Cleaning a Flektogon 35mm (chrome barrel) ... (3/3)
Now, time for the big cleaning. I tried at first with the optical lens cleaning fluid, then i had to go on with the Zippo fuel. Using the "cotton fiocs" first, and the micro fiber cloth after, it has been quite easy to wipe out the haze from the inner element of the front cell ...
21. After cleaning all the lenses, i just reassembled them, starting from the rear element of the cell, and then the front one. Then, it was really easy to screw in again the front cell on the barrel, and the name ring ... The Flektogon was starting to live again ...
Since the intervention seem to succeed, the whole surgical team decided to pose for my Pentax 85mm ...
... and for the Flektogon itself, in convalescence ...
As you can see, the horrible haze has totally disappeared ... Surgery successful :-)))
... And some outdoor testing at f/8:
... and at f/4:
... and the last one at f/5.6:
The Flektogon wishes to say thanks to Rick Oleson for his advices, to Castorama (French supply store) for their cheap "lens opening tools" ;-), to the Dream Team for servicing, my Pentax-K 85 for the pictures ... and to my friend who allowed me to use her kitchen table as surgical bench ...
Note that i have put some notes on the pictures, you can see them by browsing my Flickr photostream by clicking here.
May your lenses be with you ...
In Kimi and Felipe we trust.

Congratulations on the successful surgery. It looks like you've saved a nice lens.
Hi, thanks. It is really a great lens. I have both Flektogons 35 (f/2.8 and f/2.4), but i prefer the color rendering and the bokeh of the f/2.8 to the sharpness of the f/2.4 ...
have you figured out how to take the focus ring out?
No, luckily enough i never had the need to do it ... But i think i saw somewhere on the net some service manuals ... Will check my links ...
..i own similar lens with similar issue...great thanks to you ...a superb job done! Kudos.
