In short

7Artisans 55 / 1.4 is a modern manual fast fixed lens for mirrorless cameras with an APS-C sensor or less (for crop). One of the most inexpensive such fixes for cameras with APS-C sensor. The potential of such a fast aperture lens (a lens with a focal length of about 50 mm) is very large.

7Artisans 55 / 1.4 is interesting for its low price, high-quality assembly, good bokeh, a large number of aperture blades and a maximum relative aperture of 1: 1.4.

Among the shortcomings are standard optical problems inherent in such low-cost aperture optics, first of all, poor resolution at F / 1.4.

Price

The creative potential of such a fifty dollars is difficult to overestimate. It is suitable for a wide range of photo tasks. Photo enthusiasts often use it as a portrait lens. Many just want a fast fix, in addition to their whale lens. So, f / 1.4 aperture four steps wider f / 5.6 aperture, which is used on long-end 'dark' whale lenses. Each step gives a twofold increase in aperture: 1.4 -> 2 -> 2.8 -> 4 -> 5.6. In numerical terms, this means that 7Artisans 55 / 1.4 16 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 50: 55 at 1-5.6 mm of focal length. The calculation of the difference in the relative aperture (count the aperture) is performed elementarily: (5.6 * 5.6) / (1.4 * 1.4) = 16.

Assembly

It's important: 7Artisans 55 / 1.4 is available in black and silver. The review shows a lens with a black body color. The silver color of the case can be useful to those users who have silver or white / gray cameras.

The lens came to the review new, in a sealed box. The box contains the lens itself with front and rear covers, a small instruction and a pass on passing quality control. In the middle of the box there are very large and soft foam holders.

In general, the lens very well assembled. 7Artisans 55 / 1.4 has bayonet mount metal and the lens case itself is completely made of metal, anodized aluminum is used.

Important: lens mount also painted blackwhich makes the design of 7Artisans 55 / 1.4 complete and pleasant enough. Typically, such lenses have a metal mount without painting.

The weight of the 7Artisans 55 / 1.4 lens is a little over 250 grams. In the hands of the lens feels like a good thing.

The diameter of the filters is 49 mm. 7Artisans does not try to optimize its lenses for one or two filter diameters and almost every lens uses its own size.

By itself, the 7Artisans 55 / 1.4 is quite compact, well suited for small Sony cameras with an APS-C sensor.

The diaphragm consists of 14 (fourteen!) of petals and forms a round hole at any values, while in the photos in the blur zone, rather round discs of blur are obtained. 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 / 1.4-F / 16, which is very useful during movie shooting.

It's important: unlike other lenses, where the aperture ring rotates with clicks, and the transition between any pairs of aperture numbers has the same step, the step between pairs of 7Artisans 55 / 1.4 numbers is always different. It is reduced from F / 1.4 to F / 16. This makes it difficult to conveniently and quickly set values ​​from F / 4 to F / 16. And for the F / 11 mark, there was no place on the scale at all (the distance between F / 8 and F / 16 is very small). In this case, F / 11 is present on the IPIG scale.

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.

Focusing

The focus ring is wide enough, metal, ribbed. The ring rotates approximately 135 degrees (3/8 of a full turn). The focus ring is poorly stretched from 1 meter to infinity. The focus is smooth and pleasant, the focus ring can be rotated with one finger. This is one of the few lenses that really captivates with its smooth focus. The last time I saw such a smooth focus on Carl Zeiss Distagon 2.8 / 21 ZF.2 T *. The smoothness of focusing, the oil stroke of the focusing ring, I like most of all in old Takumar manual lenses, for example, in Super-Multi-Coated TAKUMAR 1: 1.8 / 55 ASAHI OPT. CO., JAPAN. When I first picked up the 7Artisans 55 / 1.4, I immediately remembered my favorite for the smooth focus Super-Multi-Coated TAKUMAR 1: 1.4 / 50 ASAHI OPT. CO., JAPAN.

It's important: After successful focusing when trying to set the desired aperture value, you can easily touch the focus ring, which rotates very easily and thereby bring down the exact focus.

