They are (allegedly) fitting upgraded motors to the 16-50/50-135mm so once fixed it "should" give no further problems.

Welcome to the forum!
I have a K-5 with the 17-70 too. It is my main lens.
I bought the 18-125 as a travel lens but I still keep coming back to my 17-70. I also have a 60-250* and a Bigma, both of which get used for landscapes too.
I would wait a while before buying anything else, until you know what you want to photograph and what you miss with the 17-70.
Be really sure you know what you want to do with an UWA - landscapes don't work with them imho, unless you have really good foreground interest. You do not get the sweeping landscape you imagine you will - the picture format doesn't allow for that and it just ends up squashed. you are better off stitching two or more photos for a wider view. I know others will disagree with me on this, but that is my experience and opinion.
Good luck & welcome !

Hi Gwyn,
Thanks for your wise comment. As someone with experience AND very similar kit, it makes sense for me not to rush and buy on impulse.
BTW Chris, which Sigma do you own as a matter of interest?
Cheers,
Jacey.
Take care.

£600 will by you the Tamron 70-200 which I think is regarded better than the new Sigma 70-200. The older Sigma 70-200 which you'll pick up for £400 or so secondhand is considered better again.
There are also the Pentax 60-250 and the Sigma 100-300, whilst they both have a max aperture of f4 that shouldn't be an issue with your new K5. Secondhandthough these will cost a bit more than your £650.
Personally with your range of interests I'd go for the either the new Sigma or the Pentax 60-250 (wonderful lens though best used through 220/230 and cropped rather than to 250 where it softens up).

Sigma 18-125mm / 3.5-5.6 AF DC lens.
Price
£125 + Shipping & PayPal Fees.
Item Location
With my daughter in the UK (shipping to UK address only).
Item Description
Excellent zoom range for a walkabout/holiday lens and for general use. Very nice, clean, lens in As New condition (boxed). Glass has no scratches, no fungus on the glass, no oil on the blades. Lens is about two years old.
Lens will be shipped in original box with front & rear caps and hood.
18mm is wide enough for just about anything, while 125mm is long enough for most uses, a light compact lens it has the perfect zoom range for travel / walkaround. No changing lenses here if that is what you need. @18mm images are good, sharpness is fine, nice contrast, but from 35-125mm images are even sharper, images turn out great, good detail contrast and nice colours.
There is a Flikr group for it here : http://www.flickr.com/groups/18-125mm_f35-56_dc/
A couple of forum members here have bought lenses from me in the past and have given positive feedback.
Shipping : next day by PO 1 day delivery (usually), signed and insured.
Thanks for looking. Full size photos on my Smugmug account under Other / Test Shots.

Only C&C is to shoot a little wider so that you don't accidentally crop off parts of the heads or other limbs etc.

I have the 55-300 (it is an excellent lens for the money) but the problem is it is really too slow for birding, and this will be exacerbated because you are using a K10D and so using higher ISOs to keep the shutter speed up isn't really an option, nor is opening the aperture since at 250-300mm the 55-300 is already at a minimum of f5.8. You also can't add a TC since you are now looking at around f11 and the 55-300 doesn't play nice with TCs.
I've seen other posters on forums with both the older Sigma 170-500 and Tokina 80-400 lenses however they are not considered real birding lenses and the output is no better than the 55-300 in real terms though with the added advantage of extra length.
I also have the Tamron BB500 and it can get decent shots despite it's f8 limitation so IMHO if I were you I'd bank that £450 and save hard until you can afford a used 150-500 that Mike highlighted !
