Originally posted by Impartial I will go against the current to suggest that you start with the 18-55 version II. No, the optical imprvement probably makes no difference at 6MP, but you will then not have to worry about whether the lens (or your copy) is in fact giving you any trouble at 6MP, and will futureproof you against your next 10, 12, or 14 MP body.
Fair point, although if you're talking about buying a $25 lens, you probably don't have to be too concerned about future proofing
Originally posted by Impartial I will also suggest (with the current in fact) that you try manual focus primes to test those waters (though I personally recommend auto aperture to limit the learning curve).
Such lenses as A 50/1.7, A 28/2.8, and A 100/3.5 macro can all be had for less than $100 US and allow interesting (and diverse) shooting experiences.
I've had all three of those lenses at one point or another and you really can't go wrong with the A50/1.7. You should be able to find an excellent copy for less than $100, maybe even closer to $75 if you look around. It would complement an 18-55 kit lens well in terms of giving you some speed on the longer end.
Originally posted by Impartial Finally, I will say with or without the current that for me, normal AF primes such F35/2 or Stigma 28/1.8 are of more interest on Pentax digital bodies than an AF "fast 50", but your mileage will inevitably vary.
I would, without hesitation, recommend the FA35. Despite selling for around $375 used (which I realize is way outside of your stated budget), it's still a decent value given the IQ (IMO). I sold mine when I "upgraded" to the FA31, but to be honest, the FA35 is nearly as good in most respects. It's the kind of lens you can just leave on the camera most of the time.
