Favorable tomorrow?

I'm afraid if it will rain because I have a planning to go out for photo shooting to Hattori Green garden tomorrow as a regular training held by my class. As a bitter experience, shooting in a rainy condition, Tamron 28-200 became a void because of cloudiness deep inside of the lens component. Some rainy condition produces an extraordinary good result, so I hear, but I would like to refrain from participating the group shooting program. It happened last time the event at Itami International Airport shooting, though I appeared at the station of meeting place, I didn't accompanied with them trying it next day privately. Bitter experience prevent me from shooting in sever rainy condition. It's very troublesome task to maintain and to disassemble especially Zoom lens inviting hard work with many lens component. Several zoom lenses were maintained with disassembling thoroughly by myself, this procedure is required periodically to keep their original performance for every camera lens no matter how it is fixed focus lens or Zoom lens. By the way, I dream a worst dream in Minolta MD latest model, front lens unit and rear one are molded in one piece with Engineering Plastic resulting a disposable item. In case of necessity to be disassembling because of mold or cloudiness or both reason, most of the engineer will give it up as I had been so. But careful experimental trial I did proved a gospel only on front lens module disassembling procedure. The vent plastic tag for front lens is removed mechanically with the best care and concentration, then front lens of front unit would be removed by moving it parallely with lens holding wall, next ones would be removed one by one with out specific effort. All the lenses are set as they were after cleaning, then what will become of the most frontal one, holding nail construction had been destroyed and removed? As a good and convenient constructive designing, the nameplate ring would be the fixer of the front lens unit, all of them are tightened with this final procedure. Though this description is described on MD Rokkor 50mm/1.7, the construction would be the same if the production period time are the same, such as MD 50mm/1.4. As for the rear lens unit component maintenance, because there would not be tightening mechanical construction, any glue would be invited as shown, Pactra Aero Gloss is one of the recommendation, easy to soften and to remove by applying Acetone.
