Impression
This is the second XCD lens I introduced.
It is compact enough for a medium format wide-angle lens, and the AF is in focus with reasonable accuracy.
It is very good that an angle of view equivalent to 17mm is achieved at this size. The brightness is also sufficient at F4, and when Phocus is used, various corrections are perfect to obtain a wide-angle image without distortion.
I sold the HC24mm + XH-Converter 0.8 because I had already acquired it, but I think it is an essential lens when operating only with XCD.

Specification
It is the widest angle lens in the X-mount lens group used in the X1D/X1DII/X907.
Priced at around 550,000 yen new, this lens has the same 1/2000 lens shutter as the other XCD lenses.
