I just got the new 24-70 to replace my Mark I version of the lens. Here is my question, given that the new lens has a diameter of 5mm more, does that mean that more light enters the lens? I presume yes. So, following that presumption, shooting the same subject in the same lighting at the same aperture and ISO speed, does the 82mm lens need less time to properly expose the subject? If it does, it follows that the new lens is better in low light, correct?
Unfortunately, I sold the Mark I lens the day before the Mark II arrived in the mail so I was unable to test the theory.
