  • Sigma 80-400mm f/4.5-5.6 EX DG OS APO

    8 out of 10 points and recommended
    It' has good colour
    It's heavy

    The only drawbacks for me are that the focus motor is very noisy (but it is reasonably fast- things don't snap into focus immediately, but if you're able to pre-focus into the region where you know your subject will be, or use your camera's continuous focus tracking mode and follow the subject, this lens is quite usable for action/sports). For some reason, turning on the OS makes the focus motor even noisier: the OS itself is very quiet, about the same as the Nikon VR, but you get some additional noises when the OS kicks in: first, there's a whine/buzz as the moving element unlocks, then you get the expected quiet 'hissing" of the OS. While the OS is active, the focus motor seems to be much louder in operation than when it is turned off and then when you've taken the shot and have let go of the shutter button, after a second, there's another buzz/whine as the moving element locks in place again. Due to this and the physical size, you are quite conspicuous when using this lens, and it is probably not ideal for wildlife photography or in situations where the noise might be distracting.
