Olympus OM Equipment for Close-up and Macro Photography

Zuiko Auto-1:1 Macro Lens 80mm f/4

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. The inclusion of a focusing helicoid means that this lens can also be used on extension tubes; the shortest combination that allows an image to be brought into focus is 7 mm + 25 mm.

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

This lens replaced the Zuiko 1:1 Macro Lens 80mm f/4, which has a manual (pre-set) diaphragm and does not have a helicoid for fine focusing. The Auto version is a new lens design, not just the earlier lens in a new mount.

Accessories

A hard leather case was supplied with the lens. A Mirror Housing was made to fit this lens. A dedicated close-up lens made specifically for this lens increases the maximum magnification with the Telescopic Auto Tube 65–116 to 2×.

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 49 mm filter mount, and takes the heads of the T28 Macro Twin Flash 1 or the T28 Macro Single Flash 1.

ZUIKO MC AUTO-1:1 MACRO F4 f=80mm

Specially designed for macrophotography, copying and close-up work to deliver optimum resolution at 1:1 reproduction when used with the Telescopic Auto Tube 65–116 or Auto Bellows. Especially when used with the telescopic 65–116, it makes an extremely convenient macro lens (½× – 2×), as automatic diaphragm control and meter coupling is possible. With the Auto Bellows automatic aperturing is achieved by the use of the Double Cable Release.

Generally, ordinary lenses and conventional macro lenses cannot reproduce life-size images with critical definition, while this is the world’s first 1:1 macro for use with 35mm film.

In close-up and macro photography blurred images caused by camera shake become increasingly exaggerated as magnification ratio becomes greater. However, thanks to the Electronic Flash T32 or T10 Ring Flash, taking of razorsharp macro photos has become within each reach of every photographer. For advanced amateurs and professionals, a macrophoto stand and highly sophisticated PMT-35 macrophoto equipment are available in the OM System. A Closeup Lens 80mm is also available for 2:1 macrophotography to be used with this lens and the 65–116.

The lens is multi-coated and accepts a 49mm threaded filter. Compatible focusing screens are 1-4, 1-10 and 1-11.

CLOSE-UP LENS 80mm MACRO f=170 mm

This high quality close-up lens is specially designed for use with the ZUIKO MC Auto-1:1 Macro 80mm F4 lens to extend its magnification range with the Telescopic Auto Extension Tube 65-116 from 1× to 2×.

Screw the close-up lens into the MC Auto-1:1 lens.

	Rotate the close-up lens counterclockwise to remove.
	If it is hard to unscrew the close-up lens, use a wrench provided.

Care for Use and Maintenance:

1. Do not leave the close-up lens in high temperature and humidity.
2. if the unit is rapidly transmitted from low to high temperature places, it will sometimes become moist with dew. Wipe It off carefully.
3. Do not screw the unit with excess force.
4. Avoid the use of this unit with any other lenses than the MC Auto-1:1 Macro 80mm.
5. Avoid the use of this unit for photographic magnification 1.2× or lower (since the Macro 80mm lens brings a better result without the close-up lens in such a case).
6. F numbers 5.6 or larger (for smaller lens apertures) are recommended for better results.
7. If a filter is hard to remove from the close-up lens, hold the close-up lens and rotate the filter, pressing on its knurled ring, or use a wrench provided, inserting its pins into the recesses on the lens flange, and unscrew.
