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 in the world. This is rare. At least it's cheaper than America and Japan.

This mirror is very common in domestic P-powder eyes. 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 that you can shoot at the object. The bright large aperture of 2.8 is very cool.

Da 15 mm /4 limited

This mirror has a suffix. What does this limit mean? This is a proper name of Pentax, called limited edition. In fact, it refers to the monthly production quota, not the real limited edition.

The designer of this mirror is Kang. He is also a very popular designer in the P family, and he has his own unique views on wide-angle lenses.

This mirror uses an AL aspherical lens. The aperture is also very small, many people will laugh at P, and even F4 is also called the big aperture.

However, the biggest advantage of this kind of mirror is that it is small. Since it is limited, another feature of limitation is small. P is famous for its smallness, and its concept 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 at all. In the laboratory evaluation, the central resolution is surprisingly high, which exceeds the limit of the resolution target.

Small+high quality = high value

At present, the price of this kind of mirror is more than 4000 yuan. However, the United States 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 is limited.

Designer: Hirakawa Chun

As a wide-angle mirror, in today's large-scale use of aspherical lenses, this mirror actually adopts a symmetrical structure. Full-open image quality is guaranteed, and the biggest advantage of symmetrical design is small distortion and uniform image quality.

As a limited edition, this mirror is naturally very small. As one of the three biscuits represented by Pentax, you can imagine its size, and the very distinctive hood will make you feel low-key and luxurious.

Compared with 15, its price is about 2700.

Fa311.8 Limited Edition (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 strange focal length of this mirror. We'll talk later.

Let's talk about 3 1. Hirakawa was the designer of this mirror in the early days. In fact, Hirakawa designed 3 1 according to the idea of 2 1, and the maximum aperture can only be 2.4. The boss resigned, removed Hirakawa and replaced him with another team. Only the large aperture of 1.8 we see today, but at the cost of this limitation, the aperture is 58.

C-series 35L, N-series 35G and S-series 35G are all 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 ground aspheric mirror is used in this mirror, which is the most advanced 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, so as to correct the problem of image quality degradation in close range.

In addition, Jiao Wai, Jiao Wai and 3 1Lim can be compared or even better than C's 35L. This is a public opinion, whether on the other side or in Japan. This is almost the best part of Japan's 35 coke.

DA35/2.8 Acer Co., Ltd.

Designer: or Kang.

Before Sony's 30 macro lens appeared, it was almost the only macro lens with a focal length of 35. Lao Lin's workmanship and small caliber are absolutely addictive. Some people call it the best lens for shooting food. The focal length is appropriate and the lens body is low-key, which is really good.

DA35/2.4

Designer: unknown, but according to the published structural diagram, it comes from the current director of Nikon's second design class. He jumped from Pentax to Nikon's Quanshui Longji.

The reverse telescopic design of 6 pieces and 5 groups is quite satisfactory.

The center resolution is very high, close to the chart 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 so far I haven't seen it.

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 this mirror is extremely rich in hair color. Mowgli's CAPSS executives say it may be the SP coating.

DA40/2.8 Limited

Designer: Hirakawa Chun

In fact, this mirror is from Pentax designer Yutaka Takahashi of 1978.

Hirakawa modified the curvature of the first and last piece of glass to change the nearest focus from 0.63m to 0.4m..

Sonna structure with 5 pieces 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 the 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 of15mm and a weight of 90g.

When it is installed on the fuselage, it won't even come out of the flooded roof, just like it is not installed.

It's small and portable.

FA43/ 1.9 limited edition (big princess)

Designer: Hirakawa Chun

I don't know if the 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. That was in 2008, when the Japanese man was 46 years old.

"43", also known as "big princess", was released 1997, and Pingchuan was 35 years old.

This mirror has too many functions. Simply put, it has a strong center and soft corners, but after getting 2.8, it is out of the chart.

It is called the standard mirror in Japanese standard mirror, which 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. Since then, 5065438+

DA☆55/ 1.4

Designer: Hirakawa Chun

This is the last mirror of Hirakawa in P, because TAG Heuer fired Hirakawa shortly after its release.

Hirakawa, who was forced to be laid off early, was 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 this mirror to be 85 heads. In addition to using 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 complete circles.

In addition, this kind of mirror adopts Schneider's idea, that is, the low pass in front of CCD is only regarded as the back group of the lens at 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 light reflection in a wider wavelength range, improve light transmittance, and greatly reduce glare and ghosts that affect imaging).

Speaking of coatings, in 197 1, P has been ahead of the industry since the development of smc coatings. 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 paint is a patent of Hoya after he became a shopkeeper. I don't know if I can take it with me this time, but I'd better take it with me.

And 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

I seem to be writing a biography for Pingchuan Chun tonight.

6 pieces and 5 groups of plane structure, fully open, with many advantages. The evaluation of PZ even exceeds that of Princess Qiqi in some places, and the purple edge control is even better! One of the few recommended avatars on PZ, the price is approachable, and it is a good portrait.

FA77/ 1.8 Co., Ltd.

Designer: Hirakawa Chun

The mirror has 7 blocks and 6 groups of planar structures.

There is a free design, which is great.

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 festivals, so Hirakawa made this strange head portrait.

In fact, this focus is 75 14 from France Aineng Exhibition, 751902AA from Leica, 85 14 and 85 12 from Kangtai, 85 12 from Canon and 85 12 from P's own A star.

If you sell the front pass, you should say Pingchuan Chun.

From now on, 1984, 22-year-old Hirakawa Chun released A-star 85 1.4, which is the best 85 14 avatar of any era. Because it is designed with free, the full-open resolution is very good, even better than 85 14 of Kangtai Zeiss.

Then FA Star 85 1.4 (Famous Cup, Star Bar Dance), Hirakawa challenged himself to use two pieces of high-sawtooth low-dispersion glass, which is one of the best L-material mirrors in Japanese 85 (Minolta 85GDL is silent), and the back group focuses quickly, which is very characteristic of the autofocus era.

FA77 of 1998, Second Princess, Pingchuan once again challenged herself and got back the free design, with excellent performance and great strength.

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.

Also explain the name first, this DFA is a digital head that can be used for film. Actually, it means Quan Huafu Mirror. In fact, 40 and 70 of them can be played on Quan Huafu.

A 100 micro-single is the best, then F 100 micro-single, then FA 100 micro-single, and then DFA 100 micro-single second generation, that's all. Of course, the head of this all-metal mirror is beautiful, with a simple waterproof and practical head.

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.
