The Best 50/55mm Film era prime lenses

**MilkaSchokoHase87** · 09-15-2018, 12:28 AM - **3 Likes**

Hey pentaxians,
I finally finished my collection of All 50\55mm Film era K-Mount prime lenses. (no macros = These I will test later themselves).

So now I am open for ideas of testing and comparison of These lenses..

After that I will test them and report some reviews.

Actually my Favorite is the A 50 f1. 2, but lets See IF this lens is the Best one.

Here are some pics.

Greetings,
Milka

You are half way there. Next step is M42 lenses .....

Of these, the Auto-Takumar 55mm 1.8 zebra and Super Takumar 50mm 1.4 eight element lenses are must haves.

Right you are.

Boy o boy - F50mm 1.4 versus F50mm f2.8 - now that is a showdown (sorry - the K50mm 1.2 is a no show at that level

)

But to be fair to the question posed, it is a tough task to 'test' these and come to a rationale conclusion. Each has their strengths (and weaknesses). But, as indicated above, I am a sucker for F glass

this is for Pentax only lenses?

**MilkaSchokoHase87** · 09-15-2018, 02:15 AM

Yes, pentax k Mount only and without macros. Sorry tabz

IT is because the macros themselves have a great Image quality. Its just interesting which macro is the Best. But it is not necessary to compare a macro to a standard prime, I think.

What is your definition of best?

**MilkaSchokoHase87** · 09-15-2018, 02:35 AM

Best results in sharpness, contrast and abberations.
My idea was to test it in Lab conditions with a test chart an in field. Close focus and infinity. Minimum and maximum aperture as well as sweet Spot.

**GUB** · 09-15-2018, 02:35 AM

I have most of what is there except for the 1:1.2s (I have a Rikenon 55 1.2 instead). Also tak 50s and 55s including the 8 element. In general my go-to one is the A 50 1.7. A dependable workhorse when stopped down a stop or more and just that little bit of art wide open. And not so irreplaceable should something happen to it in the field. If you do objective comparisons of bokeh etc I think you be disappointed in how similar they all are! Apart from the obvious difference of widest aperture.

**GUB** · 09-15-2018, 02:39 AM

I will be interested in how sharp the 1.4s are when stopped down a bit in comparison with the 1.7s. My gut feeling is they are not quite as clinically sharp at say f4.

**MilkaSchokoHase87** · 09-15-2018, 04:40 AM

My A 50 f1. 2 is very sharp from 1.8

**sergysergy** · 09-15-2018, 06:40 AM

beautiful collection!

kevinWE · 09-15-2018, 06:59 AM

I use my M-1.7 quite often. I find it sharp enough and aberration issues are easily corrected in PP, but I rarely have big issues with aberration.

All Pentax film era 50/55 lenses? I think not. Where is the Pentax SMC 55/4 or Super Takumar 55/3.5?

**MilkaSchokoHase87** · 09-15-2018, 01:59 PM

K-Mount lenses? I never Heard about them and they are Not listed in the data base
