Review
1．Usage
The Dagonar 40mm is the second lens in the MS-Optics (Miyazaki Optical) History Series, and is a lens that pays homage to the DAGOR.
The main specifications are as follows, and detailed specifications are listed in the table.
- Lens construction: 2 groups, 6 elements, symmetrical type
- Minimum focusing distance: 0.3m
- Rangemeter coupling for M-type Leica: 0.85m
- Aperture value: F6.3-16
- Lens length: 22mm
- Maximum lens diameter: 50mm
- Weight: 50g
The “H” in the lens name “H-DAGONAR” stands for History, and means that it is the second lens in the MS-Optics History Series.
The DAGOR was a lens that was installed in cameras manufactured by the German camera manufacturer Goertz.
2．Overview
Compared to modern, heavy, and large lenses, the DAGOR is overwhelmingly compact.
Still, shooting operations such as aperture and focus can be performed quite normally. The focus ring is moderately heavy and rotates about 120 degrees, making it easy to make subtle adjustments. There is no aperture clip stop.
The Dagonal 40mm is a sister lens to the Proto 40mm, the first in the History series, and compared to the two, the Dagonal is slightly longer and heavier because it uses two more lenses.
Both the DAGOR and Proto were unpopular and left unsold when released due to their subtle focal length of 40mm and dark maximum aperture, but due to the small number of units manufactured, the number of them on the used market has decreased, and as of 2025, they have returned to a reasonable price.
Comparing the two, the impression is that when comparing images taken of the exact same subject at the same distance, the DAGOR 40mm appears to have slightly higher resolution.
When the camera was fixed to a tripod and only the lens was changed to shoot the same subject, it was found that the shooting range of the DAGOR was slightly narrower. This is thought to be due to manufacturing errors or subtle differences in focal length.
If you were to consider which to choose when taking the two out with you, if you wanted a shooting system that was even slightly more compact, you would go for the Proto, and if you wanted slightly higher performance, you would go for the DAGOR.
When used with the HASSELBLAD X2D via an X-M mount adapter, the focal length is equivalent to 32mm in 35mm format. For the 44 x 33mm sensor used in medium-format digital cameras, the shooting results showed only slightly noticeable vignetting, the peripheral resolution was also fully within the practical range, and it was confirmed that the image circle of the lens is wide.
The X2D does not have a mechanical shutter and shoots with a sensor shutter, but with a sensor shutter, rolling distortion can occur when shooting moving subjects, so the Fujifilm GFX series, which has a mechanical shutter, is more practical to use.
3．Summary
To conclude, the H-DAGONAR 40mm F6.3 is a sister lens to the H-PROT, released at the same time.
The H-DAGONAR has two more lens elements than the H-PROT, and its aberration correction is slightly better than that of the H-PROT.
Since the maximum aperture is slow, it is suitable for use with digital cameras that can use high ISO sensitivities.
