Things move
The climate change happens immediately after "Higan", Autumnal Equinox as usual, we have cooler morning today. True Autumn season comes now, so I feel. In spite of good season as it is, our attitudes are quite restricted by the annoying invisible object.
I returned work after 3 and a half year interval because of one of a stuff absence. The name of his illness is ”Sudden deafness" mainly caused by some mental illness. So, the stuff might have difficulty to come back to the same work?
Then my happy daily life might be hindered though it has been like a Dragonfly in the Paradise. Anyway, things will be cleared this weekend. Some of my hobby lesson might be inhibited at the worst?
Fujinon-ES 75mm/4.5 lens for DPE processing took effect at the small flower shooting outside scenery. 5 to 10 mm small objects are available for shooting though close up difficulty exists, object's moving and thing focusing depth. It's a completely different world from an ordinary shooting situations.
Though it was obtained in NOS conditioned at 1,000 yen in Yahoo auction few years ago, no damage like mold or cloudy was observed, no helicoid construction but iris from 4.5 to 22 is compensated by straight sliding focusing mechanism.
It goes without writing that all the inner surfaces are reinforced with black non-reflecting blanket without failure, long lens barrel often unpredictable reflection leading to flare and ghost mischief. This countermeasure should be performed without argument.
Putting the lens module at 250 mm forward position from the imaging sensor, more than 3 times magnification could be obtained. The potential of 20 shot per a second is a good help for actual hand holding shooting situation.
