“Why is called a constant aperture lens when the photo of the lens shows a range of FStops? Confused?”

• Hi Ludi, Sony commitment to customer satisfaction is our top priority. The SEL2470GM2 lens is marked F2.8 constant-aperture because it can stay constant at its maximum aperture, which is at F2.8 on all focal lengths available on this lens. In comparison, a non-constant lens, like the SEL100400GM, will change aperture whenever you change the focal length. For any questions or concerns, you can reach us at 239-245-6360.   Regards, Larry 12-15-2023 Sony Social Support
