Da14mm /2.8
The designer is the most famous Pingchuan Chun of Pentax.
This mirror is a half-frame camera lens, not a Quan Huafu lens. The price is around 3500, which is the cheapest in China. This is rare. At least it's cheaper than America and Japan.
This mirror is very common in the eyes of domestic P fans. There is no AL aspheric mirror, but high folding glass and ED lens are used to correct the distortion caused by wide angle. It is said that this is an imitation of Leica m 19/2.8. But it is really rare in Japanese lens factory. The recent focus distance is very close, only 0. 17m, which means you can shoot at the object. The bright large aperture of 2.8 is very cool.
Da15mm /4 Co., Ltd.
This mirror has a suffix. What does this limitation mean? It's a proper name for Pentax, called limited edition. It actually refers to the monthly production limit, not the real limited edition.
The designer of this mirror is Kang. He is also a very prosperous designer of P family, and he has his own unique views mainly on wide-angle lenses.
This mirror uses an AL aspheric lens. Aperture is also very small, many people will laugh at P, even F4 is called big aperture.
However, the biggest advantage of this mirror is its compactness. Since it is limited, another characteristic of limitation is small. P is famous for its smallness, and its idea is that smallness is beauty. A small lens with a total length of only 5 cm and a filter aperture of only 49, who would have thought it was a wide-angle lens?
Such a low-key appearance, the quality is not bad, the laboratory evaluation, the central resolution is broken, exceeding the resolution target limit.
Small+high quality = high value
At present, the price of this mirror is more than 4000 yuan. However, America is relatively cheap. If you have a friend who enters this mirror, ask a friend to buy it, as long as you enter the customs.
DA2 1/3.2 Co., Ltd.
Designer: Hirakawa Chun
As a wide-angle mirror, the aspherical lens is widely used today, but this mirror actually adopts a symmetrical structure. Full open picture quality is guaranteed, and the biggest advantage of symmetrical design is small distortion and uniform picture quality.
As a limitation, this mirror is naturally small. As one of the three kinds of biscuits represented by Pentax, its size can be imagined, and the unique cigarettes will make you feel low-key and luxurious.
Compared with 15, its price is around 2700.
Fa311.8 Limited (Little Princess)
Careful readers will find that the name of this mirror is a bit strange. How can it be called FA? This is the lens prefix of the film automatic era P, indicating that this mirror is a full-length mirror.
Designers: Kang, Ito Takashi.
Look at the lens of P, without the magic and weird focal length of this mirror. We'll talk later.
Let's start with 3 1. Hirakawa was the designer of this early mirror. In fact, Hirakawa designed 3 1 according to the idea of 2 1, and the maximum aperture can only be 2.4. The boss quit, withdrew from Pingchuan and changed to another team. It just uses the large aperture of 1.8 that we saw today, but at the cost of this limitation, the aperture is 58.
Family C has 35L, family N has 35G, and family S has 35G, all of which are 1.4 specifications, while P seems to have only 1.8 aperture in this focal segment, but it is true that P regards him as a level with these 1.4.
P A frosted aspheric mirror is used in this mirror, which is the most upscale AL mirror. In the design, P's own free design is adopted, that is, the back group does not move, and the front group focuses to correct the problem of image quality degradation in close-up.
In addition, the ratio of 3 1Lim in Jiao Wai and Jiao Wai can be comparable to or even better than that in C's 35L. This is a kind of public opinion, whether it is the other side or Japan. This is almost the best of Japan's 35-focal profile.
DA35/2.8 Acer Co., Ltd.
Designer: or Kang.
Before Sony's 30 micro appeared, it was almost the only macro lens with a focal length of 35. Lim's workmanship and small caliber are absolutely addictive. Some people call it the best lens for feeding, the right focal length and the low-key lens body are really good.
DA35/2.4
Designer: unknown, but according to the published structural diagram, the current director from Nikon's second design class jumped from Pentax to Nikon's Spring Dragon.
The reverse telescopic design of 6 pieces and 5 groups is quite satisfactory.
The center resolution is extremely high, and it is close to the diagram when it is fully open. P In order to be cheap, the bottom is made of plastic. It is said that there are 12 colors on sale in Japan. But I haven't seen it so far.
Last year, Zhuomei. Com bought 999 dollars, which was worth it.
Compared with 35 1.8G of n, the central resolution is slightly better, the price is more approachable than 35 18G, but the aperture is smaller. It is said that the hair color of this mirror is extremely rich. Senior CAPSS of Mowgli said it might be the SP coating.
DA40/2.8 Limited
Designer: Hirakawa Chun
In fact, the origin of this mirror comes from Pentax designer Yutaka Takahashi of 1978.
Hirakawa modified the curvature of the first and last glass, so that the nearest focus changed from 0.63m to 0.4 m.
The Sonna structure with 5 blocks and 4 groups comes from the sky plug structure of Zeiss engineer in 1903. Sky plug consists of 4 pieces and 3 groups. After adding a lens, the inherent focus drift phenomenon of the sky plug has been corrected.
This is the smallest SLR lens in the world at present, with a total length of 15mm and a weight of 90g.
