Sigma 10-20mm f/3.5 EX DC HSM ELD SLD Aspherical Super Wide Angle Lens for Canon Digital SLR Cameras - Starter Kit Includes a Filter Kit

howdy everyone today I'm look at another ultra wide-angle lens for aps-c cameras the Sigma 10 to 20 millimeter F 3.5 II X DC HSM it's one of the more expensive lenses in this market segment costing about 400 pounds or 560 US dollars but it ought to be a really nice product ultra wide-angle lenses are fun to use and handy this lenses zoom range ends at 20 millimeter which is quite a wide angle but zooms all the way out to 10 millimeter which is very wide indeed the full-frame equivalent of 16 millimeter that's wide enough for getting huge landscape vistas as well as capturing the whole image when you're shooting in large buildings it can also be useful for taking pictures in tight spaces 10 millimeter is a lot of fun so this lens has a nice enough zoom range and the ace up this lenses sleeve is it's reasonably fast constant maximum aperture of F three point five this lens can let in quit
