Feature: 1. The 60mm / 2.4in F2.8 II uses an internal focusing design that does not change the length of the lens in use and does not rotate the front lens group, facilitating the use of polarizers and special effect filters. 2. With F2.8 maximum aperture, compact and exquisite, stable, easy to carry, higher magnification, greater depth of field. And it can also reduce the turning moment of the lens drive and maintain a stable sense of focusing. 3. At magnification of 1:1, more detail can be obtained. Both infinite and 1:1 magnification can get clear image, 0.175m / 6.9in focusing distance, can get more fill light range. 4. With 9 aperture blades, it has softer blur effect. In macro photography, a linear contrast between imaginary and real is obtained by using the delexicalization of large aperture to form a sense of increasing hierarchy. 5. Built in ED (ultra low dispersion lens) is optimally configured to effectively suppress aberration, reduce dispersion and provide clear and transparent images.
