The Tokina RMC 28mm f/2.8 - a small gem for little money?



Caveat: a smooth Yes to my own question in the title. I have many lenses with 28mm focal length tried in recent times. Some lenses, like the Sigma 28mm mini wide II were very impressive in the image quality. For other lenses, such as the Vivitar 28mm f/2.8, it was necessary to stop down before I really satisfied with contrast, sharpness and colors.
However, the Tokina RMC II 28mm f/2.8 is really a very impressive lens.



As with the wide angle Tokina RMC II 24mm f / 2.8 is also the 28mm lens already to very good use at open aperture.   The Tokina 28mm f/2.8 you can buy for less than 30 euros. And you get a really good lens for your little money.
Let's start with the statistical data: The Tokina 28mm is a very compact lens with dimensions 64 x 42 mm and a weight of only 160 grams. The minimum focus is 0,3 meter, it is a multi-coated lens with 5 elements in 5 groups. The filter size is 49 mm.  A beautiful lens to adapt to a sony-nex or sony a7.
What about the image quality?  Already at open aperture sharpness and contrast are very good. If you stop down only grows the depth of field.  I have the lens used in bad weather and sunshine. The sharpness and resolution were always excellent.
In some situations, such as for example in the back light, it is better to use a lens hood. Otherwise the performance of the lens is blameless. Or in other words: I can really recommend this lens. One gets an excellent performance for very little money. I hope you can see on my photos, for example, how good this lens really is.

The Vivitar Series 1 28mm f/2.5 - made by Kiron



Not wrongly applies the Vivitar-lens-series as one of the best lens series from the good old days. What is the origin of the name and company Vivitar? 1938 fleeing from Hitler, the German immigrants Max Ponder and John Best founded in Los Angeles a company for distribution of optical equipment. Ponder and Best first imported German-made photo equipment. After World War II, the partnership began to import cameras and photographic equipment from Japan. Since the early 60s the company sales still called "Ponder & Best Inc." different lenses of the Japanese company called Tokina. Tokina designed and manufactured the lenses and "Ponder & Best Inc." sold these under the name "Vivitar" throughout the world. The production of the lenses took over in the 70s, the Japanese companies "Kino Precision Industries", better known under the brand "Kiron" and the company "Komine". In Internet circulated the opinion that "Komine" was only an extended workbench of Kiron and not an independent company. You can see that a lens of "Komine" comes when the serial number begins with the number "28". The best lenses from "Vivitar" called "Series 1" descended assuredly from the Komine Co. Ltd. . In 1979 the company "Ponder & Best Inc." renamed in "Vivitar". Under the name "Vivitar" very many good lenses were designed and sold. But the company has then in the end of 80s completely missed the transition into the time of autofocus-cameras and particularly the transition into the digital photo era.  Later it was sold to the company Hanimex and produced until 2008 inter alia for the South Korean company Samyang.



The lens that I am presenting today, was made ​​by Kiron. Also available as a Panagor badged lens, Kiron made Vivitar 28mm f/2.5 dates from the mid 1970s. Here the specs:
The lens has 8 Elements in 7 Groups. The aperture range goes from f/2.5 to f/22 (in Konica- version to f/16).The minimum focusing distance is 300mm. It weights 11 and 1/4oz (318 grams). The length at Infinity is 2 and 3/8"  (60mm), maximum diameter are 2 and 1/2"  (63mm), the filter size is 67mm.

The lens is built like a tank. For a 28mm lens, the design is quite large. In addition, it is necessary an adapter if you want to use the objective. With a Sony NEX or Olympus E-M5 the whole construction is then already top-heavy.

Typical of the lenses from the 70s is the very solid lens body. The aperture ring snaps fed and safe, the distance can be adjusted very precisely. Such optics are built to last.

How is the picture quality? Well, at full aperture, the image-center is slightly sharp and contrasty. To edge sharpness and resolution falls off very violently. Only when you stop down to f 4 or 5.6, the image is uniformly good quality. The distortions are rather small. The lens can even be used on an APS-C sensor as a portrait lens. At open aperture i found a little bit purple fringing at contrast edges. The lenses otherwise are coated obviously excellent.

With Sony NEX-3N at f/2.5,  1/250s, ISO 200
With Sony NEX-3N at f/2.5, 1/60s, ISO 1000
And bottom line?  You can buy this lens on eBay or as a package with any camera for less than 30 Euros.  You should not have to pay much more even. Stopped down to f/4 or 5.6 the Vivitar 28mm/2.5 is a very good performer. And: stop down ist not a shame.  In low light, the lens is still even at full aperture acceptable performance. It is not as good as the Yashica 28mm/2.8 or the Olympus 28mm/3.5. Even the Sigma mini wide II 28mm/2.8 is better at full aperture.  You get what you paid for. And for 25 to 30 Euros you have made ​​a bargain and should give a chance to this lens.

