Tamba-Sasayama was the destination today, it is my mother's birthplace, very often visited I did while she was in this world. Sasayama Isonomiya-Hachiman Shrine was the main target today, in addition, Kotohira Shrine at Shimosasori was visited on the way.
Continuous 6 hours drive made me exhausted, I feel I have aged.

Along with Prefectural road #603 from Ikeda to Nose I visited two shrines yesterday, Yasaka and Dazai. Traffic was so smooth at all.
All the things would go well to better from today, if secondary explosion would not happen.
I would like to make it a rule to take a walk for 1 hour before NHK Radio Gymnastic program, of course my favorite camera is on my neck.
While these stable days studied I the very special circumstantial condition, having nothing, no connection and no relation.
The things became clear those are necessary to live actually.

Tightening pressure has been released gradually these days, looking at the world, atmospheric condition is changing into blue sky.
Probably, dealing conditions would be recovered at least in the middle of this month. "The mountains have brought forth a mouse." might be the result as a matter of fact. Though the Authority insist to stay at home now, very few would follow the declaration in future, an ordinary condition would be regained in the beginning of the next month.

In spite of the manufactured date, over 50 years ago, Konishiroku Hexanon 45 mm/f 1.6 lens performs well and it's capability is not the second to none including recently designed standard lenses. Unpredictable potentials in this one could be withdrawn just only specific condition, Digital image sensor, Mirror-less body with live view EVF with enlarged focusing pin pointing.
Especially, brilliant image f 1.6 iris fully opened condition, focusing capability of SONY Alpha 7 plays a good part of shooting machinery. Relatively easily ”Bokeh” controlling is obtained with minimum endeavors if lighter lens is supplied. This kind of dreamy situation could not be imagined by the designers and the engineers belonged with Rokuoshya and Konisiroku company 50 years ago.
As for Hexanon 45 mm/f 1.6 lens, it must be surprised itself and is trembling with pleasure because it can exert it performance and potential utmost now instead of being deserted into a trash as a void.

2 pieces of Konica Hexanon 45mm/1.6 old lenses are prepared for modern use inviting SONY E-mount. Prior to the modification much deeper consideration was done to make use of the original functions as much as possible. Remaining straight helicoid focusing function is the task this time. As the superb performance of Hexanon 45mm/1.6 has been already known by preliminary trial shooting by myself, the work proceeded aggressively this time.
The relations between controlling ring and helicoid outer ring in combination with the infinity position was established without exaggerated efforts at all on SONY E-mount.
Residual problem to invite original straight helicoid function should be solved by some external parts setting, two ball bearings fixation for eliminating slipping resister on leading and trailing movement.
Putting a guiding pole on inner helicoid and supporting 2 ball bearings on the inside surface of the bayonet mount case. The slipping surfaces causes resister especially on this case, translating from rotating movement to sliding straight movement, this is why I determined to make use of miniature ball bearings here.
Avoiding Slip resistance and inviting Rolling resistance is worth doing, because the smooth feeling would performs compensation while the excitement and disorder in shooting scenery.
Now, the fundamental performance on SONY E-mount is establish with rotating helicoid function, straight is not yet. Just putting guide pole and 2 ball bearing so adequately would finish the work, that requires keen & precise concentration with shoulder stiffness.
