The Hasselblad 500CM is a compact, modular 6×6 medium format system, while the Mamiya RB67 is a larger, heavier camera that shoots a bigger rectangular frame. Choose the Hasselblad if you value portability and a square frame, and choose the RB67 if you want a bigger negative and a rotating back for easy portrait or landscape framing. Confirm exact details with a trusted dealer or maker documentation.

What Each Camera Is For
The Hasselblad 500CM is a classic waist-level single lens reflex camera with interchangeable lenses, film backs and viewfinders. Its square frame suits a certain style of composition, and its size makes it more practical to carry for travel and street work than most medium format bodies.
The Mamiya RB67 is a studio-friendly camera known for its bellows focusing, large negative and rotating back. It is bulkier, but it is popular for portraits and studio sessions where weight matters less.

How to Choose
- Think about carrying. If you walk with the camera all day, the lighter Hasselblad is easier.
- Decide on frame shape. Square suits those who crop later, while 6×7 is closer to a standard print ratio.
- Consider tripod use. The RB67 is happiest on a stand, where its size is an advantage.
- Check lens availability and servicing for either system in your area.
- Inspect any used camera: shutter speeds, light seals, film back function and lens haze.
Who Should Choose Which
- Choose the Hasselblad 500CM for travel, walking around, and a square-format look.
- Choose the Mamiya RB67 for studio portraits, tripod work and a larger negative.
- Choose either one if you simply want to learn medium format film, since both are mature, well-documented systems.
FAQ
Which is easier to use for a first medium format camera?
Both involve manual focus and a waist-level view that appears reversed left to right. The RB67 feels slower because of its size, while the Hasselblad is lighter but needs careful handling of its modular parts.
Are used examples reliable?
Both are old mechanical cameras, so condition varies. Buy from a seller who shows the camera working, and plan for a possible service.
The Short Version
The Hasselblad 500CM is the compact, square-format option, and the Mamiya RB67 is the larger, studio-style option with a bigger frame. Choose by how you will carry and use the camera, and confirm condition and details with a trusted source before buying.
