Title: Worst lenses ever
Review: well the question of is this an ok lens yes and no. i did 3 events where i needed long focal length and this thing crapped out on me at 300mm/ no flash/ iso 6400/ at f5.6 - 1/150 which gives super blurry pics... and don't think of moving the shutter speed this thing looses so much light. but ok i tried it outside in sunny conditions, well it was super dark as well shooting RAW, adjusting exposure in post shows to much grain for an outdoor picture... in all i was not pleased with this lens and opted for the 70-200mm f2.8 yes it is worth the 2k price but you get what you pay for...when it comes to a lens on't be cheap or you won't be happy....
