I know you're supposed to turn the knob until the viewfinder becomes sharp but what's the point of having the knob when you turn it right, it becomes foggy? What's this icon for "I +" (an upside down t in the middle). Canon EOS 60D/Sigma 30mm F1.4 EX DC

Is negative on the left(-) and positive on the right(+), or the other way not too sure right now. But anyway, you adjust it to suite your eyesight as everybody doesnt have the same tolerance. “You can easily judge the character of a man by how he treats those who can do nothing for him.” --==Gear List & Feedback==--

Because its hard to see through your view finder with glasses on. Especially if you wear bifocal or trifocals glasses. I'm sure it wouldn't be a problem with contacts.

Accurate focus begins with making sure the focusing screen itself is in proper focus. EOS DSLRs have a diopter adjustment dial next to the viewfinder that allows you to adjust the sharpness of the AF points. To make sure your eyes focus on the AF points rather than a scene, point the camera towards an evenly lit wall without a lens. Adjust the diopter dial until the AF markings are as sharp as possible. If you aren’t able to get the AF points into sharp focus by using the diopter knob you may need corrective lenses. 7D Gripped
