What is the difference between DX and FX format lenses?

Asked 6 months ago
The main difference between DX and FX format lenses lies in their image sensor coverage. DX lenses are specifically designed for Nikon's APS-C sized image sensors, resulting in a reduced field of view compared to FX lenses. This sensor size crop factor increases the effective focal length of DX lenses by 1.5 times, making them ideal for capturing distant subjects. On the other hand, FX lenses are intended for Nikon's full-frame FX format cameras, which have larger image sensors. They provide a wider angle of view and do not undergo any focal length crop. FX lenses are suitable for professionals or those seeking a broader field of view, while DX lenses are a cost-effective choice for most photographers looking for versatility and flexibility in their images.
