The new Tokina AT-X 165 PRO DX makes an excellent standard lens. It gives the digital photographer the equivalent of a 24-75mm lens in terms of film. Every photographer from the nature enthusiast to the portrait artist to photojournalist, everyone will be able to appreciate the AT-X 165's bright F/2.8 constant aperture. This wide aperture allows for faster shutter speeds in low-light conditions or a more shallow depth of field for more pleasing portraits. The out of focus background from a wide aperture setting concentrates attention on the subject giving the photo more strength and intimacy.
