Broadcast Lens Calculator provides estimates based on published manufacturer specifications and standard thin-lens approximations. Results are for pre-production planning purposes only and should not be relied upon as the sole basis for equipment decisions.
Always verify your lens and shot parameters on location before committing to a setup. Rental lenses may have non-standard modifications (adjusted back-focus, close-focus adapters, rehoused optics) that change real-world performance. Environmental factors — temperature, humidity, optical adapters, and extender combinations — can all affect actual focal length, minimum object distance, and image quality in ways this tool cannot predict.
Use this calculator to narrow your lens options and plan your kit list. Confirm the shot with the actual glass on the actual camera before air.
This tool is provided "as is" without warranty of any kind, express or implied. We make no guarantees about the accuracy, completeness, or reliability of the calculations or lens data.
The developers and operators of Broadcast Lens Calculator assume no liability for decisions made based on this tool's output, including but not limited to equipment rental choices, crew deployments, or production outcomes.
Lens specifications in this tool are sourced from published manufacturer data sheets and verified where possible. However, manufacturers may update specifications, discontinue models, or produce lens variants with different characteristics. If you find an inaccuracy, please report it via email.
This tool is intended for professional broadcast production planning. Automated scraping, bulk data extraction, or systematic querying of the API is prohibited.
We may update these terms at any time. Continued use of the tool constitutes acceptance of any changes.
