wide zoom? for real estate or indoor events with k10d and hopefully k5IIs

It just reports nothing below 10, blank. Not sure how to enter manually.

I try to get as close to perfect as possible out of the camera too but it's not easy with a small screen. LR gets it almost perfect but sometimes I have to add -4 distortion correction. It takes care othat he vertical and rotation by hand.

It does not do volume anamorphosis correction but I normally crop a bit.
