impression
This was the third HC/HCD lens that I introduced, and although it was used, it was in almost new condition with three shutter cycles.
I purchased this new lens with orange dot on the lens barrel, a maximum lens shutter speed of 1/2000, X H Lens Adapter, and XH CONVERTER 0.8 to make sure that the firmware was compatible with AF (auto focus).
The weight of the lens alone is 1.4kg, but the lens is well-balanced when mounted on the camera, so I don’t feel bothered even if I use it for a long time.
With the X H Lens Adapter or the XH Converter 0.8, the lens covers the range from 24mm to 72mm, making it a lens that I use frequently.

The AF is one of the faster focusing speeds among HC/HCD lenses, and once you get the hang of the AF, the focusing accuracy is high and you can get the focus position as you want.
The minimum focusing distance is 65cm throughout the entire range, giving the impression of being able to get closer to the subject at focal lengths of 50mm or longer.
The lens comes with an impressive hood, but it is rarely worn in everyday use because the backlight resistance is sufficient without the hood. This backlight resistance and the 1/2000 lens shutter speed make it useful for outdoor photography.
The drawback is that it is very conspicuous depending on where you take it because of its large size.

Specification
The HCD 4.0-5.6/35-90 is a zoom lens that covers a focal length range of 35mm to 90mm for HASSELBLAD H series cameras, with inner focus and inner zoom, and the lens length does not change with focal length or focus position.
Since it is a HCD lens series, it is optimized for 48 x 36 mm sensor size. The lens image circle is not large enough for the larger 53.7 x 40.2 mm sensor, resulting in vignetting on the periphery.
The lens with the orange dot has a lens shutter with a maximum speed of 1/2000, while the unmarked lens has a lens shutter with a speed of 1/800.
The X1D/X1DII can use HC lenses via the X H Lens Adapter or the XH Converter 0.8.

X H Lens Adapter, the focal length is equivalent to 28mm to 72mm (0.8x).
XH CONVERTER 0.8, the focal length is equivalent to 24mm to 58mm (0.64x).

When using the x0.8 converter, the periphery of the image is slightly cropped due to the insufficient image circle of the lens, so the periphery of the image is automatically cropped in the Phocus software.
If you want to see the entire image before cropping, execute Uncrop from the Phocus Image menu.

Accessory Compatibility

Extension-Tube-H (H13/H26/H52) can be used (not mentioned in the data sheet of the extension tube, but can be used on the X1D/X1DII).
Converter 1.7x (x1.7 teleconverter) cannot be used.
HTS 1.5 TILT AND SHIFT ADAPTER cannot be used.
Image circle does not cover medium format film (41.5 x 56mm).

AF support
For the orange dot lens, AF is available on the X1D/X1DII (907X), but it only works with the latest firmware 19.1.0, so if you have 18.0.0, you need to update the firmware. In fact, when I purchased the camera, the firmware was 18.0.0, so the AF did not work when I tried it. After purchasing the camera, I updated the firmware and was able to get the AF to work.
If you have firmware 17.0.0 or earlier, you cannot update the firmware because the firmware area is not enough for 19.1.0.
The AF speed when used with the X1D/X1DII (and probably the same with the 907X) is not quite as fast as that of a professional SLR, but if you choose a high contrast area, the camera will focus without hesitation, which is easier to use than fast but confusing AF, and is sufficient for my needs.
