Rainy days

Rainy days are lasting because linear rail zone is keep sitting on our main land these days. Utilizing free boring time, I made up two lenses for SONY Alpha 7, one is magnification lens for teardrop shooting and another is just a toy-like Lens Baby with no helicoid and ordinary iris adjusting system. The former one is consists of 75 mm/4.5 Fujinon-ES for enlarging and developing purpose. Former fabricated barrel and 82 mm extension tube reproduce 2.3 to 3.3 multiplies.
Latter one required to prepare adapter ring to fill the clearance because it had been done for DSLR A mount with mirror box distance. Both an E-mount body cap and an originally boxed A-mount lens rear cap could play good for the purpose to compensate 22.5 mm length though they lack 2 mm distance, it worked well for actual focusing procedure, even in that condition it focusing at 2 m point. With pushing and pulling actions it performs as a normal 50 mm standard lens on Full-size format. Newly fabricated 2 lenses would contribute to make myself satisfy for the time being.
