This would mean that if you were shooting with a 100 mm lens, you would use a minimum shutter speed of approximately 1/100 s . The closest shutter speed to this would typically be 1/125 s.
Ef- S The Super Precision Matte focusing screen is optimized for wide-aperture lenses from f /1.8 thru f /2.8. Areas that are slightly out of focus appear more out of focus, making it easier to tell when focus is right-on. It is ideal for users who frequently use manual focus in dim light with fast lenses.
Canon's EF- S lenses have adopted an optimized optical system and mechanical structure to accommodate an APS-C size sensor that is smaller than a 35 mm full size sensor.
