Zuiko MC MACRO 20mm f/2.0 (Current Version)

This Zuiko macro was probably introduced between 1983/1984. Along with few other Zuiko macro lenses introduced at the same time, these lenses feature the world's first* automatic diaphragm for high magnification works in conjunction with the OM system macrophoto units. There were two main improvement made to the older version. The lense now incorporates a fast f/2.0 maximum aperture for bright viewfinder image in critical fine-tuning focusing and/or photo composition. The automatic diaphragm also enables full aperture metering with capable OM bodies.

Overall, the superior optical design with multicoated lense coating ensures its high resolving power yields faithful colour reproduction and maintaining high contrast images across the entire focusing/aperture range. As depth of field is one critical element for extremely high magnification works, stopping down the apertures is almost a must. Further, choice of focusing screen types can help in ease of focusing as well as for high rate of successful macrophotography. Use exclusively with an OM Bellow Unit, Extension Tube 14, 25, 65-116 and/or OM Macrophotographic Equipment such as PMT-35.

The lense offers a Max. 5.7mm x 8.6mm (4.2X) ~ Min. 1.8mm x 2.6mm (13.6X) in photographic range. Please note, Olympus does not encourage the use of normal shoe mount electronic flash and even the T8 Ring flash. Instead, use the newer T10 Ring flash 1 and do not use the Ring Cross Filter POL. The lense cannot use a slide-on filter as with the older lense version. Strangely, this Zuiko only provides a minimum aperture of f/16 which I thought is a little inadequate for its working range especially this Zuiko macro can yield an extremely high magnification at an amazing 13.6X !

Specifications:

Focal length: 20mm
Maximum Aperture: 1:2.0

Zuiko MC MACRO 38mm f/3.5 (discontinued)

The original OM macro lenses also comprised of this 38mm lense. However, probably because of the availability of the 20mm which yields a higher magnification and usually that is all matters when someone is intended to get into such a lense type and naturally the 20mm lense will have an advantage as a more logical purchasing consideration over the 38mm lense. Anyway, no doubt information for this lense is scarce and hard to come by and if you have other references and/or personal experience with its usage and/or handling, please furnish us to enable all to benefit.

Similarly in its objective and purpose, this lense is also aimed to exert high resolution and contrast at high magnifications max. 20mm x 13mm to a min. 6mm x 4mm photographic range. As the lense does not has Helicoid mechanism for focusing and it works via Auto Bellows and an optional coupling attachment such as an objective lens Mount PM-MTob is necessary to bridge between the units.

As high magnification works require absolute stillness and artificial illumination, the use of a steady support and auto flash is required for successful photography .recommended. The right choice of focusing screen types may improve focusing (see below) as this lense does not has automatic diaphragm. The lense uses a slightly larger diameter of filter (32mm slide-on type). The PMT-35, a highly sophisticated macrophoto apparatus, Is available for advanced amateurs and skilled experts. In a similar lens update program by Olympus occurred in 1983/1984, along with the 20mm upgrade, this Zuiko Macro lense was substituted by a faster version Zuiko MC Macro 38mm f/2.8.

Zuiko MC MACRO 38mm f/2.8 (Current Version)

This revised version was one of the fruitful research by Olympus optical engineers to improve the previous 38mm macro lense. It was among the few that rolled out during a broad scale Zuiko lense updating program during end of the first quarter of the eighties. Designed to use exclusively with an array of OM macrophoto system accessories such as AUTO Bellow Unit and Auto Extension Tubes 14, 25 and 65-116, it can also be used with highly sophisticated professional OM Macrophotographic Equipment such as PMT-35. Other than giving a speed boost from f/3.5 to a brighter f/2.8, it also incorporates with an automatic diaphragm to enable full aperture metering with virtually all applicable OM SLR bodies.

In many ways, this Zuiko 38mm f/2.8 MACRO lense shares many similarities in its technical configuration with the 20mm f/2.0 counterpart. Other than having a differing focal length of 38mm, a full f-stop slower in its maximum lense speed at f/2.8 and a varying minimum/maximum filed size, the lense weighs, measures and even shares a same diameter with the Zuiko MC MACRO 20mm f/2.0. Unlike the 20mm which can yield a maximum magnification of 13.6X, this 38mm Zuiko Macro projects a Max. 14mm x 21mm (1.7X) ~ Min. 3.6mm x 5.4mm (6.7X).

As the lense configurations are different from previous versions, Olympus reminds the older T8 Ring Flash can not be used and when use in conjunction with the T-10 Ring Flash 1, the Ring Cross Filter POL is not advisable to use together in such combination. Filters cannot be used with this lense.
