Ok, I have a kid on the way and most of my paycheck went to baby stuff. I'd love to get a 70-200mm vr for my nikon d80 for mostly lowlight indoor pics and right now, Can't justify spending $1800 on it just yet. Anyone know of other alternatives to this that could do indoor shots at 2.8f? I currently own an 18-200 vr and 50mm 1.8, but would love to have a telephoto zoom that does 2.8f all the way. Nikon, sigma, tamron... it doesn't matter to me as long as it's fairly inexpensive (compared to VR) and does the job under low light situations. thanks in advance!
