I cleaned the lenses in a bath with a drip of dish washing solution and destilled water, in a ultrasonic cleaner. After waiting 10 minutes to let it warm up I tried again and it came off without an effort!
I removed the other lens (that ring came of easily) and put the element in a warm water bath, about body temperature.
the the ring that secures the last lens of the back element didn't come off. I managed to take all elements out and cleaned them, because there also was some dust and a small hair visible. The fungus sat at the edge of the outer lens and it came off without a trace. I took a 110mm Sekor Z lens apart because it had some tiny fungus in between the last element (facing the camera). Just for the search engine, because there is already some good information in this thread. Oh and having some great music going in the background so you completely forget what time it is. Most important, a clean soft work surface n good light. Rubber plugs, rubber straps, belt clamps, lens vice, 3rd hand, thread chasers n taps, micro drills, a few types of dental picks, hemostats, forcepts, scalple, q-tips, suction cups, screw organizers, a good loupe. I made my spanners individually to fit the specific lenses I am working on instead of using an adjustable generic spanner. Good set of screwdrivers is formost, good spaner n some mechanical intuitiveness. an urban myth.Īs for tools needed for lens work. it will disolve the paint and will have to be reblackened. Watch out when cleaning lenses that have edge blackening. Vodka is not good and will leave a residue, it will only make your job miserable unless you are drinking it, then you won't care what the lens looks like in the end. Good air circulation is also recomended regardless of which alcohol you choose you use.
#DISASSEMBLING OM SYSTEM LENS SKIN#
Wearing gloves is recomended, it is toxic stuff and is systemically absorbed and will defat the skin which can cause long term damage. the chemicals don't leave any residue since they evaporate just as fast if not faster than alcohol. Denatuered means it contains certain other chemicals that are just as volitile as alcohol to make it undrinkable. Isoprople will do just as well AKA gas line anitfreeze. There are other names for it in other countries, but here in the US, it is called Denatured Alcohol. If you've seen enough of these lenses, you'd know by sight exacly how it opens.ĭenatured methanol alcohol is the same stuff used to make shelac, sold in paint stores.
#DISASSEMBLING OM SYSTEM LENS INSTALL#
Some have screws under the rubbler finger grip strip on the sides, some have screws hidden under the thumb grips that get removed n access holes to the screws, the soft focus lens the entire front comes off to install disks n the access to the front cell is simple, floating lens style lenses need to disengage the floater lever n that will require realignment when assembling it again as well as clenaing all the elements inside the floater cell n relubing the helical, some lenses require removal of the name ring on the front n unscrewing the front cell like a light bulb. Not knowing which 150mm lens you have, not all are created equally.
