A Q might also be worth considering - there have been some great bargains for those recently - but they do not have an optical viewfinder either.
Just to add to your 'shall I shan't I,' did you know that Sigma do an 18-250mm too which is different to the Tamron/Pentax ones.

I've done quite a bit of reading on the 18-250 and the general consensus is that it's a good lens,just one question: Do the lens correction options available in the K-5 work with both versions or is this only useable on the Pentax branded lens?
IQ is quite important to me, as I like nice colours and contrast as well as decent sharpness, I'd ideally like to move forward with a lens that focuses more quietly that the 4.5 year old Sigma 18-200 DC that I've used with my GX-10, that really does have a noisy focusing mechanism and makes me conscious of shooting in some situations. How noisy is the 18-250 when it comes to focusing?

Hi Brian
I tend to use hides an nature reseves, such as those associated to Wildlife Trusts.
I have been meaning to get a two seat hide similar to http://www.ebay.co.uk/itm/2-MAN-SHOOTING-DOUBLE-HIDE-TENT-BLIND-CHAIR-FOREST-LEA...
I do wonder about the quality though. I've also read that the single seat versions are too small

The Pentax lens (ie 18-135mm)is actually very good to even excellent in the image center but the borders/corners suffer from massive field curvature at the wide end and plain sofness at tele settings. This is certainly no issue for portraits and such but you don't really want use this lens for architecture or landscape photography here. This is also in so far surprising because the (cheaper) Pentax SMC-DA 18-250mm f/3.5-6.3 (a Tamron design) was actually very usable here. The secondary characteristics (distortions, vignetting, CAs) are about class-average.
I cannot comment on the 18-135 as I haven't tried one but both my 18-250's are pretty good, even at the long end where sometimes zoom performance drops off.
Photozone actually conclude their review saying
Better consider the Pentax DA-SMC 17-70mm f/4 SDM instead which is a far better lens.
