Yes, Sigma makes a EX 170-500mm F5.6-6.3 APO for Pentax and others. It's even reasonably priced at apr. 600 Euro (Germany) = 725 USD. It's probably a very good lens: http://www.treknature.com/gallery/Africa/South_Africa/photo12819.htm http://www.treknature.com/gallery/Africa/South_Africa/photo17020.htm http://www.treknature.com/gallery/Africa/South_Africa/photo5957.htm http://www.treknature.com/gallery/Asia/India/photo10701.htm http://www.treknature.com/gallery/Africa/South_Africa/photo19822.htm

I can understand lack of 200-500 and 180 in K-mount as they are expensive lenses and Sigma makes the ones with very similar parameters, but 17-50/2,8 would be very popular among Pentax DSLR users. If Tamron did it in Minolta mount and KM DSLRs has sold in lesser quantities than Pentax ones then... But of course Pentax makes some remarkable DA lenses (DA 16-45, DA 14, DA 12-24) while KM only sold Tamron's clones of htier WA angles for DSLRs and KM never had high quality standard zoom like DA 16-45/4 for their DSLRs. -- Balance is the ultimate good...
