HASSELBLAD HC 4.5 / 300

This content is a record of the use of the HASSELBLAD HC 4.5 / 300 with the X2D, X1D and X1DII (which we believe is also applicable to the 907X).

This was the 8th HC/HCD lens I acquired.
Since I purchased the FUJINON brand lens at a reasonable price, I knew that I could not use AF (auto focus) with the X H Lens Adapter* and XH CONVERTER 0.8* at a shutter speed of 1/800.
The MF feel was good, and I was able to use the EVF’s focus magnification function to get the shot at the target position without any problem.
When using the X H Lens Adapter*, there were no problems even in backlit conditions, and the images output via Phocus showed undistorted image formation to the periphery and no peripheral fading, indicating that the performance is sufficient for use with the 44×33 sensor.
The lens itself weighs 2 kg, and the converter (175 g or 430 g) and camera (766 g) add up to over 3 kg, making it not a camera that can be easily carried around. If an x1.7 teleconverter is added, the total weight is 3.5 kg (+500 g), which is quite heavy.
Unfortunately, I had to return the lens due to frequent communication problems between the lens and the body, and ended up using it for only about two weeks. I would like to get it again if I have a chance, but I am hesitant to do so considering the frequency of use.
Later, I found an almost unused Orange Dot in a familiar camera shop and decided to buy it because it was very attractive in terms of price.

The HC 4.5/300 can be used with the x1.7 telecon in the H and X series.
We were able to test the HC 300mm with orange dot at Hasselblad Japan and confirmed that AF can be used with the telecon attached on the X1D/X1DII/X907. However, the AF focusing speed was very leisurely.
As of 2022.09.19, the latest X2D shows lens error 46 when using telecon H1.7.

Specificaton
The HC 4.5/300 is a telephoto, 300mm focal length lens for HASSELBLAD H-series cameras. Since it is an HC series lens, when used with the HxD medium format camera, it covers a sensor size of 40.2 x 53.7mm, at which time the focal length is approximately 197 mm.
The X1D/X1DII (907X) can use this lens via the X H Lens Adapter* or XH CONVERTER 0.8. When using the X H Lens Adapter, the focal length is approximately 240mm.
When using the XH CONVERTER 0.8*, the focal length is 192mm and the maximum aperture is 3.5.

Accessory compatibility

Converter H 1.7x (x1.7 teleconverter) can be used.
Extension-Tube-H (H13/H26/H52) can be used.
HTS 1,5 TILT AND SHIFT ADAPTER can not be used.
Image circle covers up to medium format film size.
IBIS works with X2D (firmware 1.0.0/1.0.5) and X H Lens Adapter.
~~As of 2022.09.22, the combination of X2D and Converter H 1.7x causes lens error 46.~~
With X2D firmware 1.0.5 released on 2022.12.15, the lens error does not occur when using Conveter H 1.7x.
IBIS does not work with Conveter H1.7x in X2D firmware 1.0.5 released on 2022.12.15.
IBIS does not work with XH CONVERTER 0.8 in X2D firmware 1.0.5 released on 2022.12.15.

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.

About FUJINON lens
HC lenses are available under the FUJI film brand (SUPER EBC FUJINON) and can be used with HASSELBLAD HC cameras, but the shutter unit is only available in the 1/800 era (this is not critical) and the lens firmware is old (this is critical). It is not possible to install the firmware (HC lens firmware 19.1) required to use AF (auto focus) with XCD mount cameras (X1D, X1DII, 907X).
Therefore, the AF function cannot be used with XCD mount cameras (X1D, X1DII, 907X) via a mount adapter (X H Lens Adapter, XH CONVERTER 0.8).

HASSELBLAD brand HC lenses are not covered by HASSELBLAD’s repair support and are no longer supported by FUJI FILM, so they cannot be repaired in case of failure.
FUJI brand HC lenses are sold at low prices, but care should be taken when purchasing them.

Since HC lenses are manufactured by FUJIFILM, the FUJIFILM GFX series, which has the same sensor size as the X1D, X1DII, and 907X, also offers a mount adapter (H MOUNT ADAPTER G). This one is exclusively for MF (manual focus), but it can use the lens shutter as well as the mechanical shutter on the camera side.
