CANON L PRIMES EF – SET

CANON L PRIMES EF  lenses tend to be more durable, incorporating dust and water-resistant rubber seals on some models. L lenses also contain optics of higher quality, with many lenses containing aspherically ground, fluorite or ultra-low dispersion glass elements. Their front elements do not rotate for the proper operation of some filters, such as circular polarizers. L lenses are often “fast”, with maximum apertures commonly f/2.8 or f/4 and never exceeding f/5.6. Standard prime lenses have a much greater maximum aperture, such as Canon’s current 50mm and 85mm L lenses which open to f/1.2. All current L-series lenses have ultrasonic autofocus motors (USM) and extra communication pins, except for the specialist tilt-shift lenses which do not provide autofocus.
