A standout among medium telephoto lenses due to its
large maximum aperture and 3 ED glass elements that
compensate for chromatic aberration. Demonstrates
high resolving power even at wider apertures and also
sharpness from corner to corner, which allows for subtle
details to be captured faithfully. Another key benefit is the
powerful close-up capability, as 0.25x magnification can
be obtained with high image quality at the lens’ minimum
