When I first started getting into old cameras I had no idea the size of some of the cameras I was interested in. I've decided to give some size comparisons so people in the same predicament can get an idea of the dimensions of a couple of these cameras.
Here's my Fed-2 with my Yashica Electro 35 GSN.
Both cameras with an assortment of stuff.
From left to right the stuff is: 35mm film canister, Darth Vader PEZ dispenser, roll of 120mm film, AA battery, and a C cell battery.
Same stuff different arrangement.
I hope this helps if someone out there is wondering about the size of these cameras.
