The Mamiya 645 1000s (1976) is an early-period 6×4.5 medium-format SLR. The "1000s" indicates the **1/1000s top shutter speed** — a step up from the original 1973 Mamiya 645's 1/500s. The body is **non-modular** — the film insert slides into the body but doesn't swap as a complete back like the later 645 Super / Pro. Electronic focal-plane shutter, TTL CdS metering through the optional prism finder, manual exposure only.

The Mamiya 645 line started 1973 with the original M645 (1/500s top shutter). The 1000s (1976) added the faster shutter and refined controls. Replaced 1985 by the Mamiya 645 Super (modular back system). Production was substantial — Mamiya 645 was the high-volume entry-level Japanese medium-format SLR through the 70s/80s.
The 1000s is the cheapest entry into Mamiya 645 medium format. Used at $250–600 with one lens — half the price of a 645 Pro. Image quality is identical (same Mamiya-Sekor lens system); the trade-off is the non-modular film system (you can't swap backs mid-roll between 120 and 220) and the older electronics (battery contacts can corrode more easily).
For photographers entering medium format on the tightest budget, the 1000s + 80mm f/2.8 N at $400 is one of the cheapest "pro-quality" medium-format kits.
Mamiya-Sekor C lenses (and N variants for later bodies; they all mount on 1000s): 80/2.8 N (kit), 45/2.8, 55/2.8, 110/2.8, 150/3.5, 210/4. Metered prism finder, plain prism finder, waist-level finder (default). Power Drive Grip (auto-wind, optional).
