In short
7Artisans 25mm 1: 0.95 - modern manual (manual focus only) particularly fast fixed focal length lens for mirrorless cameras with APS-C or Micro 4/3 sensor. First of all, 7Artisans 25mm 1:0.95 is aimed at creative shooting, video shooting. 7Artisans 25mm 1:0.95 is easy to use and can act as a standard prime lens for every day.
7Artisans 25mm 1:0.95 is interesting for its very high quality assembly, a large number of aperture blades and a maximum aperture ratio of 1:0.95.
This lens belongs to the 7Artisans line Firefly ('Firefly', this name is most likely a reference to the high aperture of the lens). This series includes only three solutions: 25/0.95, 35/0.95 и 50/0.95. 7Artisans claims that the 7Artisans 25mm 1:0.95 optical design uses three low dispersion elements from HOYA.
Among the disadvantages are the standard optical problems inherent in such inexpensive high-aperture optics, first of all, strong chromatic aberration and very low resolution in the corners and edges of the frame at medium and short focusing distances.
Aperture F / 0.95 more than four steps wider aperture F / 4, which is used in some 'dark' standard ('whale') lenses. Each step gives a twofold increase in aperture ratio: 1 -> 1.4 -> 2 -> 2.8 -> 4. In numerical terms, this means that 7Artisans 25mm 1: 0.95 should be 18 times lighterthan stock lens Sony 16-50mm f / 3.5-5.6 PZ OSS, which at a 25 mm focal length can use a maximum aperture of only 1: 4. The calculation in the difference in relative apertures (count the luminosity) is simple: (4 * 4) / (0.95 * 0.95) = 17.73.
Separately, it should be noted that the relative aperture of 1:0.95 is 'honest' and gives light transmission in the region of T / 1.0-T / 1.2 (that is, the real aperture lens, expressed in T-stops, corresponds well to the declared maximum aperture of F / 0.95).

The creative potential of such a lens is difficult to overestimate. Amateur photographers often use it as a regular prime, sometimes as a portrait lens. Many people just want a fast prime in addition to their 'whale' lens. Of the autofocus solutions, 7Artisans 25mm 1:0.95 is closest to the Olympus M.Zuiko Digital 25mm 1:1.2 PRO Micro 4/3 systems. The difference between 1:0.95 and 1:1.2 is about 60%. Most likely F / 0.95 instead of F / 1 is more used for a psychological / marketing effect.
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 small instruction manual. There are very large and soft foam holders in the middle of the box. The design of the box is stylish and beautiful. Initially, the box is girded with an additional beautiful cardboard wrapper, which serves as a seal.
In general, the lens very well assembled... 7Artisans 25mm 1: 0.95 has metal mount for bayonet, and the lens case itself is completely made of metal, anodized aluminum is used.
Important: lens mount also painted black (dark brown)which makes the 7Artisans 25mm 1: 0.95 design complete and pleasant enough. Usually these lenses have a metal mount without color. True, the red color of the marks is shifted closer to pink, which is a little strange and unusual. A stricter red would look much better.
Part of marks and inscriptions on lenses engraved.
The front lens cap is metal, without latches, just fits snugly against the body frame. There is a special fabric seal on the inside of the lid. The cover is fixed tightly. Removing and installing the cover is pleasant.
The weight of the 7Artisans 25mm 1: 0.95 lens itself is almost 600 grams. In the hands, the lens feels like a solid thing.
The diameter of the filters is 52 mm. By itself, 7Artisans 25mm 1:0.95 is quite large.
The diaphragm consists of 13 (thirteen!) petals and forms a round hole at any values, while in the photographs in the out-of-focus area, rather round discs of confusion are obtained at any aperture values. Strange, but the cheaper model 7Artisans 55 / 1.4 14 petals are used. The diaphragm can only be controlled manually using a special ring. The diaphragm ring rotates smoothly, no clicks and fixed values, you can set any intermediate value in the range of F / 0.95-F / 16, which is very useful during movie shooting.
It's important: Unlike other lenses, where the aperture ring clicks and the transition between any pairs of f-numbers has the same pitch, the pitch between pairs of 7Artisans 25mm 1: 0.95 numbers is always different. It shrinks from f / 0.95 to f / 16. This makes it difficult to conveniently and quickly set values from F / 1.4 to F / 16. And for the marks F / 5.6 and F / 11 there was no place on the scale at all (instead of the numbers F / 5.6 and F / 11, dots are used).
