E-Zuiko Auto-T 100mm f/2.8 & Zuiko AUTO-T 100mm f/2.8
Although its focal length is twice as long, this 100mm lense is approximately having the same size (telephoto ratio: 0.93) and weight almost comparable to a conventional standard 50mm lense. However, because of its 24° angle of view, it produces images twice as large. It has been designed to deliver similar high resolution and contrast as a 50mm ZUIKO standard lense but it provides a more natural perspective which makes it such an ideal lense for half-body length portraiture photography. Naturally, it can be used in a wide varieties of application such as travel, scenic, candid as well as fan excellent lense for indoor studio shots.
It is an excellent lense for isolating detail such as using it in nature or scenic photography. Photo data: OM-4 w/ZUIKO Auto-T 100mm f/2.8

The ZUIKO lense family has two known versions introduced thus far for the ZUIKO AUTO-T 100mm f/2.8 - but difference is mainly confined to lens coating used and minor cosmetic changes but not optically. The original version debuted along with the OM system back at the early seventies has a very simple, straight forward optical construction of 5 elements in 5 groups and the optical formula has literally unaltered all these years. Those very early version may carry a silver-chrome filter rim (or popularly referred as "silver-nose") while subsequent followed up version has it all in plain matte-black finish. Some of these early lenses may not have been multi-layers coated where some seasoned OM users think those with the lense designation "E-Zuiko" may or may not have been multicoated. Another general way for such identification is whether the lense have an indicative "MC" word added to the lens data to distinguish both groups. Well, as there is no conclusive ways for easy identification provided thus far, some users even use the reflectance of colour on the front lense element help to identify the difference of versions. Generally, as most ZUIKO lenses produced after 1982 may have "MC" imprinted along with other essential data which by far is the most accurate way of guessing. Anyway, I am not an OM expert and if it matters a lot to you, a good way is to make of of other online resources help for such identification.

As compared to the more glamour Zuiko equivalent of Zuiko AUTO-T 100mm f/2.0 ED, this compact zuiko lense is a more popular optic because it has a more realistic, affordable entry price than the earliar mentioned high speed Zuiko. Although this zuiko telephoto comes with a f-stop slower in its maximum lense speed, but I would rather think it offers a better value. This highly portable telephoto combines many excellent features such as compactness and lightweight with a top class image quality it delivers - Image rendition is uniformly excellent at all subject distances and aberrations are well kept under minimal level for superb image quality across its entire focusing range.
Measures at merely 48mm in length, balancing and handling for this lense with any OM bodies attached onto it is make it such a joy to use. The frame-filling 24° angle of view provides pleasing perspective where subjects are small and have a lot of details. The 100mm focal length is also a good snapshot lense because it allows the photographer to keep a comfortable distance between himself and the subject in order to retain the natural facial expression while the f/2.8 maximum aperture, other than providing a for variable creative depth of field control and should provide a good shooting experience for those who always believe investing into a slow speed zoom lenses all these while. With a compatibleTele-converter such as 2X-A , this lense may be able to extend as a 200mm f/5.6 lense.
Overall, the 100mm is a good focal length provides virtually endless versatility in photographic applications such as multitude of subjects - sports, scenic, nature, people and photojournalism. This high performance Zuiko AUTO-T 100mm f/2.8 offers photographers an excellent alternative to the fanciful but features-rich f/2.0 Zuiko equivalent if cost is a primary factor for consideration.
