
