Pretty easy thing: to stay away from depressing companies...

I never looked back after I sold all Pentax gear - the only lenses I kept in good memory were the 50-150/2.8 and the  10-20/3.5 from Sigma.

    Nor did I,  actually at the time there was a better selection of third party lenses, I had the Sigma 50-150mm F2.8 which I chose from this site, a great lens which went to Poland, some guy picked it up for a steal.....on ebay...now Tamiga release none of the glass that Pentaxians so desperately could do with.
  
  I have absolutely no idea what Pentax is up to and whether there ever will be a modestly complete FF lens selection before ML wipes the floor with DSLRs..........

                   ......which it will!