It's important: aperture control ring is located from the front of the lens, behind the focus ring. This arrangement of the aperture ring is quite convenient. On other lenses, such as 7Artisans 35 / 1.2, the aperture control ring is close to the mount and it is not always convenient to rotate.
What is the actual aperture ratio (T-stop) at f / 0.95?
The light transmission of the lens is expressed 'T' steps. It is this value that is considered to be the 'real' indicator of lens aperture. Typically, T-stops (T-stops) are linked to aperture stops (F-stops). Quality lenses have pretty close numbers around 'T' and 'F'. For example, a high-quality lens with a maximum aperture ratio of 1:1.4 (aperture number F/1.4) has a light transmission of T/1.5-T/1.6. Lenses with F / 2.0 at the level of T / 2.1-T / 2.2, F / 2.8 at the level of F / 2.9-F / 3.0 and so on and so forth. The light transmission of 7Artisans 25mm 1:0.95 at F/0.95 is in the region of T/1.0-1.2, which is very, very good. It is safe to say that the relative aperture of 1: 0.95 for this lens is honest (unlike its brother 7Artisans 35 / 0.95).
True, the exact deviation from 1:0.95 (as in the case of honest 7Artisans 50 / 0.95) this time I could not find out, because at hand Anna Anuttara there were only reference lenses Meike 7.5/2.8 FISH-EYE и Sony E 3.5-5.6 / 18-55 OSS.
Focusing
The focus ring is wide enough, metal, ribbed. The ring rotates approximately 90 degrees (about 1/4 of a full turn). The focus ring is poorly stretched in the range from 2 meters to infinity. Focusing is smooth and pleasant. The focus ring has a 'oily' stroke. In general, I would like an even stiffer stroke, since it is very easy to knock down the set focusing distance.
During focusing, the trunk of the lens runs forward but does not spin. Together with the trunk, the diaphragm control ring also leaves. Focusing is performed by moving the entire lens block (the rear lens moves). Most likely, the lens does not have an image quality correction system at close focusing distances.
On the ring there is a scale with a focusing distance in meters and feet and a depth of field scale. The minimum focusing distance is 25 centimeters and the maximum magnification ratio is approximately 1:8 (approx.).
7Artisans 25mm 1: 0.95 has weak 'Focus Breathing' effect (changing the angle of view during focusing). When focusing towards the MDF, the angle of view decreases slightly. I was pleasantly surprised by the weak 'Focus Breathing' effect.
Focus Shift (shift focus, change in focusing distance due to aperture) is missing.
Hard stop (hard infinity mechanical stop) for fast and accurate infinity aiming under all operating temperatures no. The sample from the review has a small infinity flight in the extreme position of the focusing ring.
Focus picking with Sony NEX F3 at F / 0.95 it works well even if low peaking is enabled.
Image quality
7Artisans 25mm 1:0.95 has obvious serious problems. Image quality is highly dependent on focusing distance and part of the image. In general, the lens produces the best result at long focusing distances. The smaller the focusing distance, the more noticeable the resolution drops in the corners and edges of the image. At F / 0.95, the lens does not produce high optical performance, but still surprises with tolerable sharpness in the center of the frame.
Sharpness
- at close focusing distances at F / 0.95 the corners of the frame are just awful, the corners of the frame return to normal only after aperture F / 8, but even at F / 16 it cannot be argued that the corners of the frame meet the high requirements for resolution
- at long focusing distances, the frame angles fall back to normal at F / 4 and show high resolution in the F / 8 region
- at F / 0.95 the center of the frame is weak, primarily due to spherical aberrations
- after F / 2, good resolution is achieved in the center of the frame, after F / 4 - excellent
- the upper left corner of the image is always worse in resolution than the upper right corner (when the frame is horizontally oriented)
- there is a severe coma
Distortion
- there is a complex barrel-shaped distortion
- edges and the corners of the frame are strongly pulled out (complex part of distortion)
- distortion is difficult to fix in the editor
Vignette
- there is a significant vignetting at F/0.95 (example)
- vignetting decreases with focus towards MDF. Most noticeable when focusing on infinity
- vignetting almost completely disappears at values after F / 4
- vignetting easily fixable in the editor
Aberration
- strong chromatic aberration throughout the field of the frame (example)
- a noticeable amount of spherical aberrations at F / 0.95
- chromatic aberration decrease significantly after closing the aperture to f / 2.8
- the strongest chromatic aberration traceable at the corners and edges of the image
- strong milling
Rest
- from bright light sources you can get a lot of glare. But in the general case, there are no special problems with back and side light, in order to get a large amount of glare - you need to try
- The discs of blur towards the edges and corners of the frame turn into pronounced 'lemons', they are strongly flattened, and the bokeh takes on a twisted character. In general, bokeh is not the most pleasant
Important: at the time of writing this review, there was no 7Artisans 25mm 1: 0.95 profile for popular RAW converters. You can create a profile yourself or wait for its release.
