A: Hey, I heard you are into photography these days?
B: Yes indeed. Actually, since 3 years ago.
A: Awesome. What you are shooting with? Canon? Fuji?
B: A Sony. Full frame, mirrorless camera.
A: That’s a nice choice. I’m getting tired of carrying my DSLR. Guess I’m getting older.
B: Heheh, mirrorless is the way to go, I think.
A: …. so anyway, ever thought of shooting medium format?
B: What? Medium format you say? They are outrageously expensive, right?
B: Like what?
A: Shoot film, dude. Most of those old, film medium format gears are really affordable. Heck, they are cheaper than current flagship Canon/Nikon DSLRs. See, I bought this Rolleiflex at $150 at a garage sell.
B: Err, I thought film is already dead?
Hopefully this imaginary dialogue can give you a hint why most people don’t go medium format
