As you step up focal length of your lenses to 135mm, you will notice an increase in compression of perspective, narrowing angle of view, an increase magnification of image size and a decrease in depth of field. Effect of distortion begins to decrease and perspective is more natural makes them in particular handy for portraiture at closer range, for an example, head and shoulder types of photography. Besides, the extra working range ensure the model you are shooting can be more relax and comfortable otherwise may result in tensed facial expression. Naturally, you can find plenty of other good applications for this lense and they are not solely confined only for portraiture. These lenses are often used in candid, sports, scenic, nature and photojournalism. The tighter angular field of view at 18° is good for isolating and/or emphasizing an interesting area especially in scenic or in travel photography. When you combine this with compression of perspective, another optical characteristic found in telephoto lenses, you can create many interesting, attractive and powerful visual.

However, lenses at 135mm can be considered as a medium range tele-lense within the telephoto group and they will project these unique optical effects in a middle-of-the-road way while not overpowering them. These lenses are designed to be easy to use and handle and usually they are equipped with a good usable lense speed to make them an all round optic for available light photography. The Zuiko lense family does not provides a fast speed 135mm f/2.0 version but there are two alternatives with a moderately fast lens speed, E-Zuiko AUTO-T 135mm f/2.8 and a slower E-Zuiko AUTO-T 135mm f/3.5 lense for consideration. Actually, there is also a special application close-focus Zuiko AUTO MACRO 135mm f/4.5 lense, which requires either using an AUTO Bellow Unit and/or the OM Telescopic Auto Tube's focusing mechanism to adjust focus (it can only provide fine focusing on its own). The two normal ZUIKO telephoto lenses are designed and made extremely compact and portable. Optically, both have remained unchanged in their optical formulas since the days of introduction except in the case of lense coating process and/or minor cosmetic changes that may have been improved over the years. The last of version for the Zuiko AUTO-T 135mm f/2.8 carries a "MC" designation in the lens data which began shipping back in 1977/8 while the Zuiko AUTO-T 135mm f/3.5 has such update started probably between 1983/1984.

* MORE info..... It is such a sad state to notice Olympus has taken off these two lenses from their product catalogue as early as '90. Naturally, that was a commercial decision with shrinking sales of SLR cameras and in particular, fixed focal length lenses and by year 2002/3 the Company finally discontinuation of the GREAT film based 35mm SLR OM system.
In terms of angle of view, 85mm is about 10° greater in angle of view than the 135mm lense, while lenses at 135mm has 10° more angle of view than the 300mm. As we noted earlier, the subject area of the 135mm is about 25 percent of the area covered by the 85mm lense and about four times that of the 300mm.

E-Zuiko AUTO-T 135mm f/2.8 & Zuiko AUTO-T 135mm f/2.8

This focal length is often considered the first true telephoto. It achieves very noticeable depth of field effects. Olympus has two 135mm telephoto lenses ever since the very early OM system was introduced. Although it shares many common features with the slower Zuiko counterpart of E-Zuiko 135mm f/3.5, the E-Zuiko 135mm f/2.8 which has a faster lense speed, a fine performance and easy handling has made it a favorite first telephoto lense among the many OM photographers all these years.

Other than cosmetic differences it may has, the older version and newer ones share a similar optical formula with their 5 elements in 5 groups design. To cater for a more demanding light gathering power at f/2.8, this Zuiko lense has a considerably larger filter attachment size at 55mm instead of the OM standard 49mm filter thread. The minimum f-stop fro this lense is f/22 which is useful for maximum depth of field control, inparticularly when you intend to maximize its unique compression of perspective control. With a telephoto ratio of 0.88 - its body length measures at 80mm, focuses down to minimum distance of 1.5m (4.9 ft) and weighs 360g (12.7oz). Designed for maximum handling ease with a good compromise ratio between practical speed and affordability which has make this lense a highly desirable telephoto lense. An added advantage is, it was equipped with a built-in retractable telescopic-type of lense hood which eliminates the need of carrying an extra filter accessory. With a compatibleTele-converter such as 2X-A , this lense may be able to extend as a 270mm f/5.6 lense.