Industar 61 L/D 55mm f/2.8 - the radioactive lens from Russia

The Industar lenses are very often discussed on the Internet. There are already a number of reviews and most speak very positively. From the well-known lens Industar 61 there are different variants with focal lengths from 53 to 58 mm depending on production run. All of this lenses were produced since the 30s of the 20th century in Russia. More specifically, in the Ukrainian city of Kharkov. The Ukraine was then a constituent republic of the Soviet Union, like Russia or Kazakhstan.  The factory in which the Industar lenses were manufactured was called FED. Exactly the same name got the cameras manufactured there. Here you see a typical FED-camera named "FED5c" from the 1950s, the time of cold war.  Good friends have given me the camera as a birthday-gift some time ago.


I have adapted the Industar lens on my SONY NEX-3N and try to take some photos with it. Here are two photos with the adapted lens at the little Sony:




The Labour Commune FED is an invention of the Russian pedagogue Makarenko. He has founded it in 1927 as "Trudkommuna imeni F.E. Dserschinskowo" in the Ukrainian city of Kharkov. The initials F.E.D. are first name, patronymic and surname of the bloody founder of the Soviet secret service "Cheka": Felix Eduardowitsch Dsherzinsky. The commune hundreds of orphans were brought up by Marxist ideas. This included the work of the children. The children worked in two four-hour shifts. Four hours of class and four hours of work. First the labor community produced furniture and from the middle of the year 1932, replicas of the German Leica cameras and Leica lenses. Many of the FED cameras was copies from the original german Leica III with M39 mount.

OK, first the statistics: the Industar 61 is a single coated Tessar variant with 4 elements in 3 groups, the filter size is leica-like 40,5 mm. It has six conventional blades. You can stop down it to f/16 or in other production types to f/22. The closest focus distance is typical for rangefinder- objectivs: uncomfortably  one meter. It is 38mm long and the greatest diameter is 54mm. It weighs only 129 grams.  "L / D" in the name of the lens indicates that the glasses were impregnated with the rare earth Lanthanum. Lanthanum is actually slightly radioactive. However, the radiation is less than the background radiation we are exposed on earth anyway. On every flight through the earth's atmosphere, the radioactive pollution is much higher. A visible sign of the radioactive impregnation of the glasses is the yellowing of the lens if you have stored it a long time in the dark. The Industar 61 L / D is supposed to have the same optical calculation ​​as the Elmar 50mm f/2.8 made by Leica since 1957.


The handling ist neat, distance and sharpness can be adjusted easily. On backlight, the lens is very sensitive. The colors and contrast are fading. Here is a detail from a photo. Approximately 60% circumcised. The light came from above right. You should use a screw lens hood for Leica.


What are Cons and Pros for using this lens? 
The price is very nice: you can get it together with a FED-Camera by EBay or every used-merchandise trade for less then 20 Euros. The M39 mount adapters for Sony-NREX or mft are slightly and slim. It has a pretty solid built quality and the colors are great, when you stopped down.
And the Cons? The sharpness really lacks. It is open very soft, you must stopped down to aperture 4 or 5.6 to get sharp images with good contrast and colors. It is very difficult to focus when the lens is adapted on Sony NEX, regardless of whether you use focus peaking or not. 
The bokeh is choppy but not unpleasant.
Here some pictures wide open. You can see here the softness, not only in the center.






And my conclusion? That is very difficult to say. For the low price, the lens is a very good choice. On the other hand, there are a lot of good lenses with a focal length of 50mm for a little money. Among them are really good pancakes, such as the Minolta MD 50mm f / 2.0. 
If you caught a good specimen and must pay very little money, then I would recommend it. Otherwise, other manufacturers also have very good lenses in this focal length.

The Minolta MD 50mm f/2.0 - Who needs it?

Minolta has brought many bright standard lenses out in his golden years. By far the best known and most popular was the 50mm f / 1.7. It was to have cheap, you got it in the same rule with the camera with it. Who then needed more quality for a lot more money had the choice: the MD Rokkor 50mm f/1.4 or the 50mm f/1.2. As a particularly sharp and high contrast even at full aperture applies the legendary Minolta MC Rokkor 58mm f / 1.2.  So who in hell are needs a light weak 50mm f / 2.0?




