Offers please 17-70
I sent the lens to Johnson' s with a description of the faults only to be returned with them saying and I quote "is working fine and meets pentax specifications"
Well, if this is how a £500 + lens is supposed to perform and meets pentax spec then it gives me no confidence to purchase further pentax da lenses.
Hope you have joy in your sale.
Shaun Wilson has exactly the same setup on one of his wedding cameras, so when I was out with Shaun on Saturday I mentioned that my 17-70 tended to 'hunt' and 'jiggle' on the focussing, particularly at the longer end. I swapped lenses with Shaun and found that his copy does not have any issues. However, I have narrowed this down a bit further and found as follows:
- When the 17-70 is mounted on the K-5 and AF is set at 'AF-C', the focussing issues are apparent
- When it is on the same camera and set at 'AF-S' there is little or no problem with focussing - I took close on 400 shots with this combination yesterday at a wedding, many in poor light, and it nailed focus on 95% of them
- I tested Shaun's 17-70 on my K-5 mk1 and there was no hunting or 'jiggle', even on the 'AF-C' setting, so it appears this issue may affect some copies and not others
- On my K-5IIs, there is no focussing issue with the same lens that has some minor issues on the mk1 - it locks on and does not hunt
The issues I have with mine are not severe enough to require manual focussing and I am comfortable the lens will not let me down under pressure, but only if I leave the focus setting on 'AF-S', which is fine for what I use it for.
I would be interested to hear what other DA 17-70 owners think, particularly those who have both K-5 mk1 and K-5 mk2.

It is boxed and the optics are all good- bit of dust but nothing you wouldnt get in any zoom after a while.
I will take some pics of it and post them.
Thanks

Pentax K50
initial tests on both the k5II and the k30 are I do not notice a juddery AF, it hasn't 100% nailed focus indoors under a lower light but I cannot think of a lenses that do.. we shall see how it goes but I was always prepared on this being a MF lens so its win win.
again Thanks

Having gotten rid of my K5 I find this a bit heavy on the KR so don't wish to keep it.
The cosmetic and optical condition are very good and the images it produces are very good indeed. It comes boxed with front and rear caps and hood.
If anyone is interested please PM me with an offer.
