I'll be attending my friends indoor, banquet hall wedding in a few weeks and I wanted to rent a sharp lens. I tend to spend most of my time at friends weddings (and parties, and everything else) taking pictures. I currently have a Nikon D90, 50mm 1.8, and the 18-200 VR. The 18-200 is a very versatile lens but isn't very sharp. So I've decided these are the two contenders for renting: Nikon 70-200mm f/2.8 AF-S VR ($91) Tamron 70-200mm f/2.8 ($49) The rental price isn't an issue, but if I decided I really loved shooting with a 70-200 2.8, I'd buy the Tamron (I found it for $670), but the Nikon is way to pricey for me ($1800). So the question is, do you think it's worth it having the higher quality Nikon to shoot with that day, or going with the Tamron which I'm more likely to purchase. edit: Actually, while re-reading this before submitting, I think I answered my own question. I think I'm going to rent the Nikon and if I really enjoyed it, just rent the Tamron and play around with it to see how it matches up, then buy one if I like that as well. But still curious on others thoughts.
