Synchro COMPUR mechanical shutter module has found out in my junk box the other day, remembering me of good days that I had been accustomed to 4 inch by 5 inch format of silver salt film over 30 years ago. This shutter module had been replaced into alternative Seiko because of unstable operation. Probably some rust of staffed lubricating oil sludge must had caused the problem, so I'm going to disassemble to maintaining this fully mechanical shutter construction, of course sophisticated keen finger works would be required to carry it out and ST and SST would be required on the way, but I will do it being supported by the experience and the technology that I established while overhauling Leica M3 including range finder block full disassembling and re-adjusting including diopter of the distance measuring instrument construction. The shutter module is sandwiched by the anterior and posterior lens elements on the shutter board when actual use. I'm going to use this ancient lens board on the digital body in very near future to reproduce the performance of the old German Schneider large format lens. Long time of period has passed already that is enough to forger me the familiar lens name.

21 years old first generation BC7 SUBARU Legacy Lsi US model had overcome thoroughly a critical failure in the automatic trans-axle rear transfer clutch mechanism, I didn't do anything on the problem but switching on and off the wiring to activating solenoid valve while highway running. Probably, stepping wear at sliding groove in clutch bell must have been smoothed by this primitive experiment. As a matter of fact, any strange reaction has disappeared like nothing that is popular among the similar model user, tight corner braking phenomena. Childish but logic countermeasure with compatible with flash has taken effect, so, layman's idea should not be ignored. By the way, how shall I do on the replacement full kit parts of clutches at my hand now?
I drove up to Mousi from Sasayama rising up from Northern slopes, there were several frozen places, I could have arrived at an usual restaurant, "Sugar" at ease on BC7. I make it a rule to visit to see managers and to enjoy with them who are very friendly and talkative with the visitors, though I did over-ate myself as usual.

I found out old lens by chance in my junk box, Elmarit-R 135/2,8 with fault defect in lens element, peeling balsam extensively. Giving up to use this without any experiment, I checked it comparing with another l35 lenses, Minolta TELE-ROKKOR-PE 135/3,5 and Hektor 135/4,5 at 6,3 aperture. No inferiority can not be used without any fear, the result obtained made me determine to continue this old lens from now.

The first generation Canon EOS Kiss Digital kit zoom lens 18-55/4,5 deserted by my son has enough physical performance for me. So, I decided to use this small and light toy like standard zoom lens as an ordinary normal device.
According to inviting this genuine lens, basic ritual I have been going so long must be changed because of all automatic system provided on a sophisticated recent camera, auto-focusing, auto-iris-closing, cognitive-focusing. I'm going to be a coward photographer on earth?

Among them, automatic ISO value adjusting system is very convenient for me avoiding too slow shutter operation leading to camera shake. Thanks to the noise reduction researches on the imaging area by the factory engineers, I can shoot without any fear of miserable results. It's like a different world for me like looking up sun rise!

Also, an old Leitz Macro Elmar 65/3,5 would be carried about in the same manner that had been modified to adopt onto EOS mount while the silver salt film period. As it is designed only for Vizo-Flex system, some focusing device is indispensable, helicoid ring or focusing rail, so I did it by utilizing Asahi Pentax K mount helicoid ring and T-mount adapter for EOS. Of course, infinity position is established by just adopting on the decided lens back distance.
In addition, 42mm Praktica screw mount Carl Zeiss Sonnar 85/2,8 HFT is available on EOS, smaller and lighter character but with favorable performance makes me satisfy as a good one.

New comer Canon EOS 7D has not a few developed functions compared with old 10D, especially, 100% field view ratio is above a word finding out no reason to return to old one. Functional button switches are almost the same, though many additive are observed. Smaller mirror situating just frontal part of CMOS sensor with 45 degree angle has influence a little, that are arranged to accept EF-S lenses with shorter lens distance. Thanks to this modification, old zoom lens deserted by my son is acceptable for new body and probably I would use it. An experimental comparison, Canon EF 50/1,8-2 and Minolta Rokkor-PG 50/1,4 revealed the superiority of ancient model even now as mentioned in various reports. The price of 7D was just 1/3 of 5D Mk3. From some different standing point of view, APS-C that is smaller than full size, has a unignorable advantage instead, suing some better area if the lens that is designed for full size formatting image cutting of the inferior end part. This way was often the case I had been utilized since the silver salt film period, Hasselblad Carl Zeiss Planar 100/3,5 was set on Mamiya 645 1000S focal-plane shuttered model. Now I'm enjoying photographic hobby in the same way on Digital formatting image.

Finally I selected Canon 7D digital body for the next choice as a successor of 10D that had been used as long as 11 years. I have been at a loss which to choose, 5D Mk3 or 7D, I have wiped out my hesitation. The least modification in digital signal, want I reproduce the scenery by means of original lens physical performances. Though I know that it's possible to change the way of expressions by means of digital signal image processing, I dare put an emphasis on the Leitz theory, "Kante". My brain cortex must have be hardened with modification?
