information on Olympus Zuiko Lenses
A 40mm focal length standard lense ? In a world where photographers are running dry on ideas been chasing illusive dreams via use of widevision lenses and long reaching optic to create compressing perspectives, it is indeed quite strange to see Olympus added a new member in the Zuiko lens family with a 40mm focal length with 56° picture angle. It is neither classified as a wideangle lense nor carries a normal angle of view similar to other ZUIKO standard lenses. Besides, it comes with a middle of the road f/2.0 maximum aperture which falls short from other standard lenses to refer it a perfect standard lense. So, why would anyone wants to buy a 40mm lense with every of its features fall at midrange specification ? Especially with the immense popularity of zoom lenses today, most new photographer would rather have a fascinating zoom lense bundle with his first purchase rather than buying such a non-eye catching pin-size lense - probably a test in our wisdom, huh ?

Well, at least a few camera/lense manufacturers thought it was quite logical to assume there will be a market for such unique lense type. Although I can recall Contax was the first to experiment with a debut of two of such pancake lenses, Tessar 45mm f/2.8 T* MM and followed by an updated Tessar 45mm f/2.8 T* AE mount back in the '80. On the other hand, company like Nikon also has a pancake lense at 45mm, 45mm f/2.8 GN Auto Nikkor(1969) which carried a different objective in experimenting a simplified flash control method with aperture coupled to the lens diaphragm. As its name GN (guide number) suggests, the lens employs the guide number coupling system for automatic diaphragm adjustments. The lense was soon phased out due to the emergence of auto thyristors flash that gaining momentum as the mainstream flash system during the early to mid seventies.
So, Olympus also decided to join the rank as a pancake lense supplier during its Zuiko lense updating program occurred during the early '80. The lense was believed to have been introduced in 1984, a time Olympus attempted to re-established a footing with debut of a series of exciting next generation of the OM SLR cameras. Well, at the time amidst all the confusion in a market that flooded with as stream of electronic SLR bodies by various players together with the introduction of many cheap entry level zoom lenses, in fact, for the first time, overall sales of SLRs have began to shrink and many potential SLR users are turning away to buy P&S cameras instead. Further, some of the negative aspect of those entry level zoom lenses were also began to surface, the relatively small aperture that closely associated with these zoom lenses makes focusing and picture composing difficult and most of all, the easy variations of picture angles via change of zoom settings makes photography very uninspiring for photographers. Besides, the weak portability attributes from bulkiness of such zoom is another factor that restrict mobility of photographers. Strangely, all of a sudden, getting a lightweight prime lense to enjoy photography has becomes quite logical. The introduction of the highly compact Zuiko was quite timely as it offered a refreshing experience for photographers with everything going back to bare basic.

In fact, the lense combines strength of standard lenses and a moderately wider picture angle midway between a normal and wideangle lenses at a careful chosen focal length at 40mm instead of 45mm as found on other systems. For a brief spell, the lense was quite popular as it offers an exciting new entry focal length for photographers to experiment with its unique features and explore its potential in their photography.
Zuiko AUTO-S 40mm f/2.0
It is easily one of the smallest and lightest of all OM System lenses, with a very useful, slightly wider than normal 40mm focal length that is especially appreciated by press photographers. Minimum focus is an extremely close 30cm. The balance with any OM camera bodies is superb.

This lense has an angle of coverage of 56° which is slightly wider than the human eye's usual field of view (around 50°). The development of this "semi-standard" lense has been realized, reflecting a recent tendency that an increased number of standard lenses are manufactured with a shorter focal length and a wider angle of view. As this lense measures only 25mm in overall length, a diameter of 60mm (9.8") and weighs only 140g, it is extremely compact and light, thereby enhancing the functionality of OM cameras. Its minimum focusing distance is 30cm -shortest among the lenses of this class. It has a 6 elements in 6 group optical design - except in the case of a handful of Zuiko macro lenses, it is the smallest designed Zuiko lense thus far. If you want to pick on something out of nothing, a slight drawback in its aperture scales where the lense only stopped down at f/16 as the lense can also be used as a high quality lense for macro when used in combination with an extension tube, bellow or inverted to used in extreme close-up photography.
OFF TOPIC SUPPLEMENTS: The Contax's Tessar 45mm f/2.8 T* AE/MM lense with a simple 4 elements in three groups design, is so compact that it even looks a little odd when it is mount on any of the Contax SLRs. For an example, a Contax ST has a physical size of 151.5mm x 97.5mm x 55mm depth, so the 18mm length of the lense looks more like an extension tube rather be considered as a picture taking optical lense. The Contax 45mm f/2.8 lens has a 50° angular field, focuses down to 0.6m, a dimension of 60 x 18mm and weighs 90g ! On the other hand, the pin-size Olympus ZUIKO lense, has a more logical specification, because I don't think compactness should be the priority with a Olympus as after all, the entire OM system is a very compact system on its own, but two important and well though features in usable lense speed and wider angular field are. Thus, Olympus decision to adopt the 40mm and the chosen a brighter f/2.0 is a wide move to edge the competitions.
" ... a legendary Olympus Zuiko Standard 40mm f2 Lens Excellent+++!! perfect glass, perfect function. A HARD to find legendary Olympus OM Zuiko WA 40mm f2 lens in real excellent condition with perfect glass and beautiful metal part, and full functionality. It comes to you with both caps and a 49mm uv or skylight filter. what made this lens special is : it is the smallest, lightest, and thinnest among all OM Zuiko lenses. Sometimes it is called the "Pancake" lens, and it's the largest aperture pancake lens ever made by ALL the lens makers! It never stayed on the store shelf but in the Zuiko-lovers hands since it was ever put on the market. Its optical quality and image effects are astonishing. It is most liked by many pros and photojournalist and being called their "standard" lens instead of the common 50mm versions, even Olympus classifies it as Standard. It is really an indoor and outdoor all-purpose lens to use and proud to own! It is a sharp weapon to use and a collector's delight. It is so unique and so good, no wonder some Zuikoholics say: whenever you see one [40/2], .. . It comes to you complete with the original Olympus front and rear lens caps. And a skylight filter as pictured..." <<< --- Credit: Image courtesy of Jone Quinn <firstname.lastname@example.org> who also runs a popular Ebay Store where you can take a visit to scout for OM used items.
