Minolta SR 58/1.4

Minolta SR 58/1.4Before mirror-less cameras are not prevailing like today, Minolta SR lenses were thrown away in the market being sold as nothing, even MINT conditioned one had a price tag 1000 yen. As we knew, the flange back value of Minolta SR is the shortest, 43.5mm, on the other hand that of Canon EOS is 44.0mm, resulting no way to focus on infinity point if SR lens is mounted on EOS, it's an inevitable physical disadvantage.
This is why Minolta SR lenses were sold away at the cheapest price in the past. Now, mirror-less cameras have capability to accept SR lenses by way of SR lens adapters.
To tell the truth, lack of flange back value 0.5mm on EOS camera, is enough compensated by adjusting the helicoid adjusting construction.
Once I had experiences to modify SR lenses for adapting on Canon EOS body applying the same principle on them.
Minolta SR standard lenses modified for Canon EOS body.
As all the camera manufactures were advocated in the designing especially on standard 50mm lenses. So the designing had been established 40 years ago and the constructive designs are not changed even now.
All the Minolta SR lenses I'm keeping with Canon EOS bayonet mount has the capability to focus up at infinity position.

Hi-spec PC came to me

Hi-spec PC came to meHi-spec PC was obtained and it works very well, it is a second handed one from my son, he has moved to Mac PC the other day.
Windows 7 program is in SSD and start and access are so quick as to twice as I had used.
I made up my mind to restore and clean up mine this time after back up process.
5 years interval made me forget the BIOS setting up procedure, it is often the case. Without jumping on CMOS clear terminal, CDR drive and HDD at all in the BIOS picture.
HDD is replaced because of some strange noise by the arm moving function, it must be the symptom of mechanical fracture inside. This is why 1.0 TB HDD is replaced new.
I don't prefer to use Note PC because of basic delicate mechanical construction, especially CPU fan, the fan drive shaft lubrication. The depletion of shaft mounting parts means the life of Note PC life. On the other hand, ATX tower PC has enough flexibility to maintain and to repair any time the user wants.
Before that the scale of CPU fans differ fundamentally leading to the potential for CPU cooling function, however the size and bulk might differ each other, the reliability is the first when PC is used for job purpose.

Important tire pressure

As I mentioned in the last blog, my son ran about all over Hokkaido few days ago spending a week by means of his car, Honda Step Wagon wearing all wheel drive construction. According to his opinion, in spite of tire pressure checking as to be 240 kpa for front at Osaka before departure, he could not drive it with certain stability. Luck of tire pressure there was the reason, then he adjusted them following the caution decal adequately. On the other hand, he felt some inconvenience on tire pressure after coming back to Osaka, too high pressure here.
The comparison of atmospheric condition, about 10 degree in Osaka, minus 20 degree in Hokkaido shows a fundamental physical difference, 30 degree is the factor for the vehicle's safety not to be lost.
As for my car, I make it a rule to check and to adjust tire pressure as a periodical maintenance every month. On my perception, 10 degree Celsius temperature causes 13 kpa fluctuation.
Deeper consideration leads us to the conclusion that an only surface to contact with the ground is nothing but a tire touching plane just the same as post card, however high performance car it may be.

Relieved

RelievedAt last his landmark appeared safe on the Google map around Noto, probably he will arrive at Suruga tonight 8:30 and he will take an inn there starting up tomorrow morning to Osaka. Young people does not count "Fatigue" at all.
All of the motorcycles used by his group are computer controlled, the reliability of the machinery is established safe mechanically and electronically. They started this trip without any doubt on their equipment and almost coming back safe without any trouble.
I feel now again that our confidence of industrial product is above all in the world.
Then, the means of our land protection should be periodically improved qualitatively especially in sea defense however threatening might happen in our exclusive economic zone. We had better take best care not to be suffered by any troublesome neighbor countries. Inner military fighting might happen soon?

Worry

WorryIn spite of watching my son's position on Google map, it does not move showing a marking 7 hours ago. Though I checked some accident such as Ferry collision or motor stop on the sea around Tomakomai, no report is found in the Web site, how come? It is true that his i-phone is not sunk in the sea because his positioning mark appears clearly. Anyway, my son does not stop to make me suffer, this situation will continue even if I might go to Heaven.

As I determined to desert all of my passed history last year, I had refrained from contact with my intimate friend including New Year Greeting cards.
Several cards sent to me this year remind me back my good young days, hot and active filled with energy and they make me contact again to know heir recent living style including healthy conditions. So, I'm going to write post cards to know their E-mail address.
