The grey F lenses are often based on the the design of the corresponding A lenses. They usually have a more eloborated optical design then the later FA lenses or the black F lenses, usually resulting in a better optical performance. Thus said I think you will have difficulties to find a better set then your 35-70 plus the F 70 - 210 (the SMC, not the Takumar of course). The F 35-105 should be okay as well. The Takumar are in most cases of simpler optical design then the SMC-Series and have no SMC coating.

According to the reviews on the site, the Takumar-F 70-210 is made of 10 elements in eight groups. The SMC Pentax-F 70-210 is 13 elements in nine groups.

So better coatings and better optical design for the SMC-F over the Takumar.

So I just ordered a PZ-1 from KEH recently as I had to send my LX into the shops again and might have to let it go if the worst happens. And I realized that I haven't used my other AF Pentax body (K-S2) for a long time after I had got a Sony a7 very cheaply, and don't have many AF lenses lying around. I currently have FA 43 and FA 31 available, and also own the SMC-F 24-50/4 and Takumar-F 70-210/4-5.6, but I left it home with the K-S2.

When I ordered the PZ-1, I also ordered a SMC-F 35-70/3.5-4.5 as my normal zoom, as this (and its Takumar-F sibling) seem to be the one of the few non-star AF normal zooms that are well regarded in the review section. However, I still feel I might need to replace some of my MF glass with my AF ones.

Specifically, I am not very satisfied with the Takumar-F 70-210/4-5.6, especially compared to my Minolta AF lenses of the similar range (now I also use Minolta AF lenses very often, so they do get directly compared directly with my Pentax gear). The Takumar-F 70-210/4-5.6 is slower than the Minolta AF 70-210/4, and my copy of the Takumar is also barely usable wide open because of obvious spherical aberration, while the Minolta one is very usable wide open, even at the long end. The SMC-F 24-50/4 is not as bad when compared to my copy of the Minolta AF 24-50/4, as both don't perform well wide open. However, the SMC-F is much larger than the Minolta one, and I have mostly assigned it as the go-to lens for the K-S2.

I currently have a Tokina-made Vivitar Series 1 70-210/3.5, but it has severe CA problems when I used on my Sony last time, and I feel an AF lens for this range is more practical for my subject of photography. I also have the Ricoh 28-100/4 P as a travel zoom, and am wondering if I should replace it with the 35-105 or 35-135 F zoom. Finally, I don't know if there are other options besides the expensive FA 20-35 and FA 24-90 that doubles as a wide zoom on film and a normal zoom on K-S2. I also want to go for the cheaper options, any further purchase are meant as replacements for my MF zooms, and I am not willing to invest too much into it. I have to consider for the bang for the buck (because of the LX that I had invested slightly too much into and might have to let go).

I would also like to know how MF lenses work on the PZ-1. Specifically, I have the K/M series, A series, and several lenses that don't have auto aperture at all (for example, a Zeiss Planar 50/1.7 originally in C/Y mount). These lenses also include a 1.2 lens, and I would like to know how focus and meter of these lenses work on the Z-1.

Any input will be welcome.

Sincerely

The ORIGINAL FA 28-105 with POWERZOOM (not the compact one) was a bit big, but was a stellar performer back in the day.

Loved that camera, in particular with the wrist strap accessory. I wish they'd bring that back. And the little snap closed pocket on the strap for storing your flash cover, etc. Handy thing.

Cheers,
Cameron

What are you going to do with the negatives? The processing you perform will guide what you need in a lens. For example, I scan any negative film I use today, so I can adjust color / contrast later using gimp.

I scan too. But I picked up the PZ-1 having photography of trains and railroad topics in mind, plus documentary in general. I still try to get SMC because the topics I work with often requires working with difficult light. I also want to have fast autofocus to help with these two subjects. However I cannot compromise too much on image quality, and I want my lenses to be both backward compatible with my manual bodies and forward compatible with my K-S2, even if I don't use it that much.

Sincerely
