Zuiko Short telephoto lenses

Generally speaking, lenses having a focal length longer than that of a standard lense are called telephotos. They fall into two categories: first, those of the "long focus" variety, with constructions similar to those of standard lenses. With telephotos of this nature, focal length is measured from the second nodal point of the lense to the film plane with the focus set at infinity, The second type of telephoto is the "short barrel" or "telephoto" variety where the distance from the front vertex to the focus of the lense is much shorter than its actual focal length. All ZUIKO telephoto lenses are of the "short barrel" type and are extremely lightweight and compact. Among telephotos, the 85mm lense has become widely known as an ideal lense for portraits and still life photography because it provides moderate perspective with negligible distortion. Because this lense has a maximum aperture of f/2.0, the photographer can take full advantage of the extremely shallow depth-of-field and use it creatively to produce pleasing out-of-focus backgrounds or foregrounds.

In addition to the many innovative optical and mechanical designs incorporated into OM-System ZUIKO lenses, Olympus engineers have made great strides in reducing the overall size of telephoto lenses. For example, the ZUIKO 100mm and 135mm lenses have been reduced to the size of conventional standard lenses, These ultra-compact telephoto lense designs enable the photographer to take handheld photographs at slower shutter speeds. There is a wide variety of ZUIKO telephoto lenses in the Olympus OM-System allowing the photographer to choose a lense to match each and every photographic situation.

West Temple Reflection in Pine Creek, Zion National Park, Utah

" ... Pine Creek is a very popular spot for photographers in Zion National Park. I say that because it took about ten minutes before my field of view in this photograph cleared of other photographers. On another location farther up the creek, I was nearly overrun by a group of about 15 view camera photographers on a workshop.

I metered off the light portion of the mountain, set it at a +1 tone, and bracketed about 1/2 stop up and down. I used a graduated ND filter to maintain detail in the foreground..."

Olympus provides a couple of medium telephoto lenses which offer varying degree of functions and objective to serve photographers to fulfill their photographic requirements. The short telephoto series starts off with a Zuiko 85mm f/2.0 which is a good lense for all round day to day photographic needs. There is TWO special application lenses with almost similar focal length Zuiko 1:1 MACRO 80mm f/4.0 which uses only in conjunction with OM Auto Bellow unit and/or extension tubes (OM Telescopic Auto Tube) and another Zuiko AUTO MACRO 90mm f/2.0 which has helical focusing fucuing from infinity to 1:2 half life size at its closest working distance, where BOTH of these lenses are dedicated for macrophotography. It is quite a popular macro lense as it offers a life size (1:1) reproduction. A late inclusion with similar function was a high speed Zuiko Macro 90mm f/2.0 which can use as a normal short telephoto lense. Lenses with 85 & 90mm focal length bridges the gap between standard and telephoto lenses. Its moderate 29° (27° for the 90mm lense) angle of view isn't substantially narrower but is good for covering wide variety of photographic subjects.

As compared with other ZUIKO lenses at shorter focal length, effect of compressed perspective and distortion are at its minimum level with these lenses, making them a good choice for shooting portraits at a reasonably distance such as half length portrait. The relatively large aperture of f/2.0 of both 85mm lense and the Macro 90mm lense provide two distinctive advantages - firstly, the viewfinder image remains constantly bright which is more comfortable to use for pinpoint critical focusing and/or picture viewing; next, their moderately fast lense speed permits a greater level of depth of field control during shooting.

UPDATE: - The fastest lens speed of the Manual Focus Zuiko telephoto at 85mm in regular production was the known 85mm f/2.0. Macro Cavina from Italy has reported a prototype Manual Focus Olympus Zuiko 85mm f/1.4.

Olympus manual focus high speed Zuiko telephoto 85mm f/1.4
"... The Olympus OM Zuiko 85mm f/1,4 was presented at the 1989 Olympus Technology Fair, and summarizes the state-of-the art in lens making, showing a wide diameter calcium fluoride lens, a special graded refractive index lens (nickmaned GRIN) and a gourgeous twin floating system for inner focusing: a tour de force never seen before in the commercial medium-telephoto range! Rumors whisper about a small run of 50 pieces, enough to declare this lens a real world item and not only a chimaera fluttering in someone's dreams.... Just right here, for the very first time, you'll find the section drawings, the optical and glass specs and the aberrations diagrams at various focus points of the 13 (SIC) prototype options of this mervellous lens, an huge contribution founded on the careful parsing of the very complex original project by Aoki-San...".

Although the lens has remained as a protoype, but still, it was a Zuiko. You can go to Marco Cavina's site on this highly recommended article who also exhibited some of the optical analysis of the rarely known Zuiko 85mm f/1.4 faste speed telephoto. It was written in Italian but you can make use of Google utility to translate: http://google

F-Zuiko AUTO-T 85mm f/2.0 & Zuiko Auto-T 85mm f/2.0

The first focal length to give distinct telephoto effects, this 85mm lens is extra fast, yet as small as many standard lenses. This lense produces images 1.5 times as large as those of a standard lense yet is almost the same size (
telephoto ratio 1.06) as conventional standard lenses. It produces photographs with a natural perspective making it ideal for portrait, travel and still life and/or studio photography. A built-in automatic correction mechanism compensates for aberrations at close focusing distances. The fast f/2.0 lens speed and inherent shallow depth of field is extremely useful for creating pleasing out-of-focus foregrounds and backgrounds in portrait photography. it is a perfect lense for low light situations such as interiors and night scenes and the fast speed enables the photographer to focus quickly and easily.

The 85mm, in particular has long been given a lot of emphasis as an ideal focal length for portraiture. Thus stress was placed on enhancing this lens' full aperture and close focus capabilities. This lense maintains its high optical quality even at its closest focusing distance of 0.85 meter because it used to be the only telephoto lens within the Zuiko lens family that incorporated with a close-range optical correction mechanism to counter aberrations. The older version has a different optical construction of 6 elements in 4 groups while the revised version is employing a 5 elements in 4 group design; however, BOTH versions are incorporated with automatic correction mechanism against close distance aberrations. The new Zuiko lense, despite has a element lesser than the predecessor, maintains its weight equivalent to the older version. A general way for identification for both versions is, the newer version has omitted the "F-ZUIKO" and simply mentioned it as ZUIKO AUTO-T 85mm f/2.0.

Just to show you how compact this fast speed ZUIKO telephoto lense is, despite It comes with a f/2.0 maximum aperture, it still be able to use any OM-standard 49mm threaded filter accessories. Lastly, Olympus has only a sole lense offers at this focal length but it serves well with its good lense speed, highly portable dimension and weight, making it one of the most desirable telephoto lense in the ZUIKO lens family. This Zuiko telephoto lense retails between USD370.00**-420 a unit (new) and even at used, mint condition, a reasonable indicative price between USD235.00-00 - 250.00 a unit are not uncommon.
