I only recently stepped into Pentax-land with a Kx and I caught it. The kit lens is just fine, but the same day the camera showed up I bought a DA 55-300mm. Great quality pics (if a bit slow and noisy).
So then I dipped my toe into the manual lens pool with a A-50mm 1.7. Very happy with that one!!
Not sure why, but I then bought a Vivitar 35mm f2.8 and a Kiron 80-200 f4.5 macro in a package, then a good deal popped up here for an FA-50 1.4. Then a Tamron 28-75 f2.8. Today a DA 40 Ltd. None of these 5 are even here yet!
Sick, I tell you. Too much overlap and I'll need to sell some. And yet I still keep looking at the FA/DA 35mm and 70mm ltd lens pics.
I guess I'll have to seek treatment since my camera funds are gone!
