I hope I got your attention Im looking for a telephoto lense in about the 300-400$ price range for a Pentax. Im really not sure what to look for and I dont really know what zoom I am looking for either. I was thinking that maybe 300mm would be good enough for most photography, but Im not really sure. I have never bought a lens besides the kit lens which so far is serving me fine. Initially I thought that maybe the Pentax SMC P-DA 18-250 MM F/3.5-6.3 ED/AL (IF) Zoom Lens, but people are saying it may be too slow. But then, what is an ideal aperture that overall good and not expensive. Thanks P.S: Can anyone tell me if these 2 lenses are the same, or if one is better than the other: Pentax SMC P-DA 18-250 MM F/3.5-6.3 ED/AL (IF) Zoom Lens Tamron Zoom Wide Angle-Telephoto AF 18-250mm f/3.5-6.3 Di-II LD Aspherical IF Macro Autofocus Any suggestions? Anyone?
