Tokina AT-X 80-400mm f4.5-5.6

     This lens needed some TLC and thankfully it was accessible and cleanable.

     My copy has a Nikkor AF-D mount.   Using it on my Eos 6D makes it necessary to manually focus which is doable but not preferred for quick shots..  It does not have vibration reduction, but it is the 2nd version with the tripod collar.    Shooting without the collar at 400mm would be quite difficult.   The collar does interfere a .little with the zoom ring though.    It is an AT-X model so it is built like a tank and it is no longer than a 70-300mm lens.

     I have taken a few pics with it.    I can say that it peforms very well from 80 to 300mm.  300 to 400mm is a different story.   It's as if there are two different lenses with two different sets of characteristics existing in one lens body.   If you use it as an 80-300 you will be quite pleased with it.  Beyond 300mm you must stop down to f8 or f11 to correct for abberations.     
     Overall it is a very good lens for an amateur who wants to step up from the average 70-300 lens.    On the used market it is very atttractive.
