Originally posted by NewPTXuser Photo magazines have big ads from these companies offering their wonderful new lenses, but sadly not for Pentax mount...
You have zoom capability from 12mm to 450mm (10mm if you include fisheye), and a fair selection of primes ranging from 14mm up to 560mm, a large number of the zooms and many of the primes are weather-sealed, and
everything you can put on a Pentax body is image-stabilised. That's just with current production lenses.
On top of that, there is the used market. Every lens Pentax/Asahi Optical Corp. has ever made can be mounted on your new camera and used, with at most a simple thread-mount adapter for the pre-1975 stuff (try doing that with Canon), and AF confirmation works without any fancy chip in the adapter (I know; I do it regularly). And all of
that is image-stabilised as well, right back to the very first Takumars.
Remember that a lot of these new third-party lenses are on the big and heavy side, and not necessarily weather sealed; how many can you carry around with you all day, for how long, and in what conditions?
You have better gear than some of the great names in photography ever enjoyed. Pick what best suits your needs (we can help you there if we know what sort of photography you do), get out there, and
use it.
It would be interesting to know what you think you're missing. The decision to switch is ultimately one for which the photographer themselves is fully responsible, and they need to consider very carefully what they are looking for in the new system, whether the new system fully provides that, and what they might be losing if they go over.
Consider and then buy what you
need; don't pine piteously for what you only
want.
