Hi there, I currently have a Nikon D3100, I'm still on a college budget and only have a Tamron 70-300 4.5f telephoto lens for the sporting matches I have to shoot. It gets the job done but I need a faster body. I'm really looking at the D2X, it has a faster shutter then my D3100 and its right around my budget. I've heard stories though that the Tamron lenses may not come out clear with the old style body. Is this true? If there is a better alternative body I would love to hear suggestions. Thanks
