comment:I was looking for a lightweight, long reach telephoto lens that can be easily be carried around, at a very affordable price.... this lens delivered! It can be hand held easy but you need good light and high ISO (400 to 800), a tripod collar mount would have been great to have. I would not use this lens for birds or wild animals, it is not sharp enough and focus creeps to much, but for general purpose it's excellent, that's why I gave it a 4.5 on sharpness. Colors is another story, older Minolta coating I presume is the problem, but nothing that cannot be fix in Camera RAW. If you are not a serious wildlife photographer looking for that perfect “National Geographic” shoot.... then go for it, because the next step in sharpness are all the G telephoto lens, and THEY are expensive!
