GTC Patron TLS (True Lens Services) knows how important it is to get a clear sense of how a lens performs with different camera set-ups. With this in mind, it built the TLS Lens Coverage Tool, a simple, interactive way to explore lens coverage across a variety of sensors.
With this tool, you can:
- Compare lens coverage across different camera set-ups
- View the image circle for each focal length at different T-stops and focus distances
- Easily check whether your chosen lens fully covers your format
It’s designed to give you useful insight quickly, helping you plan shoots with confidence and make informed decisions.
