I was out shooting with my brother-out-law’s Pentax ME yesterday, and really enjoying it. I was chasing the sun over the hill toward Cambridge, plinking at the neighborhood with a roll of color film. I stupidly forgot to bring another roll with me, and tried to race back to my apartment for more film, but the light changed before I had a chance to get out again. Drat!
But the Pentax ME was really a lot of fun. When you trip the shutter, the whole camera gives an almost imperceptible hop. The iris closes, the mirror jumps up, the first curtain is chased by the second curtain across the image plane, the mirror jumps down, the iris opens again–all in a fraction of a second, all with a very satisfying, almost ceramic-sounding “Clink!”
It says, “Yes!”
But that hop, when the whole camera almost pops in your hand–that’s absolutely delightful, and strangely familiar. Where have I felt that hop before?
Oh–right.
My motorcycle did the same thing.
Imagine standing over a 400-lb machine. You stand it up and balance it between your feet, straighten out the handlebars, and turn a key. A couple of lights show up on a rudimentary instrument panel. You make sure a certain green light is on, then you squeeze the clutch lever and press the starter button. The machine gives a short, staccato cough, and suddenly it’s rattling and vibrating and oscillating uncertainly under you, like a nervous dog waiting for its command, the crankshaft spinning at about 20 times per second, the camshafts at half that speed, each spark plug firing ten times per second, each valve opening and closing five times per second, metal clutch plates spinning and rattling idly in a bath of oil. The whole thing is vibrating and ringing under you, some of the sounds at certain frequencies finding their way through your helmet’s padding and into your head.
And then you squeeze the clutch lever and stomp into 1st gear, and the whole thing gives an eager hop and says, “Yes!”
This camera and the motorcycle were of the same era, during a transition from all-mechanical to mechanical/electronic control. The motorcycle, at least my early 1980 Kawasaki KZ550, was all mechanical, right down to the contact breaker points which pinched open and closed to fire the ignition coils. Though it was designed a couple of years earlier than the KZ550, this Pentax has more brains than the Kawasaki, and it takes a few tentative steps into electronic control: you select the aperture, and the electronic meter determines the shutter speed. You can see what the meter is doing when you peer into the viewfinder, and see the little LEDs light up next to a corresponding shutter speed. It can be a little fiddly (I was running into weird metering issues with it as the sunlight failed the other day), but the tactile experience is still fundamentally mechanical, and fundamentally satisfying in a way that purely electronic devices are not.
Now, as we work to eliminate any and all mechanical components from electronic devices–expunging mechanical disk drives and other spinning platters from our computers, removing mechanical linkages and controls from our cameras, even banishing control cables from bicycles–the tactile, mechanical experience is becoming more and more elusive.
The mechanical experience isn’t easy to achieve with a device that is mostly electronic. (It was easier in the machine age, before integrated, programmable electronics became truly commodified and ubiquitous, and before mechanical linkages were replaced by electrical contacts, servos, and integrated circuits.) It can be done, but it takes a great deal of engineering and expense now to get it right. (Auto companies now spend millions of dollars engineering tactile/mechanical/aural feedback back into their cars, after the now-compulsory electronics and hydraulics have taken them out.) That’s why a satisfying mechanical experience costs so much now: the electronics are cheap, but the springs, buttons, cams, levers, bearings, and click detents that make up a mechanical interface all have to be designed, fabricated, tested, and integrated into a largely preexisting digital matrix–and that’s a much larger part of an engineering budget than the integrated circuits and resisters and capacitors, all of which can ordered off the peg.
