Hi!
So here is the list of some lenses that I thought about recently and the
considerations that may prevent me from buying them.
1. SMCP DA* 16-50/2.8 - serious distortions at wide end, quality control
issues still there
2. SMCP DA 17-70/4 SDM - some say it is a sibling of SMCP DA 10-17 fish
eye wide end distortion-wise. Perfect otherwise.
3. SMCP DA 16-45/4 - slightly less distortions at wide end, basically
ok, though the CAs could be a problem.
4. Tamron 17-50/2.8 - suffers from curvature of field, rather good otherwise
5. Sigma 18-50/2.8 - well, I just don't quite like Sigma, and certain
people call Sigma really nasty names
6. SMCP DA 21/3.2 AL Limited - excellent lens, just not wide enough
7. Tamron 17-35/2.8-4 - covers full frame, but also suffers from
curvature of field
8. Sigma 17-70/2.8-4.5 - well, another Sigma
9. SMCP FA 20-35/4 - said to be excellent, but expensive and starting to
become quite rare these days.
No matter how strange this sounds, but it seems that there is no
decidedly good lens in 16(17,18)-45(50, 70) range for modern Pentax
DSLR. Each lens has some serious drawbacks.
So here you have it - a short summary. Please don't kill the scribe.

P.S. I already have 21 ltd, it is listed here just for sake of completeness.
P.P.S. I should watch for reviews of DA 17-70/4 and some sample shots as
well.
P.P.P.S. The price on (even brand new) DA 16-45/4 has gone down
considerably now...
4P.1S. I have placed an order for Tamron 17-50/2.8 and I may still buy
one for lack of better alternative due to its speed and sharpness.
Having excellent sample of Tamron 28-75/2.8 has its impact on my
reasoning...
