HASSELBLAD Converter H 1.7x

Review and Photo example of the Converter H 1.7X.

Table of Contents



Converter H 1.7X makes the maximum aperture of attachable H series lenses 1.5 stops darker, but increases the focal length by 1.7 times. The shortest shooting distance of the original lens can be utilized as is, without compromising the lens and its optical performance. When I compared images taken with several lenses with and without teleconversion, there was no clear impression that the image quality deteriorated.

Lenses that can use a teleconverter are HC lenses with a focal length of 50mm or more; HCD lenses, HC35mm and HC50-100mm, cannot be physically attached.
Can be used with X1D, X1DII, 907X, and X2D via X H Lens Adapter and XH CONVERTER 0.8.

In the case of the HC300mm lens, which is most often used in combination with a teleconverter, the lens (2120g) + teleconverter (465g) + XH-Adapter (180g) + X2D (800g) weighs approximately 3.5kg, making it a fairly heavy system.

AF support when using teleconverter

AF works with X1D/X1DII/X907 when the lens is equipped with extended firmware.
I tested with the HC 3.5/50(II) to see if the teleconverter would work when using the XH CONVERTER 0.8* through it, and it worked fine.
Since I felt there was little point in using the teleconverter for 1.7x and the wide converter for 0.8x, I didn’t do any more in-depth testing than to confirm operation.
Other limitations are the same as when the teleconverter is not used.

FUJINON lens when using teleconverter

When using this teleconverter with the X1D/X1DII/907X, there are no limitations except for the fact that AF cannot be used when using it via the X H Lens Adapter.
When using it via XH CONVERTER 0.8, the problem of not being able to use HC Macro 120mm of older model (lens firmware before 17.0.0.) remains.
