"Hongkong Meike Digital Technology Co. Ltd" and "Neewer Technology Ltd." are in 1993 and 2010 founded chinese companies, based in the million city of Shenzhen in the south of the People's Republic of China, nearby Hongkong. Interestingly, the business addresses of both companies are located in the same street in Shenzen. What does that mean?  Who knows ;o)

A beneficial advantage and at the same time the reason for rising sales figures for the mirrorless cameras is undoubtedly their compactness. At the same time, the light intensity of adequate lenses requires many correspondingly annealed optical lenses with an increasingly complex design in mutually displaceable groups. Weight savings are possible through the use of plexiglass or chalcogenide glasses, although this is partly due to higher prices in the production process. On the other hand, the manufacturers are looking for new, lighter carrier materials made of engineering plastics for the lens bodies.
Except for the missing autofocus, the Neewer / Meike lenses fulfill these requirements almost perfectly: they are extremely compact, light and nevertheless light-fast. Here is a comparison of the size between the Neewer 28mm f / 2.8 and other equally strong lenses from my Old glass containers. Most are already quite small, but the NEX or mft necessary adapters relativize the small size considerably. The Neewer has a native Sony E-Bayonet and thus this wide-angle lens becomes a real pancake.

Left to right: Neewer 28mm/2.8, Hanimex MC 28mm/2.8, Vivitar (I) Auto-Wide Angle 28mm/2.5, Nikon AF-S 28mm/1.8

As a user of a camera with APS-C sensor, you notice that a 28mm lens on such a camera mutates into a 42mm focal length (full format). This can be used as a report focal range for street photography. However, the lack of autofocus for the Streetfotografie is sometimes very hindering.
At Microfourthird is even from the 28mm a 56mm focal range. Here Olympus and Panasonic has a quite large alternative with much higher light intensity.

Landscape surveys do not pose a problem, especially since it is usually stopped down strongly.
For close-up photographs, or portraits, but also for architecture, a sometimes strong barrel distortion is weakness. If you are photographing in the raw data format, the distortion in Adobe Lightroom can be corrected by a profile correction. Neewer does not provide any suitable lens profiles, so you have to look for a half-fitting profile correction from the Lightroom kit. Good experiences I have won with the lens profile of the Rokinon 35mm f / 1.4. Most distributions are well calculated.

The operation of the lens suffers a little under the narrow rings for focus and aperture adjustment. A real deficiency in the operation of the lens is the stepless adjustment of the aperture. Thus, even with a checking glance at the aperture ring, it is not possible to see what precise value was currently set. A "blind" adjustment of the aperture value by the conventional cracking with older lenses is thus practically impossible.

Let's get to the picture quality.
The sharpness in the center of the image is also very good to excellent with the aperture open. The compensation of the lenses prevents the usual coma effects and purple fringings with contrasting edges. Nevertheless, a sharp drop in sharpness can be seen towards the edges of the picture. This is negative for flat objects. However, already helps a slight fade to 4.0 in order to reach synonymous to the picture margins an acceptable sharpness. Of course, no comparison with a fixed burn beyond the 300, - Euro border, like my Nikon AF-S 28mm f / 1.8, but quite in competition with the usual suspects from the old glass container, like the highly praised Canon FD 28mm or the Olympus OM 28mm comparable aperture .

The contrast is at flare without flaw and blame, just like the resolution and the colors. The Neewer / Meike is neutral here and does not show any significant weaknesses even in the most problematic red or black.

Does the user of a Sony APS-C camera need a manual 28mm wide angle lens?
Alternatively, Sony and Sigma in this focal segment are the Sony SEL FE 28mm / 2.0 and the Sigma 30mm / 2.8 ART. Times apart from the zoom lenses (16-50mm / 3.5-5.6 OSS, 18-55mm / 3.5-5.6, 16-70 / 4.0 ZA OSS etc., etc.).
The main advantage with which Neewer / Meike can score is the really excellent price somewhere between 70 and 90 euro. However, there is the really good Sigma 30mm also from 150, - Euro (for mft already from 130, - Euro) and you have then as a bonus still an autofokus. The Neewer / Meike is very compact compared to the Sigma 30mm, but above all to the SEL 28mm / 2.0 very compact and due to the full metal construction is quite valuable.

