Not to confound things too much, but another 50 that I really like is the FA50 Macro....It's heavy, pretty ugly and not as fast as the other lenses suggested here, but it is very sharp and gives you a macro option. I'm also a fan of the FA 50 1.7.
I have several (M, A, F and FA) 50mm lenses.

The Pentax FA 50mm 1.7 is my favorite of them all.
There are a lot of treads that talk about the FA 50mm 1.4 Vs. FA 50mm 1.7 and comes down to preference.

You can't go wrong with either DA 50mm, F or FA 50mm 1.7 or even the FA 50mm 1.4.

It seems like every 2 weeks I'm purchasing a different version of the 50mm because there are so many options. Don't be happy with just one, try different versions. I'm up to 5 myself !

We really don't know if the DA 50 is remotely compatible with a digital Pentax SLR because it hasn't come out yet. It does OK (passable) on film. It doesn't look terrible adapted to a Sony FF, but certainly isn't great like some of the older brethren. We don't even know if Pentax will allow the DA to be shot FF on the upcoming FF - crop mode very well could be triggered automatically.

Beyond that, I would strongly disagree with the idea that these lenses are a great choice no matter what. The DA 50 is sharp in the center when stopped down, but pretty much all the lenses from the old m-series onwards are stronger in the corners and render tonality better. If portrait is an emphasis, the 55 lenses are simply a better choice. I don't own the 55 macro WR but it seems to be a superior lens overall, based on the images I've seen - although the slow AF is a valid concern. All properly built macros will tend to have slow AF because of the long throw. On the other hand, they are great for manual focus work.

I've used it on the A7, Jim, and there's no problem.

I've seen A7 shots from the DA 50, and they certainly don't measure up in the corners to a good shot from any of the manual f/1.7s or faster. It is all a matter of how "problem" is defined.

I would not mess around and go straight for the DA* 55mm.

If you can afford it, get the DA* 55. It seems to be the best of the current AF normals, with excellent contrast, color rendition, resolution and rendering. The DA 50 would make a fine budget choice.

If you can handle manual focus, the old K or A 50/1.2's would be a quirky choice. My copy of the K 50/1.2 is soft and dreamy wide open, but it's sharp by f2 and tack sharp at f2.8. This lens can be challenging to focus and once in a while it will succumb to bokeh fringing, but it renders like few normals and works really well as a portrait lens on APS-C cameras. The K 55/1.8 may be the best budget choice among the Pentax manual focus normals.

But, then.... if sharpness and color rendition are your primary concerns, don't discount the FA-50mm f:2.8 macro. "Possibly the sharpest lens Pentax ever made."

Well, this is the lens that sits most often on my A7.

if you really want a good investment, choose the da* 55mm 1.4, it's a superb lens which will last decades !
It's tough to make that statement for an SDM-only lens.
