The 'Grand Title Winner' photo just shows again that content and appeal is what makes a winner and not necessarily the technical aspect of the picture. The horizon is not level, which is slightly disturbing to me, but it can't be leveled as the framing is too tight and leveling would come close to cut the feet of the lion on the bottom left hand corner. I'm sure the photographer was fully aware of this and decided to risk it and leave it slightly skewed. Congratulations.

Where are the good quality lenses that would make me want to buy an NEX. Sony, stop making bodies for a while and concentrate on quality (optical) lenses!!!

nicolaiecostel: Poor performance from that lens. If Pentax wants to put this camera in a good light, they should really deliver it for testing along with some of their prized limited lenses, otherwise we form our opinion on samples like these, and that opinion isn't very positive. The Jpeg engine doesnt seem to be very good either. Just check the second image, look at the lacking sharpness on the island, and the jpeg artifacts in the foreground water. The third image is no where sharp, when looked at 100% and it has the same gritty look in the blues (compression artifacts ?), as viewed on my monitor. The fifth shows the lens's flaws in the corners, despite being shot at F8, and I could go on forever. Offcourse, I shoot professionally and my quality standards are pretty high, but there are some aspects that even an amateur would notice. I wouldn't go as far as saying some images look as though they were shot using an iPhone, but I think shooting Jpeg with a kit lens doesn't do this camera justicce.

Your opinion very much reflects what I thought looking at the pictures.
