Focal Finder Customer Insights

1. Useful to explore other f lengths to make composition choices.Just what I needed, I use this app mainly to help me frame in combination with vintage rangefinder cameras which have interchangeable lenses.

2. I'll bump it up to 5* when a 4:5 aspect ratio and automatic rotation for portrait mode is added.Useful app to visualise different lens field of view.

3. I wish I could enter a 35mm equivalent number manually (and persist that setting) rather than dragging a slider, but this works very well already.

4. Just wish that custom aspect ratio is available.

5. Multiple frame lines and ability to change the FoV in which they're embedded.

6. Not sure why this app is rated so lowIt has hung a couple of times, but otherwise works well.

7. I managed to calibrate it and compare with my camera.

8. Quite good for location scouting too.Good app.

10. Exactly what I was looking for.
