I bought this lens to complete my small range of amateur photographer and I emphasize the word "amateur" because I think this goal is for enthusiasts who want to take photos without pretension. It has no stabilizer but I did not notice any difference from pictures I took with the EF-S 18-55mm even up to 300mm without a tripod despite some reviews saying it would a tripod at maximum zoom.
In summary, this is a good target for the price but if you have no balance or Parkinson then prefer the more expensive version that has a stabilizer.
