Hexanon 45mm/1.6 Superb standard lens

Hexanon 45mm/1.6 Superb standard lensProbably my last work, Hexanon 45mm/1.6 lens is now undergoing for transplantation. The donor is Konica S-1.6 old range finder film camera produced over 50 years ago, and the Digital format camera is Sony Alpha 7Ⅲ full size flame with E-mount.
Disassembling and removing lens unit procedure had been done with desperate concentration and doing on lens unit to clean lens glass and iris blades in addition to removing out all the mechanical shutter unit with slow governor and slow timer leading to 60 gr weight reduction.
Physical positioning of helicoid construction makes it possible to reproduce all the barrel alive on Sony E-mount this time. The weight including new bayonet would come to be about 200 gr in total, helicoid outer lace, guiding outer ring, iris ring and shutter speed ring and front decorating ring are all made of brass material as a matter of fact.
Hexanon 45mm/1.6 on Sony E-mount would be regarded as if it was easily removed and just put on the mount without any difficulty. No complicated scaling and calculation were not required? No precise processing by technique is necessary?
Anyway, straight helicoid system and full barrel reproductions would be attained this time.
I'm looking forward to shooting photos with this lens, trial fitting test has revealed fine performance already, to tell the truth.
5 group 7 element lens construction will exert a great performance with superb transparencies!

Wrangler Rubicon Thrust adjustment

Wrangler Rubicon Thrust adjustmentToo consistent nagging complaining about the stability while straight running on Wrangler Rubicon obliged my heavy hip to move the action, it is simply called "Parent Baka Chanrin".
He must seek the way to solve the problem like this as I had been making efforts in this field.
The standard value of wheel base for 2-door Rubicon is 2458.72mm, 2456.0 for the right and 2457.0 were obtained promptly for actual scaling, so right side wheel base was extended as to the same value on the left side. Calculation shows 2.3 minutes angle value discrepancy, it is within the tolerance at all according to the European Traffic Safety Standard, but he complains, so I feel worse.
Consequently, upper and lower trailing arm hinge bush holding bolt and nut loosening method was invited. No blacked long hole adjustment was required, just moving the inner lace of bushes was enough to adjust this time.
Unpleasant handling as my son declared, ugly wandering with bad taste, relatively shorter wheel base and wide tread enhances the tendency at all.
All the bad habit disappeared as if nothing had been happening, after adjusting with trifle attitude so effective to settle the crying child so calm.
I have realized the importance of "Zero Thrust Angle" in any vehicle not only for comfort but also for safety.
Vehicles in Japan Left side going for Auto mobiles, with Plus Thrust Angle is very dangerous because it will collide face to face if a driver might fall asleep, this truth and fact should be known by every driver.
