RE: Tamron introduces DI 17-50/2,8
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 Regards Jens Bladt http://www.jensbladt.dk -Oprindelig meddelelse- Fra: Sylwester Pietrzyk [mailto:[EMAIL PROTECTED] Sendt: 15. februar 2006 17:18 Til: pentax-discuss@pdml.net Emne: Re: Tamron introduces DI 17-50/2,8 Jens Bladt wrote on 15.02.06 16:57: > I don't believe that.

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...

Re: Tamron introduces DI 17-50/2,8
Consider also that the Pentax DA 16-45/4 is a recent introduction that has probably soaked up a lot of the immediate demand for a lens in that range.

I just don't belive it's profitable to make them with Pentax mount. The Tamron AF 200-500mm is not available in K-mount either. But the old MF was (very rare). I guess there's just not enough K-mount buyers. So they just make them for Canon and Nikon - which probably covers 90% of the market. Or perhaps Pentax just paid Tamron not to ;-) Pentax and Tamron has been coopereating before, since Tamron manufactured certain Pentax lenses.

I believe I have read this here before: selling lenses or sensors is a different business line and they just sell to make money. It is not the first manufacturer not to issue a lens in Pentax mount.

Maybe they sold too few of it in Pentax mount? Tamron's got a couple of their best lenses which aren't available in K mount, notably the 180mm Macro.
