Thank you everybody for your replies. I'm currently torn between either the Tamron 28-75mm or the Pentax 24-90mm. Having looked online there are both good and bad reviews of both so I'm torn which one to get. Is anybody able to say if they have either of these lenses or have owned both of them to give me an update as to which would be the better.

I did see someone had said the Pentax 24-90mm has Stella optics but then marked it down for being a bit wobbly with the zoom barrel which can effect focus and also some copies are reported to be soft as well but these were on older bodies and not the K1.

I know there are good and bad copies of everything so don't really go on them too much. I have the Sigma 70-200mm and Tokina 20-35mm so don't need the full zoom range of the Pentax and my walkabout lens is a FA35mm so would the Tamron be better?
What's more important, the extra range of the 24-90 zoom or the faster f2.8 of the Tamron, everything else being equal? Whether everything else is equal or not is another matter! I have the 24-90 and find it OK but it does have zoom creep. If you can run to it, the new(ish) Pentax DFA 28-105 is better built and performs as well as (if not better than) the DFA 24-70
That said, the 24-90 is a good lightweight lens so if weight is an issue its a good compromise. But being a lightweight lens could also be considered to be its achilles heel, it just isn't as robust.

We all know, because we're told so, that Pentax cameras can't focus on anything, apparently. Therefore all those images just have to be fake mock ups.

If you haven't used it for a while, you may have forgotten some custom settings. If all else fails try a factory reset and start your favourite settings over again.

The lightest Pentax DSLR is the KS-1 - a great little camera that uses all the K mount lenses. The KS-2 is a little newer but slightly heavier. If money is no object then look at the KP.

Note that the full DSLR K-S1 is very slightly lighter than the liveview only K-01.

Once you've bought the lenses you want for your camera, if you're happy with them does it really matter if new versions come out or not. The lenses you have shouldn't suddenly stop working (certain SDMs excepted!)
Stu, have you bought all the current ones yet? 15-30, 24-70, 28-105, 70-200, 150-450, 560 for FF and the counltess APS-C ones? If not what are you waiting for? Practically every focal length is available in zooms and primes so a new lens needs to be pretty special, not an every week event.

I see. Yes that one doesn't have the power zoom contacts to work HSM/SDM like the Kenko DG Pz-AF 1.5X TELEPLUS MC or its equivalent Tamron version. Was forgetting that. At least the Pentax one signals the conversion factor but may vignette with certain lenses. Oh well!

I've got the 1.4x WR Pentax teleconverter so surplus to requirements now :wink
But the Pentax 1.4 WR isn't strictly full frame. Have you tried it on FF yet?

The teleconverter should be good for full frame, might be worth hanging on to.
