    Sigma fine tune using the Doc.

    Ok I'm a little confused on how to tune my sigma.
    I'm trying to tune it, it is sharp when it focuses at .3 meters .4 meters and .6 meters
    But when the subject is at say .3 meters the focus scale on the lens does not read .3 meters.
    Is that a problem. It's like this all the way through the focus range.
    Is that normal?

    you must be busy. I'm thinking you're talking about the little distance scale in the window on the top of the lens doesn't match your measurement of the distance to the focus target?

    if so, how are you measuring? how far off is the meter on the lens?

    Ok here I am, let me set this up for you. I have the Lenscal .99 ft. From the end of the lens and this is the distance scale on the sigma.

    Check that out and let me know if I'm doing it wrong.

    ah that's probably why, you don't measure from the end of the lens, you measure from the sensor inside the camera. that's why the scale shows it closer to 1.5 feet.

    yeah, there should be a mark somewhere that looks like a circle with a line through it. that's where the sensor plane is, im not sure about the D600 but on my 800E its up next to the top LCD screen