When it is installed on the fuselage, it won't even come out of the flashing eaves, just like it is not installed.
It's small and portable.
FA43/ 1.9 limited edition (big princess)
Designer: Hirakawa Chun
I wonder if readers are tired. Anyway, I am tired of playing Pingchuan. A few days ago, Google Pingchuan saw that this man was the best optical designer in Pingchuan for 20 years. It was 2008, and the Japanese man was 46 years old.
43, also known as big princess, released in 1997, Pingchuan is 35 years old.
This mirror has too many functions. Simply put, the center is strong and the corners are soft, but after receiving 2.8, it is out of the chart.
Known as the Japanese standard mirror, it makes people feel enlightened.
FA50/ 1.4
Speaking of 50 14 and Pentax, 1965, P improved the self-contained lens of 1959 with the double Gaussian structure of 55/ 1.8, absorbed a little experience of Schneider, and applied for the modern optical structure of 50 14. After that, 5065438+
DA☆55/ 1.4
Designer: Hirakawa Chun
This is the last mirror of Hirakawa in P, because Hirakawa was fired not long after the release of TAG Heuer.
Hirakawa, who was forced to be laid off early, is 48 years old.
I wonder if anyone has asked him to go back to work.
Because P doesn't have the whole picture, P designed the mirror to be 85 heads. In addition to four high-grade serrated glasses, this mirror also uses a special aperture for the first time to ensure that the aperture spots formed by all apertures before 2.8 are round.
In addition, this mirror adopts Schneider's idea, and the low pass in front of CCD is only considered as the back group of the lens on the middle frame head. Japan 135 mirrors are rare!
In addition, this mirror adopts Pentax's latest coating technology-ABC film (Aero Bright coating can effectively reduce the reflection of light in a wider wavelength range, improve the transmittance of light, and greatly reduce the glare and ghost that affect imaging).
Speaking of coatings, at 197 1 p, smc coatings have been leading the industry since they were developed. In the 1990s, the anti-ghost coating was specially designed for the Japanese National Police Agency to deal with the problem of not being able to see the photos clearly when dealing with headlights, so it is difficult for friends who use P-mirrors to see the glare of petty bourgeoisie. At the beginning of the new century, SP coating is oil-proof and waterproof, only C-class high-end mirrors are available, and P even has more than 200 short sleeves. ABC coating is HOYA's patent after he became a shopkeeper. I don't know if I can take it with me when I marry Ricoh this time, but it's better to hold it with * * *.
Moreover, the name of this mirror is ☆, which is the symbol of Pentax professional mirror, just like Canon's L and red circle.
At present, judging from Ricoh's move to update high-definition coated lenses, it seems that ABC no longer exists? Or the new wine in the old HD bottle?
DA70/2.4 Limited
One of the three kinds of biscuits. Designer: Hirakawa Chun
Tonight seems to be a biography for Hirakawa Chun.
6 pieces and 5 groups of plane structure, fully open, with many advantages. PZ evaluation even exceeds 77 princesses in some places, and purple border control is even better! One of the few recommended avatars on PZ, the price is approachable, and it is a good avatar.
FA77/ 1.8 Co., Ltd.
Designer: Hirakawa Chun
This kind of mirror has 7 pieces and 6 groups of plane structures.
There is a free design, which is awesome.
Say the name of 77 first. Pingchuan likes to eat a kind of cake with a happy word in its name. The happiness of Japanese people is very similar to the two July 7th, so Hirakawa made the head of this strange focus.
In fact, this focus is 75 14 in France, 751902AA in Leica, 85 14 and 85 12 in Kangtai, 85 12 in Canon and 85/kloc-0 in its own A star.
Let's say Pingchuan Chun for the suspense.
From now on 1984, 22-year-old Hirakawa Chun released A Star 85 1.4, which is the best 85 14 head in any era. Because it is designed with free, the full-open resolution is very good, even better than Zeiss' 85 14 in Kangtai.
Then FA Star 85 1.4 (Famous Cup, Star Bar Dance), Hirakawa challenged himself to use two pieces of high-zigzag low-dispersion glass, which is one of the best L-material mirrors in Japanese 85 (Minolta 85GDL Silent), and the back group focuses quickly, which is very characteristic of the autofocus era.
FA77 of 1998, Second Princess, Hirakawa once again challenged herself and got back the free design, which was excellent in all performance and very awesome.
Japanese man Hirakawa is so awesome that he can't get away with it.
TAG Heuer laid him off. Unfortunately, it may be because of Jiang Lang, but you can always bring new people. Hey!
What an evil capitalist system!
DFA 100 micro
Every family has a mirror.
Let me explain the name first. This DFA is a digital head that can be used on film. Actually, it means Quan Huafu Mirror. In fact, 40 and 70 of them can be played on Quan Huafu.
A 100 micro is the best, then F 100 micro, then FA 100 micro, then DFA 100 micro, and then DFA 100 micro second generation, that's all. Of course, the head of this all-metal mirror body is beautiful, simple and waterproof and practical.
Followed by Daxing 200/2.8 Daxing 300/4.
There is basically nothing to say, except that 300/4 is the latest 300 fixed focus, which is similar to the specifications of CN. I won't be wordy.
