Super-Telephoto lenses - Zuiko AUTO-T 600mm f/6.5

HTML Page (31k) Loading ...

The super telephoto is not a lens you can casually take along everywhere you go. It is not that easy and convenient to use either. Their narrow angles of view, weight, size and size often restrict mobility and offers very poor portability. Although they are particularly suited for shooting sports, news, wildlife observation and other types of specialized photography such as inaccessible events or places for photographers. These super telephotos are not inexpensive and usually only large agencies or governmental institutions can afford them. Although considerably lighter and more compact than many comparing brands, but some of these Zuiko super-teles are very difficult to cater for normal handheld shooting and it would require a monopod/tripod or any other form of steady support The 600mm has only halved the angle of view of a normal 300mm while the 1000mm has half the angle of view of a 400mm. More important, the 600mm is only about 4 degrees in its angular field of view where the 1000mm Zuiko is even narrower at 2.5°. In most cases, these lenses will be used at their maximum apertures because most of the time, one would need the fastest possible shutter speed to stop the action. You can consider using it with high-speed color or black-and-white film types to help solve part of the problem. Further, the use of automatic film advance devices like a motor drive or power winder would help a a lot and offer a better balance between camera and the heavy lense. The use of cable release is always encouraged if you have all the time to prepare a shot. Zuiko's long telephoto lense group is obviously not Olympus' strength and over the years, the Company pays little attention to its lense development program to update this category of specialized super-tele Zuiko lenses.

F-Zuiko AUTO-T 600mm f/6.5

Introduced among the many original Zuiko lenses with the OM system. With an angle of view of only 4°, this 600mm super telephoto produces images 12 times the size of those produced by a standard 50mm lense.

As with most lenses of such a long focal length, the considerable increase in size and weight was unavoidable. However, with an ingenious optical design, an unprecedented telephoto ratio of 0.7 was achieved. Although comparatively very compact in size, the incorporation of newly-introduced optical glass enables images with superb quality be delivered across its entire focusing range. There is no obvious image cutoff in the viewfinder with any of the higher end series of OM bodies. The lense features a removable built-in retractable lense hood design and accepts a 100mm filter at its front. The tripod ring is rotatable allowing easy operation for horizontal and vertical camera positioning. High resolution and contrast is achieved across its entire aperture range, together with astonishing compactness for easy carrying which makes this Zuiko lense very appealing to certain group of photographers.

Within its considerable physical size with a compromised lense speed, Olympus optical engineers still manage lower the weight factor down to just 2.8kg (98.8oz) and with an overall length of 377mm, this Zuiko lense is still considered one of the most compact in its class. The older version which has been around since early seventies is called E-Zuiko Auto-T 600mm f/6.5 and has similar optical construction with subsequent newer version.

Early version may not have been multicoated but those shipped after 1984 may carry with a "MC" designation which indicates multicoated optic, besides, Olympus claimed a newer optical glass types has been employed in the MC version to substitute older optical glass types. This tele-lense has a rather stiff suggested list price (new) of USD2,000.00* -USD2,200.00 a unit and used units (mint) may still fetch as high as between USD1,380.00* -USD1,450.00 a unit. *Source: MacBroom's Camera Blue Book.
