Canon EOS 600 - Manual (Page 62)

Viewfinder information
If it is impossible to get the distance range in
focus, the lens minimum aperture value will start
blinking. Exposure, however, will still be correct
and you will get the best results under the existing
shooting conditions

Helpful Hints
1. Move back from the subject and follow steps 1
through 4 again If the minimum aperture
stops blinking, the distance range will be in
sharp focus and the exposure will be correct
2- Use a wide-angle lens (or wide-angle side
when using a zoom lens) and follow steps 1
through 4 again. If the minimum aperture
stops blinking, the distance range will be in
sharp focus and the exposure will be correct.
3. Depth of field will be shallow if two points are
focused at the same shooting distance A tele­
photo lens is recommended for portraits in
order to strengthen the shallow effect
