ISO sensitivity on new cameras?


Question


ISO sensitivity on new cameras?
Given the advanced technology on new cameras lately regarding ISO sensitivity, does it still makes sense to buy lenses with wide aperture opening at about . or . or even . which cost a lot when all you do it increase your iso setting when taking pictures in dark environment? Or am I missing something here?


Answer


Yep! Youre missing something. As well as allowing shots in low light a wide aperture lens allows very shallow depth of field to isolate the subject from the background.
