    Default Estimate the minimum distance...

    Hi all,
    I have 1 question regarding estimate distance, is there any way to estimate how much minimum distance that we need to have in order to capture object object (for example a row of 20 people) using certain focal length (example 28mm)? I just wondering because I think this is quite important (at least for me).

    I'm not sure how I do it, once I see the size of group, I can move to a position without second thought or lift up the camera, which the widest angle of my lens able to cover.

    maybe you just need more practice.

    Yeah, but still some triangles to calculate in order to get the distance as asked by TS.
