Not Sharp, Not Matter What

Summary: Bought this from Amazon at the same time we bought the Sigma 10-20 super wide and the Canon 100MM Macro. Those two lenses are great, this one is a complete dog. Unfortunately, we have been so busy with the other two only recently have we had the need to use this one. The clarity is simply poor at all focal lengths and F stops. Does not matter if hand held, or on a tripod with a wireless flash, it's a dog.
Conclusion: Well made..well equipped with lens hood and tripod ring, the carry case is pure tinsel, who would lug this heavy lens about for so little reward.? Sorry Sigma but this lens is best forgotten...
Pros: None I could merit over the Canon 75-300mm 4-5.6 II USM it replaced
Cons: The 300/400mm 'reach' was a waste of time... softer than a babies butt. I bought the lens for the 'reach' - I should never had bothered.
