I shot with the K-7 hands on and tested it for more than an hour, it failed in many ways as far as image quality aspects are concerned and thus I just "fell back" to get something "better" in the Pentax land, which I think is surely the sensible choice for me.
I shall report back later on with a mini review on the K-7 as well as a simple shootout test against my K5D and you will soon know why I did not choose the K-7 (Sad but I shall honestly share my findings). Update: Here is my that K-7 hands-on test and the findings.
Surprisingly, I have also found that my Olive DAL 18-55 Kit Lens is obviously sharper than the DA 18-55 WR which I tested. So, my choice has been just so easy. One K-7 + DA 18-55 WR > 2 x (One K-m Olive + DAL 18-55) in cost but IQ/PQ wise the K-m is just better! I'm not kidding and you will soon know why!
Well, the Olive K-m has just 1,000 units on Earth and I have got one of them, too! :-D
