I would second (or third!) the advice regarding Vivitar Series 1. I would add that if it is not a Series 1, it is kind of high. Check out KEH, http://www.keh.com, to see what they offer. They have great prices and I have always been happy with their service. They currently have Nikon zooms in that range for a similar price. Just make sure you get the AI version for your F3. They also have a Vivitar Series 1 70-210 for about $50 and a non Series 1 80-200 for $15!