Thus, the real added value of the Neewer / Meike 28mm f / 2.8 remains within narrow limits. If you have a very small budget and can or would like to live with the disadvantage of manual focusing, this lens has a cost-effective and compact alternative to the established fixed focal lengths.

To conclude, there are now a few photos I shot with the Sony-NEX 3N:

Hanimex (Automatic) MC 28mm f/ 2.8 - the worst lens in the world?

From this lens I have already collected a lot of information on the Internet. Most users comment critically to quite abjectly about this lens and you can really buy it for a song on EBay and the relevant forums. Very exactly I have with shipping pays 15 euros.

In a forum and also on Youtube, a often clicked hobby photographer has called this glass even the "worst lens in the world".  This is very violent. Anyway, I wanted to know it now and I bought it in a well-used condition in a forum.   As the photos show, the condition is quite good. The shutters are not oiled, they close perfectly. In contrast to newer lenses, these old treasures are always made of the full metal and make a very solid impression.
The focus ring is attached at the front and quite narrow. You have to get used to it. The individual apertures snapped firmly and clearly. You can work with the lens after some time without visual contact.

But let's start as usual with the technical data:

Manufacturer: Hanimex
Focal length: 28mm
Luminous intensity: F/2.8 – F/22 (other Copies with F/16)
Aperture: 6 or 8 lamellae
Bayonet: M42 and others, like MC/MD; Canon FD, Olympus OM, Pentax K, and so on (generally suitable for full frame, aps-c or mft)
Closest focusing distance: ca. 35cm
Dimensions: ca. 47mm x 60mm (Length x diameter)
Weight: ca. 218g
Filter thread: 52mm
Lens coating: Multicoated

Hanimex is an abbreviation for Jack Hannes Import Export, founded in 1947 in Sidney, Australia - Hanimex Corporation was an importer and distributor of cameras, lenses, and other photographic equipment in Australia and New Zealand. The company also distributed consumer electronics and other non-photographic gear. Hanimex cameras were often sold under the Hanimex brand name or co-branded with the Hanimex brand and the Manufacturers brand (e.g. Hanimex Topcon).  Photographic product distributed by the company were made by Tōkyō Kōgaku, Sedic and Royal in Japan, by Finetta, Montanus, Vredeborch and Dacora in West Germany, by Pentacon in East Germany, and by other manufacturers. Hanimex distributed SLR lenses for several different lens mounts under the Hanimex brand nameOn 22 April 2004 Fuji Photo Film Co., Ltd. acquired 100% of the shares of Hanimex.

My specimen is made for the Minolta bayonet, so with an MC or MD mount.
Minolta quality control in the 70s may have had very high demands. Because the picture quality, which I have found in my copy, is really unusually good. Yes, I am not afraid the Hanimex in some respects quite compare with my Nikon AiS or the new Canon FD in 28mm. From the price-performance ratio, you should be able to compare the Hanimex with the Sigma Mini Wide II. Although even for this early Sigma version, moon prices are now required, but some years ago you got such a Sigma 28mm f / 2.8 still thrown for ridiculous 20, - Euro.

However, my Hanimex seems to be somewhat decentered on the left. Maybe it has fallen down once or pasted somewhere.
Let us look at the picture quality for different light situations and motifs somewhat more precisely.

The following picture was deliberately developed with the shutter completely open. The focus point is on the connection to the right tap. The sharpness is striking even when the aperture is open. This contradicts all opinions on the Hanimex, which are widely used in the net. On the contrast edges you can see light purple colors. In Lightroom, however, this is immediately removed with a mouse click.The lens is actually multicoated.The bokeh is quite pleasant and quiet.

Stopped down lightly to f/5.6, the lens shows a good sharpness almost to the edges. Amazing. Even with backlighting the lens is pleasing and does not show too much optical problems. The flares are very reserved and not unpleasant.

If you consider that this object is usually priced between ten and twenty euros, this glass is really a treasure. My advice: before the purchase just a few sample photos shoot. Only then decide whether to buy or rather not. There was probably - especially with the M42 mount - very large quality differences in the production of the lens. My copy shows a remarkable sharpness and good picture quality. Also the resolution, the micro-contrast and the behavior in the case of backlight is above all doubt.
I can - contrary to the popular opinion in the Internet - this lens as a cheap solution only recommend.
