see this is what i hate when people slag off pentax, its an excellent company with loads of lenses and legacy lenses especially as scott says, its just a good system as canon, nikon, sony, olympus etc and because pentax dont have this huge badge loyalty they have to make their money a different way...through making better lenses and bodies
canon and nikon are good but they could release a really crappy lens or body and people will still buy it because of the badge whereas pentax dont have that luxury so they have to go in the hard way and i think they are doing a pretty good job.