It's important: electronic front curtain shutter of some cameras can severely spoil bokeh at wide apertures and shutter speeds faster than 1/1000 second, the causes of this problem are described here. The lens is not to blame, it is purely a feature of the shutter of some cameras.
It's important: for 7Artisans 220mm 1:0.95, for example, paired with Sony a3500 when the aperture is closed, the color rendition changes significantly. At full aperture, the image is tinted slightly pink / pinkish purple. Auto white balance sometimes copes well with this feature, but with manual installation white balance this effect is significant. Sometimes automatic white balance is greatly mistaken. With the aperture closed to F / 1.4-F / 2.0, color reproduction returns to normal. Perhaps on some other cameras the lens will behave in a similar way. Once again, this behavior is It's a problem with some cameras.. I assume that this is a parasitic reflection of the rays coming from the camera sensor itself by the rear lens of the lens back to the sensor (for example, the matrix and the camera's external filter Sony a3500 visually shimmer with pink-violet and green hues), perhaps the reason is something else. This effect is being vigorously discussed on the social networks of Radozhiva using the example of a lens 7Artisans 50 / 0.95: here (Facebook) и here (Youtube)At the same time, for example, Sony NEX F3 there is no such problem.

Video review
UPDATED
This video shot on 7Artisans 25mm 1:0.95 and Sony a3500 (ISO 100, F/0.95, 1/100).
Results
7Artisans 25mm 1:0.95 is a very interesting creative tool. Record big aperture. At F / 0.95 it blurs the foreground and background very much. Image quality is highly dependent on focusing distance and frame area. The lens has many nuances with image quality. Working with F / 0.95 is not so difficult. Unfortunately, 7Artisans 25mm 1:0.95 is very weak in the far corners of the frame at close and medium focusing distances. It should be noted that there is no full-fledged autofocus analogue for 7Artisans 25mm 1: 0.95. Because of its 'complex nature' the 7Artisans 25mm 1:0.95 is a truly rare and unique creative instrument. But for most photo tasks, less aperture, but autofocus Viltrox 23 / 1.4 AF (bayonets X, E, Ef-m, Z) would be preferable.
10 main advantages
- very high aperture (T-steps around T/1.0-1.2)
- good build quality: the lens body is completely made of metal, the optical system uses low-dispersion elements from HOYA
- very smooth focus ring, pleasant to use
- weak Focus Breathing effect
- there is a depth of field scale and focusing distances
- 13 diaphragm blades that always give a rounded hole
- the aperture ring rotates smoothly, without intermediate values (important for movie shooting)
- the aperture control ring is located in front of the lens, which is very convenient
- at f / 0.95 is not as bad as you might expect, especially at medium to long focusing distances
- peculiar bokeh
10 main disadvantages
- no CPU pins to form the correct EXIF
- a threaded (non-bayonet) hood should be used; no hood is included in the scope of delivery
- small non-linear step at the aperture control ring between F / 2-F / 16
- focus ring rotates only a quarter of a full turn
- there is no lens profile for popular RAW converters, the lens is not 'hardwired' into modern cameras
- mediocre resolution at f / 0.95 in the center of the frame
- critically weak corners and edges of the image in the F / 0.95-F / 8 range at close and medium focusing distances
- strong chromatic aberration
- strong glare / ghosting possible in strong back and side light
- complex distortion

Damn, from the picture I thought the partisans riveted the TV set)
Does anyone have examples of full-length and half-length portraits of adults in the open? This is the most intersting thing.
Who cares, but I like the picture and the blur on the open. It looks like a monocle.
