I really wanted to step into the L series of Canon lens', however photography is not my profession so justifying the money for this type of lens was tough. I chose this because it was the most affordable L series. It does not have image stabilization, but oh well. You really only need IS for inside shots requiring more light, portrait shots. This lens is designed for action shots and I use it to take pictures riding big mountain (skiing). The price difference between this lens and the EF 70-300 F/4L IS is about $700. So it was a perfect fit. It is one solid piece and is top quality. I would highly recommend, if owning a DSLR camera to have an L series lens in your bag of tricks. You do not have to have a Full Frame camera to get amazing shots, you just need an amazing lens!
