This is a record of HASSELBLAD HCD 4.8/24 used with X2D,X1D and X1DII (which we believe is also applicable to 907X).

Impression
This is the 9th HC/HCD lens I have acquired.
I checked the lens on the X1DII and found that the firmware at the time of acquisition was 18.0.0 with 4000 shutter counts.
To use AF on the X1DII, the firmware was updated to 19.1.0.
I purchased this new lens with an orange dot on the lens barrel, a maximum lens shutter speed of 1/2000, X H Lens Adapter, and XH CONVERTER 0.8 to confirm that the firmware allows AF (auto focus) use.
The lens itself weighs 810g, 25mm smaller in length and 165g lighter than the HC 3.5/35mm, a wide angle lens in the same category (slightly shorter in length and lighter in weight than the HCD28mmm), making it very easy to carry and handle when shooting.
The 24mm is not so common in the used market, but this lens is very useful and reliable, providing a maximum focal length of about 16mm. The image quality is still more than adequate, although there is no doubt that some soft correction has been applied to the image.
The AF is one of the fastest among HC/HCD lenses, and once the photographer gets the hang of the AF, it is highly accurate, allowing the photographer to achieve the desired focus position.
The minimum focusing distance is 38cm throughout the entire range, which is not as close as the HCD28mm, and since the Extension Tube cannot be used, the close-up shooting ability is inferior to that of the HCD28mm (whether it is necessary to get that close is another question since it is a wide-angle lens).
The lens comes with a nice hood, but it is rarely worn in everyday use because the backlight resistance is sufficient without the hood.
Specification
The HCD 4.8/24 is a 24mm focal length wide angle lens for HASSELBLAD H series cameras.
Since this 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.
On X1D/X1DII, HC lenses can be used via X H Lens Adapter or XH CONVERTER 0.8.
- With the X H Lens Adapter, the focal length is 19.44 mm.
- With the XH CONVERTER 0.8, the focal length would be 15.55mm.
When the x0.8 converter is used, the image circle of the lens is not large enough and the edges are slightly vignetted, so Phocus software for developing photographic images automatically crops the edges slightly (to a focal length of about 18 mm). The full 15.55mm image before cropping can be viewed by clicking [Uncrop] in the Phocus image menu.

- The image circle of the lens does not cover medium format film (41.5 x 56mm).
- Converter 1.7x (x1.7 teleconverter) cannot be used.
- All expansion tubes (H13/H26/H52) cannot be used
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.
