That first one would have been perfect if the focus was on her eyes. Maybe that's why you need Nikon, Pentax AF not so good/reliable?
Pentax could use more AF points for sure. I also had it setup for SEL3 mode and forgot to change it back which hurt the image. Good enough for web and 8x10 print, but yea, anything bigger and that will be noticeable to the trained eye for sure.
I use the D800 primarily because of the low noise at high ISO. I feel comfortable shooting upto 6400 and still deliver a pretty decent print size. Part of that is down scaling from the high resolution sensor as it covers that up. Then there is the AF system which is much faster because of the lenses, not to mention more AF points to select from. Just wish they would cover more of the frame.
The other part is the flash system. The triggers and lights I've bought into don't really support Pentax too much. If I want to take full advantage of my Profoto B1 for example, I need my Nikon as the HSS/TTL trigger does not work with the Pentax system.
Then there is the lenses. I finally get it after arguing against the point for years. It's not the holes in the lineup, as that doesn't bother me, I'm quite happy with the focal lengths I have. It's the designs themselves. the DA*16-50 for example isn't overly impressive, while the Nikon 24-70 blows me away every time I use it. I prefer the look of the images I create with the Pentax DA*50-135, but the AF speed of the Nikon 70-200 f2.8 VRII is mind boggling near instantaneous. Then the DA*55 is just a gem, but it's painfully slow to focus.
If Pentax makes the splash we are all hoping and there is enough push maybe these companies like Profoto, Sigma, Elinchrom, etc. will all add Pentax compatibility. but I'm not holding my breath.
I'm taking my K3, DA*16-50, DA*55, DA*50-135, DA40, and FA77 along with my Profoto B1 with me to McBride BC in a couple of weeks to shoot in the rain forest there with some models, do an editorial I plan on submitting to a few magazines. Mostly taking the Pentax kit because of the huge weight advantage. I don't even want to know how my back would feel with the B1, D800, 24-70, 70-200, 50 Art, and 135 f2.0 DC on my back for a 1.3 hour hike each way. not to mention carrying a light stand, water bottle, and snacks.
oi-vie.
So right now it's a great complimentary system.
EDIT: Reasons for still loving my Pentax:
better weather sealing
FA Limiteds are made from the ashes of Zeus and Hades
DA*50-135 is possibly the most under-rated lens
huge size and weight advantage
less intimidating with models
I feel more relaxed shooting with it
