    You get closer subject to lens distance, so the subject will be bigger.

    Close up filter is like magnifying glass.

    Closeup filter is mainly for non-dedicated macro lens. Meaning there is no different if you use
    - 100mm f2 with +2 closeup filter
    - 100mm f2.8 macro with +2 closeup filter
    - 70-200mm f2.8 @100mm with +2 closeup filter
    - 100-400mm @ 100mm with +2 closeup filter
    - 70-300mm @ 100mm with +2 closeup filter

    all above setup will give the same or similar magnification.

    It's the same if the subject distance is the same. But some of these lens can focus closer then others. The closer the lens can focus, the higher the magnification you are achieve.

    Yes you can but at 100mmwith +2 closeup filter, the magnification is not a lot.

    Using a close-up filter,

    focusing distance depend on the diopter value of the close up,
    e.g.
    +2, focusing distance is about 0.5m
    +4, focusing distance is about 0.25m

    magnification depend on the diopter value and focal length of the lens,
    see the list of the canon lens with 250D, 500D and 12mm/25mm ext. tube table at
    http://www.bobatkins.com/photography/eosfaq/closeup.htm

    Summary, if you want big magnification for macro photography, try longer focal length like 200mm or longer with +2 or +4 closeup filter.

    Even the lens can focus closer, the focusing distance will be limited by the diopter value when using a close-up filter.

    e.g.
    - 100mm with +2 closeup filter
    - 200mm with +2 closeup filter
    - 300mm with +2 closeup filter
    - 400mm with +2 closeup filter
    - 500mm with +2 closeup filter

    all above will have similar or same focusing distance but magnification increase for longer focal length.

    I see... thanks!

    Does it mean that when you use the Close Up Filter (e.g. 4T or 3T or 250D or 500D), you have to use Manual Focus? e.g. Moving close to the object and moving your lens slowly away from the object until focuses?

    Or can we still use Auto Focus?

    Usually when I do macro, I do manual focus. E.g. Moving close to the object and moving your lens slowly away from the object until focuses.

    Not really have to use manual focus but recommend to use.

    Why use manual focus?

    - When lens focus in short/close-up range, the auto focus tend to hunt a lot.

    - Manual focus can adjust magnification or frame the shots by manually turn the focusing ring. To achieve the max. magnification, you need to set the min. focusing distance.
