Picked up at 70-200 f2.8L IS today.. so will shortly be selling my 70-200 F4L IS.
anyway.. i haven't had time to take real world shots yet (pls don't flame me) but decided to do take a couple of focus test shots for interest's sake.. after all this lens is not cheap.
i found that focus was pretty much spot on.. and as expected, wide open at 200mm the lens was a lil soft.
but interesting thing I found was that contrast and sharpness seemed to be significantly better on the right side than the left side of the image at all focal lengths. Its really sharp in the middle though.
is this a common occurance?
Camera is a 5D2 so its full frame.
