This i-Function lens is perfect for novices and experts alike. If you're a beginner, shoot confidently like a pro with Lens Priority Mode. This allows your camera to instantly recognise the type of lens you've attached. Now, it will serve up optimal scene modes with i-Scene, while i-Setting optimises all the settings for the perfect shot. If you're already a pro, you can cycle through and adjust shutter speed, aperture, ISO and more all without taking your fingers off the lens, and your eyes off the shot simply by pressing the i-Function button and turning the value ring to the desired settings.
