Zuiko MC MACRO 90mm f/2.0 (Current Version)

A very late addition to the superb OM Macrophoto group was an Zuiko MC MACRO 90mm f/2.0. Probably introduced in late eighties, the technical highlight of this lense is its remarkable fast maximum lense speed with an ideal telephoto focal length at 90mm. The lense has its own Helicoid focusing mechanism which enables it to extend its focusing to infinity and thus, it can double function as a normal medium range telephoto optic. What are the advantages offer in a tele-macro lense ?

Basically, it is the extra working distance that makes the difference. It permits and allow the photographer shooting at a comfortable distance while maintaining enough subject distance for non-disturbance of the natural habitats of nature, easy picture composition, using fill-in flash and others. Probably one equally important aspect is the natural perspective a telephoto offers than to a standard lense and/or shorter focal length in close-up photography.

Next, the fast maximum aperture of f/2.0 makes viewing, focusing and picture composing such a joy to use with this lense. Image at viewfinder remains extremely bright and clear at all times with full aperture metering and without any need to change focusing screen type with some older OM bodies. Although in many ways, its main objective is to shoot macrophotography and would require stopping down the aperture down to smaller values, but when use the lense as a normal medium telephoto for normal photography, the f/2.0 aperture offers a greater level in depth of field control for photographers.

Although I don't deny the fact OM Macrophoto group provides wide arrange of system accessories that can truly call it very versatile system but a helical focusing Macro lenses do have their distinctive advantage at times over accessory-aided macro lenses in terms of flexibility and mobility it offers to photographers in particularly on location shooting. Unfortunately this lense was introduced at quite a late stage where I would assume most OM photographers who may be interested in such kind of optic could have built a system on their own, if not, I can imagine it may turn out to be a popular choice as it doubles as a top quality normal medium telephoto.

The lense can close focus down to a minimum distance of 0.4m (15.7"). At this distance, the maximum reproduction ratio is 1:2 half life size. With Auto bellow, it can reach 1:1. But a higher magnification is via the Auto Extension Tube 65-116 where a 1.72X is reachable Combination with other Auto Tubes such as: Tube 7=0.08X ~ 0.58X; Tube 14=0.16X ~ 0.65X; Tube 25=0.28X ~ 0.77X; Tube 7+14=0.24X ~ 0.73X; Tube 25+7=0.36X ~ 0.84X; Tube 25+14=0.44X ~ 0.92X; Tube 25+7+14=0.52X ~ 1.0X. This Zuiko has a close range optical correction system incorporated within the mechanism to compensate aberration that might arise when focusing at close range. This has ensure the superior optical performance be extended down to its closest working range.

Zuiko MC MACRO
135mm f/4.5 (Current Version)

This is one of the few most popular Zuiko Macro lense type, primarily because of its long reaching telephoto range which facilitates easier handling and shooting of macrophotography. Coupled with the Telescopic Auto Tube 65-116 or Auto Bellows, this lenss performs medical close-up as well as outdoor action photography.

Especially when used with the telescopic 65-116, the lense permits automatic diaphragm control just as an ordinary Iense does. With the Auto Bellows. automatic aperturing is achieved by the use of the Double Cable Release. Although its maximum taking aperture is rated at a rather slow f/4.5, the lense provides f/4.0 brightness when looked through the viewfinder, making composition and focusing easier, naturally, good choice of focusing types may also be helpful for sheer comfort in viewing, focusing and picture compositions. (Olympus suggests the use of compatible focusing screens types such as 1.4, 1-10, 1.11, 1-12 and 1.13).

The lense is designed to achieve 0.2X magnification and features a working distance range 37cm (0.5X) to infinity (with Auto Bellows). This means that, in close-up photography, even when it is not possible to get close to the subject (such as insects end medical subjects), the photographer can make use of the generous working distance and remain conveniently far from the subject.

Besides, in general photography. the lense can also be used in the some way as an ordinary 135mm telephoto lense. Unlike many other macro lenses that were designed for similar purpose, this lense is equipped with a fine focusing mechanism to facilitate and enhance its performance further.

Additionally, the long focal length produces close-ups which are not subject to exaggerated perspective effects. In general, the possibility of blurred images caused by camera shake increase, at magnification factor becomes greater. However, the Electronic Flesh T32 (T20 or equivalents) or T10 Ring Flash may offer a practical solution to solve this issue, making close-up photography more easy and more fun to handle with.

The lense is multicoated, but in order to safeguard against flares with backlight conditions, always remember to use the lense hood for fine definition. The lense uses a very straight forward optical construction of 5 elements in 4 groups which probably explains partly the superlative image quality it offers. With combining this lenses with good selection of system accessories, this lense can really shine in performance.
