PLEASE HELP: Assembly problems with SMC Pentax 50mm F1.2

Great Thanks for the trick DCShooter and thanks a lot to all helpers.
I fixed it for a little bit. Now close focus is at near 0.53 m but not at 0,45.
For me itīs okay and I decided to use it like this. Maybe I fix it later but I think Itīs okay for me to have 10cm lost.

Here are some more examples
1) F1.2_at infinity
2) F4_at infinity
3) F1.2_at infinity
4) close focus (about 55cm) @ F1.2
5) close focus (about 55cm) @ F2
6) close focus (about 55cm) @ F2.8
7) close focus (about 55cm) @ F4
8) close focus (about 55cm) @ F5.6

Hey,
here is a step by step assembling of the 50mm F1.2 lens. I did not know where the failure is but at the end I did get near infinity but no close focus at 0.45m, just up to 0.6m (see pics).
The last pictures are taken with K3 at infinity (F1.2 - F2 - F2.8 - F4) and at close focus (F1.2 - F2 - F2.8)

Hey Pentaxians,

I bought a cheap (? 250€! ) 50mm F1.2, unfortunately with a lot of fungus inside.
No Problem for me, I thought. I often dissambled and assembled manual pentax lenses but never had this problem:
I never put out the lens barrel. So now I have to re-calibrate and adjust the lens.
Never did this before and I tried so many positions but not get it beack to basic settings. :(
I thought measuring the distance from top to back would be alright. Otherwise I used a white marker to mark the transitions - i forgot it. I forgot to make fotos too ;):(:(.

BUT: the lenses are free of fungus now :D.

Can someone please help to assemble the lens? Some tips and tricks? are there special positions of tubus/lens barrel too look for.

Pictures would help a lot, if possible.

If I will get it back to genuine settings, I will Dissamble the whole lens again and make fotos of the complete Dissamble/Assemble for all Users and the Dissambly Data Base.
So every tip and trick you will give is a great help for everyone.

If someone will not give these information to everyone, please write me a PM. If you not want to have published your knowledge let me know also, and I will conceal the information to adjust in the Dissambly Data Base.

Great Thanks to all Answers,

Milka

I have one more Question:
for working with manual lenses I have to add the focal length. Do I add the focal length of the lens (for example 50mm) or do I have to add the focal length with crop factor of 1.5 (for the 50mm its 75mm on 35mm equivalent) ????

Thanks for your answers.

Great Thanks to your attendance. I will try all the inspirations when the next clear sky is coming.
Maybe there is a little trick in calibration. If there is one - I will try to find him =). I will let you know =)

I donīt know. I used several types of the AAA-Batteries available in Germany and I always used new ones.

I calibrate it like the screen. I rotate it overhead 180° first, than 180° horizontal and than 180° vertical (left to right).
Not always this way - I tried to switch the positions , but it does not work. Did I something wrong ?
It was working 1 Time, so I think it can work... but Iīm not able to use it right :(


Like the screen, but I think it is the same in the manual, isnīt it?


If Iīm using Manual lenses, should I chose the focal length of the lens before calibration? Should I calibrate for each lens after chosing focal length? How is it with non-Pentax lenses? did the O-GPS1 accept these lenses at its algorithm?

Hey Pentaxians,

I need some help. I did not know what to do anymore.

I have the O-GPS1 with K-3 for about 1,5 years and I tested it so many times.
On wide fields where nobody goes along - in the city - ... with tele lens - with standard lens - with wide angle -... nothing!
It just worked 1 Time !!!! for about 2hours.

What can I do right OR what should I put attention on.

How is it right to calibrate? Is there any or just ONE right way to calibrate?

I want to use it for astrotracer with Pentax 50mm f1.4, Sigma 18-35 f1.8 Art and maybe with Samyang 10mm f2.8 and Porst 135mm f1.8 or Pentax 200mm f2.5.

Are there any limitations in usage?!? Is the time limited like shooting stars without O-GPS1 ?!?

Please let me know you Pentaxian-Pro-knowledge before the stars come out again =).

If the answer was still given in a thread I did not know, please let me know that. We donīt need to discuss the same problem again.

Best regards and Thanks for all anseres,

Milka

Thanks for the link.

@vonBaloney: I already use this settings and as you can read upon it works with Pentax-K SMC 50mm F1.4.

Do you think I need a "Pentax K to Pentax K-Adapter"?!? or can I buy a plate you telling about @aleonx3 ?

Just 60€, On K1000 itīs working well, even with aperture.
On the K-3 the aperture is even wide open when press the shutter or the aperture control button,or by pressing the green button for lightmeasure.

So It is not a problem of the lens, I think.

@aleonx3: Did you use the same lens (aperture F1.2-F16) and the K-3?

Thanks for answers.
