K30 with sigma 18-35

Hello folks !

Reading many reviews and forum posts on other sites I came across a comon problem for sigma 18-35 . back focus and front focus issues. Im wondering is it a same problem on k30 ? If anyone knows from his own experience ? I have k30 and just bought sigma . I wait till it arrives so Im kinda nervous. :/

The 18-35mm isn't out for Pentax yet AFAIK. Front/back focus depends on both the body and the lens, and most of the time in-camera corrections suffice (or, in this case, the Sigma USB dock). If not, you can always get Sigma to adjust the AF for you though.

It is out for quite a while and I order it . Maybe someone that has it knows some direct data ?

USB dock for pentax mount isnt out yet so thats a bit of a problem , and since Im ordering it online Im worried about having to return it for correction. :/

All ideas are welcome

Well, let us know when you get it- I don't know of anyone else that has one (it certainly isn't listed as in stock at any online store at the moment).

I have a dilivery guaratee for begining of june . I bought it from web shop in my country. The lens is avalible but its very rare that pentax users buy it so they never have it in stock. Insted its always by order only. Hope I wont be the first pentax user owning it lol.

In critical situations, you have the option of CDAF from live view,
which will sidestep virtually all back/front focus issues.

I use it regularly with the DA 20-40 on my K-50.
