Imaging Resource has published their review of the SIGMA 18-250mm F3.5-6.3 DC OS HSM lens:

Like most ”vacation” zooms, the trick is to know the parameters where they function best. Sigma’s latest iteration of this lens offers a bit more telephoto performance, for which the integrated optical image stabilization is crucially useful. Unfortunately the lens’ maximum aperture decreases quickly as the lens is zoomed out, to the point where at 80mm, you’re using a ƒ/5.6 lens. This design allows the lens to be kept as small as it is, but at that point you’re needing either a sunny day, an external flash, or a steady hand (even with the image stabilization) to get reasonably sharp photos.
