The DA 16-85mm is very good and versatile, but it is heavier, larger, and costs more. It is also not as overall versatile as the much more compact DA 18-135mm, which is great for someone just starting in a very unfamiliar format, to discover what various FLs will be like in actual practice. It also has a deserved reputation for its AF speed and accuracy, and I've not heard complaints of bad copies.
Of course, a 15mm Limited or DA 12-24mm could come later.
If wanting to go really high-end, there's the very compact, excellent DA 20-40mm f/2.8-4 DC WR Limited, which makes a great combo with the DA* 50-135mm f/2.8 (WR SDM) tele zoom. It is very compact for what it is. Great imaging quality. In this case, the Pentax lens actually weighs considerably less than the Fuji 50-140mm f/2.8 counterpart, and costs less. Great for low light use with the KP. I have both of the above setups, and use either as needed. But this is talking a lot of money, very likely beyond the budget.
I wonder if the post has been located of the other Canadian who bought a new KP for a ridiculously low price- around
$600, I believe!
