    Default Why different aspect same focal length?

    Hi people,
    Seeking views of why two different cameras with similar setting has different picture coverage? I have a EPL5 with 14-42mm kit lens and LX5. I took picture at wide but the result is different, I thought oly 14mm = 28mm?
    Here are the pictures I took for reference. Thanks.



    I took another shot with LX5 at 50mm. It look similar to Oly 14mm wide?

    Please check the effective focal length of the LX5.

    I find it strange that the info on LX5 review will show f=28mm or f=50mm but EXIF is different? Why?

    The camera will tell u effective focal length for field of view reference I.e. 28mm, 50mm etc. But exif always shows lens focal length, which should be 6mm to ##mm after dividing by crop factor.

    And your first image of oly at 14mm, it really doesn't look 14mm (28mm effective). Double check again

    Your Olympus picture is definitely not with the lens set at 14mm.
