Click on the images and download the full original images, which were produced directly out of the K-50 without any modification.
As before, I don't like the colour response by the way. All Prime M bodies, including the K-01, K-30 and now the K-50/500 do have a strong magenta cast like that, making images look unnatural and skin tones look especially awful, which is just awkward enough after all! >:-(
Besides, all the images were underexposed somehow and they look a bit dark, which is not normal for those kinds of subjects that are already with a mid-tone reflectance, IMHO.
N.B. The official sample images of the K-50 are NOT yet available at Pentax.jp.
