This was my absolute go to lens for quite a while until I got the Sony Zeiss 28-70. Having said that I still used it a lot because it light compared with the Zeiss and for most general point and shoot photographs the Sigma was just as good. its a fantastic little, light, versatile lens. It is a F2.8 lens which means its a full stop brighter that the usual 28-70 kit lenses so you can work in lower light or the same light with a faster shutter speed The lens is in good condition optics wise, with no scratches, burrs or mould however my fingers have worn the coating off the barrel and hood (as shown) in some small bits (shows how much I liked it!)
