Overview / 概要
Why Pentax 645 matters.
The 645 format was a practical bridge for photographers who wanted more negative area without fully changing working habits.
Design & context
The integrated grip and motor drive make this a working camera rather than a slow studio object.
Buying today
Check film transport, battery contacts, and the shutter; the body is substantial but still manageable in the field.
