Nope first review of a lens that I have absolutely no interest in, got a link Algi? It's way to big and fat to make it to my bag

Don't know really, Andy?
I read somewhere that Pentax use F2 sensors but just rate them as better than 2.8, no idea where though! What strikes me about the review is not really how good the Sigma is, as it's fantastic in all areas except the focus thing, it is a very very bright zoom lens, so it may be affecting the K3 Af? It's how well the 20-40 Ltd did against it and just how bad the DA* 16-50 is? The 16-50mm performance actually came as no suprise to me as I have had two of those previously and decided to bail on that un permanently but the 20-40 has now piqued my interest...

For those interested...

Fab review Danny and it was not too long, it was just right, and very informative indeed!

Added the above to my list of ones to look at, I had the original ACS that I think I sold to a forum member and I loved it.
That Tamrac looks pretty damn good guys, thanks for the info!

Thanks Andy, I had forgotten about Tarmac, remember them being in bother and thought they had folded. Obviously not!

Hey Bob that Pelican looks awsome is it a bit rigid?
How's the weight, don't mind a heavy pack if it's a comfortable pack...

Hmm they've updated that little lot since I last looked, just a bit!
No stowage though, te bag is as much about the parafinalia I carry with me as much as the camera kit...

I have the Lowepro Sport 200AW which I love but I am now carrying three lenses as well as the K3 when out hiking and one lens has to ride shotgun in the main compartment which all the butties etc, I actually caught myself idly looking up a forty limited so everything would fit in the bag! (Pentax K3/12-24/17-70/60-250) There be madness in those preciouses! I'd far rather just carry the three I have as they are my preferred choices, so bags, what backpacks do you guys recommend? What have you bought tried and still love? I'll be hiking with it multiple miles with tripod butties and water and need room for all of this and a storm shell! Make does not bother me I've looked all over like the look of the Fstop Guru, the Click Elite Obscura 2014 version but am I missing something?
Cheers in advance for your thoughts...

£600, I just feel it's the replacement to the slightly troublesome 17-70 F4, wider longer but variable aperture, the big two both do them, not really that expensive as it will drop to the same level as the Nikon 16-85mm soonish. Theirs is currently elling for a whopping £573.79 at the Nikon UK store and about £150 less at SRS, so I think we will see it drop to around £450 sharpish which is not bad for such a swiss army knife of a lens? Optics we will have to wait and see on but I personally don't see it replacing my 17-70 anytime soon, (To Mike P, my 17-70 is turning out to be the best £250 I ever spent in photography, I can't thank you enough!) which I have a story to relate about when I stop shooting the autumn stuff in the lakes and have time to do it justice...
Might be just the ticket, if the optics hold up? If it's half as good as the Nikon one it'll be a brilliant lens...
72mm thread is a bit awkward though...
