Dare I say another option could be a small zoom. I previously would suggest a nice little prime (DA35mm, DA 40mm, FA 43mm, FA 50mm etc) but I have been very impressed with my FA 20-35 f4.
It gives you a nice medium wide to 'normal' FOV on the APS-C body.
Its not as fast as say the fast 43mm f1.9 or 50mm f1.7, but it is sharp wide open at f4 where as I have found the FA 43 needs to be f2.8 and smaller to really get the best out of it IME and doesn't really have much of an advantage in real world low light situations.
As a walk around lens, I prefer the 20-35 over the 43, the 43 is better for specific subject photography or portraits.

Just an idea

Cheers Phil, its great for some cheap Macro fun, although this dreaded LBA is rearing its head and I am thinking about an FA50 or FA100 Macro, thats if I get a proper taste for Macro!

I think the FA20-35 might also be better due to the deeper DOF, being 60-100mm FOV rather than the 150mm FOV from the FA43.

First Macro shots using a KAX MC7 Macro TC, never done any Macro photography at all!

I think the FA20-35 is as good as the FA43 if not slightly better, although @20mm and 1:1 its basically touching the subject with the UV filter!

I have been researching all morning on various ways to get some macro action on the cheap.
Was about to push the button on a Raynox adapter but thought I would give this a go first!

Yes please Phil

Really interesting collection of photos, mostly of that 'decisive moment' shot rather than technically perfect.
Never been able to do 'street' style.

Bit of a pic dump from the weekend.

AFAIK, the 'K-3' is reference to a rumored optimistic FF model or 24mp High End APS-C model.
That's what I have picked up since getting into Pentax in the past few months.
