Hi everyone! Recently was thinking to get the tamron 17-50mm 2.8 and was already planning to go down to cathey to get it during the weekend when my friend asked me to help take photos during our graduation day. they were planning on going around singapore to take some photos, so this made me think should i still get the 17-50mm or should i get a wide angle lens instead? maybe the tokina 11-16 2.8? Further more i was thinking i might need a tripod as well since i intend to be in at least some of the pictures that is to be taken. I only have a budget of $1k. I've not actually been to any shop to ask how much the tokina 11-16 cost but looking at the price guide it costs $950 during dec 09 at OP (hoping price has dropped somewhat). the tamron 17-50 cost <$600 from what i checked.
So my question is:
Should i get the 17-50mm and spend 300+ on a carbon fibre tripod(heard the sirui isn't bad at all)
Should i get the 11-16mm and get the cheapest tripod i could get my hands on.
By the way i currently only own a D90 with the 18-105mm kit lens and my group of friends consits of 5 people.
