Modern Classic SLRs Series :
Canon F-1 - Macro Photographjy

 


When it is used with the standard lens, macrophotography with a magnification from 1 X to 3X can be performed.

A semi-automatic aperture mechanism with which automatically closes the diaphragm makes the Bellows FL almost as easy to use as a fully automatic lens.

Attaching and detaching the Bellows are the same procedure as the how to operate the lens.

The Bellows FL is a three track bellows with both front and rear adjustment as well as overall adjustment. Minute adjustments can be made, and the advantage is : it is seldom necessary to move the tripod.

The Slide Duplicator (see illustration bottom right hand side) can be attached to the tip of the Bellows. Moreover, since the strut for preventing blur is built in, it is convenient to perform shooting with the Bellows attached to the copy stand.

When using the Bellows, it is desirable to use the macro lens which is especially designed for close focusing, however, since the wide angle and the standard FD lenses have been far improved over conventional lenses, when the FD lens is used, very satisfactory results can be expected, prefebly stopped the lens down to smaller aperture value will help a lot.

FD 50mm lens's magnification ratios can be read directly from the Bellows scale engraved on to it.

In addition to the FL, a simplified model, the Bellows M, is also available. It is a single track manual bellows with front extension.

Macrophoto Coupler FL

General photographic lenses are designed for maximum performance at normal photographic distances and, as a rule, the closer to the subject, the more degraded the image. This tendency is remarkable particularly in life-size photography or in higher magnifications. On the other hand, when the lens is positioned at a close distance from the subject, photographic conditions, including illumination, will become worse.

In order to minimize these defects, the lens can be reversed. The accessory for reversing the lens is called the Macrophoto Coupler.
There are two types of Macrophoto Couplers: one' is for attaching to the screw type extension tube and the other for attaching to the bayonet mount. The Macrophoto Coupler for the tube can be attached directly to the screw type Extension Tube, however, since it is not equipped with the focusing device, focusing must be done by the focusing ring of the lens. But when the Bellows is used in combination, focusing can be performed freely with the Bellows.



The
FLM l00mm F 4 (Click here for more info) short mount lens is a high resolution macro focusing lens. The lens is attached to the Bellows and can be focused continuously from infinity to actual life-size. (1:1 ratio). It is convenient in close-up photography, as the focal length is twice as long as the 50mm. For the same magnification, lens to subject distance is greater than with the 50mm macro.

The number of the Macrophoto Coupler denotes the front screw diameter (Filter Screw) of the lens. There are four sizes: 40mm, 48mm, 55mm, and 58mm. The Macrophoto Coupler FL 55 has a helicoid mount and can protrude 13mm. Focusing is possible without a Bellows. It can be attached directly to the Extension Tube M, the Bellows FL and the camera body. Besides, when attaching it only to the standard lens, it is capable of magnifications of 1.3X to 1.5X and is indeed very useful. The 55mm Macrophoto Coupler is designed for use with the standard FD 50mm F 1.4 and 1.8 lenses.


Slide Duplicator FL

The unit is for duplicating slides and it can photograph both film strips and lantern slides. Subjects may be trimmed with this duplicator because it is screwed into the tip of the bellows located between the sliding rails and the lens mounting section. In order to ensure an even illumination of the slides, the unit has a dispersion glass on the back of its film holder. In light metering, correct exposure can be read through the built-in meter of camera. But, when the central area to be measured is covered with black shadow, shift film back and forth a little and then read the meter information. When duplicating slides, pay careful attention to the light source. Apply the flood lamp to tungsten film and natural light to daylight film. Whenever the situation makes selection of the correct light impossible, it may be necessary to replace the filter. It is important to use small lens apertures of less than F 5.6 for duplicating photography, because its depth of field is extremely shallow.




Screw-In Type Extension Tube


These are intermediate tubes that are screwed together. They were initially made for Canon's rangefinder cameras but can also be used on the singlo lens reflex cameras.

The tubes in this category are a set of the Extension Ring A, B, C, 6mm, 9mm, and 12mm and also six tubes for macrophotography with lengths from 25mm to 200mm. However, as these tubes are of the screw-in type, when joining them to the bayonet type of mount, it is necessary to use Mount Converters A and B.

The Mount Converter A is used when the tube is connected to the camera body and the B is used when the tube is connected to the Macrophoto Coupler FL.

Lens Mount Converter A

This is an adapter used when the screw-in type of accessories are attached to the single lens reflex camera mount. It is also used when the screw-in type of lens for the rangefinder camera is connected to the single lens reflex camera.

Lens Mount Converter B

This is an adapter used when the accessories equipped with a bayonet ring for single lens reflex camera and the FD and FL lenses are connected to the screw-in type of tube.
