The FD
50mm f/3.5 Macro, the FD 100mm f/4 Macro, and the FD 200mm f/4 Macro
are lenses for a relatively moderate range of photo-macrography. However, the outside
limit of photomacrography is about 20X, beyond which you need a microscope.
 |
 |
The Macrophoto Lens 20mm f/3.5 and the Macrophoto Lens 35mm f/2.8 are designed for magnifications of up to 20X. With the 35mm Macrophoto lens and a Canon bellows you can photograph at up to 5X magnification. |
With the 20mm and a bellows, magnification reaches 10X. By adding extension tubes between bellows and lens, 20X magnification is attainable.
NOTE:- Info on the NEWER autofocus version
However, Not all SLR
manufacturers (even apply to third party lens manufacturers) offering similar dedicated
macrophoto lenses. Only Olympus (Who carries the most extension lenses and accessories
in this category), Canon and as well as the Minolta has such optical solutions (Minolta
has two bellow lens in 50mm and 100mm and additonal two bellow-micro photo lenses
of 12.5mm and 25mm). <<<

Generally, as focal length decreases so does minimum focusing distance. However,
these Macrophoto lenses should not be confused with conventional short focal length
lenses. For example, they show none of the perspective characteristics of wide-angle
lenses and they cannot
be used for conventional photography and most if the time, it is used in combination
with a bellow unit and focusing stage. The barrel design for the 20mm and 35mm Macrophoto
lenses is highly functional. The longer of the two is slightly more than 20mm in
length and both have tapering barrels that allow light to reach the subject even
at extremely short lens-to-subject distances. For instance, separation between lens
and subject for a 10.72X magnification is only 16.7mmóabout the width of a
finger.Further other optical characteristic of such lenses is usually come with correction
of lens aberrations ó particularly comaóis extensive, thus ensuring
more faithful color rendition and retianing high level of sharpness even at extreme
magnifications. Things to note when using such lenses in
macrophotography and more or less apply in general: there's little margin for error
in photomacrography. Nothing less than critical focusing and a steady camera will
do. A number of tripods are adaptable to photomacrography, particularly where you
need an extremely low camera position for nature shooting in the field. Canon also
makes copy stands, macro stages and other devices for solid camera support.
Focusing technique for photomacrography is somewhat different than for conventional
shooting. First, try to accertain and determine the desired magnification. Find
the extension you need and adjust the bellows accordingly. With the Canon Auto Bellows
you then can make fine focus adjustments by moving the camera/bellows/lens unit as
a whole. Then close the manual diaphragm of the Macrophoto lens to the desired aperture,
meter and press the shutter button, preferably with a cable release. Detailed instructions
and shooting hints are provided with the Macrophoto lenses, Auto Bellows and other
close-up system accessories.

FD-EOS Macro Lens Mount
Converter
While limiting the focusing
range to close-up shooting distances, the FD-EOS Macro Lens Mount Converter can
be used to attach any lens or accessory with an FD mount (NOT
the other way round)
 |
This converter facilitates highmagnification photography with specialized FD system macro accessories, such as the Auto Bellows, 20mm and 35mm Macrophoto lenses, and the Photo Micro Unit F. |
Because these FD accessories have no electronic contacts, certain EOS functions such as autofocus confirmation, automatic diaphragm control, and spot metering (on the EOS-1 or equivalent bodies) are not possible. However, stop-down metering is possible in other patterns such as evaluative, partial and center-weighted averaging.
MP-E65mm
f/2.8 Macro Photo Lens
Recently, Canon has
introduced quite an interesting macro lens. It is called the MP-E65mm f/2.8 Macrophoto
Lens. It is designed exclusively for high-magnification close-ups from 1X to 5X without
the need for a belows unit. This manual focus lens is fully compatible with
all Canon EOS cameras which previously has to depend on accessory like FD-EOS
adaptor to mount
 |
Photomicro lenses onto thew EOS body when such magnifications are required. It is a highly-corrected, 10 element (including one UD-glass element to minimize chromatic aberration) high quality optical lens. It also utilizes a 3-group floating system to further improve sharpness at all levels of magnifications. Further it also incorporates Canon's ElectroMagnetic Diaphragm (EMD) for fully automatic exposure control. |
Working distances range from 4
inches at 1X (life-size) to 1.6 inches at 5X. The extended focusing range subsituting
any need for bellows units, making the lens highly highly flexible and portable.It
comes with a detachable tripod collar and takes 58mm filters, as well as Canon's
Macro Ring Lite ML-3.
The Bellows FLM 100mm
F4.0 Lens
The FLM 100mm F4.0 lens
is a short mount lens with automatic aperture designed to be used exclusively with
Bellows FL, and then it expands possibilities from general photography to close-ups
and macrophotography. It focuses continuously from infinity to macro distances.
 |
It has 5 elements in 3 components which give it a high resolving power It corrects aberration most satisfactorily making its color balance truly perfect, with high contrast and sharpness throughout the entire image plane. |
It has double the focal length
of a standard lens, so there is more space available for lighting, etc., without
disturbing the shooting operation. Besides, its 100mm focal length delivers natural
perspective.
