Revolution by Mirror-less camera

My lens resource has exceeded my own demand in number already, I have been interested too much in old lens modification hobby field, I was in such situation by modify Minolta SLR lens on Canon EOS mount several years ago before Mirror-less digital models are prevailing like now. So, tens of Rokkor lenses including zooms are at my hand, the condition means that only a mount adapter between Canon EOS and SONY E can play any Rokkor lenses as I desire. Remembering past, I had been a critical inconvenience with Canon Digital SLR camera body, darker scenery in darker OVF operation especially, I used manual focusing and manual iris controlling, I was in dark circumstance all the time.
Mirror-less body designing makes it possible to put various old Range -Finder camera lenses on the flange surface with flange back 18 mm depth, tens of old camera had been obliged to appear as donors by myself, most of them are standard focal length around 50 mm.
Now, I'm in a Paradise like circumstance with far lighter EVF scenery in addition the focusing point could be magnified with a single button action. As the focusing action is one of a sacred moment for me as if I pray to God, adjusting environmental focusing condition is the first requirement to start Photo Hobby again for me.
Now, I'm in a Paradise as a Dragonfly swimming there so freely.
I cannot be too much to appreciate to the engineers who had been contributing with bloody efforts in the researching and developing field.
