Originally posted by jacharles50 Hello--I have just registered for this site, specifically to learn about the Pentax K-1. I'm sure like many of you, my first (film) camera was a Pentax (ME) Because I couldn't bear to throw it or its lenses out, I still have them after 30+ years! Anyway, when the digital revolution hit, for reasons that had nothing to do with Pentax's offerings, I moved in Nikon's direction. (it was a gift.) I now have a Nikon D600 with 3 lenses that I really like: the 17-35 2.8, the 50 1.8, and the 80-200 2.8. I was thinking it was time to upgrade, and I was thinking the Nikon D810. But I have always in my heart a soft spot for Pentax, and when the K-1 was announced, I thought this sounds like a better camera than the 810, and certainly cheaper, and it would be great to get back to Pentax! But I am worried about lenses, since it is a very long time that I have looked at Pentax lenses. Could someone recommend a similar 3 lenses to the Nikon ones listed above that I should be looking for when I buy the K-1? (If I should be asking this question in the lenses section just tell me and I will do so. Thanks from a oldie (Pentax film) and a newbie (Pentax digital.)
Hi, and welcome.
Ha ha, asking for lens recommendations can be a little tricky in the sense that you can ask 10 people and you get 10 answers! That's because there are many possible approaches.
I'll try to help you. And you can also just re-post your question in the forum in general, and I'm very sure many will come in to help you.
OK, here's my take. When you ask for lens recommendations, I presume your are trying to replicate the focal length of those three Nikon lenses, right? Plus I presume that your existing old Pentax lenses don't match your needs?
Ok, with the launch of the K-1, Pentax also launched two zooms with focal lengths that match your needs, the DFA 70-200 f2.8; and DFA 15-30 f2.8. These are optimised for digital use, full frame compliant, are weather resistant, and have silent focus.
If you prefer film-era lenses, they are also available, but only second-hand. Of course, being film-era lenses, they will cover the full-frame digital sensor, and would also tend to render images in a more "film-era" manner, which you may or may not desire, that is a matter of taste. There may be some issues with purple fringing, but can usually be handled in post-processing. One that comes to mind is the FA*80-200 f2.8.
As regards your standard, fixed-focal lens, 50 1.8, there are many equivalents in Pentax. There is the FA50 f1.4, FA50 f1.8, DA*55 f1.4, FA43 f1.9 Limited; and many older film-era manual focus lenses second hand.

Oops, sorry I just saw your newer posts giving more specific information.
Regarding the FA43 Limited, if you are confirmed buying that, you certainly have my recommendation. I use it regularly - incredible glass. It is a film era lens still in production. Lovely colours and micro-contrast, superb sharpness stopped down, and possessing that magical pixie-dust "look".
I should mention that the DA*55 f1.4 is also very highly regarded. You may want to check that out as well; it is a digital-era lens and renders differently than the FA43 Ltd, so check their respective "looks" before you decide.

Regarding the FA43 f1.9 Limited and the FA*80-200 f2.8 which I mentioned, note that the K-1 has built in lens-corrections for these lenses (plus several other film era lenses as well). This should help take care of the purple fringing I mentioned, which can sometimes appear when using film era lenses on digital bodies.
