Can You Actually Use Crop Lenses on a Full-Frame Body? Here's What the Math Says
I’ll be honest: for years I dismissed the idea of mounting a crop lens on a full-frame body. It felt like putting regular tires on a sports car. Why would you intentionally limit a more capable sensor? Then I started digging into the actual math, and it turns out the answer is more nuanced than a flat “don’t do it.” In this Tony & Chelsea Northrup tutorial, Watch the full tutorial on YouTube, Tony walks through exactly what happens when you pair APS-C glass with a full-frame body across Canon, Nikon, Sony, and Pentax systems, and it changed how I think about lens budgeting entirely.
