Review

XENOMAX 50mm F3.5 is a standard lens officially released by Ms-optics that covers digital medium format sensors (44x33mm).
One of the lenses in the history series of MS-Optics (Miyazaki Optical), it is a Xenotar type lens that pursues high performance in terms of aberration and resolution. With a lens configuration of 5 elements in 4 groups, the aperture is 3.5, the shortest shooting distance is 0.5m, the lens length is 33mm, and the weight is 63g, making it very compact while still covering a digital medium format sensor.

With a simple lens barrel and a rotation angle of about 30 degrees from infinity to a minimum focusing distance of 0.5m, the camera can be expected to operate quickly. With EVF cameras, it may be difficult to adjust focus due to the small rotation angle.

When I used it with the HASSELBLAD X1DII/X2D, I found that when shooting with an image circle of 44mm*33mm sensor size, there was almost no disturbance in the periphery or lack of light. When taking pictures of blue skies, there were times when I felt there was a slight lack of light in the surrounding areas. For sensors smaller than 35mm full size, you can use only the most attractive part of the lens, making it a highly versatile lens.

When a raw image is developed straight, the tones are natural and the contrast is a little low.If you want to make an image more flashy, you can change the impression by increasing the contrast a little.
The lens name was called XENOR at the time of testing, but it was changed to XENOMAX at the time of release because the lens performance was No. 1 in Ms-optics.
