> MF is cheaper to acquire in film.

By "MF", I take it you mean medium format.

That a very excellent point that emphasizes how technology is often about trade-offs, not linear advancement. With film, it's far cheaper to increase the sensor size because the sensor is literally a consumable item. With digital, the sensor is an sophisticated electronic component that it's much harder and expensive to fabricate the larger you make them.

Yeah, basically for nostalgia and no other reason I prefer to shoot with full-frame sensors (like Nikon FX) rather than on the crop sensor (like DX). The larger-sensor digital bodies are considerably more expensive, even if they're years old and used.
