Context

Pentax positioned the 645NII in 2001 as a professional-grade medium format SLR, competing with systems like the Contax 645. It was part of the broader Pentax 645 system and built on its predecessor with improved handling and functionality.

Market

Collectors still want the 645NII. Serviced bodies are listed at $1,100, and complete kits on eBay have reached $1,299.99. The earlier 645N had reported battery issues, but users say the 645NII runs reliably on standard AA batteries. A service parts list is available for $8.99, so repair support is limited but exists.
