S-Zuiko AUTO-Zoom
100-200mm f/5.0
With a zoom range that spans
from 100-200mm, a 2X zoom ratio with a slow effective aperture of f/5.0, it may easily
lead you to believe that this is not an high end kind of optic. Well, it wasn't,
although I wouldn't simply classify it as "economy lenses"#
as with most OM users do because it does has its own market and specific group of
target audience. This lense was primarily being designed to serve users with different
kind of working budget and applications such as for students, casual weekend photographers
and/or those who likes to travel light in outdoor events such as mountain climbing,
tracking, scenic, landscapes and other kinds of general photography. Well, for the
smart ones, if you bundle this lense with another popular 28-48mm Zuiko zoom,
that is all you will ever need to fulfill most of your photographic needs covering
from wideangle to telephotography.

This unusually compact zoom (148mm long and weighing 570g) covers the picture areas of separate 100mm, 135mm, 180mm and 200mm medium telephoto lenses. It features a one-touch focus/ zoom control to enhance easy and smooth picture composition, enabling the photographer to respond to quick actions without missing important shots. The only technical aspect you need to take note is, unless the lighting is favourable, it is always encouraged to use this lense along with a faster film types (such as ASA/ISO 200 or 400) to compensate for the lack in maximum lense speed. |
# Many OM users firmly believe a handful of Zuiko lenses in particular those which carry a "S" letter in front of Zuiko are designed specifically for budget users and termed them as economy series. Other Zuikos that carry with such inscription are S-Zuiko AUTO zoom 28-48mm f/4.0, S-Zuiko AUTO zoom 35-70mm f/4.0, S-Zuiko AUTO zoom 35-70mm f/3.5 ~ f/4.5 and S-Zuiko AUTO zoom 70-210mm f/4.5~f/5.6.
Next, Olympus actually advises in its user's manual that " .... it is necessary to confirm through the viewfinder that the subject is in focus after each zooming. The zooming/ focusing tube is designed to stop at a point off the index line to allow for precise focusing....". which means two things, first, despite the lense has a constant aperture of f/5.0, there may have a tendency in focus shift where refocusing after zooming is always encouraged. Next, the restrictive maximum aperture may also present some degree of focusing problem as the viewfinder may get dim while the split-rangefinder usually may get darken and you can only make use of a right choice of focusing types helps to improve/ensure ease in focusing. Olympus has suggested 1-1, 1-4, 1-6, 1-10, 1-13 and 1-14 where 1-6 microprism-clear field was in particular useful but depends on applicable OM bodies**, performance and/or comfort level may varies. This zoom lense can stop-down to a minimum aperture of f/32, this can be used for extended depth of field control when used in combination with compression of perspective which starts to be quite apparent at its longest zoom setting.

Another interesting feature which relates to this lense is, this is one of the two* Zuiko zoom lenses that actually has Olympus stating officially that it is compatible with the 2X-A Teleconverter. In this case, if such combination is used, it will transform the lense into a possible 200-400mm f/10 super tele-zoom ! Well, although I doubt very much who would use in such a way as the effective working aperture of f/10 is simply hard to find suitable subject and condition to shoot with while on the other hand, as this zoom lense by itself only may cost ranging from USD70.00 -USD150.00** a unit (in mint, used condition) while a comparing Teleconverter may cost higher than the working lense ! Obviously, although I would love to think such "announcement" is workable and exciting but conventional wisdom may tell you it doesn't make any sense to call for such kind of additional investment other than you have already own a tele-extender in your personal collection. * Another unit is the Zuiko AUTO zoom 50-250mm f/5.0 MACRO ** Source: MacBroom's Camera Blue Book.

Anyway, other than providing good factors in its compactness, lightweight and a moderate zoom range it can offer, this Zuiko zoom does have some delightful touch, firstly, it is being multicoated for faithful colour rendition, minimizing chances of ghosts and flare when used in unfavorable shooting situation such as shooting in a backlit scene; next, the one touch zoom does conformed to OM standard with its reasonably well built quality and lastly, it is easily ranks as the most affordable zoom lense supplies under a major manufacturer's label. Come to think of it, this Zuiko lense can easily be transformed into a 3X zoom such as 100-300mm but I am still puzzled why Olympus never did that where I think such possible zoom range should appealing to a larger group of users. |
