From Protege:
The Product Concept
In the
development of the Pentax MZ-S, our product concept was simple and clear from the very
beginning: we wanted to create a top-class 35mm SLR camera that would combine solid,
reliable performance with the ultimate operability. At the same time, we did not want to
sacrifice the compact dimensions of the camera body, which photographers from around the
world have come to expect from our MZ-series SLRs. In the past, we introduced both a
high-tech digital control system (as in the Pentax Z-1p) and a user-friendly dial control
system (as in the MZ-3 and the MZ-5N). Both systems, however, had their pros and cons.
Designed for advanced photographers, the Z-1ps digital system offered such
sophisticated features as a centralized display system and the Hyper" exposure
modes, but its state-of-the-art control system was a little too complicated for some of
users to get accustomed to in a short period. On the other hand, the MZ-3 and MZ-5Ns
analog-type direct-access dial control system was easy to understand and operate even for
beginners, but some of the features did not function as flawlessly as the digital
systems. Frankly speaking as camera designers, we thought it would be much easier to
standardize the entire control system one way or another. For the optimum benefit of our
users, however, we decided to harmonize the best of both worlds to develop a totally new
hybrid control system for the new MZ-S.
First, we made a
thorough review of each and every function and selected the functions which we believed
were absolutely necessary to achieve the level of performance we expected from this
camera. To keep the compact dimensions, there was no room for frills or gimmicks. Then, we
decided which function went best with which control. Naturally, some functions suited the
digital system, while others were easier to operate with the analog system. Finally, based
on the importance and frequency of use, we divided the selected functions into two groups:
the first group of functions, which are required frequent on-the-spot setting changes,
must go onto the camera body for quick access. The second group, which are fundamental in
essence
and dont require
frequent changes after the initial settings are made, were assigned to the Pentax
Functions (PF). The Pentax Function feature also contributes to the elimination of
accidental setting changes during shooting.
Top Panel Design
When we talk
about the cameras operability, we are most concerned with two important factors of
the camera design: accessibility and readability. Accessibility involves the shape and
position of switches, buttons and dials; readability is mostly affected by the body design
and display method. We knew from our experience that, in order to improve these factors,
we must do something drastic to the MZ-S camera body design. After some research and
discussion, we found the ideal solution rather easily: we just needed to slant the top
panel toward the photographer by approximately 30 degrees and position the control dials
on this slanted plane. Imagine, for instance, that you have a computer, a clock,
stationery and several family pictures on your desk. You feel more comfortable by
positioning some of them diagonally, so all of them are facing you, rather than setting
them parallel to the front edge of the desk. Or imagine your car. Its much easier to
drive and get the information you need if all the meters and switches are facing toward
you. Likewise, we concluded that this unconventional design could considerably improve
both the accessibility and readability of the controls and displays on the top panel. We
also figured the rest of the body design and the interior layout would follow accordingly.
But it was easier said than done. This drastically slanted top panel was the core of our
body design concept. It allows you to read the settings and make changes more easily from
various angles: there is no need to raise your eye level when you take your eye from the
viewfinder, and you dont have to stand on tiptoe or use a chair or box during
high-angle shooting with the camera set on a tripod.
Next came the
design of two control dials. Its unusual to have a digital-type dial on one side and
an analog-type dial on the other, but this was the result of our extensive review of the
camera functions. We concluded that the functions that the user decides by absolute
numerical value, such as shutter speed, aperture and exposure frame number, were better
accommodated by digital operation. Consequently, these factors were assigned to the
digital dial on the right side and their settings are displayed on the LCD panel
positioned inside this dial. In comparison with the Z-1ps centralized display
system, which is positioned on the top of the pentaprism and away from the control system,
this in-the-dial display system makes data reading and setting changes much easier. On the
other hand, the factors that are decided by relative value, such as exposure compensation
factor and auto bracketing factor, were assigned to the analog dial on the left side. In
addition, the two reference points of this analog dial (the "zero-point" index
on one side and the PF" mark on the opposite) are colored with green and red,
respectively, for at-a-glance confirmation.
