Lenses for less than $500 that have Panasonic O.I.S. image stabilization, have a generic focus motor, have a 100mm or longer focal length and have a f/4 or faster aperture
"Very quick focus and keeping in mind this is a low cost lens that gives decent image results that compare well with its price point. Very happy with it for those times I need that extra reach. Out of focus bokeh is also quite nice." bhphotovideo.com
