Welcome to my page and thank you for looking trough my listings !
I service professionally any vintage lens.
This is something I do in my spare time , for many years, no matter of make and model.
I do this driven by my passion for photography, for vintage lenses , and so you guys can enjoy a vintage glass on it's full potential, without having to worry about the issues that an 40/60/70 years old lens has without being service.
This listing is for a Petri CC (colour corrected) 28mm f3.5.
I have modified/adapted this lens to M42 mount, replced the petri mount with a custom made M42 plate. I have also buffered the rear of the lens to compensate for the gap left around the M42 mount and rear optical block.
Due to the adaptation, the auto aperture function is cancelled. Obviously you can set the aperture manually as usual.
The lens is Calibrated to reach infinity.
The lens has been fully serviced by myself (I never service a lens partially ) , completely disassembled, every little part has been cleaned, washed, polished, re lubricated.
The washing process , with detergents, not only helps for a nice and clean look of the barrel, getting all the dust out, but it also eliminates the risk of any fungal traces/spores may exist on the parts.
I use a very high quality grease for my lenses, homemade by one of the ebay members. You can find his grease here on eBay.
The focusing mechanism works as it should, nice and smooth.
Mechanichally everything works as it should. Perfect clean and dry aperture blades.
Optically the lens is in good condition, there are no major scratches , no haze, and obviously no fungus.
There are two marks on the front element , you can see tjem in the photos. In reality they are not so visible, for the photos of my listings I use a macro lens and strobes to show all the details of a lens I'm selling. This marks don't affect the photos, I have used myself this lens for few months , it performs exactly as it should.
All the optical elements have been cleaned, treated with my "special cream" for potential fungus traces and also expised to UVC light.
The barel as you can see in the photos is in good condition, there are no damages the barrel , just normal paint wear over the years.
Please check the photos as they are part of description and feel free to request more photos.
Sold only rear and front caps.
Please feel free to ask any questions or requests samples taken with the actual lens.
Happy to post outside UK.
Thank you for watching !
