Everything is relative: interchangeable lenses for cameras from third-party manufacturersLenses from alternative brands: money down the drain or an increase in image quality?

Short description:

The standard macro lens is equipped with a floating focus mechanism and allows you to take high-quality life-size pictures of miniature objects, as well as shoot long shots. The excellent optical performance makes this lens suitable for use with digital single-lens reflex cameras. The lens successfully suppresses magnification chromatic aberration, which is especially prone to the optical systems of digital cameras, as well as other types of aberration, both in the central part of the image and at the periphery. The lens is equipped with a round lens hood with a threaded connection; it is also possible to use circular polarizing filters. The minimum lens aperture - F45 (for Nikon and Pentax cameras - F32) provides a large depth of field.
