You can take pictures from wide angle all the way out to ultra telephoto by using the built-in zoom control. When in the 35mm format, it can cover views from 28mm to 419 mm. It comes with its own optical stabilization technology, the tri-axial Vibration Compensation. The weight for this one is 19.8 ounces, and the filter size is 72mm.
It can be used with specially Canon and Nikon mounts, and you can zoom out to a 15x zoom ratio. This lens was made to be strictly used with SLR cameras that have an APS-C sized senor. And, the images that you will capture with this lens are phenomenal.