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

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 only 35 centimeters, and the maximum magnification ratio is approximately 1: 5.5. Such an MDF is not characteristic of fifty-fifty lenses. Usually, a minimum focusing distance of 50 cm is used for a 45 mm focal length. The small MDF of 7Artisans 55 / 1.4 is another nice side.

7Artisans 55 / 1.4 has a small 'Focus Breathing' effect (changes in viewing angle during focusing). During focusing towards the MDF, the viewing angle decreases.

Focus Shift (focus shift, changing focus distance due to iris)

Have a hard stop (hard infinity mechanical stop) for fast and accurate aiming at infinity under any temperature operating conditions. On the copy from the review, the hard stop works as expected, without a flight.

Image quality

7Artisans 55 / 1.4 is pretty 'nice' on open diaphragms in terms of 'artistic' components. A classic planar-like picture typical of many old lenses catches your eye. At F / 1.4, the lens is not impressive, but if you just cover the aperture a little, sharpness returns to normal.

Sharpness

  1. at f / 1.4 the resolution is pretty low
  2. sharpness changes significantly with aperture up to f / 2.0
  3. a drop in sharpness to the edges and corners of the frame is insignificant, which is a rarity for inexpensive optics
  4. excellent center resolution occurs after f / 2.8

Distortion

  1. there is a small barrel-shaped distortion
  2. easily fixable in the editor and almost invisible in the pictures

Vignetting

  1. noticeable vignetting observed most strongly at f / 1.4
  2. vignetting decreases with focus towards MDF. Most noticeable when focusing on infinity
  3. vignetting almost disappears at f / 2.8
  4. vignetting easily fixable in the editor

Aberration

  1. strong chromatic aberration over the entire field of the frame, but appear only in highly contrasting details (example)
  2. strong milling

Rest

  1. on covered diaphragms, a beautiful effect of a 14-ray star is difficult to achieve due to the strongly rounded opening (example)
  2. from bright light sources you can get a lot of glare, while they can be of enormous size (example)
  3. bokeh is interesting, but a bit 'nervous'

Important: at the time of the creation of this review, there was no 7Artisans 55 / 1.4 profile for popular RAW converters. You can create a profile yourself or wait for its release.

My experience

I was already in Radozhiv 7Artisans 55 / 1.4 review by reader, but in the version for the Micro 4/3 system (crop Kf = 2.0), with which I practically agree with everything. I was asked to prepare a separate review on cameras with an APS-C sensor.

7Artisans 55 / 1.4 - a manual alternative to the native Sony E 50 / 1.8 OSSas well as an alternative for Sigma 56 / 1.4 DN C and Viltrox / Tokina 56 / 1.4. First of all, 7Artisans 55 / 1.4 is used for creative, artistic photo tasks, including portraiture.

It is difficult to fall into sharpness at F / 1.4, only a strong increase in the selected part of the frame (the so-called magnifying glass) helps. Focusing on focus picking at 1.4 is quite a risky activity, you can’t get sharpness in the right place on the picture.

On F / 1.4 it is convenient to shoot objects at a distance of no more than three meters. At the same time, the visual perception of images does not suffer much from weak sharpness. But at long focusing distances, weak sharpness becomes much more noticeable.

An additional 5 mm of focal length almost always looks more advantageous than the classic 'pure' fifty dollars. The EGF of such a lens on cameras with an APS-C sensor almost exactly corresponds to 85 mm, which is a classic portrait focal length.

Among the old manual full-frame lenses, there are also many 55 / 1.4 class solutions, for example, Auto mamiya / sekor 1: 1,4 f = 55mm. But still, most of the old inexpensive 50-55 / 1.4 class lenses will not be better than the modern 7Artisans 55 / 1.4. First of all, this concerns enlightenment not optimized for digital cameras, which affects contrast and color. And also I don’t remember a single old man 50-55 / 1.4 with 14 diaphragm blades.

7Artisans 55 / 1.4 is pretty interesting. It was a very good idea to release a compact fast-moving fifty dollars optimized for APS-C sensors.

