I thought I'd share a recent purchasing experience with you - I just bough an EOS 3, however, before doing so I did a bit of research on the 'net, and noted some people had experienced problems with a mis-calibrated exposure meter. So, when I went to buy the camera, I took along my trusty T90 and asked the shop assistant to let me compare meter readings. Testing both in spot meter mode indicated a full stop difference (underexposure) on the brand new EOS.
Naturally, both I and the assistant first suspected the old T90, so we compared the EOS to a Nikon F100 - same result. So then we tried another EOS 3. Same problem (not quite so bad though). A 3rd EOS 3 tested satisfactorily.
The lesson here is if buying a brand new camera, check the metering in the shop - its a lot easier than wasting a couple of rolls and taking it back. While the problem with the EOS 3 has (fortunately) been documented, I see no reason why similar problems wouldn't occur occasionally in other brands and models. And personally, I wouldn't want to do business with any camera shop that would not be happy for me to carry out such tests.

The info on the EOS 3 was found in a number of reviews on the 'net - try a web search for "Canon EOS 30 reviews" (make sure you put in reviews or you'll get page after page of sales info!) and see what you find ... you'll probably also get references to discussion lists where you can ask any questions you might have.

Very interesting and ever so helpful comments seeing as I'm getting pretty close to buying an EOS-3 to suppliment my worn out EOS-5, and I wasn't aware of the issues. Thank you. Before I buy, I'll certainly compare the -3 to my current -5.
However, my personal observations is that Canon's EOS metering systems in general tend to be "optimistic" overall, and that on all butt really bright days when you are going for super-saturated colours on Kodachrome, at least a half stop over-exposure is called for anyway. This observation of mine is based on comparison of various Canon EOS cameras versus the T-90/AE-1 combo I had before I went AF - it is true for several EOS models though, because I had different models earlier that were stolen and replaced with newer models.
I actually find that my EOS-5 needs more overexposure in this respect than does my cheap-and-chearful backup EOS-1000FN body (soon to be sold when the EOS-5 is relegated to backup). I guess you pays your money...

Andy - in my brief experience with the EOS, I would tend to agree with you regarding "optimistic" exposures, however, what I'm not sure of is how much this is due to the differing metering patterns of the evaluative exposure system - I'm guessing this will take some time to get used to. But I would expect to get "neutral" results using spot metering across any range of cameras - I would say 1/3 rd of a stop is probably within manufacturer's tolerances, but anything more is unacceptable ... but at least it is something we can easily check.
Lest anyone think this is an EOS knocking session, let me say that the EOS 3 is a dream to use and certainly the best camera I've ever handled.
