## What's The Difference?

The lens and lens mount are different. The 27mm standard lens was designed from the ground up specifically for the 65R and provides the highest image quality.&#x20;

The 27mm lens, with its wider FOV, is ideal for large-area mapping and broad coverage applications, reducing the number of images needed per flight. The 60mm lens, with its narrowere FOV and finer GSD, is best suited for high-detail imaging in infrastructure inspections, surveying, and precision measurements where accuracy at a distance is critical.&#x20;
