Since some people have encouraged me, I continue with another historical post on EOS cameras, in this case the model known in the USA as the A2e, but in a slightly different version overseas as the Canon EOS 5 camera. It was introduced in November 1992, and replaced in late 1998 by the Canon EOS 3 camera. This was designed as a "prosumer" camera, but was often used by professionals. What we are seeing here is the maturing of the EOS film cameras into essentially the same control and operating system used by the top end of digital EOS (two-wheel, top-LCD display, and viewfinder display). Its big innovation over earlier EOS cameras was eye-controlled focus-point selection. On this model, however, this only worked with the camera held in horizontal (landscape) orientation. One calibrates eye-control to your own eye. When I first got the camera, I calibrated it and found that the system worked pretty well. However, I confess that when shooting the test roll that provided the examples below, I just let the camera do the work, always watching the active points (there are only 5 anyhow). Actually I found the eye-controlled depth of field preview at least as useful as the focus selection when I tried it. The body is fiberglass reinforced thermoplastic with graphite fiber reinforcement to provide dimensional stability for the lens-to-film plane connections. OMG PLASTIC! Run, the sky is falling! Or at least that was one contemporary response to it. The camera is very light, as a result, although full sized in dimensions. A vertical grip (VG10) grip was available, but provided only vertical controls, not extra power, and did not allow the eye-control to work in the vertical position. I think that this may have been the second EOS camera (after the EOS 1 of Sept 89) to have the two control dials of the later higher end EOS cameras -- the main input dial next to the shutter release and the appearance of the "quick control dial" on the back of the camera. There is one difference that makes the EOS 5 a better buy than the A2e US model. Let Philip Greenspun's comments say it Someone has a U.S. patent, believe it or not, on the use of a digital scale to show under or over exposure in a metered-manual SLR. Canon didn't want to pay this patent holder and therefore turns off the -2/+2 (in half-stops) scale when in metered-manual mode. You get just an over or under indication but have no way of telling how much without dialing back to neutral and counting. The European/Japanese market EOS-5 is not crippled in this manner. (link) The EOS 5 has the automatic film loading typical of the EOS cameras, except with a new twist. There are no sprockets, only a roller bar. Instead, this camera actually uses infrared light to count the sprockets as they go past. It is therefore impossible to use infrared film in the EOS 5! There is a documented problem with failures of the "command dial" (the one with P and Av and such on it), although mine works so far (DIY repair discussion at link or link).
