Minolta MD Zoom 100-300/5.6 cleaning

 Not so busy but not so free condition while Bon-holidays made me determine to disassemble the lens unit thoroughly in Minolta MD Zoom Rokkor 100-300/5.6 into the depth of zooming lens unit inside. Though the performance had been recovered enough by cleaning front and rear unit to satisfy my requirement under the condition of Photoshop application program, very slight mist in the zooming unit that could not be cleaned until disassembled completely was there. After some interval to be at a loss which way to choose do or not do, I came to the conclusion to proceed the way however difficult and however much barrier might exist on the way. I have realized after doing that the number of constructive parts are not so many and relatively easy to reassemble with precise optical adjustments such as iris closing position and final infinity position, boring time today will be killed by this complicated reassembling procedure of this Minolta Zoom lens.
