Same sensor as that “brick” the MX-1? Speaking of Pentax “bricks” which I own both the MX-1 and K-01, if I did it right here is a size comparison.

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.
