Olympus OM system close-up and macro equipment

Zuiko Auto-Macro Lens 135mm f/4.5

Introduction

This is one of the second generation of bellows macro lenses for the Olympus OM system and was first produced in 1980. Like the other second-generation lenses, this one has an automatic diaphragm and a focusing helicoid to assist fine focusing.

This lens is intended for use with the Auto Bellows or the Telescopic Auto Tube 65–116; its built-in focusing helicoid can only be used for fine-focusing, and the rear of the lens extends beyond the bayonet lens mount, so it is not possible to mount the lens directly on a camera.

Unlike the other bellows macro lenses, this one can focus to infinity. Its longer focal length provides a longer working distance that the other macro and bellows macro lenses.

When used with the Auto Bellows, the Double Cable Release is needed to activate the automatic diaphragm.

Accessories

A hard leather case was supplied with the lens. A clamp-on rubber lens hood was available.

A Calculator Panel for the T Power Control 1 was available for use with this lens and the T10 Ring Flash 1, with the distance scale in both feet and metres. Self-adhesive labels were provided with the T Power Control 1 to stick onto a Calculator Panel to provide readings for manual flash with the T10 Ring Flash 1, T8 Ring Flash 2 and T28 Macro Single Flash 1.

The Macro Flash Shoe Ring screws into the 55 mm filter mount, and takes the heads of the T28 Macro Twin Flash 1 or the T28 Macro Single Flash 1.

Going digital

When the Zuiko Auto-Macro 135mm f/4.5 is mounted on the Auto Bellows attached to a digital body, the only ways to close down the iris diaphragm are to use the cable release socket or the stop down lever on the lens mount of the bellows. When it is mounted on the Telescopic Auto Tube, OM/EOS and OM/Four Thirds adapters change the automatic diaphragm to manual click stops.

The following tables are based on those in the instruction leaflet, with adjustments for different sensor sizes and for any additional extension needed to allow the release lever on the rear of the bellows to clear an overhanging pentaprism or flash.

ZUIKO AUTO-MACRO 135mm 1:4.5

Coupled with the Telescopic Auto Tube 65–116 or Auto Bellows, this lens performs medical close-up as well as outdoor action photography. Especially when used with the telescopic 65-116, the lens permits automatic diaphragm control just as an ordinary lens 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 F4.5, the lens provides F4 brightness when looked through the viewfinder, making composition and focusing easier.

The lens is designed to achieve magnifications around 0.2× and features a working distance range from 37cm (0.5×) 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 and medical subjects), the photographer can remain conveniently far from the subject and that, in general photography, the lens can be used in the same way as an ordinary 135mm telephoto. 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 increases as magnification factor becomes greater. However, the Electronic Flash T32 (or T20) or the T10 Ring Flash solves this problem, making close-up photography more easy and more fun.

The lens is multi-coated, but in order to safeguard against flares with backlight conditions, always remember to use the lens hood for fine definition.

Compatible focusing screens are 1-4, 1-10 and 1-11.
