## 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.
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.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:
```
GET https://support.senterasensors.com/home/65r-sensor-user-guide/65r-sensor/variants.md?ask=&goal=
```
`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.
The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.
Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
