|Highly practical and portable telephoto zoom lens. The five zoom groups make the length only 4.8 in. (121.5mm). With rear focusing, the lens does not change length or rotate during focusing. Any filter effects therefore remain intact. It also makes autofocusing quick and quiet.|
High-performance 3x telephoto zoom lens. Synthetic fluorite in group 1 and UD glass in group 2 achieve low refraction and low dispersion. They also effectively correct chromatic and other aberrations. Resolution is high throughout all focal lengths. Images are sharp and crisp. At the 300mm focal length, 0.25x magnification is possible.