Exterior Design
Once the design
of the top panel was completed, we turned our attention to the overall body design. The
MZ-Ss novel top panel design greatly affected the rest of the body design, and we
had to design everything from scratch using our advanced three-dimensional CAD technology.
Most of the pentaprism housing was set into the raised front line of the top panel
in other words, protruding less over the line creating a unique appearance from the
front. Unlike conventional cameras, we designed the MZ-S to be asymmetric on both sides of
the pentaprism because it looked a little awkward when we first designed it to be
symmetrical. The two dials were sized differently because, due to an optical illusion
caused by the difference in color and shape, the digital dial looked much smaller than the
analog one, even though they were the same size. So, we designed the digital dial to be
considerably larger and added a small protrusion right in front of the digital dial to
refine the design. Finally, we made other minor design adjustments here and there to make
the MZ-S look sharp and pleasing from every angle.
The Control
System
Our next
assignment was to decide the best layout of buttons and levers, apart from the two large
dials, to ensure optimum operability and accessibility. By this time, we were more
confident with our design concept and became much bolder in designing these parts than we
were at first. The shutter release button, for example, is not only slanted toward the
front, but also tilted slightly outward because we felt it was a more ergonomically
efficient design. We moved the electronic preview lever from its traditional position on
the lens mount section to a spot right next to the shutter release button for easier
access at the shooting position. Because of the unique top panel design, some of other
buttons and levers had to be slanted to a certain extent as well. For instance, the
exposure mode button, which is used to instantly jump the exposure mode from the
Shutter-Priority AE back to the Programmed AE, was placed on the slanted plane on the
upper right side of the front panel an area which previously was seldom used for
such buttons. We also installed the shutter-speed hold switch on the back panel, which
locks the digital dial in order to prevent the accidental shift of exposure modes or
shutter speeds.
Magnesium Diecast
Body
Once the basic
body design was completed, we had to decide on the material used for the body casing. It
had to be strong, durable and lightweight and also convey the high-class image of the
MZ-S. Aluminum and zinc didnt meet these requirements. The material also had to be
flexible enough in molding to reproduce the MZ-Ss complicated shape with great
precision. For this reason, titanium was eliminated. Eventually, we were left with only
one choice: magnesium diecast, used for the first time in a Pentax camera and available in
only a handful of high-end SLRs on the market today. We used this magnesium diecast
material for four major components of the body casing. Compared with commonly used
plastic, this material provides outstanding strength. Take the arms of the built-in RTF
flash unit, for example. They are designed to be very thin, yet they are exceptionally
resistant to twist and distortion.
We also paid
attention to the body coating to make it extra-durable and give the MZ-S an distinctive
appearance. In our exclusive three-layer, three-bake coating process, we first apply a
black base layer, and then a second flat layer. After each layer is applied, the body
parts are carefully baked to provide maximum protection. The third and final layer is
applied by hand to create a sandy surface texture and outstanding holding comfort. The
parts are baked for the third time to perfection. Since the final layer is hand-applied, a
careful inspection shows that each MZ-S has a slightly difference texture, providing sense
of personality for the user.
Interior Design
Of course, the
MZ-Ss eye-catching design, including the slanted top panel, greatly affected its
interior design. We found that we could use only a handful of parts from other MZ-series
models. As a result, we had to design almost all blocks, both electronic and mechanical,
and wiring patterns from scratch to fit into the unusually shaped spaces. Many buttons and
levers had to be installed on slanted planes, requiring careful calculations and minute
design adjustments. So we had to think very flexibly and creatively to make the best use
of available space. Our industry-leading mechanical and electronic technologies were very
much needed to pack everything into a compact body, which is nearly as small as the
MZ-3s.
