Pentax (or Compatible) Lense

[PhotoDavid78]

I have the Pentax K10D and I was wondering if anybody knew of a lense that was all in one like lets say a 18-300mm??

Sure.

Tamron (http://www.tamron.com/lenses/prod/18250_diII.asp) makes an 18-250 lens, which is believed to be identical to Pentax's (http://www.pentaxslr.com/lenses/lens_18_250) offering.

Sigma (http://www.sigmaphoto.com/lenses/lenses_all_details.asp?id=3302&navigator=6) also makes an 18-200.

If you really need the extra reach, Tamron also makes a 28-300 lens. (http://www.tamron.com/lenses/prod/28300_di.asp)
