The Canon EOS 10s (merely EOS 10 outside the USA) was introduced in March, 1990, at the same time as the EOS 700 which I reported on earlier (link). Two lenses were also introduced at the same time, the EF 35-135mm f/4-5.6 and a singleton in the EF lineup, the EF 30-80mm f/4-5.6 PZ - PZ stands for "power zoom". I'll come back to the latter lens later. Other accounts of this camera are found at link, for just one example. The 10s was normally supplied with the EF 35-135mm f/4-5.6 USM, although mine came with the EF 35-80mm PZ (Power Zoom) lens that was more usually the "kit" lens on the 700. The 35-80 PZ is a little hard to find, so it was more the "object of my desire" in this case than the camera it was being sold with. In any case, since I had already covered the 700 model, I went ahead and shot the test roll for this camera using the lens I got with it. The major innovation in the EOS 10 was the development of the Multi-BASIS AF sensor. In the 10, this had three focusing points, hence the "multi-basis". One-Shot AF and predictive AI Servo AF are available. The camera in the Full Auto mode also detects whether the subject is still or moving from the Multi-BASIS points and automatically set the AF mode. The focusing points could be selected automatically or manually. Another featured addition was the built-in bar scanner, yes, bar scanner. A booklet of bar codes was provided to automatically set up the camera for different kinds of shots. The was during the George Walker Bush presidency, during which the President was supposedly amazed by the existence of bar scanners (but see link). I remember bar scanners for personal computers during this period that would scan in code for programs (in Applesoft Basic as I recall). There are, of course, still scanners in every shop nearly; but this did not turn out to be a major addition to camera technology, although apparently some current Blackberry type cameras may scan in bar codes, but not for picture control. I don't have the bar code book, so I don't know how it works. At least it doesn't seem to respond to my box of corn flakes. The 10s was supposed to be one of the smartest cameras up to its time, but I don't think it was that smart. Then again, who knows what the cereal and the camera are up behind my back? Some examples of the codes at (link) included such things as "Wedding with candlelight" Like the 700, the camera has a built-in flash and the two cameras are similar in appearance as the second picture below shows. The 10s was considerably more complex in its capabilities, while remaining very easy to use. It was received with acclaim, winning both the Japanese Grand Prix for 1990-1991 and the European Camera of the Year for 1990-1991. In terms of specifications, the EOS 10s has a fixed eye-level pentaprism with 92% coverage. Various view screens were available for it. It has a vertical-travel, focal-plane electronic shutter with speeds from 30 sec. to 1/4000 sec., B. X-sync at 1/125 sec. Film advance was 5 fps, still very respectable. There is also a built-in interval timer for intervals from 1 sec. to 23 hr. 59 min. 59 sec. for frames 2 to 36. This is a feature I didn't try out for this report, but I will definitely use at some point for a series of some kind, maybe the same scene over the course of a day or some such. Cool. Unlike the EOS 700, but like modern higher-end EOS digital cameras, there is an LCD panel that displays the settings in use. The viewfinder display shows the AF points, shutter speed, aperture setting, and a number of other indications. Like so many of the earlier EOS cameras this used a 6 V 2CR5 lithium battery. The camera has a mass of 625g There is also a camera shake warning. Eh? I turned it off and set the custom function to take pictures even if the shutter speed was too "slow". Standing there pushing the shutter release while the camera tells me it's too dark or too slow or too shaky to take a picture is too much like a "Nanny camera" for me. I want it to do what I want. No Nikon F ever told me when I couldn't take a picture, by golly, no matter how stupid it thought I was. (Am I guilty of personification here?) A puzzlement to me is that there seem to be two ways to turn off the camera-shake alarm - through the custom function 14 and also with the "electronic input" dial. I just turned as much of it off as I could. At least one "shake" warning is based on the inverse of the focal length of the lens rule. There's really a quite diverse set of "Shooting Modes" on the command dial: 1. Manual 2. Camera-shake Alert 3. Depth-of-Field AE 4. Aperture-Priority AE 5. Shutter-Priority AE 6. P 7. L (off) 8. "Green zone" full automatic programmed - the green rectangle still with us Programmed Image Control (P.I.C.) 9. Portrait 10, Landscape 11. Close-up 12. Sports and 13. the Bar code mode. Selection of these is via a command dial with the usual EOS symbols we still have for the most part. The oddity for me was that to turn the dial off "Off" (cunningly disguised as a red L, as it was in those days), you had to push down a central button. I don't remember encountering this before, but perhaps it is on many of the EOS cameras I've never handled. There's a warning in the manual not to turn the command dial without first pushing the button. Another shooting mode is Flash AE (A-TTL or TTL program flash AE with built-in flash). There was also a August, 1991, special commemorative model of the 10s to commemorate Canon selling 60 million cameras worldwide, Both it and its 'normal' EF 35-135mm lens were outfitted in a silver finish instead of the usual black (link). They sold together for 140,000 yen, the same price as for the black camera and lens a year earlier (the advertised price for a regular model out of New York in 1994 was mostly CALL, but some retailers listed it at $290, and the lens was another $270). This was a limited edition that also came with a numbered "gold" medal. How limited, I do not know, but from one serial number reported there may have been as few as a 1000 or as many as 9999, given a four-digit number with leading zeros.
