Completed Minolta Rokkor TC 100/4

Taking relatively long time to re-set 13 iris blade in the adequate position, finally I have succeeded in completing fairly well. Though the construction of this old Minolta lens is merely Triplet with less correction of aberrations, less grass materials and less number of reflective surfaces make the light signal easy to arrive at the imaging surface, leading to purely transparent and clean pics. Clean and transparent light source or well corrected light signal by sophisticated computer analysis, which is the better on Earth? Old lenses have some disadvantage compared with recent designed and expensive ones, less picture quality when used at iris fully opened position, flare, halo and ghost are the criminals. On the other hand, such kind of disadvantages might be utilized intentionally, as some specific Physical properties those are not contained in recent ones. Shortage might be changed into specific advantage, depending on the intentions of photographers.
