Pentax Spotmatic SLR Camera
Nostalgic Review
Are our modern cameras really better ?
Author AndrewS May 2013
Introduction In the late 1960's and through the 1970's
all my photos were made with a Pentax Spotmatic
SLR film camera. For much of that time I had only one lens, a Takumar 50
mm f1.7. There was no such thing as a
zoom lens for consumer cameras.
That was the heyday of street photography, an activity all
but banned in these anxious times. I
made some of my all time favourite photos with that camera. You can see a few
of them with this article.
Why review an
(almost) 50 year old camera ? This
blog is about camera ergonomics. Some
modern cameras which I have used are dreadful kludges, with truly awful
ergonomics. Others are not bad at all. I thought it might be interesting to
compare the old with the new to get some sense of progress (or lack of it) in
camera design over the last 50 years or so.
Description and
Features The Spotmatic is (you can
still buy an old one on eBay) a mechanical single lens reflex camera which
takes 35 mm perforated film in preloaded cassettes. Image size is 24 x 36 mm. Lenses
are interchangeable, using the 42 mm screw mount which was popular with several
makers in the 1970's. The really big deal which the Spotmatic brought to
consumer photography in 1964 was Through the Lens Metering. At first this required the lens aperture to be
stopped down, which made metering a deliberative business. Open aperture
metering arrived with the Spotmatic SP-F in 1973. Batteries are required for
the exposure meter but everything else works manually. Despite the name, the
meter is of center weighted averaging type, not a spot meter, although I
believe an early prototype may have featured spot metering.
The camera body and lenses are very compact. Body dimensions
are Width 143 mm, Height 92 mm, Depth 49 mm. The box volume is 645 cc. No
current model "full frame" DSLR comes anywhere near this compact
size. In fact no DSLR using the APS-C sensor size, which is less than half the
area of 24 x 36 "full frame", is as small as the Spotmatic. Even the
recently released Canon EOS 100D has a box volume of 735 cc.
You can still buy new cameras like the Spotmatic. For
instance the FM10 is still in Nikon's current catalogue. This is an all manual
camera made by Cosina for Nikon, having a list of specifications and features
almost identical to the Spotmatic.
Image Quality Most of the Takumar lenses were of excellent
quality. Like many others, I mostly used Kodak TRI-X film, which gave decent
resolution and good sharpness. The film
had excellent dynamic range and exposure latitude, which it needed, as exposure
metering was not as accurate as one gets from a modern camera. Overall I like
the appearance of prints made from my Spotmatic negatives. They lack the absolute resolution of modern
cameras, but have good tonal gradation and are plenty sharp enough for most
purposes.
Performance With no autofocus, no motor drive and no auto
exposure system, you might be excused for expecting the Spotmatic to perform
poorly. But that is not the case. With a
good understanding of the principles of camera operation and plenty of
practice, the experienced user can in fact extract very good performance from
this camera. One learned to preset focus and exposure when moving into a
situation. I would commonly use an
understanding of hyperfocal distance to pre set focus distance and
aperture. With these presets, shot to
shot times were determined by the speed with which one could operate the film
wind lever. I found one shot every two seconds to be quite realistic.
Ergonomics
Setup Phase There being
nothing remotely resembling a menu, Setup consists of reading the instruction
manual and getting plenty of practice using the device.
Prepare Phase This
involves loading film and setting the film speed. In many situations it would also involve
presetting focus distance, aperture and shutter speed. These settings would normally
be considered part of Capture Phase
with a modern camera. But they take a little longer with the Spotmatic. This in turn means more anticipation is
needed so when the "decisive
moment" appears, one only has to press the shutter button.
Capture Phase
Holding The Spotmatic and many cameras like it have
the "no handle" design which actually works decently well because
there is no monitor (or anything else) taking up space on the back of the
camera. This means the right thumb can be angled across the back, allowing the
index finger to fall naturally onto the shutter button.
Viewing The camera has a proper glass pentaprism and
decent viewfinder optics giving a clear view of the subject.
Operating The keyword here is simplicity. Focus is
controlled by turning a ring on the lens with the left hand. Aperture is changed with another ring on the
lens barrel, also using the left hand. Shutter speed is changed via a dial on
the top plate. To do this the right thumb and index finger have to move up a
little from their basic positions, which disrupts grip with the right hand
while shutter speed is being adjusted.
The exposure meter is activated and lens stopped down by pushing a
little lever on the upper left (as viewed by the user) side of the lens mount.
Film wind on to the next frame is achieved by swinging the rewind crank using
the right thumb.
