Zuiko AUTO-Zoom 35-80mm f/2.8 ED

You are looking at probably one of the best ZUIKO zoom lense you can find in the Zuiko lense system. It was a late inclusion as it was originally introduced as an limited edition optic bundled with the classic Olympus OM3Ti SLR camera. When all is said and done where sometimes, ultimate creative decision also lies in your smart choice of lense for your photography, with the OM system Zuiko interchangeable lense group, you can choose from a wide lineup of precision lenses while this remarkable Zuiko master piece is one rarity that stands up among the rest. It provides a constant-aperture f/2.8 across the entire zoom range from 35~80mm and sets a new standard of optical precision in zoom lense design. By using both Extra Low Dispersion glass and High Refractive Index glass lenses, OM optical engineers were able to develop a zoom that rivals many s of the single focal length lenses in its ability to capture the main subject with sharpness and clarity in exceptional optical quality, while on the other hand, the large aperture provides gently blurring background and foreground for maximum creative effect.

Prior to availability of this lense, there were already five wide to tele Zuiko zooms within the Zuiko lense group (Zuiko AUTO Zoom 35-70mm f/3.6, S.Zuiko AUTO Zoom 35-70mm f/4.0, Zuiko AF AUTO Zoom 35-70mm f/4.0, Zuiko AUTO Zoom 35-105mm f/3.5-f/4.5 and two entry level zooms, S.Zuiko AUTO Zoom 35-70mm f/3.5~f/4.5, S.Zuiko AUTO Zoom 35-70mm f/3.5~f/4.8 along with a sole wideangle zoom in Zuiko AUTO Zoom 28-48mm f/4.0. As you can notice from the directories, all available Zuiko options are rather slow in their workable opening lense speed. So, the introduction of this fast speed Zuiko zoom has truly expanded the functionality of the zoom lense group. But strangely, in an OM-3Ti sales catalogue published back in mid-90, it only stated this zoom in the Zuiko lense sales reference guide.

This high speed wide-to-tele vario Zuiko lense provides a rare glimpse of the optical construction illustrated in the camera's marketing brochure - a move seen as highly unusual, but it indicates how much pride those optical designers has in the realization of successful design in this remarkable zoom.

The selection of the midrange zoom range from 35-80mm, although was still regarded as conservative if measures by prevailing zoom lense development at the time but I think Olympus has calculated all aspect in terms of practicality and affordability before a decision was made. Somehow, the Company must have felt priority should be given to performance and portability rather than a lens-spec that shines only in exotic zoom range which may otherwise adds more complication to the design of a workable zoom lense (such as weight, price factor and difficulties in overcoming other optical aberrations). As of now, this Zuiko zoom has a suggested listed price between USD1150.00-USD1200.00* - it is not considered as entirely cheap for a MF zoom but could be worst if it has been designed as a more exotic 28-135mm f/2.8 ED, huh ? Well, seeing its complexity in its optical design and high built quality it presents, it seems every pennies is worth while right ? *Source: MacBroom's Camera Blue Book.

Lense handling is excellent, other than the generous extension of the focusing grip which facilitates slip-free, positive focusing action, the lense provides with all other essential picture taking information that is well illustrated and clearly outlined for easy shooting reference. The zoom control ring has been expanded and has three zoom settings of 35mm, 50mm, 80mm printed in a bright green on the zoom lens tube to provide visual aid for easy reference. The two infrared indexes may shift as you zoom where two orange focal lengths indexes for 35mm and 80mm are located just next to the distance index as reminder.

Optically, this remarkable vario-Zuiko lense has clearly benefited from the extensive use of rare-earth glass in its optical design, as its excellent optical performance is one of the main reasons why it is so appealing to so many serious OM photographers. I have heard many good users' feedbacks in relation to its optical quality and equally convinced seeing exceptional clarity and rich colour exhibits in plenty of high quality images taken with this Zuiko zoom.

Physically, this lense weighs considerably at lense 650g (22.9 oz), probably due to the use of many (16) lense elements and it has a larger filter attachment size at 62mm. Although considered odd for an OM Zuiko lense but since 62mm is still considered as a popular filter size and lense accessories are readily available everywhere. However, Olympus has designed an optional rubberized lense hood specifically for this lense and advises the use of the newer series if focusing screen types such as 2-4, 2-13 and 1-4N for shooting although many of the older screens may also be used (see spec-section below for cross reference). Lastly, Olympus never indicates any compatible Teleconverter for this lense.

Recommended Focusing Screens: 2-4*, 2-13*,1-1*, 1-2*, 1-3*, 1-4N*, 1-6#, 1-10*, 1-13* and 1-14*. * Compatible. #Can be used. They will provide for accurate and easy focusing but meter built into the OM-1 and OM-2 (on MANUAL) will not indicate correct light readings. With the OM-2 on AUTO, correct exposures are made on the film, but the meter needle does not give correct light readings.
