Wow, cool cam.
>> even smaller than an 1970′ SLR – maybe too small?

there are some odd things here, but maybe Nikon and Canon will follow Sony on the way to very compact, light-weight “Full”-Frame DSLRs.
(edit: please, not as small as the A7, thank you!)
They don’t even have to loose their mirror – I like a good optical viewfinder; and, without an electronic viewfinder, there is less battery consumption!

Started out doing photography at the age of 6 using an uncle's old 1940 kodak brownie box camera. At 15 years of age, I decided to buy my very own 1975 Praktica SLR camera. I now shoot with a Nikon D850. I do unpaid TFP and commercial paid work.