In Internet rumor is alive and kicking, the Minolta Rokkor 50mm f/2 with the optical calculation of Leica Summicron of 50mm/2 is identical. No one knows if that's true. Probably not.
In fact, the new version of MD-III is optically excellent. Whether on a APS-C sensor or full frame: Even at full aperture sharpness and contrast are blameless. The newer version was produced from 1981. It contains six lenses in five groups. Exactly this copy I have examined.
The minimum focusing distance is 0.45 meters. The filter diameter is 49mm.It weighs only 150 grams. The lens has a length of 36 millimeters and a diameter of 64 millimeters. The aperture can be adjusted from 2.0 to 22. It has six aperture blades for a interesting bokeh.


So now enough with the wretched statistics. Let's look at pictures. This photo above was photographed at open aperture. The sharpness and contrast are very good. Also in the peripheral areas of the image. The bokeh is a bit odd, but overall more balanced.



If you have one or two stop down the lens, the image quality is excellent. There is no color bleeding and no coma. The photos are squeaky clean. Of course you can reach with a Minolta Rokkor 50mm f /1.7 similar results. But the 50mm f / 2 Rokkor has its own charm. And he really is to buy for a song. You get this lens virtually nothing on EBay. It is screwed in many cases already on an old analog camera. If you got it so cheap, then use it! It is really good glass. Here's to look at photos from the last few days.

Cheap and compact: Konica Hexanon AR 40 mm / F1.8



The Konica 40mm from the 70s is a true classic. You get it often on second-hand markets together with any camera. The lens alone there are rare now. Nevertheless, it is also quite inexpensive. Even for a flawless copy should not pay more than seventy to eighty Euros. Some time ago, this lens was to buy already for twenty to thirty Euros Meanwhile, the price of good used lenses from the 70s and 80s are almost doubled and tripled. The reason for the price increases is the introduction of compact system cameras that are established on the market from Fujifilm, Olympus, Panasonic and Sony. Same time there was in the beginning only a few suitable lenses for the new system cameras. So the users had no choice than to adapt old lenses.  In the meantime, the big companies have not slept. Especially Olympus, in cooperation with Panasonic, many new and very good lenses has brought to market. With time so the gaps are closed. In the future may stabilize the prices of old used lenses. At a low level, of course.



Coming back to this lens. First, a few statistics:
The Konica Hexanon 40mm is a typical pancake from the 70s. It was released in 1979 as a Kit-Lens for the Konica FS-1 to the market (formerly called this a "standard lens"). It weighs only 140 grams and has a length of 27 millimeters.  It is made up of six elements in five groups. The filter diameter is 55 mm, the minimum focus distance is 0.45 meters or roughly 1.5 ft. The aperture can be adjusted between 1.8 and 22. Forty millimeters is no real standard focal length of 50 millimeters, but also no real wide-angle lens. Nevertheless, the image effect is very pleasant and natural. The angel of view is 56°.



The imaging quality of the Hexanon 40mm is extremely good. Even at full aperture the image is very sharp and relatively high contrast. The bokeh on the other hand is not particularly nice to look at. Above you can see a photo at full aperture and including a 100% detail. The Konica Hexanon 40mm f / 1.8 is certainly one of the sharpest lenses I've ever seen.  The image effect is very natural, there is no plunging lines. Distortions are not noticeable.  There's a little bit coma wide open, but improves nicely on stopping down one or two steps.


Many users report of rattling noises inside the lens body. In a german forum of photography a brave user has opened a 40mm- lens and found:  The noise coming from the diaphragm ring which is mounted on a rotating ring of small metal balls. In order to keep this move, the ring is not completely filled, so that the balls rotate when the lens is moved.


The Konica 40mm is generally quite sensitive to stray light and back light. This is because that the front lens is not immersed in the lens body. Look at the picture above this text. Therefore, there is a lens hood is recommended to use. In summary, I would recommend this lens for everyday use. For the 35mm format, but also to Crop cameras with APS-C sensors.

Racing pilots in their old flying machines



All over the world there are collectors and hobbyists who buy classic cars from parts and bring this back to life. There's a lot of time, effort and attention to detail in it. As a result, creates wonderful old cars and motorcycles. Almost as to look as if they were new. Here in Germany, of course in Thuringia, the collectors meet to race, to exchange experiences and mutually spare parts for sale. During such meeting I'm creeping around and have taken so many photos as possible. Here is a small selection. The photos were taken in the Sitzendorf (known for his great biker's meeting) and Saalfeld.
