Re: [分享] minox 35 GL陽光下隨拍

Minox這台上面好像沒有特別標明?
印象中Rollei 35 SE用的是Sonnar,35 TE用的是Tessar!

35mm, f/2.8, Minox Color-Minotar (4 element Tessar type)
Martin Tai , dec 25, 1998; 02:14 a.m.
Minotar and Minoxar are Tessar type four elements three group design. 35mm/F2.8 Minotar is used in Minox 35ML and other Minox 35mm cameras; Minoxar 35mm/F2.8 lens is a better lens, it focused closer to 70 cm (2.3' ) vs 90 cm (3 feet) of Minotar. Minotar or Minoxar lens is focused by turning a high power front element. Front element focusing is common in many cameras with Tessar lens, such as Rollei 35, Zeiss Ikon Contessa etc. Since the front element of a Tessar type lens has three times the power of whole lens, the focusing movement required is only 1/9 of unit focusing, this is evident from Minoxar/Minotar, the front element movement is about 1 mm, very small.
Minoxar and Minoctar lenses are the only sucessful wide angle Tessar type 4 element lens.
There are other 35mm/f2.8 lens but they could not achieve with as few element For example, Nikon 35mm/2.8 had to use 5 elements Olympus XA Zuiko had to use 6 elements for 35mm/F2.8 ( quite a bit of flare and not as sharp ) Not even Carl Zeiss, they need to use 6 elements for the Distagon 35mm/f2.8 lens for Contax SLR. Minoxar/Minoctar is the king of wide anngle Tessar type lens
When I photograph architecture subjects, I always amaze at the almost unnoticeable distortion of Minoctar/Minoxar lens. A column is amazingly ruler straight. I know, because my 50mm/f2.8 Carl Zeiss Tessar lens, even though it is not a wide angle lens, should be easier to design, yet it has slight pincushion distortion. I have an expensive 6 element F2.8 lens, yet it has visible barrel distortion ! While the 4 element Minoxar gives me straight columns !
Minoctar/Minoxar lens is absolutely amazing Who ever designed the Minoctar/Minoxar was an optics wizard.
最後,我只能說百年老鏡Tessar真是銘鏡啊
Happy 100th Birthday Tessar !
