This is an awesome lens, but it is much bigger and heavier than I anticipated, hence only 4 stars. I have a Sigma Bigma and this lens is only slightly smaller. I have only taken maybe 50 photos with it and it autofocuses immediately, is very quiet and the pictures turned out great as they were crisp and clear. One thing was also immediately apparent was that the depth of field is quite small. An example I took a picture of my dog in my kitchen 6 feet away and everything immediately behind her was blurred. She on the other hand popped out of the picture. Pictures taken at a greater distance cut this effect drastically. I saw in another review that Canon wouldnt honor his rebate. I am hoping that isnt the case with mine. The rebate was for $100 off if purchased between March 2, 2014 and March 29, 2014. I bought mine on March 6th, so we will see. Since receiving this lens I have since purchased a Joby carrying strap as even my Tamron 28mm - 300mm stresses my neck after a bit and the Canon lens is at least 2+ times heavier. I will review that product in conjunction with this lens when I have had an opportunity to utilize both together (supposed to get the strap tomorrow).
