The big plus is that the colour fringes usually seen with achromatic lenses are completely absent with this lens. The individual lens elements are multi-coated, meaning you benefit from high light transmission and hence a bright image. \u003cbr data-mce-fragment=\"1\"\u003e\u003c\/p\u003e\n\u003cp data-mce-fragment=\"1\"\u003e\u003cb data-mce-fragment=\"1\"\u003eVery short construction\u003c\/b\u003e\u003c\/p\u003e\n\u003cp data-mce-fragment=\"1\"\u003eUse this Barlow where in particular where you need a shorter length.
