Description
Key Features:
From 24mm super wide angle to 70mm medium telephoto, this lens provides a large f2.8 aperture at all focal lengths. This lens incorporates Super Multi Layer Coating to reduce the influence of harmful light caused by reflections from the digital image sensor.
Two SLD elements, one Glass Mold Aspherical plus two Hybrid Aspherical lenses provide excellent correction of various aberrations and a high level of optical performance. The lens has a minimum focusing distance of 40cm (15.7 inches) at all focal lengths and is capable of macro photography with a maximum magnification ratio of 1:3.8. It also incorporates a Dual Focus (DF) system that is designed to make the lens easy to hold during autofocusing, and yet provides a large focus ring for easy manual focusing. Since the front of the lens does not rotate, a Petal-type hood and circular polarizing filters can be easily used.
Specifications:
- Maximum aperture f2.8
- Two special Low Dispersion glass elements
- 3 Aspherical lenses
- Dual focus system
