I know this thread is about K5IIs users, but I feel that I should chime in, as I was so close to being a K5IIs user and selling my dual K5 cameras.
The K5IIs was a compelling upgrade, and I agonized over it since it came out.
A-G-O-N-I-Z-E-D.
Since the K5 has been so good to me, and opened up so many opportunities - creative and financial - I was anxious that Ricoh would screw up the eventual upgrade.
(
Friday I am probably going to be laid-off and my K5 work is the ONLY thing that might save me, but that is another story)
My shooting, and the output, tends to be crop-heavy as I work the scene for aesthetics. I routinely use about 70-80% of an image, and I print very large.
The K5IIs promised to give me that little extra sharpness, and it was compelling.
However, without the extra resolution in megapixels, I still wasn't getting more "real-estate" to crop.
It seemed like I would have to leave Pentax because of it, as the 645D was out of my price range.
I can't tell you how many times the Nikon D800e tempted me as something that would give me the extras I was looking for.
I was even willing to compromise and wait, if Ricoh would *just* give me a Pentax K5 with more megapixels and take another year or two to work on a FF.
However with Ricoh going to the Hoya parts bin, and color engineering, my hopes were dim.
So I waited on buying a K5IIs - although I REALLY wanted to get one - because it was so much better than my K5 in two very important areas; focusing and sharpness.
So now we have the K3, and Ricoh did the K5IIs upgrade right.
From a sentimental perspective, I would love to own a K5IIs, but as I use the K3 more and more that is fading fast.
F-A-S-T.
So from a "Pseudo-K5IIs" user, I can say that I am very pleased to have "upgraded" to a K3.
