F-Zuiko AUTO-T 200mm f/5.0

The F-Zuiko AUTO-T 200mm f/5.0 weighs only 380g; it uses an optical design comprises of 6 elements in 5 groups, with a body length measuring merely 105mm in length and an overall diameter of just 62mm - it is barely larger than a Zuiko AUTO-T 100mm f/2.8 or Zuiko AUTO-T 135mm f/3.5, making it easily one of the most compact Zuiko telephoto in the Zuiko lense family.

Except for the differing maximum lens speed, this ultra-compact Zuiko tele-lense shares many basic features with the faster counterpart which includes a useful minimum aperture that can stopped down to f/32 and a minimum focusing distance at 2.5m (8.2 ft). One of the plus point it has over the Zuiko AUTO-T 200mm f/4.0 is its filter thread which is 49mm OM standard and enables it to share with many other OM filter accessories that you may have in your own system. However, the biggest attraction of this lense is still its modest entry price which is highly affordable even to beginners such as students or those who may be cost conscious but still insists on sticking to a OM quality optic. As a comparison, a new 200mm f/5.0 lense those days may fetch at only USD200.00* a unit as compared with the f/4.0's USD300.00. Naturally, both of these Zuiko tele-lenses are more attractive when comparing with the fast speed Zuiko AUTO-T 180mm f/2.8 which retails between USD700.00 -USD880.00 a piece ! *Source: MacBroom's Camera Blue Book.

Frankly, these indicative pricing may also turn away some users to look at alternatives in a versatile zoom lense which may offer a faster lense speed, in particular those offer by third party labels. In fact, I suspect this could also be one of the reasons why Olympus has decided to let this Zuiko lense retired from service. Well, on a practical note, if the lens speed is a primary concern, you can always offset this negative element by using a faster film type to compensate it. Anyway, information as well as images (esp. older ones) for this lense is hard to source and I have to pen-off here to see if I can gather more content and beef up the content in this section here later.

OFF TOPIC SUPPLEMENT when handling a telephoto lense

The depth of field of the 180-200mm is comparatively limited at any aperture as compared with lenses having shorter angle-of-views. At maximum aperture depth of field is extremely shallow and may require precise focusing.

The range of sharp focus increases, of course, as camera-to-subject distance increases and as you select smaller apertures. With lenses of these focal lengths, perspective often works best when the foreground and background are as sharp as possible. Maximize the benefit and the unique optical characteristic of telephoto lenses such as compression effect by using small apertures whenever possible to increase depth of field. This works best if there are subjects of similar patterns.

On the other hand, it is easy to render out of focus unwanted background and foreground images to emphasize the main subject or to play down distracting elements at the background inside a picture. The larger the aperture, the more effective this technique. The fast speed Zuiko lenses at 180mm focal length provide the best solution to portraiture with such visual effect, focal length of 200mm with the maximum aperture limiting to f/4.0 may not be the best option but still provides a fairly good effect for a reasonably blur effect in front and behind the subject in full length portraits. But other than full length portrait, the f/4.0 and even the f/5.0 is more than good enough for a head and shoulder or half length portraiture. Another good use of these lenses is its ability to isolate a small portion and magnify on how we visualize a full vision with human eyes - this is especially useful for scenic shots where you can train your eyes to isolate an interesting portion of the scene.
