    Petri 55mm f/2.0 CC lens aperture repair

    Over the last few months I’ve bought a couple of Petri or Petriflex cameras and one of them had a Petri 55mm f/2.0 standard lens with a few problems with the aperture blades. Since I recently had another lens apart to look at an aperture problem and therefore ‘have my eye in’, I thought this might be a good opportunity to fix the Petri lens as well.

    Broken Agfa Color-Telinear 90mm f/4.0 aperture repair

    Last year I bought an Agfa Ambi Silette 35mm rangefinder which is unique in the silette range because it has interchangeable lenses. At the time it was manufactured, there were a series of lenses made for it, but when I purchased my camera it came with just the 50mm standard lens. I’ve been on the look out for a reasonably priced copy of the 35mm wide angle and 90mm portrait lens, but haven’t been able to find one, until a...

    Auto Takumar 55mm f/2.2 strip down - blades assembled in the aperture

    Strip down, clean and lubricate an Auto Takumar 55mm f/2.2 M42 lens

    This post describes my experiences stripping down, cleaning, lubricating and repairing an M42 mount Auto Takumar 55mm f/2.2 lens which dates from about 1958. I acquired the lens as part of a purchase of a Pentax S1 35mm slr which had the Auto Takumar fitted as a standard lens. The lens looked in pretty good condition all round apart from a problem with the aperture. The lens wouldn’t stop down using the aperture ring although if I moved the actuation...

    Miranda 50mm f/1.9 cla - job complete

    Miranda 50mm f/1.9 focus thread clean up.

    Last week I took ownership of a Miranda Automex III 35mm film camera fitted with a Miranda 50mm f/1.9 lens and found that the helicoid was in need of re-greasing. I have already rebuilt the aperture on one of these lenses and found them easier than most to work on, so I thought it would probably not be too hard to re-grease the helicoid as well. The following is a pictorial guide for anyone who may find this useful. The...

    Miranda/Soligor 50mm PAD lens strip down 1

    Miranda/Soligor 50mm PAD lens strip down

    I posted last week about the Miranda D-r 35mm SLR I bought from eBay and the condition of the Miranda 50mm PAD lens which was fitted to it. In short the aperture was completely frozen when I received the camera, but started moving after it had warmed up a bit in the house. However, looking at the aperture through the front of the lens it was obviously covered in a film of oil and after a few days the blades...

    Helios 44M focus thread cleanup - lens

    Helios 44M focus thread cleanup

    This post describes the procedure I used on my Helios 44m prime lens after I discovered the focus ring was sticky and gummed up with old grease. The pictures which accompany  this procedure are shown below as a gallery. Helios 44M focus thread cleanup images Background I recently acquired a couple of these lenses when I bought a Zenit EM and a Zenit 11 35mm SLR which had these Helios 44m fitted as standard lenses. They are very useful lenses to own...

    Carl Zeiss Jena 50mm f/2.8 strip down and clean

    I received another camera and lens combination a couple of days ago – a Praktica LB fitted with a Carl Zeiss Jena 50mm f/2.8 zebra lens. When I received it the focus ring was completely locked and the aperture wouldn’t close so this seemed to be another ideal candidate for a ‘strip down and clean’ post. It turned out this was a considerably more complex problem than the last lens I took apart and cleaned although I’m pretty sure that it’s...

    Stripping and cleaning a Pentacon electric 50mm f/1.8 2

    Stripping and cleaning a Pentacon electric 50mm f/1.8

    This week I made another purchase for my Nex 6 in the form of a Pentacon Electric 50mm f/1.8 prime lens. It actually came attached to a Praktica PLC3 slr which I purchased as ‘For spares or repair’ from e-bay for £13. When I received the camera I found that the description was quite accurate! The body is in reasonable condition but the shutter speed selection and the iso setting are not working properly, and when I tried to adjust...
