This is not a buying guide to the best medium format cameras at all levels. It does not include high-end modular systems from Hasselblad and Phase One. It covers a new generation of much more affordable medium format cameras designed for portability and handheld use, and higher-quality and perhaps more desirable alternatives to full frame cameras.
Hasselblad
Hasselblad is one of the best known and longest running names in professional photography, having built its reputation on its modular medium format cameras and now specializing in digital versions which boast extended backwards compatibility. Hasselblad is now owned by Chinese drone maker DJI.
