Thanks sean, yes you're right I was using the Minolta as a benchmark, as it is similar in price and size to the pentax.
I'm in the mood for a killer normal lens. I don't know whether my 35/2 SMC Tak (which I don't have access to at the moment to play with) is going to keep me satisfied.
It does have wonderful bokeh at f2.8 and and at a close focus distance though:
Do you think its worth shelling out the dough for a high priced normal over the 35/2 SMC Tak? The zeiss I don't think will match the pentax or Sigma for bokeh...if my understanding of zeiss optics are correct.
Maybe I'll continue my hunt for a travel tele instead of an all-star normal....
