The following opinions have been automatically translated with Microsoft Translator. | Olympus OM Zuiko 85mm f/2 Pros: Size, excellent mechanical dial soft focus and fluid filters from 49 optical yield very uniform Cons: Currently a disability can be considered the manual focus Opinion: I found a review in an old issue of "The Photographer" with the attached diagram risolvenza that says "... once again we are faced with a remarkable lens for uniformity of performance at all apertures and all over the field. The performance continues to progress up to f11, where it stabilizes and does not show even the slightest drop to minimum aperture. mitigated by the enthusiasm we think that the resolving power at wide apertures is small, barely acceptable at 5.6 and only really satisfactory f8 onwards. Excellent instead distortion, of which few traces remain barely perceptible pincushion .... "Nevertheless, I bought it at the time, and it was one of my favorites length: ideal for portraits, I got used to the whole opening ever images with excellent contrast and colors. I think it is to carefully reconsider its use in digital, especially with the APS-C format, to get a tele f 2 with brightness! sent on March 18, 2014 |
 | Olympus Zuiko 21 f/3.5 Pros: size and weight, 49 mm filters, optical performance. Cons: Exceptional "only" f 8 and up. Opinion: I found a review in "The Photographer" many years ago, with the attached diagram risolvenza that says ".... also in terms of performance this tiny fisheye can be considered one of the finest examples of its kind. Exceptionally good early as f from 5.6 up to 2/3 of the field, only the extreme angles leave something 'to be desired at wide apertures but improve with decision af 8 eaf 11, where you will reach the maximum efficiency and a remarkable uniformity throughout the frame. ... "rnrnDa remember that this lens protrudes only 3 inches and weighs 180 grams, with filters of 49 mm! It 'was the lens I used more, whatever the occasion. rnMi is inevitable to think that today, to have the same angle of view on an APS-C camera, I have the dimensions and weight of a 14 or a zoom lens Samyang 10 -20, so it seems a big step back. sent on November 11, 2013 |
 | Olympus 50mm f/1.8 OM F.Zuiko Pros: Minimum size and weight, from 49 filters, excellent overall yield Cons: Little delicate in tonal passages Opinion: The manufacturer says. "Extremely compact and its optical design provides a superb definition for sharp images across the entire frame, with an appreciable reduction of internal reflections." . In fact it is 5 mm shorter and 60 grams lighter than the already small 50 f1, 4. When these parameters were crucial, I preferred it to f1, 4, but did not get the same answer delicate gradation in total. Great in macro, thanks to its optical design symmetrical. sent on May 17, 2013 |
 | Olympus OM Zuiko 50mm f/1.4 Pros: Size, excellent mechanics, ring soft focus and fluid, filters 49, optical yield very uniform Cons: Soft to f1, 4, (but acceptable given the brightness) Opinion: I found a review in March 1993 with pictures attached diagram risolvenza that says ".. a normal race, very bright, that certainly did not fit between the cost optical. A confirmation of the excellent results that can be expected from standard optics, and if the weak point are internal reflections they are justified by the large maximum aperture. " The behavior is classic, or the yield is very uniform across the central, middle and peripheral growing risolvenza with the closure of the diaphragm. RnPersonalmente, I appreciated the ability to reproduce even the most subtle tonal passages, and, using it wide open, to maintain a good contrast. rnL'esemplare in my possession has a nice amber color of the outer covering of the front lens, which I have not found on other objectives of serie.rnDa carefully reconsider its use in digital, especially with the APS-C format, to get a tele with brightness f1, 4! rnrn sent on May 17, 2013 |
 | Olympus OM-2 Pros: Size, strength, perfect exposures in low-light conditions even with long exposures, convenient switch automatic / manual, silent and vibration-free, along with body / lens very balanced Cons: Electronic Shutter dependent on batteries, viewfinder with 97% field of view Opinion: The model OM2, appeared in 1974, while presenting a body similar to the OM1, was truly revolutionary: automatic exposure cameras were already in existence but now the exposure was assessed in "real time", ie while the picture was taken. Through two silicon cells, the camera measures the exposure while the film is impressive, taking into account only the actual light that reaches the film. Thanks to the speed of the reaction of cells to measure, was developed the first electronic flasher system which used the same cells for adjusting the duration of the flash, thus working in full automation, in direct or indirect light, with bellows, extension tubes, filters, with all the sensitivity of the film. rnPersonalmente I found great use in low light, shutter speeds than 1 sec. , Even of a few minutes, obtaining exposures impeccabili.rn The model OM2 Spot / Programm, represented the maximum evolution: included the possibility of measuring exposedsimetrica spot and, placing the ring on the lens iris control value closed, the use of a program that the couple chose shutter speed / aperture. It was a successful model, presenting problems for electrical circuits. Rn sent on May 17, 2013 |
 | Olympus OM-1 Pros: Size, strength, mechanical shutter, convenient switch the exposure resulting in long battery life, quiet and vibration-free, along with body / lens very balanced Cons: Viewfinder with 97% field of view Opinion: When the OM1 was presented at Photokina 1972, the designers gained against the Olympus cameras of the time do not grams and millimeters but ounces and inches, offering a complete system, including lenses and accessories all consistent with the philosophy behind the project, ie all small. The camera possessed interchangeable focusing screens, electric motors drive, the park fisheye lenses ranged from 8 mm to 16 mm to 1000 mm telephoto, passing through the entire zoom range, with some truly incredible achievements for compactness and performance (such as 21 mm f3, 5 and 35 mm f 2.8 decentrable). rnHo bought in 1974 one of the first models (to mount the engine had to be done in support), I brought the camera everywhere, in deserts as on the snow 5000 m above sea level, making thousands of rolls and I always brought home pictures. Only in 2008 (!) I did a general overhaul, changing the electrical power supply system for the 1.5 V batteries. RnAncora today I bring with me, if, whatever happens, I want to be sure to bringback image rn sent on May 17, 2013 |
