        IMO, a perfect example of Canon just plain being evil.  I never 
realized how much I subconsciously used the focus confirmation on my MF 
lenses with my -DS until I tried using some on my friend's RebelXT. 
Between the bad viewfinder and lack of focus confirmation, it's extremely 
difficult to focus MF lenses.
