I used EOS 100 for a few years and still love this camera. The quietest motor drive I have ever heard, perfect autofocusing even with low contrast subjects, the viewfinder information just enough to work comfortably, yet not not disturbing. The built-in flesh, although not very useful in darkens due to low power (as in the case of all built-in fleshes), is perfect for natural light portraits to lighten shadows and make catch-lights in eyes. The available options and programs are more then sufficient - if you like gadgets, there is even a bar-code reader for transferring pre-defined photographic situations into the camera's memory! Well, I have never used this toy, still it might be fun. However, the IR remote control is a perfect solution: you don't need to plug-in anything to the camera, you don't even need to touch it when making pictures. Just turn on your IR control, point to the camera and fire!

Ideal camera? Certainly not! For some reasons, which I am not able to understand, there is no single camera on the marked that I would call 'ideal'. Some have such idiotic flaws that it is hard to imagine where an engineer could get those ideas from! In the case of EOS 100 one thing especially drives me nuts (and, unfortunately, this is not the only Canon with that problem): no 'flash OK' confirmation! Yes, there is a 'flash ready' light in the viewfinder, but the camera does not tell you AFTER firing the flash if the subject was in the flash range. Gosh! My old Praktica did it! My Yashica did it! Virtually every modern camera does it! Although in most usual situations this might not the major problem because you can judge the usable distance roughly, in macro photography, which is one of my main subjects, this can really drive you crazy. When using complicated sets of extension tubes and lenses and your working aperture number sometimes gets up to 45 or more, it is really hard to guess what is the flash working distance; OK- you can calculate that, but with such subjects as, say, jumping spiders there is not much time for calculations.

One more stupid idea planted in this camera is the IR remote sensor mounted ONLY at the FRONT of the camera. It is fine for self-portraits (but who really needs it - you have a self-timer anyway), but not very convenient for taking normal photographs. You mount your camera on a tripod, point to that beautiful butterfly, want to fire and... you need to put your hand with IR controller to the front of the camera! Stupid? Sure it is!

My camera also seemed to have a tendency to underexpose flash pictures slightly. This may be a matter of taste to some extent, but at least in macro photography the underexposure was too large for me to be acceptable. After some more 'Canon experience', I am starting to think that this is a general property of Canon cameras - see my comments on EOS 50E.

I still think that it is a very good camera and if you are considering buying used equipment, the EOS 100 may be a good choice. I did not have any problems with this camera and - as far as I know - it still serves well the new owner.
