First Look Innovative New Minolta Maxxum 7
By Peter K. Burian January, 2001

When used with D lenses and an HS(D) flash unit or the built-in
flash, the Maxxum 7 provides highly advanced flash metering.
In either low light or outdoors, flash exposures are more
often accurate due to Advanced Distance Integration technology.

Just when we thought that cameras
had reached the maximum level of technological achievement, Minolta engineers
raised the bar significantly. Their new Maxxum 7 took a giant step beyond
our expectations with some truly innovative technology. Resembling a digital
SLR camera with its huge rear-mounted LCD monitor, it is a hybrid of familiar
and futuristic with the large, conventional knobs plus entirely new controls
and capabilities.
When Minolta reps first demonstrated
this new system behind closed doors in August 2000, I was overwhelmed.
Would I need to become a computer programmer to actually use the Maxxum
7’s multimode Navigation Display and some of its accessories? Apparently
not, since an hour with the instruction manual--plus occasional reference
later--proved to be all the education that I required. While shooting
a few preliminary rolls of slide film, I became adept at accessing the
most valuable of the unique features quickly.
This brief report is not based
on a full test so it is simply a preview of the technology and Maxxum
7 capabilities. Nonetheless, I did spend enough time with the camera,
new 5600HS(D) flash, improved Vertical Grip VC-7, and a new D-series lens
to offer a glimpse at their advantages. Look for a full test report with
evaluations in a future issue of Shutterbug. In the meantime, consider
the following information as to the incredible potential of this Maxxum
system.

With D lenses, the Maxxum 7 provides very specific feedback
on exact depth of field in the Navigation Display panel.
This unique feature is far more useful than the preview
feature alone, or the depth of field scales on some old
lenses. (A 24-105mm f/3.5-4.5D; 5600HS(D) flash; Elite Chrome

Camera Overview. This
is a relatively compact body with some large control knobs and switches
similar to those of the pro Maxxum 9. Naturally there are some electronic
buttons, too, and a new focus area selector switch on the camera back.
The latter is useful and easily accessed by both left and right-eyed photographers.
A small door under the Navigation panel hides less frequently used controls
but these are well marked like all the others. The flash mode selector
switch is on the right side of the body, a logical location. The high-eyepoint
finder is surprisingly bright and offers unusually high magnification--0.8x
for ease of manual focus--plus diopter correction eyepiece.
Navigation Display. This
1x1.5" oversized LCD panel provides more information than any other camera,
a vast range, in fact. At first, this may lead to information overload,
but you can ignore anything not of immediate interest: you press the [DISP]
button to scroll to other screens with other data displays. When the camera
is held in a vertical orientation, the display changes to vertical format--a
great idea. Since I am near- sighted, I especially liked the extra large
numerals and the illumination in low light. And the information as to
each Custom Function--in simple text--will be very useful; there’s
no need to carry a cheat sheet as a reminder of the meaning of each of
the 35 extra functions.
The single most useful feature
for photographers will be the depth of field bar graph, available only
with D-series lenses. Focus on a subject, set the desired focal length
and f/stop, and press the depth of field preview button. Now the display
panel provides very specific data on the range of apparent sharpness:
from 6-22’, for example. Change the focal length, point of focus,
or f/stop and the display provides the new data. Especially in low light
at small apertures--where the viewing screen becomes very dark with depth
of field preview--this feature should be greatly appreciated by serious
photographers.

In time, much of the other
available data will probably become useful, too, such as the scene brightness
distribution display. This allows for a quick review of scene contrast:
the exact relative brightness factor in 14 areas. Most photographers will
never use all of the available data, just as they will not use all of
the Custom Functions. Still, everyone should appreciate the technology
and possible applications these provide.
Superior Focus System. The
Maxxum 800si already included a highly successful AF system, but the Maxxum
7 has more advanced technology with improved algorithm. According to Minolta,
the 16-bit CPU of the Maxxum 7 has a data processing speed about five
times faster for double the speed of focus tracking. The new nine-point
AF system--with line sensors at various angles for reliable focus on any
type of pattern--covers a very large area for framing flexibility and
effective tracking focus. The central point has two sensors with both
a + and x shape, a first for Minolta. This is said to increase focus accuracy
with slow (to f/6.7) lenses and fast (f/2.8 or greater) lenses. Any of
the nine points can be selected or simply set the camera for automatic
focus point selection with the rear-mounted controls.
The new AF/MF button allows
for instant shifting between manual and autofocus with nearly all AF lenses.
Focus can be manually changed after focus is locked in Single Shot AF
mode, if desired. All this is made possible by an in-camera clutch mechanism,
a first in the Minolta system.

The Maxxum 7 has the most advanced AF technology of any
Minolta camera. Its nine-point AF sensor system, focus area
selector switch, and focus override ability make autofocus
reliable and controllable. (A 24-105mm f/3.5-4.5D; B+W Polarizer;

Important Accessories. The
new D lenses and HS(D) Program flash units offer several advantages worth
clarifying. The D lenses include a distance encoder used in Advanced Distance
Integration flash photography with one of the new HS(D) flash units or
the built-in flash. By adding distance and Guide Number information to
the flash exposure calculation, bright (or dark) subjects or backgrounds
are less likely to create exposure errors. With other flash units, four-segment
or Average TTL flash metering is selectable. When using a new HS(D) Program
flash, high-speed synch becomes possible even in wireless off-camera flash
photography.
Note, too, that D lenses are
required for the camera’s depth of field bar graph to operate. Apparently,
all other capabilities operate perfectly with other AF lenses and flash
units, although an HS-model flash is required for high-speed synch. Because
the Maxxum 7 body includes a built-in Distance Encoder, distance data
is considered with multi-segment metering (without flash) with any Minolta
AF lens. So there’s no urgent need for D lenses or HS(D) flash units,
although they do offer advantages with the Maxxum 7.
The new optional Data Saver
DS-100 accessory allows download of shooting data to a SmartMedia card--with
data storage capacity for hundreds of rolls--for subsequent viewing on
Navigation Display or uploading to a PC. This is useful if such data is
important, because the camera’s built-in memory can hold data for
only seven rolls.
Minolta got a lot of accolades
for the new Vertical Grip VC-7 accessory, an ergonomically designed battery
pack that is quite convenient. Its full set of secondary controls--placed
in a much lower, more comfortable position--should make vertical shooting
a pleasure. This accessory also accepts AA batteries, an inexpensive power
source.
Other Great Features. Minolta
has included several capabilities worth noting. Interesting exposure control
options include AE Lock useable with Manual operating mode for equivalent
exposure settings at a variety of aperture/shutter speed combinations;
a dual exposure compensation dial that can be set for 0.3 or 0.5EV increments;
and a versatile AE bracketing mode.
Other useful amenities include
mirror lockup with the 2 sec self-timer, film chamber lock to prevent
accidental opening in mid roll, and smooth trans focus control for defocused
image areas without the need for a special lens. And if you reload a partially
exposed roll of film, the camera can be set to automatically wind to the
desired frame number. There’s a great deal more of course, as noted
in our Features section. All this makes the Maxxum 7 system one of the
most versatile and technologically advanced SLR cameras ever.