For about three weeks now I have in my hands one of the best lenses from Minolta - MC ROKKOR 1: 1.2 f = 58mm of the latest version. I should note that despite its F / 1.2 and legendary status, working and having fun and the result is much easier and more enjoyable with 7Artisans 55 / 1.4 (I used both lenses on the Sony a3500). This can only be my experience and it may not be connected in any way with the real state of affairs, especially since ROKKOR is designed for full-frame SLR cameras.

Video review

Results

7Artisans 55 / 1.4 - a modern manual fast aperture fifty. Has a good price / quality ratio. Some optical imperfections are offset by low cost and quality assembly. Compact, with 14 aperture blades. It can serve as an excellent creative solution for amateur photographers.

10 main advantages

  1. low price tag (total about 100 dollars)
  2. maximum aperture F / 1.4 (very high aperture)
  3. additional 5 mm of focal length compared to classic fifty-fifty (55 mm versus 50 mm)
  4. very good build quality: the lens body is completely made of metal
  5. very smooth focus ring, pleasant to use
  6. there is a depth of field scale and focusing distances
  7. 14 diaphragm blades that always give a rounded hole
  8. the aperture ring rotates smoothly, without intermediate values ​​(important for movie shooting)
  9. the aperture control ring is located in front of the lens, which is very convenient
  10. good sharpness in the center already at F / 2 and good at more covered apertures, good control of vignetting and distortion

10 main disadvantages

  1. no CPU pins to form the correct EXIF
  2. rather rare thread for a 49 mm filter
  3. a threaded (non-bayonet) hood should be used; no hood is included in the scope of delivery
  4. a small step at the aperture ring between the aperture values ​​F / 4-F / 16. The aperture ring is easy to accidentally hook and knock down the set value, the same goes for the focus ring
  5. focus ring poorly stretched from 1 meter to infinity
  6. there is no lens profile for popular RAW converters, the lens is not 'wired' into modern cameras
  7. old optical design, ordinary Gaussian double lens, Planar with 6/5 scheme
  8. in backlight or side light you can easily get strong glare
  9. tangible chromatic aberration
  10. low sharpness at f / 1.4

Comments: 15, on the topic: Review 7artisans 55mm / f1.4 (Sony E-Mount)

  • Molchanov + Yuri

    Thanks for the review! During the quarantine period, you have brought down tons of useful information on our heads!

  • RussTamblyn

    There is a hard stop (hard infinity mechanical stop) for quick and accurate focusing under any temperature operating conditions.
    To infinity?

    • Arkady Shapoval

      Fixed

  • Pavel + Gorbunov

    EXTREMELY !!

  • Eugen

    Carl Zeiss Distagon 2.8 / 21 ZF.2 T * Was it on the review?

  • UstasFritZZZ

    Thanks for the review! I really liked the lens, it would be strange to expect Zeiss quality from it at a price of a hundred dollars. By the smoothness of the focus ring, I personally really like the Minoltovsky MD 50 F1.4, maybe I just got it, but it works like clockwork - it’s amazingly simple, it has one minus - 6 aperture blades, it covers at least a little from 1.4 and get the nuts It's a shame.

    • Oleg

      I confirm! Sometimes you take it in your hands and unnecessarily want to twist the focus ring, so oily smoothly :) which the same popular Olympus Zuiko OM 50 / f1,8 does not have, at least for my copy. I also agree about nuts, but on f2 I often do not notice them. And sometimes I remember from them what was filmed, I’m specifically looking for :).

      • Gregor

        Well, my bunny is spinning very nicely.
        However, the minolta too)

      • Vlad

        Regarding the smooth running of the ring: on many lenses with a stepper motor and an electronic ring, it is made very comfortable. For example, on a cheap Nikon 18-55 af-p kit, the focus ring is surprisingly smooth, oily and pleasant

        • Arkady Shapoval

          yes, that's right, that's just electronic, without tangible feedback

  • Vladimir

    Helios 44m-7 will not be more interesting?

    • Arkady Shapoval

      Someone will be more interested. But overall, no. Especially in the crop. But in the case of 7Artisans 55 / 1.4, we can only talk about crop.

      • Vladimir

        Thank you!

  • Vadim

    Sonya has some strange colors, ugly (IMHO, of course).
