About this product
Product Information
The Tamron SP 500mm is a lightweight, compact 500mm ultra telephoto lens featuring a mirror-type optical system. If you're not familiar with them, mirror lenses use a pair of shaped mirrors to bounce light back and forth within the lens. This, combined with other optical elements, allows a long effective focal length in a compact space. As a result, mirror lenses are small and lightweight despite their powerful focusing power. Although its reach is exceptional, the Tamron is about the length and weight of a mid-range telephoto in a standard design.The Tamron SP 500mm uses seven elements, including the two mirrors, in four groups. The rear element surface features a silver evaporation coating to compensate for spherical aberrations on the reflective surface. As a result, the Tamron produces high-quality images throughout the focusing range. In addition, you'll find that mirror lenses produce an unusual style of bokeh, the aesthetic quality of blur in the out-of-focus highlights of the image. The circular bokeh highlights result from the front or secondary mirror, which blocks the central part of the lens opening. In addition to creating unusual bokeh, the mirrors tend to lower the contrast in photos. If you prefer more intense contrast, this can be easily corrected in your photo using any imaging processing program.The Tamron SP 500mm has continuous focusing from infinity to macro range. At the macro range, the lens has a 1:3 maximum magnification ratio at 1.7 meters. The Tamron SP 500mm has a fixed aperture at f/8. This means that you have to control the exposure through changes in shutter speed or by adjusting the ISO. This aperture feature makes the lens ideal for outdoor photography and long-distance shots. If you are dealing with too much light, you can use a rear filter accessory, which screws onto the end of the rear group at the mount end. That rear filter can also be used for other purposes such as color correction.The Tamron is strictly a manual focus lens due to its lack of electronic components. One of the real positives of a Tamron lens is that Tamron Adaptall mounts can fit nearly any film or digital camera from major brands like Canon, Sony, and Nikon. That means this lens has a wide range of possible applications to be compatible with multiple cameras that you already own.The small physical size and modest weight of the mirror lens mean that it is possible to hold the camera while taking photos if a tripod is not available. It offers an appropriately fast shutter speed with excellent results. This is a 500mm lens, equivalent to 800mm on an APS-C sensor, so shooting with a tripod or monopod lets you take your shots with perfect ease. Its smaller size also makes it more discreet if you happen to be using it for nature photography and don't want to disturb any creatures. The lens weighs less than 2 pounds and is easy to balance with the camera body of your choice.Product Identifiers
