Topic camera shake: In general, the inverse of the focal length should be at least the selected shutter speed corresponding to that at 200mm focal length one should choose a shutter speed of at least 1 / 200s or faster. Otherwise camera shake are favored and you should then use a tripod.
But whoever seeks, like me, so that moving objects (in my example: horses) to photograph the remains, so that the movement can be frozen, usually at 1 / 500s or faster shutter speed.
This lens is also not very suitable for indoor use. The environment should always be well-lit. Otherwise the shutter speed is too long and you are fighting back with camera shake.
Very sharp lens is not well. Who but eh only makes images for web and computer / desktop background, will certainly be satisfied with this lens.
I recommend anyone who wants to buy this Tele to inform in advance what you need to consider when purchasing lens. If this is done, and then decide not aware because of the price for this lens, each will have his pleasure.
