[Leica] Leica Long Lenses on Digital Canon SLRs

[rickfloyd at comcast.net (Richard C. Floyd)]

On my EOS cameras there is a viewfinder cap built into the neckstrap 
for blocking the eyepiece from stray light when your eye is not at the 
camera.  I would imagine the DRebel has the same or an accessory cap 
that came in the box to do the same.  Check the manual for this.
