Understanding the True Focal Length of APS-C Lenses

Understanding the True Focal Length of APS-C Lenses If you've ever dabbled in photography, chances are you've come across the term "APS-C sensor." Sounds fancy, right? But what does it mean for your lens's focal length? Let’s break it down into bite-sized pieces so that even your cat, who’s probably more photogenic than you, can follow along. What Is an APS-C Sensor? Before diving into focal lengths, it’s worth understanding what an APS-C sensor actually is. Cameras come with different sensor sizes, and APS-C is one of the smaller ones compared to the full-frame sensor. The term "crop sensor" is often used for APS-C, and no, it doesn’t mean your camera is hungry for pixels. It just means the sensor is physically smaller, cropping out part of the image that a full-frame sensor would capture.
