A brief overview on Zuiko 35-70mm zoom lenses

The first zoom lense with a practical 35-70mm wide to tele focal length was a Canon's FD 35-70m f/2.8-f/3.5 which first brought to the photographic world back in December, 1973. Over the years, the growing popularity and improved performance in zoom lense design has lead many manufacturers toying with the idea of using such zoom lense to replace conventional standard lenses which usually bundled with a new purchase of a SLR camera. The first successful mass application of such marketing theory was again pioneered by Canon which has their second generation T-Series body, Canon T50 (1983) sold along with a redesigned all-polycarbonated FD 35-70mm f/3.5-f/4.5 zoom, weighs merely 210g (7.4oz.) - which is even lighter than a conventional standard 50mm f/1.4 lense ! Today, 35-70mm zoom lenses are often called standard zoom. Although measures by modern standard, any of such typical 35-70mm zoom falls short of everything except in price in particular those with variable apertures - they have been designed even smaller and lighter.

Kids on candid...
One of the main advantage offers in any typical zoom lense is framing flexibility. The angle of view increases and perspective becomes increasingly stretched out when zooming back from the standard 50mm focal length towards the 35mm end. As you zoom from the 50 mm setting to the 70mm extremity, you will notice that blurs, rather than compressed perspective, become increasingly conspicuous. Zooming capability thus permits optimal framing, plus the choice of elongated or compressed perspective to suit the subject. It is versatile enough to use for a great varieties of subjects, such as travel, scenic, landscapes, candids, portraiture on locations, stage and equally great for shooting flash photography.

What makes these zooms so handy is that they can be used in place of three fixed focal length lenses in popular focal length from a moderate wideangle, standard and a short telephoto. The first 35-70mm marketed by Olympus was believed to have been a Zuiko AUTO zoom 35-70mm f/3.6 along with a subsequent S.Zuiko followed up model, S-Zuiko AUTO zoom 35-70mm f/4.0 which aimed to counter price comparison from third party lens manufacturers who started flooding the market with cheaper alternatives. The third Zuiko variation actually was an specialized AF zoom introduced in 1984 to showcase Olympus response to emergence of interest in autofocus technology. Two years later, another entry level optic, MF Zuiko zoom with variable apertures, S-Zuiko 35-70mm f/3.5~f/4.5 was introduced while another subsequent lense with an almost similar configuration in an OM label, S-Zuiko AUTO zoom 35-70mm f/3.5~f/4.8 was debuted along with OM-2000, the last of the MF OM SLR model. Some later versions of these Zuiko zooms have raised some controversial issue in relation to their original source of manufacturing but still they are a Zuiko and I think it is not very appropriate for me to raise this issue here without any truthful confirmation for such speculations. Well, which means to say, there were actually FIVE Zuiko 35-70mm zooms being introduced thus far. Although it may not be entirely true to interrelate all these lenses as they have been introduced in sequential order and more importantly, each of them came with a varying degree of specification and functions but some within the series, a few selective ones have managed to cruise through difficult period in an ever-changing market place to remain in the Zuiko lense group for many years. As a observer, the only shortfall you can complaint on this section of the Zuiko lense group is, it lacks a high speed version to offer OM photographers all these years.

Zuiko AUTO-Zoom 35-70mm f/3.6

This lense is one of the original OM effort designed for the all popular 35-70mm focal length. Despite its long history in lense development, with its excellent lense handling characteristic and outstanding optical performance, this solidly made Zuiko optic is widely regarded as the best Zuiko 35-70mm lense produced thus far by Olympus and comparable to many top class wide-tele zooms made by rivaling brands.

Specifically designed for zoom photography in the wide angle to moderate telephoto range. It measures only 74mm in length (minimum, on telephoto setting) and weighs 400g - the most heavy optic in Zuiko 35-70 class but still can considered as highly portable and making it very convenient for everyday use, regardless it is for professional application and/or casual shootings. With the maximum aperture of f/3.6, it assures fast, accurate focusing on the central microprism spot in the screen. Another feature is, correct focus is maintained throughout the zoom range, while delivering simply outstanding performance where some OM faithful claim even comparable to corresponding fixed-focus lenses. In view of the complexity in its optical compositions where comprises of an 10 elements in 8 groups design, the lense is multicoated in its native form to minimize flare and ghost images.

Among the few available options in the Zuiko lense group, this 35-70 zoom almost priced double than a comparing Zuiko equivalent, the S-Zuiko AUTO zoom 35-70mm f/4.0 (indicative prices for used , mint unit may range between USD240.00-USD320* while the S-Zuiko counterpart priced almost halved at prices between USD125.00-USD160.00* in mint, used condition). One way or another, these indicative pricing reflects how Olympus separates and valued the two Zuiko in different perspective but even on its own, this lense does able to withstand the test of time despite seeing sequential introduction of other Zuiko 35-70mm with differing spec, price and handling to challenge its position - in particularly at the time where one touch zoom with macrofocus design was beginning to take shape as mainstream zoom design. *Source: MacBroom's Camera Blue Book.

In fact, amidst all the eventful happenings occurred during this period, in a 1992 OM system brochure, this lense was still listed in Zuiko lineup at the 35-70mm category, this shows how well OM photographers have prized this lense over the rest and constant demand could well be the main reason enabling it to sustain for that long in the Zuiko lense family.

With its reasonably compactness which provides high portability and an extremely versatile focal length that spans across from a useful wideangle (63° at 35mm) to mid-tele (34° at end of its range) zoom range, the lense is suitable for both in serious professional usage and/or for general PR photography including family and scenic pictures, occasions such as weddings, parties, candids etc. providing for free selection between close-ups of individuals, and group portraits in a restricted area. The lense accepts a 55mm threaded fitter and the rubber lense hood that provided as standard accessory may be reversed for convenience in storing.

Well, I don't know why Olympus cannot made this lense set at a maximum aperture of f/3.5 which is more "universal" for reference when specify lense speed. Anyway, it has remained as the one and only lens-type with such "odd" lense speed and indeed, it carries a very original "Olympus" flavor in its own right ....
