Hi, the Views and Maps integration doesn't currently offer a filter that responds to zoom level or the visible map area. We do offer a distance filter, but it's not exactly the same. You can filter by distance from a specific point, or by distance from the User's current location (HTTPS only). Very soon (within the next week or so) a new update for Maps will be released that allows you to filter by distance from an arbitrary location, which may also be useful. However, filtering by the visible area is not planned for this upcoming release. If you'd like to see this feature added, I encourage you submit a new ticket here in the forum using the "Suggest an improvement" option. Our development team will review the request and let you know if it is something we can implement.
