Sigma 10-20mm F/4-5.6 DC EX HSM Autofocus Lens For Nikon APS-C Sensor DSLRS {77} Description


This series of zoom lenses was created to give a lightweight lens that could be wide angle or telephoto or in-between. The focal length rules still apply to zoom lenses. The focal length is for the format the lens was designed for.  This focal length is based on 35mm full-frame cameras or digital full-frame cameras. An SLR that uses a lens such as DX or APS-C most be multiplied by a factor to see the actual focal length that comes from using a sensor that is smaller than 24x36 size. If the lens is used with a full-frame SLR, the first number is the widest angle, the second the maximum focal length. If the second is less than 50mm, then it is a wide-angle zoom. If it goes higher than 50mm, it is a wide-angle to telephoto zoom. If the base maximum f/stop is a fixed number, the f/stop range will remain constant throughout the zoom range. If this number is two part, such as f/2.8-f/4, then the lens will only be an f/2.8 lens at the smallest millimeter. This will vary throughout the zoom range and will end at the maximum telephoto at the second f/stop. With a camera that meters through the lens, this change will be automatically adjusted. If you are using a flash that is not coupled to the meter, you must adjust the f/stop to compensate 

It's important to have a high quality ultra-wide angle zoom in a lens kit. Sigma's 10-20mm F4-5.6 EX DC ultra-wide zoom lens for digital SLR cameras is ideal for landscape photography, building interiors, group and party pictures and so much more. Great for working with close foreground subjects as this lens features a minimum focusing distance of 9.4" at all focal lengths ensuring great creative potential. The wide angle view of up to 102? also offers greater freedom of expression.
