The Hypergon is one of those "legendary" lenses which are relatively much more expensive today than when they were new - almost a century ago. In terms of "real money" - average worker hourly pay, or something, the price is about the same now... The fully equipped 60mm cost 120 Mark in 1910, which was a considerable sum.

They were made in 60mm, 75mm, 90mm, 120mm, 150mm and 200mm focal lengths. Two versions were available: with or without the "star shutter". This was a rotating star-shaped aperture thingy which when used for part of the exposure worked as a center grad - to combat the light falloff towards the corners.

Without the starshutter, the lens gave good results over a 110° field of coverage; with the starshutter in use this was extended to 135°. that mens that the 60mm was designed to cover a 300mm field - or 8x10" film size.

Since the lens is completely symmetrical, there is no geometric distortion. The construction is fairly simple with only two deeply curved elements, so resolution won't be as good as more complex modern lenses. But no modern lens has a 135° coverage, so there isn't really any alternative if that's what you need.

"The Hypergon has for several years held a unique place among wide-angle lenses on account of its incomparable covering power.  It is a symmetrical double anastigmat, consisting of two very thin hemispherical single glasses.  Astigmatism, spherical aberration and curvature of field are completely corrected, and the definition is sharp to the very edges of the plate.  The chromatic aberration is not corrected, but is eliminated after focusing by the use of the smaller diaphragm stop, f/31. The symmetrical design of the Hypergon insures complete freedom for distortion of straight lines.  The diminution of light toward  the margin of the image, unavoidable in a lens cutting such an extraordinary angle, is corrected by an ingenious device in the form a star diaphragm, which is rotated in front of the lens, by means of a bulb and tube attachment, during the exposure. (they are talking about compressing a rubber air bulb and using the air to spin the star)

The Hypergon is a special lens for wide-angle interiors, landscape, architectural and panoramic pictures, and it should not be purchased with the idea that it can be sued as a lens for general photography.  It cannot be fitted to between-the-lens shutters.

Lens Impression

ゲルツ社のハイパーゴン(ハイペルゴン)レンズは、1900年に考案された「究極の」超広角レンズです。
前後1枚ずつの半球面型の凸メニスカスレンズを向い合せ対称の位置に配置することで、ペッツバール和をほぼゼロとし、単純な構成の超広角であるにも関わらず平坦な像面を実現したています。
しかし、球面収差、色収差などは補正されていませんので、明るい開放値は実現できませんでした。このレンズは開放でf22(stolze絞り48)で、それ以外ではf32(stolze絞り96)しか変化できません。
また周辺の光量が極めて制限されるため、上記写真にあるような風車がレンズの前についており、露出時間(f22/f32ですから当然長時間になる)の大部分をエアポンプで風車を回転させながら撮影して周辺部に光を取り入れ、残りの時間は風車を外して
中央部の露出をするという非常にユニークな仕組みとなっています。
1900年ですから、もちろんこのレンズは大判カメラ用であり、この75mmは8x10が標準です。(60mmのものは5x7判、90mmは10x12インチ判)

今回はこのハイパーゴンにちょっと工夫をして、NEXで使ってしまおうという企みです。
工夫した内容はマル秘ですが、上記写真のように、通常の交換レンズと同じように着脱して使用でき、超広角とまではいきませんが、そこそこの広角でデジタル撮影が可能となりました。
レンズが集めた光は、8x10判ではなく、APS-Cサイズに集まっておりますので、f32の位置で撮影しても、シャッタースピードは結構手持ち可能で切れます。


Goerz Hypergon lens is one of the ultimate Ultra Wide Angle lens designed in 1900.

I tryed to modify my 75mmf22(Stolze number48) Hypergon lens to fit into Sony NEX and successfully completed. 
The way I modified the lens is confidential.
It can be changed as other Sony interchangable lenses and gives me very unique photo description even its angle is not real ultra wide.
Light coming through the front lens is gathered into APS-C size instead of 8x10, so shutter speed when I shoot is not too slow to give up taking pictures without tripod.

Turip & late flowering Cherry
(チューリップと遅咲きの桜)

近くの河川敷公園のツーリップが満開ということで行ったところ、ちょっと盛りは過ぎていました。一方で八重桜はまさに満開で、枝が折れてしまうのではないかと心配になるくらいに牡丹雪のような花をいっぱいに付けていました。
今回はハイパーゴンならではの色再現を強調するため、RAWを現像する際に、コダクローム25のシミュレーションフリーソフトで味付けをしました。かなり色も濃いめに出ているようです。。

Somebody informed that Tulip is already in full bloom near my house and I went to find it was rather a little too late. 
On the other hand, double cherry blossoms were just in the prime time.
I added the taste of Kodachrome using a film simulation free soft to emphasize the color reproduction of this Hypergon lens.. .

Sakura at Shinagawa
(品川の桜)
     

品川海上公園にある桜並木です。規模はとても小さいものですが、一部が桜のトンネルのようになっていて、結構奥行のある画像が撮れました。
改造ハイパーゴンの最初の作例ですので、雰囲気づくりも含めてすこしセピアをかけたB/Wにさせていただきました。
ファンを回さなくても周辺部が暗くなることはありませんが、改造のせいか、少し周辺が流れる感じですね。

Cherry tree line path at Shinagawa Kaijo park. The area is very small but I could take photos with depth because some cherry trees shapes a kind of cherry tunnel. 
I arranged these 1st photos into sepia toned B/W to expose my personal image of hypergon's atomosphere. 
Peripheal area is not dark even without fan operation, but bokeh of the area flows a little .

Sakura at Nakameguro
(中目黒の桜)
   

中目黒エリアにある目黒川沿いの桜並木は、木自体も大きくて迫力十分であるのに加え、水面に向かって下方に伸ばした枝にびっしりと花が付き、まるで日本画のような、とても幻想的な雰囲気も楽しめます。

Cherry tree line at Nkameguro area along Meguro river. Cherry trees there are tall and big enough to feel their power. And I could enjoy cherry blossoms on branch growing downward as a Japanese-style painting which shows such fantastic atmosphere.
