Because the first-generation summicron 90mm lens was too large and sales were not good, Walter Mandler took the pride in designing the second-generation summicron 90mm f / 2, which is great. The optical design remained unchanged from 1980 to 1998. Many people still like it so far, more than the latest 90mm apo asph version.
The second-generation summicron 90mm f / 2 e55 is very numerous and affordable. The E55 version looks very beautiful. It is almost the same size as 90AA but lighter than AA. It is capable of taking portraits, landscapes, etc.
The first-generation summicron 90mm f / 2 is very good, but it is really too large. For Leica M, the lens size is very important.
90mm f / 2 E55 weighs 475 grams;
50mm f / 1.4 silver version weighs 460 grams;
50mm f / 1.2 weight 470 grams;
90mm f2 ASPH / APO weight 500 grams;
90mm f / 2 large head nine weighs 685 grams;
50mm f / 1 E60 weight 630 grams;
50mm f / 0.95 weight 700 grams;
75mm f1.4 weight 760 grams;
Between the ideal and reality of photography, it is a mountain of cameras and lenses that is insurmountable. A few people crossed the mountains, and most were lost in the valley … 90mm is a mountain peak of the lens, which is difficult to conquer?
The 90mm field of view is smaller and more focused than the 50mm field, it pulls the focus away from the environment. So 90mm is often used for portraits and partial close-ups, but some people like Saul Leiter use 90mm street to shoot. The elegant urban light and shadow makes my eyes wide open. So I’m going to climb this peak.
- Usually locked to 5 meters. First estimate the distance between the subject and yourself, generally 10 meters away and 2 meters closer. Increasing or decreasing from 5 meters can shorten the focusing time.
- Use Leica M3. The M3 has a magnification of 0.91 and a large focusing screen.
- Focus on the reference object in advance. When the person reaches that position, press the shutter.
Do not shoot blindly. The depth of field of the 90mm lens is too shallow. Blind shooting is tantamount to wasting film.contact: firstname.lastname@example.org © 2020 Zhao Zhenguo. All Rights Reserved.
