Used Hasselblad HC 1.7x Converter for the H Cameras

The Converter H 1.7x (3023717) increases the focal length of a lens by a factor of 1.7x. It features the same outstanding optical and mechanical quality as the elements in the Hasselblad H-lens series. All the glass-to-air surfaces have a multi-layer coating to reduce internal reflections and increase the efficiency of the optical system. The aperture reduction is -1.5 stops.

The Converter H 1.7x can only be used together with Hasselblad H lenses. Attempts to attach any other type of lens may cause damage.

Focusing
The Hasselblad Converter H1.7x does not change the readings on the distance scale on the lens, so the near and far limits of the focusing scale still apply. However, the depth-of-field scale no longer applies and should therefore be disregarded. Depth-of-field should be checked on the focusing screen using the depth-of-field button.

Light metering
Since the Converter H1.7x increases the focal length it also, according to the geometrical laws of optics, decreases the aperture of the total optical lens/converter system. The TTL metering system takes this into account automatically for general purposes. However, for critical applications alternative exposure settings should be made.

The Converter H1.7x is compatible with all H lenses except the following:
• HCD 4.8/24mm (3023024)
• HCD 4/28mm (3023028)
• HC 3.5/35mm (3023035)
• HC 4-5.5 / 35-90mm Zoom (3023590)
• HC 3.5-4.5 / 50-110mm Zoom (3023511)
