Please note that this lens does not have any identification marks on its body. It only says '25mm F1.8 HD VIII' on its case and only one single 'VISIONLENS' on its box. This lens is often referred to as 'FUJIAN 25/1.8' by analogy with other similar solutions, for example, FUJIAN CHINA TV LENS GDS-35 f=35mm 1:1.7. In this review, for convenience, I will call it exactly the same - FUJIAN 25 / 1.8. There are modifications with an inscription near the front lens 'mini lens'.

This lens has a C-MOUNT mount (thread) and can be easily installed on any modern mirrorless camera using a simple and cheap adapter. In the review, I used a FUJIAN 25 / 1.8 lens with an adapter C-mount -> Sony E/NEX (black color, but there are silvery).

It's important: FUJIAN 25/1.8 is available in two body colors: black and silver. This review shows the silver version. For some reason, it didn't come with the lens silver, the black Adapter C-mount -> Sony E/NEX.

In short

Fujian 25 / 1.8 - a modern fast manual focus lens, uses a C-MOUNT mount, which makes it easy to adapt on any modern mirrorless camera. Covers APS-C sensor. One of the cheapest such fixes for cameras with an APS-C sensor and a maximum aperture of F / 1.8.

25 mm is a very convenient focal length that allows you to use the Fujian 25 / 1.8 as a standard (standard) lens for a huge number of different photo tasks.

Fujian 25/1.8 is interesting for its very low price and maximum aperture ratio of 1:1.8. It has some optical flaws, but in general it fully justifies its cost.

Fujian 25 / 1.8 - in general, is the best solution among other Fujian lenses: 25/1.4, 25/1.8 (from this review), 35/1.6, 35/1.7, 50/1.4 when used on cameras with an APS-C sensor. First of all, with Fujian 25 / 1.8, you can achieve normal sharpness in the corners and edges of the image.

UPDATE: list of all FUJIAN lenses here.

Many amateur photographers want a fast fix, especially in addition to their full-time / 'whale' lens. Aperture F / 1.8 two or more steps wider aperture F / 4, which is used in 'dark' whale lenses at 25 mm focal length. In numerical terms, this means that the Fujian 25 / 1.8 is approximately 5 times brighterthan, for example, regular Sony 18-55mm f / 3.5-5.6 OSS or Sony 16-50mm f / 3.5-5.6 PZ OSSwhich use a maximum relative aperture of only 25: 1 and 4: 1 at 4.5 mm of focal length. The calculation of the difference in the relative aperture (count the aperture) is performed elementarily: (4 * 4) / (1.8 * 1.8) = 4.94, which is rounded to the value '5'.

It's important: F/1.8 aperture here is 'true', with light transmission around T/2. I compared Fujian 25 / 1.8 with a lens Sigma 30mm 1: 1.4 DC DN C (Contemporary). Lately I've been careful about the maximum relative aperture, there have already been many cases of cheating with the indication of the real maximum aperture by some Chinese manufacturers: 7Artisans 35 / 0.95, 7Artisans 50 / 1.05, Pergear 35 / 1.6 etc.

Assembly

The lens came to the review completely new, in a sealed box. The box contains the lens itself with front and rear caps and a macro ring with a C-NEX adapter.

In general, the lens is assembled well, although it is noticeable that it is a little rough. Fujian 25/1.8 has metal mount for bayonet, and the lens case itself is completely made of metal.

The front lens cap is plastic, without latches, just fit snugly on the outside of the lens.

The weight of the lens is just under 100 grams. In the hands of the lens feels like a nice thing.

The filter diameter is only 37 mm.

The diaphragm consists of 6 petals and forms a hole in the shape of a regular hexagon. The diaphragm can only be controlled manually using a special ring. Aperture ring rotates smoothly no clicks and fixed values, you can set any intermediate value in the range of F / 1.8-F / 16, which is very useful during movie shooting.

The aperture control ring rotates rather tightly, it will be difficult to accidentally knock down the set value.

It's important: when mounted on the camera, the focusing distance scale and the aperture scale are located on the bottom of the camera (most likely a problem due to the adapter).

Focusing

The focus ring is metal, ribbed, comfortable. The ring spins on 90 degrees. Focusing is smooth.

During focusing, the trunk of the lens runs forward but does not spin. During focusing, the entire lens block moves, but in the middle of the lens barrel.

On the ring there is a scale with a focusing distance, but only in meters. The minimum focusing distance is 20 centimeters and the maximum zoom ratio is approximately 1:8. The lens comes with a special macro ring, which allows you to achieve a magnification of 1:2. The macro ring is screwed onto the mounting thread of the lens and the 'C-MOUNT -> desired system' adapter is already installed on it.

Fujian 25/1.8 has a slight 'Focus Breathing' effect. During focusing towards the MDF, the viewing angle decreases.

Hard stop (hard infinity mechanical stop) for fast and accurate focusing under any operating temperature conditions, the lens does not have. With adapter C-mount -> Sony E/NEX (included) there is a small flight of infinity at the extreme position of the focus ring.

Focus peaking with Fujian 25/1.8 and cameras Sony a3500 and a Sony NEX-6 works well at F / 1.8.

Image quality

On covered apertures Fujian 25/1.8 easily handles 20 megapixels APS-C sensor Sony a3500 and 16 MP Sony NEX-6. In the center of the frame, Fujian 25 / 1.8 is already sharp at F / 1.8.

Sharpness

  1. F / 1.8 lens has quite tolerable resolution in the center of the frame
  2. with aperture down to f/2.8 resolution becomes excellent
  3. there is a slight drop in sharpness towards the edges and corners of the frame, but even in the far corners of the frame at f / 1.8 the lens holds up well
  4. on covered diaphragms, corners and edges are in perfect order
  5. palpable coma

Distortion

  1. there is a small barrel-shaped distortion
  2. distortion is unified, easy to edit in the editor

Vignetting

  1. weak vignetting at f/1.8 (which is odd considering it's a CCTV lens originally designed for use with smaller sensors)
  2. vignetting decreases with focus towards MDF. Most noticeable when focusing on infinity
  3. vignetting almost completely disappears at F / 2.8
  4. vignetting easily fixable in the editor

Aberration

  1. there is a noticeable amount of chromatic aberration
  2. there is a noticeable frigging (the color of contrasting elements in the out-of-focus area is purple or green)

Rest

  1. on covered apertures it is difficult to achieve a beautiful effect of a 12-ray star
  2. from bright light sources you can get glare and drop in contrast

Important: at the time of writing this review, there was no Fujian 25/1.8 profile for popular RAW converters. You can create a profile yourself or wait for its release.
