In short

7Artisans 50mm 1: 1.05 is a modern manual (manual focus only) high-aperture prime lens for full frame mirrorless cameras.

7Artisans 50mm 1: 1.05 is interesting for its very high-quality assembly, a large number of aperture blades and a maximum relative aperture of 1: 1.05. At the same time, at F / 1.05 in the center of the frame, the lens shows quite a passable result. There are questions about the real light transmission of 7Artisans 50mm 1: 1.05 - most likely the real aperture is at f / 1.2.

Among the shortcomings are the standard optical problems inherent in such inexpensive high-aperture optics, first of all, noticeable freezing and poor performance in the backlight.

50mm is a very common and popular focal length. High-aperture fifty kopecks are very common and are used by a large number of photographers for a very large variety of photographic tasks.

7Artisans 50mm 1: 1.05 uses the rare f / 1.05 aperture (hundredths of f-number are indicated).

  • F / 1.05 aperture 3.63 times wider than F / 2.0 aperture
  • F / 1.05 is 2.94 times wider than F / 1.8
  • F / 1.05 is 1.78 times wider than F / 1.4
  • F / 1.05 is 1.31 times wider than F / 1.2
  • F / 1.05 is 1.1 times wider than F / 1.1
  • F / 1.05 is 1.1 times narrower than F / 1.0
  • F / 1.05 is 1.22 times narrower than F / 0.95

Assembly

The lens came to the review completely new, in a sealed box. The box contains the lens itself with front and back covers, a case-tube and a small instruction. In the middle of the box there is a large and soft foam niche and an additional arch-shaped foam retainer. The design of the box is stylish and beautiful. Initially, the box is surrounded by an additional beautiful cardboard wrap, which serves as a kind of seal. The manual contains a coupon page with warranty obligations. On the inside of the case lid there is a pocket for memory cards. Zippered lid with '7Artisans' logo embossed on top. The wardrobe trunk has two carabiners for a strap and a separate fastener for a belt.

In general, the lens very well assembled... 7Artisans 50mm 1: 1.05 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 50mm 1: 1.05 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.

The case design is similar to the models 7Artisans 28mm F / 1.4 и 7Artisans 75mm F / 1.25.

All marks and labels 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. When using light filters, the cover becomes useless. If you put the lens with the front cover down on the case, then the cover can get stuck there and it will be very, very difficult to get it out of there.

The weight of the 7Artisans 50mm 1: 1.05 lens itself is about 600 grams. In the hands, the lens feels like a solid thing.

The filter diameter is only 58 mm.

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 used 1 more petal. 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, which is very useful during video shooting.

It's important: unlike other lenses, where the aperture ring clicks, and the transition between any pairs of f-numbers has the same step, the step between the extreme pairs of 7Artisans 50mm 1: 1.05 numbers is always different. It shrinks from f / 2.8 to f / 16. This makes it difficult to conveniently and quickly set values ​​from F / 2.8 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 it. I did not observe accidental changes in the aperture value or focusing distance due to carelessness.

7Artisans 50mm 1: 1.05 APO

What is the actual aperture ratio (T-stop) at f / 1.05?

The light transmission of the lens is expressed 'T' steps... It is this value that is considered to be the real indicator of the lens 'aperture'. Usually T-stops (T-feet) are interconnected with the stops of the aperture (F-feet). Quality lenses have fairly close numbers around 'T' and 'F'. For example, a quality lens with a maximum aperture ratio of 1: 1.4 (aperture number f / 1.4) has a light transmission at the T / 1.5-T / 1.6 level. But light transmission of 7Artisans 50mm 1: 1.05 at f / 1.05 far from T / 1.05.