New Features
In addition to
its solid performance and unique appearance, the MZ-S offers some outstanding new
features. The first is a new six-point AF system, which has five focusing points aligned
horizontally and one additional point just above the middle point. With these five
horizontal points, this AF system offers the widest AF coverage of all 35mm AF SLRs
currently on the market. It also comes equipped with a back-up mechanism. When the optimum
focusing point has difficulty focusing on the subject because of extremely low contrast or
complete monotone, the neighboring point is automatically activated to enhance focusing
accuracy. You can also switch to the spot AF mode to select one of the six points for
pinpoint focusing on a small area.
The second
notable feature is on-the-film data recording, which is incorporated in a Pentax 35mm SLR
camera for the first time. This new feature allows you to imprint useful data (exposure
mode, metering mode, shutter speed, aperture value, exposure compensation value, and auto
bracketing) onto the films blank spaces between the perforations. It also imprints
the film number onto the film leader section.
Another useful
feature is an exposure frame designation function, which automatically advances the film
to the designated exposure frame when the film is reloaded into the MZ-S. This allows you
to rewind the film midway through, switch to a different type of film, then reload the
original film and resume shooting from the first blank frame without worrying about
accidentally double-exposing already exposed frames at all.
Finally, there is
a single-action AF lock button another first for a Pentax 35mm SLR. With a
conventional AF lock mechanism, you have to first press the shutter release button halfway
down to activate the AF system, then press the AF lock button to lock the focus. However,
this convenient button, which is located on the back panel, allows you to activate the
cameras AF system and lock the focus with just a single push. Since there is no need
to touch the shutter release button, you dont have to worry about accidental shutter
releases. This is also very helpful when wearing gloves in cold weather.
Accessories
In order to
maximize the MZ-Ss outstanding capabilities and cope with a wide range of
photographic applications, we designed a new set of accessories that includes a battery
grip, flash unit and cable switches.
The BG-10 Battery
Grip not only dramatically extends the operation time of the MZ-S, but comes also equipped
with a shutter release button for vertical-position shooting, an electronic preview lever,
an AE lock button and an infrared remote controller. Its ergonomic design further enhances
the MZ-Ss holding comfort and stability, while its single-action lever mechanism
allows for quick, effortless installation and removal. We strongly recommend that our
users pair this grip with the MZ-S camera body.
The AF360FGZ
dedicated auto flash is another great partner for the MZ-S. With a large guide number of
36 at 85mm (at ISO100/m) and a maximum discharge angle of 24mm (20mm with a wide-angle
panel attached), this powerful flash unit supplements the built-in RTF flash in many flash
situations. Its wireless data-transmission capability with the RTF unit automatically
adjusts the discharge level with great precision, even under confusing lighting
conditions.
We also offers
cable switches (in two different lengths), a release timer switch for pre-programmed
interval shooting, quick shoe adapters, and soft camera cases all made of the
finest material and for maximum performance. Of course, the MZ-S is compatible with all
SMC Pentax FA- and F-series interchangeable lenses and most of existing accessories, just
like all other MZ-series models.
The Future Form
of 35mm SLR Cameras
If you think a
cameras control system is too complicated or troublesome for the first time you use
it, you may start to dislike the camera and seldom use it afterward. Eventually you may
stop enjoying photography altogether even if the camera offers the finest
performance and quality. Thats why we were particularly concerned about the
MZ-Ss control system. Because of its unconventional styling, people may at first
glance be a little hesitant to try it out. But once you lay your hands on this camera, you
will be surprised by its outstanding feel and flawless operation. We wanted the MZ-S to be
the camera that people take with them everywhere they go. If you still prefer a camera
with either a digital or analog control system, thats fine because we believe
our users deserve choice. Pentax offers all three types in its 35mm SLR lineup to meet
every users preference. But, by incorporating the new hybrid control system and a
host of sophisticated features into one of the most compact bodies available today
without any frills or gimmicks we are confident that we have successfully developed
a truly epoch-making camera, which points to the future of 35mm SLR photography. We hope
all photographers both advanced and beginners will take the opportunity to
experience the MZ-S firsthand, and see and feel the real difference!"
