Lens is really good and the focus is really great. I took some of the flower and bird photos and it came out very gud. Macro lens is really works better then i expected. I did not like the quality off HD 2x converter as i am getting more light in the image and the image is not clear. Over all i really liked the lens and its not too heavy.
The lightest 4x telephoto zoom lens in its class. Ideal for sports, portraiture, animals, etc. The telephoto effect can make the picture look compressed or have excellent background blur. At the 300mm focal length, you can fill the frame with a postcard from 4.9' away.