My observations of the behavior of the 7Artisans 50mm 1: 1.05 lens:

  • the lens has an incorrect aperture control scale... Between pairs of numbers F / 1.4 -> 2 -> 2.8 -> 4 -> 5.6 -> 8 -> 11 -> 16 Exposition must differ by 1 stop. But when going from F / 1.05 -> F / 1.4 -> F / 2 Exposition does not change according to the specified rule. The same applies to the transition F / 4 -> 5.6 -> 8 -> 11 -> 16. Only when maneuvering from F / 2 -> 2.8 -> 4 Exposition behaves predictably and has a clear step equal to one notch.
  • according to the following calculations, the difference between F / 1.4 and F / 1.05 should be almost a step: (1.4 * 1.4) / (1.05 * 1.05) = 1.78 times, or 0.83 steps [log (1.78,2) = 0.83]. When working with a 7Artisans 50mm 1: 1.05 lens with aperture maneuver from f / 1.05 to f / 1.4 Exposition decreases only by 1/3 stop... Differences in exposure are in the range of 1.2-1.3 times (on average, 1.25 times, or 1/3 steps, the steps are calculated as follows: log (1.25,2) = 0.32). The fall exposure I tracked the cameras using a spot exposure meter on a gray card (including in various shooting modes, as well as a histogram of the resulting images). And also I have done many tests with focusing at infinity and on MDF, with different shooting conditions, at different calibration values ​​of ISO and / or excerpts.
  • the f / 1.4 aperture mark on the aperture control ring gives an exposure that is nearly perfect exposure f / 1.4 aperture with lens MINOLTA MC ROKKOR-X PG 1: 1.4 f = 50mm... This is a manual full-frame aperture fifty-kopeck piece, which I had at hand, was installed on a Sony camera through an appropriate adapter without microprocessor contacts (so that the lenses would not be recognized by the camera and the electronics would not try to influence the exposure meter). Both lenses next to each other they look like this.
  • 7Artisans 50mm 1: 1.05 at f / 1.05 is only about 1.25 times (about 1/3 stop) lighter MINOLTA MC ROKKOR-X PG 1: 1.4 f = 50mm at F / 1.4.
  • 7Artisans 50mm 1: 1.05 at f / 16 about 10 times (about 2 stops) lighter MINOLTA MC ROKKOR-X PG 1: 1.4 f = 50mm at F / 16. So the 16Artisans 7mm's f / 50 is 1: 1.05 at f / 16 and is actually close to f / 8.
  • It is difficult to talk about exact values, since the aperture control ring on the 7Artisans 50mm 1: 1.05 lens rotates smoothly, without fixed and precisely defined values, and it is not so easy to find out at which angle of rotation the F / 1.4 or F / 2.0 value is. The slightest twist affects the final result. In addition, a different spacing between pairs of f-numbers is added here. Therefore, here I indicate everywhere that these are approximate values.
  • it turned out to be quite difficult to track the real F values ​​by depth of field or by the size of the disks of confusion due to the 'Focus Breathing' effect (changes in the angle of view during focusing). In general, 7Artisans 50mm 1: 1.05 at f / 1.05 blurs the foreground and background more than MINOLTA MC ROKKOR-X PG 1: 1.4 f = 50mm at F / 1.4. 7Artisans 50mm 1: 1.05 has a much more pronounced Focus Breathing than MINOLTA MC ROKKOR-X PG 1: 1.4 f = 50mm.
  • Ken rockwell measured the entrance pupil of the 7Artisans 50mm 1: 1.05 at f / 1.05, the diameter of which is approximately 41 mm, which gives us a relative aperture in the region of 1: 1.2-1: 1.3 (it is simply considered: 50mm / 41mm = 1.22). I want to note that of all the reviews that I have seen, only the old Ken seriously approached the question of the real aperture of the lens.

What follows from all this? Aperture F / 1.05 has light transmission in the region T / 1.4-T / 1.5... Such light transmission is usually obtained by high-quality lenses with an aperture ratio of 1: 1.2-1: 1.3.

At the moment, I believe that the miracle has not happened: 7Artisans 50mm 1: 1.05 should be considered as a lens with aperture / light transmission in the region of T / 1.4-T / 1.5 with the aperture set to F / 1.05.

I have already seen this behavior at the lens. 7Artisans 35mm 1: 0.95.

