Under the mirror I think 1mm could be enough. I have some kit with different kind and size. I had to use to ethanol and rub gently with a screwdriver tip and a cocktail stick:įoam. I use light glue painter masking tape to protect the opening where we see the ribbon in the top middle and the gap between mirror plate and body, so to avoid foam rests get inside: They left a mark on the back of the mirror:īy just touching with the finger, the foam crumbles: So the mirror plate with the three foam pads: Remove the mirror frame and then the mirror: The two upper ones are shorter and non-ferrous as I can't hold them with the magnetized screwdriver tip: Put a piece of thick paper for protection on the mirror: I position the body upside down at an angle, so the mirror is horizontal: Put focusing matte, fresnel and retaining frame aside, and now the mirror. The edges on the body required some ethanol and gentle scrapping stick and swab Removed the sticky gum by the edges on the top of the matte glass with a piece of cleaning paper with a bit of ethanol, and washed the matte side under tap water without touching it:

I dipped the frame first into a dilution of soap, and rubbed away some of the stickery gum, but rinsed and dipped it for a while into ethanol This is how the foam under the frame had turned over the years: Under the bracket, a brass spacer and a tiny shim under: These four screws have same size, and are non-ferrous,as I couldn't hold them on the magnetized tip of the screwdriver, but it's no problem. The two screws near the focal plane do also hold the bracket for the viewfinder. Remove the viewfinder, and there are four screws holding a frame over the focusing screen. So, if you get an old S2, don't hesitate, it's easy. S, C, S2, S2A, EC, EC-TL, and EC-TLllīesides a couple good screwdriver, I used ethanol, cocktail sticks, swabs and paper for cleansing, a bit light cardboard and masking tape for prophylactic protection inside the body, glue to hold non-magnetized screws, a mobile phone screen suction cup, and self-adhesive 3mm open cell foam.Īs I take shots for my own archival, I think it may of interest to others. The fix is explained at many places, and for the mirror the more detailed seems to be there:īronica Z, D. It's very easy, yet a couple screws were tricky to put back. Being well aware from tons of comments on the net that it uses foam to position the mirror and the focusing screen, the first thing I did yesterday before going use it, was to check that. So I bought a Bronica S2 that had no been used the last ten years.
