Is this a good lens? Why is it so cheap?

From what I hear the 150mm f/2.8 optic is good, but not as good as the 165mm f/2.8. The 165 is a very good lens, sharp wide open. I place the 165 above the 105, 200, and 300 lenses. At least that is my experience. A terrific portrait lens.

I kind of wonder why Pentax sells both, actually. The 150 and 165 seems to fit pretty much the exact same role. The 165/2.8 seems to perform really well from my so-far limited experience with it.

The 150 came before the 165, it is older so it is usually cheaper.

Which kind of just begs the question: with the 150mm available, why release a 165mm? or, once the 165mm was released, keep the 150mm around?

The 165 replaced the 150.
It was supposed to be an improvement, but since I never used the 150 before I don't know if it is better or not.

I find the 150 to be very specific in its use in the 6X7 format. I too have wondered why Pentax offered both the 150 and 165. I have both, and quite frankly have only used each for a couple of shots.

As Kuronakko alluded to, the 150 was produced first, in 1969. The 165 was not introduced until 1982 and was a replacement for the 150. Pentax did not produce both at the same time. Being a replacement for the 150, the 165 was produced to be a better lens in performance. It is a fine lens.

I have the 165mm. I don't use it a lot but it is a great lens.

It is a good lens, fast and sharp.

I had heard such great things about the sharpness of the 165 f/2.8, and really wanted it, but passed because of the sync speed. For studio application, I have the 165 f/4 LS (as well as the 90 LS), and have recently been using it with great pleasure. I'm editing a recent editorial and will post those images soon.

Thanks. I was sure I've seen both the 150 and 165 being sold new. I was probably wrong, or I've seen some remaindered stock or something like that.

In any case, I'm very happy with my 165/2.8 so far. It's an excellent tight focal-length complement to the wider, permissive 90mm.

the 150 happens to be my 1st P67 lens, at USD 60 bargain price .. i bought it first coz it was such a steal, and bought a P67 body months later ... for a portrait lens sharpness is not that important, and sometimes sharpness works against you

in any case, i find the 150 sharp enough overall and i use it for most P67 portraits