Below are the aperture readings and excerpts with the same ISO value when shooting with 7Artisans 50mm 1: 1.05 uniformly lit space (tripod, focusing at infinity):

  • F / 1.05 <-> 1/3200
  • F / 1.4 <-> 1/2500
  • F / 2 <-> 1/1600
  • F / 2.8 <-> 1/800
  • F / 4 <-> 1/400
  • F / 5.6 <-> 1/320
  • F / 8 <-> 1/200
  • F / 11 <-> 1/160
  • F / 16 <-> 1/80

Focusing

The focus ring is wide enough, metal, ribbed. The ring rotates approximately 120 degrees (about 3/8 of a full turn). The focusing ring is poorly stretched from two meters to infinity.

Focusing is not very smooth. During focusing, there is no pleasant oily-smooth movement, like, for example, the lens 7Artisans 55 / 1.4... During focusing, the focus ring creates a slight and characteristic hum (the lens hums slightly). If the lens is not used for a long time, the focusing ring freezes and needs to be developed. To do this, just twist a couple of times all the way in different directions. When used in the sun (when the lens is very hot), the hum disappears. In cold weather, the focusing ring rotates tighter.

During focusing, the trunk of the lens runs forward but does not spin... Together with the trunk, the diaphragm control ring also comes out. During focusing, the rear lens also moves, but at a much shorter distance. Most likely, the hum from the focusing ring is associated with the complex implementation of the focusing method with floating elements.

On the ring there is a scale with a focusing distance in meters and feet and a depth of field scale. The depth of field scale is most likely too wide for a 50mm lens (measured with a very large disc of confusion).

The minimum focusing distance is 57 cm and the maximum magnification ratio is approximately 1: 8 (measured).

7Artisans 50mm 1: 1.05 has a noticeable 'Focus Breathing' effect (changing the angle of view while focusing). When focusing towards the MDF, the angle of view decreases significantly.

Focus Shift (shift focus, change of the field of focus due to aperture) is absent.

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 at f / 1.05 works well, but still it is not easy to get into sharpness perfectly.

Image quality

7Artisans 50mm 1: 1.05 is pretty good, although it has obvious serious problems. At F / 1.05, the lens does not have high optical performance, but still surprises with good sharpness.

Sharpness

  1. at f / 1.05, the resolution is not bad (much weaker lens behavior at f / 1.05 was expected, but here the 7Artisans 50mm 1: 1.05 was a pleasant surprise)
  2. drop in sharpness to the edges and corners of the frame, but some terrible nightmare in the corners and edges of the frame is not observed
  3. sharpness changes slightly with aperture cover up to f / 1.4, only after f / 2 a high resolution is achieved in the center of the frame
  4. edges and corners of the frame come back to normal only on very closed apertures
  5. there is a palpable coma

Distortion

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

Vignetting

  1. weak vignetting at F / 1.05 (which was very, very surprised)
  2. vignetting decreases with focus towards MDF. Most noticeable when focusing on infinity
  3. vignetting almost completely disappears at values ​​after F / 2
  4. vignetting easily fixable in the editor

Aberration

  1. chromatic aberration well corrected in the center of the frame, but significantly enhanced towards the edges and corners of the frame (prefix APO [apochromat] in the lens name is not justified)
  2. there is strong frying (spherochromatism), which colors contrasting elements in the out-of-focus area in green / green-blue and red / red-violet colors

Rest

  1. at closed apertures in the area of ​​F / 8-F / 16, you can achieve a weak effect of a 26-ray star
  2. from bright light sources you can get a lot of glare, while they can be of enormous size. Significant loss of contrast is possible when shooting in backlight and side light (example)
  3. bokeh is pleasant in many cases. Discs of confusion to the edges and corners of the frame turn into 'lemon' a little, sometimes they can be cut off. But in general, the lens does not have any specific 'pattern'

Important: at the time of writing this review, there was no 7Artisans 50mm 1: 1.05 profile for popular RAW converters. You can create a profile yourself or wait for its release.

Sample photos on a camera with a Full Frame sensor

All photos in the gallery below are shown without processing. Camera used Sony α7 III with 24 megapixel full-frame Exmor R BSI CMOS sensor. All photos are on-camera JPEG without any manipulation of settings. Standard Picture Control with zero corrections for sharpness, contrast and saturation. All images at ISO 50 were taken at f / 1.05, all images at ISO 100 were taken at f / 2.8.

