I have the Tamron 70-300mm lens. It isn't image stabilized so I have to use a tripod with it, but it takes really nice images. I really like all the interesting shapes and textures in your shot. My eye is drawn more to the rope than to the cute little birds waiting for their meal to arrive.
Cheap lens? Maybe; but a fine result, especially at full zoom! I like the colors in this shot, and the textures and detail are great. Nicely done, Richie!
