I'm missing the K-5 (II) here. It is not too expensive. Same goes for the K-50. With all respect to my fellow replyers but the newer K-70 has the pricetag that comes with it, simply because it is newer.
When I was looking into buying a camera (well actually it lasted quite a while between browsing for and actually buying the camera) I also was drawn to the K-50. Initially simply because of the weather sealing. Later also of the underdog position of Pentax, seemingly following their own path. I wasn't wrong
Lastly the picture-quality, though other camera (brands) can make lovely pictures as well, I'm sure.
What I ended up with was a secondhand K-5 II for a nice price, comparable with the price of the K-50 I was looking for the year before. Bought it together with a Sigma 18-250 lens. What I really, really liked about the K-5 II is the full, Dutch manual that came with it. Sadly it was the last model that came out with a paper manual if I'm right. For a amateur like me, buying a first dslr I have browsed so much through this thing.
Now I believe the K-5 is more an advanced model compared to the K-50 or K-70, missing the wee lcd screen on top for example. I really like that screen, but i reckon you get used to what you've got fast enough.
Anyway, what I'm pointing too is that there are a lot of nice older models that have a nice price to it. The shutter-count is supposedly something like 200.000 for a k-5, though I read more than once about going waaay over that. Anyway, I wouldn't worry to much about that. And, you can
find out the shutter-count as I'm sure you already know. Mine had 12.601 pictures made with it when I bought it. And now, about 18 months I got the camera, it is about 20.000 pictures. So made about 7500 pictures with it.
Have to say that I don't do video with it. But I think it will actually be fine for your standard stuff. You make do with what you've got right? But indeed, from what I've read the autofocus system in video's is way behind the other brands. Whatever that means.. (I know what it means
)
I also haven't got much experience with big printed pictures. Tough I do want to add that my mom actually printed a picture made with her phone (Samsung s4), two weeks ago, and had that printed in approximate 50 x 40 cm (19 x 16 inch), which I did run through Silkypix before (could have been LightRoom or name a program) just so it was in best possible quality it could get. And it came out pretty fine. I don't want to swear in church of course, but that makes me think that it should be fine all in all
Lastly, I would have expected an advice in the older camera's than K-50. The *istD and stuff. I don't own them. But I seen a lot of nice reviews, still in this time and age. And if price is an concern, because it's just supposed to be a nice gift, than maybe that is an idea?
All the best,
