First Exposure: Canon MP-E f/2.8 65 mm Macro by Jack
& Sue Drafahl
The magnification limit for most macro lenses has generally
been around the 1:1 reproduction ratio (lifesize). This is not due to
photographers lack of innovation, but rather restricted due to the
laws of physics. When you venture beyond 1:1, the properties of light
are harder to control through small apertures. Photographers who do venture
beyond the world of 1:1, resort to such devices as extension tubes, lens
extenders, bellows, or reversing rings. These work, but not without extensive
testing and sometimes frustration.
Canons solution was to extend the limits of conventional macro lenses
by building the MP-E 65mm f/2.8 macro lens. It starts at 1:1 magnification
and continues to an incredible 5:1 ratiothats 5X lifesizewithout
the aid of any extra gadgets. This lens sounded too good to be true, so
we arranged for a test drive into the super macro world where few photographers
dare to go.
Our first glance told us that this was indeed a unique lens. Weighing
in at only 31 ounces, its 1:1 compressed size is a scant 98 millimeters
with a standard picture field of 36 x 24mm. It then can be rotated 487
degrees to 228 millimeters to achieve a 5:1 magnification. At the 5:1
magnification, a miniscule subject 7.2 x 4.8mm will fill the entire 36
x 24mm frame, capturing minute subject detail often undetected by the
naked eye. Thats what really makes this lens special.
The 65mm macro lens has an f-stop range from f/2.8 to f/16, although most
macro work is done at the smaller apertures. Lens construction features
10 elements in 8 groups, including 1 UD (Ultra-low Dispersion) glass element
to minimize chromatic aberration. It also incorporates Canons ElectroMagnetic
Diaphragm (EMD) for fully automatic exposure control. This macro lens
has a special detachable tripod collar, takes 58mm filters and is compatible
with all Canon EOS cameras.

This is a fully manual focus camera with a range from
4 inches at 1X to 1.6 inches at 5X. As you expand the lens, there is a
magnification scale to provide accurate magnification readings. Electrical
contacts on the back of the lens communicate information to the camera
regarding lens mode, lens type, metering information, focal length, and
absolute distance of the lens. Because of the unusual construction of
the lens, it is not compatible with extension tubes, extenders, or additional
closeup filters.
So much for the technical jargon. We know you want to see how it works
in the field, but first lets get it straight about the focus system.
This is a manual lens by sheer necessity. If you have ever tried to autofocus
a macro lens at 1:1, it will drive you crazy. There are so many focus
points in a macro scene, the autofocus will constantly search, moving
in and out trying to achieve accurate focus. Most experienced macro photographers
find this impractical and turn the autofocus off, even if their lens has
autofocus capability.
Manual focus is even more critical as you increase the magnification to
5:1. It is almost impossible to hold still on a focus point at this magnification,
so we found it necessary to brace the lens or camera as we were shooting.
In many of our tests, we found it easier to set the front edge of the
lens on a firm surface, and slowly move into the focus point.
We also found it difficult framing the subject at 5:1 as you can hardly
see with the naked eye what you are photographing. The subjects are so
small that we suggest practicing your focusing. Take a newspaper and zero
in on a specific word at each magnification until you become proficient
at framing your subjects.

We tried several types of films with this lens and found the best to be
the ISO 100200 slide films. These films feature the tightest grain
pattern and can resolve the intricate subject detail capable with this
lens.
You will need to be selective in your choice of subjects depending on
the magnification you use. As you increase toward the 5:1 magnification,
you will need to consider flatter plane subjects than with the 1:1 magnification.
Insects and flowers are great at 1:1, but the surfaces of leaves, skin,
or man made materials seem better suited when you reach the 5:1 range.
This is not because there of a problem with the lens, but rather the restrictions
in the laws of physics. The fact is that at 5:1 magnification, you have
almost no depth of field, even at f/16. You can shoot 3D subjects at 5:1,
but the laws of physics will limit how much focus you can maintain.
We highly recommend the use of a variable power or TTL flash, as you will
want flash duration speeds shorter than normal. At full power, most flash
units are about 1ž1500 flash duration, which may not be enough when at
5:1 magnification. If you keep the flash head close to the front of the
lens, your TTL flash should cut off at about 1ž8 to 1ž16 power which will
increase the effective flash speed up to 1ž16,000 of a second. If you
want to guarantee high speed, use the manual flash setting for 1ž8 to
1ž16 power and move the flash to compensate for the right exposure.

We have been doing macro photography for more than 30 years and never
seen a lens like this one. It is lightweight, easy to use, and has an
ability to change from 1:1 to 5:1 like no other macro system on the market.
One word of warning, though. You will not get 36 great pictures with your
very first roll of film, especially if you are new to macro photography.
We suggest that you concentrate your effects at the 1:1 magnification
first, and then progress to the higher magnifications as you become more
proficient with the lens.
This is not the lens for everyone
just those brave souls who want
to venture into the relatively unknown world of the small. You will experience
sights few people have ever seen, and have pictures to document your adventures.
Canons MP-E 65mm Macrophoto Lens takes you to the world of macro
and
beyond.
Suggested list price for this lens is $1600. For more information, contact
