I have a 100 f2.8 IS macro lens as my main macro lens (it's AMAZING) but it fell off at a wedding and I had to send it in to have it fixed I needed one different macro and FAST. I ordered it to shoot before 100 macro was available and it didn't disappoint. Obviously it doesn't compare to the 100 f2.8 IS in terms of clarity/sharpness, but this thing gets the job done and I think I'll stick with it because it's a very handy backup for the 100. Overall I am definitely satisfied lens, CONSIDERING THE PRICE. If you're a professional photographer, get the 100 if you're just looking to get into macro photography or can't afford the 100 but want to add a macro lens to your gear bag. this thing will do the job!
