    Yep, most macro lenses such as the 90 to 105 range from Sigma, Canon, Nikon and their ilk tend to have a designation like 1:1 in the description.

    This is normally based on a 35mm frame size, for cropped sensors the magnification is greater.

      Actually for cropped sensors it’ll still be 1:1 but “cropped”

      You can get more magnification if you use extension tubes or specialized lenses.
