A camera lens is an incredibly important accessory for all photographers because it can enhance and alter a photo in the exact way in which you want. Typically lenses help to control the range of a shot, the depth of field, the contrast and the quality of the shot. The Sigma 70-300mm is a perfect choice for long range photographers that need to capture shots that they can't get close to.
The 70-300mm zoom refers to the possible focal length of the camera. The focal length is the distance between the center of its lense and its focus, meaning how far away you can capture photographs and remain in focus. The 70-300mm lens option provides the user with a very large range and focal length, allowing photographers to get much closer to a shot with the help of the zoom.
This lens is also particularly useful for micro photography. This is the art of capturing an image larger than life scale size. A good example would be an image of an ants face, this would be much larger than the life size scale of the ant itself. This is a useful addition to nature photographers portfolio's and it is useful for amatuer photographers looking to gain a new skill.