Sample photos on a camera with an APS-C sensor

All photos in the review below are shown without processing. Camera used Sony a3500 (Sony Exmor APS-C HD CMOS 20MP sensor). The pixel density is higher than that of Sony a7RII, a7R III... All photos are on-camera JPEG. Some sample photos were taken using a polarizing filter. Hoya 58mm PL-CIR... At ISO 100 (the lowest possible for this camera), shutter speed 1/4000 second (the lowest possible with this camera) and f / 1.05 on a sunny day, you can very easily overexpose the frame. Polarizing or ND filters are very helpful in dealing with this problem. With a light filter, there is only one inconvenience - the original cover does not hold on to it, it is best to get any classic snap-on cover (for example, this).

Original images in JPEG format can be viewed and / or downloaded at this link (130 photos, gallery on Google Drive). Original images in RAW format (Sony '.ARW) can be viewed and / or downloaded at this link (20 files, gallery on Google Drive).

EGF of such a lens on cameras with an APS-C sensor corresponds to 75 mm, which is close to the classic focal length for portrait photography. And the equivalent aperture in terms of depth of field is F / 1.58.

A little more photos can be found on Radozhiva's social networks: 1, 2, 3, 4, 5.

My experience

I worked with this lens for about a month and shot with it for about 7000 frames. Getting into sharpness at F / 1.05 is not that difficult, perhaps due to my many years of fascination with manual optics. The defect rate due to incorrect focusing is low and similar to other similar lenses (e.g. MINOLTA MC ROKKOR 1: 1.2 f = 58mm).

It's a shame that the 7Artisans 50mm 1: 1.05 instead of f / 1.05 has real value around f / 1.2. I have already seen this behavior in 7Artisans 35mm 1: 0.95... Apparently F / 1.05 is a certain psychological trick. It could just as well have been the '7Artisans 50 / 0.95' lens, but apparently competition with a more expensive TTArtisan 50 / 0.95 nobody needs it.

It's funny that the APO attachment is only used on the box in which the lens is shipped. 7Artisans 50mm 1: 1.05 itself does not have the 'APO' marking. Of course, this lens is far from a high-quality apochromat.

The design of the 7Artisans 50mm 1: 1.05 optical scheme is generally quite simple and is based on a conventional double Gaussian lens (Planar 6/5 modification). For example, such a planar-like scheme is used for the lens 7Artisans 55 / 1.4... A speed booster scheme has been added to this scheme. The same principle is used by many similar lenses, for example, TTArtisan 50mm F / 0.95 DJ-OPTICAL ASPH (similar arrangement of 6/5 and 'booster'). Truth, the booster is well integrated with the whole circuit here... This can be clearly seen from the fact that during focusing, a method with floating elements is used - different groups of lenses / lenses are shifted at different distances. In the case of a simple docking of a group of booster lenses, we would just get a fixed rear part.

For work, I would rather prefer some kind of autofocus lens of class 85 / 1.8, which, even at F / 1.8, distinguishes objects of shooting (blurs the foreground / background) no worse than 50 / 1.05. At the same time, 7Artisans 50mm 1: 1.05 can act as a non-trivial light fifty dollars.

In general, the 7Artisans 50mm 1: 1.05 is in many ways no worse than the old 'legendary' manual lenses of the class 50/55/58mm with f / 1.2. The question remains only in tastes. According to the picture, I am most interested in the modern 7Artisans 50mm 1: 1.1, which is built according to the Zonnar scheme (and not the Planar, like this one 50 / 1.05). I did not find anything fascinating in the picture of 7Artisans 50mm 1: 1.05.

A variety of particularly fast modern Chinese lenses can be found in the 'High speed lenses'.

Video review

A brief video review of the lens can be viewed on my Youtube channel or lower:

Results

7Artisans 50mm 1: 1.05 is an interesting creative tool. It is quite usable at f / 1.05. There are questions about the real aperture ratio. Strong spherochromatism is present. Very well put together, but the focus ring is not very smooth. 7Artisans 50mm 1: 1.05 is a good alternative for old classic manual solutions of class 50/55/58 / 1.2.

