Zuiko AUTO-Zoom 85-250mm f/5.0

Those days, it is not exaggerating to quote Zuiko lense group easily has one of the most comprehensive selection of MF zoom lenses between the 80-250mm mid-tele-zoom range in 35mm SLR photography. To be more exact, it is even quite confusing to see so many lenses with overlapping focal lengths within these zoom range. See a compilation at a chart below:

As illustrated, there are quite a number of Zuiko zooms have overlapping focal length in the Zuiko zoom series.

Naturally, as a consumer, I will not complaint too much as more choices are better for us. However, variation in terms of zoom range and lense speed in these Zuiko zooms can be considered as quite minute in technical specification where I thought Olympus should have consolidated the numbers while saving the resources for other better options such as creating a new lens-type with differing lense spec for users to select. Anyway, as some of these lenses were actually introduced as replacement to phase out and/or as update to older ones at various stages. Well, it is history now but looking back how Zuiko zoom lense series has evolved all these years, you can't stop thinking what should be a better decision. Well, when the OM-3Ti was eventually debuted in mid-90, strangely, the only Zuiko zoom that was being highlighted in the camera's sales brochure was just a Zuiko AUTO zoom 35-80mm f/2.8 ED.

The Zuiko AUTO zoom 85-250mm f/5.0 was probably introduced during the first quarter of the '80. It provides a practical zoom ratio of approx. 2.9X and effectively ranked itself among the best in zoom range in its class. At the time, other than its maximum aperture, I thought this zoom was quite amazing in its extended zoom range which provides such a long reaching 250mm at its telephoto end, while other manufacturers were only contented to opt for a normal 200 or 210mm setting. The zoom range covers one of the most frequently used focal lengths in tele-photography which makes it an ideal traveling companion zoom lense for landscape, scenic, candids, portraiture or other general photography. With smart selection of fast film types and/or if lighting is favourable, it can even be a good choice using in professional applications such as sports, news and photojournalism.

With a indicative retailed price (used) between USD225.00-USD300.00* - this lense presents great value in its versatility and flexibility. The lense has well thought out features that only be found in more luxurious class zoom lenses. (even the subsequent equivalent, one-touch Zuiko AUTO-zoom 50-250mm f/5.0 lense has this lovely feature removed) where In particular - I like the incorporation of a tripod collar built at the rear section of the lense as it equalizes the weight distribution of this rather heavy lense away from stressing the camera's lense mount. *Source: MacBroom's Camera Blue Book.

The solidly built lense uses a larger filter attachment size of 55mm but it also provides a built-in lense hood which has a rather long extension which effectively provides good shades and eliminates the need of storing and carrying an extra lense accessory. Overall, the lense handling is excellent despite with its relatively long dimension and considerably weight it has.
