I posted a comment last December, not too happy about the lack of a review on the K3. I don't consider myself to be a Pentaxian, but I do have a K3 and a K5, and I had a K7 and a K200d. So, you might say I like Pentax. But I also have two Sony NEX-7's, and a Panasonic G5. I had just recently bought the K3 and would have liked to have read a review by dpreview first. But, because of my past experiences with Pentax products, I had no doubts about the K3 before I bought it, Pentax products have never let me down - I won the G5 with a picture I took with theK5 and submitted to Amateur Photographer last year.
"Better late than never" may apply here, I am pleased that dpreview is finally doing a review of the K3, as the camera merits a review by a site with high reputation such as dpreview. And by this I mean that the reviews are unbiased. Dpreview may have an agenda on who gets reviewed first, but once the review is made, it's an honest review, they call it like it is.
The deal-maker for me, with the Sony NEX series, was the 24meg sensor of the NEX-7. If I wanted a smaller sensor - in megapixels - I would go perhaps Olympus OM D-5, or just stay with my Pentax K5. I don't see any 'have to have" improvements in the NEX-6 that interests me. When everything is said and done, it all comes down to the glass, and not matter which Sony NEX series body, they are still lacking a variety of superior lenses.
CAcreeks: Good to see news items about alternatives to Adobe software. Does PaintShop Pro X4 run on Linux? I guess not. Corel AfterShot Pro does run on Linux (formerly Bibble Pro). It might be a good alternative to Lightroom.
I use AfterShot Pro on linux, and it's great, I shoot RAW and do most of my post processing In After Shot, with any finishing touches in GIMP. Quick, efficient, and very cost effective.
