I'm also a new member of the K club (having mostly Ms and Takumars).
I got a K 50/1.4 from a member here at a very nice price (it had no caps and a little dust speck on the rear element) so I thought I would go for it.
I have a bunch of 50mm lenses but nothing faster than f/1.8 and I had heard the K 50/1.4 was a good one.
Well the lens is really nice - great bokeh, sharp and nice colors. Nice build too.
I found its a bit soft at 1.4 but pretty good after that.
I also find the focus area tends to be pretty 'thin' - you have to be right on it.
Anyway, here a shot I just took with it - SOOC low-res jpeg, no post.
I also shot this in RAW and will edit later but I think this lens is a goodie!
NB: Camera used is Sony A7III, natural light.