All these actions are simple, direct and specific. They just take a little longer to perform than
the equivalent actions with a well designed modern electronic camera. This
could be considered a disadvantage but with practice the camera is actually
quite easy to use and quick to operate. The art of anticipation is an essential
operating requirement.
Metering is perhaps the least endearing part of this camera's operation. It involves stopping down the lens then changing
aperture and/or shutter speed to move a
needle (visible in the viewfinder) up or down. The process is a bit slow and in
my experience the results not as accurate as a modern camera.
Review Phase This
involves finishing a roll of film, rewinding it into the cassette, developing
the film then making prints. There is of course, no chance to review photos
immediately after capture.
What did I yearn for in the years I was using the Spotmatic ?
Mostly I wanted to be able to change film speed in mid roll. Some other capabilities came to mind at the
time. Faster, more reliable exposure metering was one. Another was for some
kind of film resistant to airport X Rays. That's about it, really. I never
wished and still don't care much for the great majority of features found on
modern cameras.
Comparison with
modern cameras
What have we gained ?
Auto Exposure Auto
Exposure arrangements on modern cameras are a marked improvement on the clunky system
employed by the Spotmatic. Exposure is
calculated then Aperture, Shutter Speed and ISO set in the millisecond between
half and full press of the shutter button. Now we have Exposure Modes, with P,A,S and M
available on a Main Mode Dial. We have one (or two, or three) control dials for immediate adjustment to
Aperture and Shutter Speed.
These features greatly streamline exposure metering and
setting of primary exposure parameters.
The curious thing is that some makers of recent model cameras do not
seem to understand the ergonomic benefits of these technologies. For instance most Sony NEX cameras have no
Mode Dial, including the top of the range NEX7. Fujifilm's (FujiFilm ???) X100/100s, X-Pro1 and X-E1 have no Mode Dial and retain the same
basic control layout for Aperture and Shutter Speed as that found in the
Spotmatic and film era Leica M cameras. I struggle to comprehend why camera
makers fit their products with an odd or antiquated user interface which
prevents the user from fully enjoying the benefits of the modern technology which they posess.
Autofocus Any camera
maker which failed to develop AF in the late 1980's and early 1990's was doomed
to failure. For the snapshooter, AF is an imperative technology. However, for
the expert user I think the benefits of
AF have been somewhat oversold. I used
manual focus cameras of one kind or another for 55 years and rarely in that
time felt a pressing need for autofocus. However since the advent of autofocus
I have many times been frustrated and
disappointed by the failure of a camera's AF to focus correctly or by the way
AF reduced my options to preset focus manually by scale.
Ability to set active AF/MF area anywhere in the frame This is something mirrorless cameras can do
well and I regard it as a really useful feature.
Change ISO anytime This
is so obviously useful, no more need be said.
Video Most cameras now
do competent video. Some are capable of broadcast quality motion picture output.
Image preview/review The
benefits of image review immediately after making the exposure are obvious.
However modern EVF's also allow a preview of the image which is about to be
captured, with display of the effect of exposure compensation, white balance,
etc.
Configurability I include this as a benefit but it could
equally be seen as a curse. Modern cameras are so complex and have so many
features and options that they must be user configurable. There is no option to
avoid the options, so to speak.
What have we lost ?
Simplicity Like
innocence, once lost, simplicity cannot be regained. Modern cameras have literally billions of
possible combinations of menu items and user interface options. They are
drowning in a welter of complexity. The
Spotmatic has five user interface
modules controlling camera operation, each with just one function. This spartan interface is enough to get the
job done.
Compact size, body and lenses
The Spotmatic is smaller than any DSLR on the market today, even those
with the smaller than half frame APS-C sensor size. The lenses are also compact
with no need for autofocus function.
Ability to pre set focus distance and aperture by depth of field scale Some modern lenses especially primes for the
43 mm diagonal "full frame" imager size do have this facility. But
most lenses these days are varifocals which by nature cannot use a focus
distance scale. Even primes often lack a distance scale.
So, are modern
cameras better than old ones like the Pentax Spotmatic ? In my view, they are better in some ways, not
so good in other ways. The Spotmatic and cameras like it, engage the user in a way
which the modern electronic camera cannot match. The Spotmatic does nothing automatically. In
order to use the camera effectively one must learn about the principles of
photography, understand the relationships between film speed, aperture, shutter
speed, camera movement and depth of focus. The user must practice anticipating
photo opportunities, preparing the camera ahead of time as the environment
alters, anticipating subject behaviour and working the controls efficiently.
Could a digital
version of the Spotmatic be viable ?
Technically, I guess it could be made but it would tick so few of the
marketing boxes which camera makers and possibly buyers seem to regard as
essential these days that I doubt it would sell.










Excellent review and how right you are!
