Hi and thank you for your comment.

This lens has no aperture blades and can only takes pictures wide open at f:1.5.
This is a M42 lens which was part of a russian night seeing combo.

Yes. Not a runaround lens... Interesting for artistic pleasures and surprises.

Everything's ok on my side.
What about you ?

It's a real pleasure to have some news about you, my friend. Very Happy

My Cyclop seems to be a lot sharper. Is an element decentered in your lens?

Forenseil, thank you for this point.
I don't know but I find it gives a lot of aberrations.
I opened it and checked front lenses. Nothing really obvious here. I screwed tightly back.
I opened the rear and found the back glass loose. I put it back and screwed it tightly.
IQ iis far better : far less glowing and sharpness improves.

I'll dismount it again to clean glasses well and relub the helicoid. Whet kind of grease do you advice ?

I agree, in the hands of an artist!

I like the first one a lot,the lens certainly has potential. Did you adjust the effect of the strong back light at all? I hope to see some more images after the CLA.

Thank you Moïra ! Embarassed

The first one was shot with the Olympus Pen E-P2, directly in JPeg.
I did no adjustment.

What CLA means, Mo ?

I quite like the images but something is wrong with the lens. Sometimes it's the that imperfections work well.

Hi Olivier, from my understanding it means... Clean, Lubricate, and Adjust, when talking about cleaning lenses.

Shake the lens and listen for a noise. Mine had the rear element loose when I first got it, but it provided the most extreme bokeh that way. Also, try underexposing by a full stop to help with the blown out bright areas. I sometimes underexpose by more if conditions allow. My last outing I was maxed out at 1/4000 and the images suffered for it.

Today was shiny, so I tried the CLA Cyclop after readjusting the infinity which I lost during the operation.
Fortunately, I stuck a scotch tape on the barrel to keep the helicoid position and managed to screw the back on place as it was before the operation.

Thx to the good topics around here, I managed to make this lens work.
Results with shiny weather.
Some spring photographies.

Shiny weather is not necessarily a good thing. How did you handle the exposure?


PostPosted: Sun Mar 18, 2012 8:38 pm    Post subject: Reply with quote

The 1st and 3rd on the readjusted focus set looks promising, I can see why you are happy with this lens......The bubble bokeh is always a favorite Smile

Yes Woodrim, you're right about shiny weather with this kind of lens.
I underexposed -1/3 to -2.
Oh, and I mounted a 67mm screwing metal hood. Smile
Previous serie (above) under grey weather shows that it's interesting for shooting such lenses.

Moïra, it is a promising lens and I'm happy that CLA worked.
It is a portrait lens. Smile
Did you notice the cat ? They like calm and tranquility.