10 main advantages

  1. low price tag (you can find everything for $ 470 with free shipping)
  2. high aperture (declared aperture ratio 1: 1.05)
  3. very good build quality: the lens body is completely made of metal, the package includes a stylish case
  4. there is a DOF scale and a focusing distance scale
  5. 13 diaphragm blades that always give a rounded hole
  6. the aperture ring rotates smoothly, without intermediate values ​​(important for movie shooting)
  7. the aperture control ring is located in front of the lens, which is very convenient
  8. use of two ED elements in the optical scheme
  9. acceptable sharpness in the center of the frame at F / 1.05, weak vignetting at F / 1.05
  10. the lens can severely blur the foreground / background at close to medium focusing distances

10 main disadvantages

  1. according to my measurements, the light transmission at f / 1.05 is at the level of T / 1.4-T / 1.5 (typical for f / 1.2-F / 1.3)
  2. incorrect marking of the diaphragm control scale
  3. no microprocessor contacts to form the correct EXIF on the received pictures
  4. a threaded (non-bayonet) hood should be used; no hood is included in the scope of delivery
  5. small step at the aperture ring between the values ​​of the aperture numbers F / 2.8-F / 16
  6. the focusing ring does not have a pleasant smooth movement (for example, as in 7Artisans 55 / 1.4)
  7. heavy weight (about 600 grams)
  8. there is no lens profile for popular RAW converters, the lens is not 'hardwired' into modern cameras
  9. strong milling
  10. bad behavior backlit

Comments: 13, on the topic: Review of 7Artisans 50mm 1: 1.05 APO

  • Igor

    Pardon the noob question:
    is there a real opportunity to use such lenses
    with the D800 camera?

    • Rodion

      No, it won't. Thanks to the diameter of the F mount - especially bright optics cannot be made for it. Take BZK or Canon - it has Mitacon 50 / 0.95.

      • Evans

        at least somewhere a boot is needed)

    • Arkady Shapoval

      Unfortunately, there is no such possibility. This lens is only for mirrorless cameras (it cannot be installed on SLR cameras in principle). But for the D800 there is the Nikon 50 / 1.2 AI-S. If you want something from modern Chinese high-aperture solutions for Nikon full frame, then take a look at KamLan 55mm F / 1.2.

  • Natalia

    Nice picture, and clear and contrasting.

  • Sergei

    I think it's just a 50 / 1,2 lens, but the cunning Chinese painted 1,05 on the body for marketing reasons.

    We are waiting for a crowd of lenses with aperture of 0,45, yeah.

    • Rodion Eshmakov

      And there is. Chinese manufacturers have turned into optical gypsies. I'll have to drive them 50 / 1.1 better. Although the pupil there really corresponds to 1.1-1.2.

  • in

    An even picture, mirror analogs are nervous, but here exactly

    • Rodion Eshmakov

      High-aperture lenses for CZK, not based on calculations from the 50th century, also have quite an even picture. The same notorious Zenitar 1.2 / XNUMXs, which, although under the crop, is a very suitable example.

    • Arkady Shapoval

      For some, 'even' means 'bad'. Sometimes users want a special 'mesmerizing' picture from a particularly bright lens. But these parameters are usually loosely coupled. And the more modern the lens is, the more 'correct' and 'even' its picture is. In general, it is a blessing

  • Vadim

    I will add one of the advantages: a very beautiful blur in the out-of-focus area, in the background, it draws watercolors from the branches, in some way resembling the blur of film lenses.
    Among the shortcomings: the detailing as a whole could have been more, but, given the excellent "bokeshka", the ratio of sharp and unsharp is quite working; As for freezing, it is not so strong (but it is), in particular, I give a comparison of the subject in a full Sony frame with Laowa Argus CF 33 / 0.95 APO for Fuji-X, which, oddly enough, is slightly inferior to the subject in: blur, frigging and the beauty of boke? although the latter is of course purely individual.

  • Vadim

    Another example from the workers.

    • Arkady Shapoval

      Thank you
