Many styles of photography involve stages of: Focus, Re-compose, and Shoot. These stages are naturally supported by all Hasselblad cameras, with the auto-focus system of the HC/HCD lenses working at outstanding performance.

Compared to a 35mm DSLR the Hasselblad medium format DSLR works with a shallower depth-of-field. Here our new True Focus functionality secures accurate composing at close distance with shallow depth-of-field.

In the H4D cameras we use modern yaw rate sensor technology to measure angular velocity in an innovative way. The result is the new Absolute Position Lock (APL) processor, which forms the foundation of our True Focus. The APL processor accurately logs camera movement during any re-composing, then uses these exact measurements to calculate the necessary focus adjustment, and issues the proper commands to the lens’s focus motor so it can compensate.

This technology refines the Hasselblad H4D auto-focus to an entirely new level, correcting for the vertical and horizontal focus-shift that results from the rotation of the camera around an axis close to camera. In simple terms, True Focus allows the photographer to concentrate on their composition, to focus on their creativity, while True Focus takes care of the other, more mechanical aspects.

True Focus modes of operation include:

Mode 1 (camera in AF-S which is default when loading “default” profile)
Focus, using the True Focus button
- beep confirms focus locked
- True Focus icon in viewfinder turns “hot”
Re-compose
Shoot (leaving the camera in AF-S)


Mode 2 (camera in AF-T)
Focus, using the True Focus button
- beep confirms focus locked
- True Focus button in viewfinder turns “hot”
Re-compose
Shoot,
Shoot again, and again … (leaving the camera in AF-T)
