its a lens made by sigma

if you are looking at one make sure you buy from someone who will let you return it
in the event that its not working right be wary of front and rear focus problems
(i have a 120-300mm2.8 that front focuses about 75mm in front of where im focusing)
and read as many reviews as poss
