This is just a great lens! It has many advantages that you will never get in any other medium format lenses:
1) It is fastest portrait lens for a such medium format frame size. There is other faster primes but they are all intended for a smaller frame size.
2) 10 blade aperture. It helps to gentle blur background for smoother bokeh
3) Built-in hood
4) 67mm filter thread which is more common that 77mm.
It has only one negative side -- its weight too much for me. Anyway highly recommend!
Pros: Excellent IQ
Cons:
Sharpness: 9 Aberrations: 10 Bokeh: 10 Handling: 9 Value: 10 Camera Used: Pentax 67
I used this lens (almost) exclusively on my uncle's old Pentax 67 camera for a couple weeks. I can't give an accurate value estimate because he bought the system + three lenses for a couple hundred dollars second-hand.
Positives:
-really standout IQ
-surprisingly light for such a long lens
Negatives:
-"Auto" switch easily slides back to manual mode and needs to be re-cocked. This took a while to get used to, as when it's on manual the built-in light meter doesn't work.
Of the lenses in his kit this was by far my favorite to shoot with. It's an awesome focal length on medium format, and the aspect ratio fits the field of vision really well. It's also worth noting that it's not the easiest lens ever to focus. I realize this is mainly a fault of the Pentax 67, but if you're shooting at f/2.8 focus is very hard to nail. Despite that I think it's an amazing lens and I would highly recommend it.
I really enjoy shooting with this lens. I admittedly have only put one role through it and have not closely scrutinized the photos -but I'm not the type of guy to peep. The images have come out great with excellent sharpness and contrast. The value of this lens/system is second to none. My other lens in my kit is the 100mm f4. They pair nicely together where the 165 is great for portraits, the 100mm is better for surroundings. I'll be picking up a 45 or 55mm in the future and I think my kit will be complete.
Pros: Handy F2.8
Cons: Random loss of contrast
Sharpness: 9 Aberrations: 9 Bokeh: 8 Handling: 9 Value: 10
I like this lens. It pulls up shots I thought wouldn't have worked out. I tend to shoot in low light, hand-held, wide-open and sometimes back-lit. Out of a dozen or so times I put this lens on for color shots, I had two images with a degree of loss in contrast due to side lights getting in, but still I got a usable image. In dozens of black & white images it was easy to use with no signs of problems. Kodak Ektar looked good as well as a few rolls of Portra 160NC looked equally good. I think that this is a little more prone to flare issues and the built-in hood is only half adequate. Otherwise... "I like this lens"!

The 165mm lens is one of the main reasons I bought a P67. It's the same angle of view as a 85mm lens in 35-mm format, my favorite! It's very sharp. I try to use f/5.6 or f/8. As mentioned f/22 is not going to be optimum in any MF lens. I do urban landscape and handhold it a lot. I try to use 1/500 shutter speed.
