I have no hand on experience with this exact Sigma model but my over all experience with ultra long range, zoom lenses has never been very good, in terms of IQ (Image Quality). Though convenience of the range of focal length and reach, especially for a traveler is very appealing. The problem with these lenses is usually over the last 25% or the tele side of focal length, especially when lens wide open.
Like to hear you experience with this lens, if you have already got it.
