<p>That particular lens? No. But in general terms, it's a close-up lens (or filter, since it screws in like a filter). This is a 2x diopter, which means it focuses at 1/2 meter when the main lens is focused at infinity. It has a double (i.e., achromatic) group, which means the optical quality is better than the more typical single element version.</p>

<p>If you can't change lenses, hence use a true macro lens or extension rings, this is your only option for shooting closer than the minimum focusing distance without the adapter.</p>
