An incredibly small and light 28-300mm zoom lens with a constant minimum focus distance and a high maximum magnification of 1:2.9. The remarkable achievements are brought about through XR (extra refractive index) glass and efficient use of aspherical lenses. Size is reduced 25%, weight 27% and filter diameter was decreased from 72mm to 62mm. Excellent optical performance. A maximum reproduction ratio of 1:2.9 at the 300mm setting (and a minimum focusing distance of just 19 inches at all focal lengths). Use of Extra Refractive Index glass?the "XR" in the lens' name?helps produce a smaller, sharper lens. A nine-blade diaphragm yields pleasantly blurred backgrounds for portrait and macro subjects. A Zoom Lock keeps the lens at it shortest physical length for easy carrying. The attractive high-quality pearl-black finish makes for a very attractive piece. And an included flower-shaped lens hood provides vignetting-free flare protection.
