I am having trouble deciding what lens to pick up to add to my collection. For the past few days I have been dead set on getting the Sigma APO 70-300mm DG Macro since its one of the best 'bang for your buck'. I have also looked at the photo archive and have liked what I saw. However, the more I researched, I am not so sure anymore. Sports photography is what I intend to use the new lens for.
I have been trying to decide whether or not to get this Sigma or pay a few extra bones for the Canon equivalent. The only reason why I would get the Canon is for the autofocus. To me, that seems like it would be worth the extra coin. The problem with this though is that I have read that the build quality of the Canon is just as bad, if not worse than the 28-135mm lens I currently have. I think my best bet would be to pony up and get the 70-200 L non-IS. Yes, IS would be nice to have in sports I realize, but being that it is f4, I will be using it for day games, which I could get away with not having IS if my shutter speed is fast enough (?). With the L, I lose a bit of reach, but at least its f4. Plus, with any good lens it will hold its value and I can sell it when i am ready for a f2.8L.
The only thing holding me back from getting the 70-200 L is because I have other things I desperately need to get for my photography. I need a tripod and head which, I have a good idea on what I want to get (~$250). I would also like to get a flash as well as a few other things. All of this stuff adds up quick. Do I need a flash right now? Maybe not. I just don't know how to go about this.
I can go on and on about comparing and contrasting different lenses within my budget, but these seem to be the biggest contenders.
So to sum it up, I am not sure if I want to throw down 1k for pretty much just a lens, or get a less expensive lens and get other things to round out the camera. My gut tells me to get the tripod and other equipment. But my brain is saying don't invest in a less than adequate/quality glass.
Thanks for any help and direction. It is always welcome
