Life-size close-ups can be taken from a farther distance without disturbing the subject (insects, etc ...)
Another telephoto macro lens with a maximum magnification of 1x. Life-size close-ups can be taken from a farther distance without disturbing the subject (insects, etc). The internal floating system minimizes fluctuations in aberrations caused by changes in the focusing distance. The delineation is therefore razor sharp from 1x to infinity.
