Hi this is my first post and I just stumbled accross this fourm. I need your help but before we get to that here is some basic information on me. I have a Nikon D80 with two lens. I have a 18 to 70 and then the 70-300 IFVR. Both are Nikon lens. My experience on a scale of 1 to 10 is probably a 3. I tend to shoot all of my photographs in Auto mode. Two weeks ago I was out in SW WI and came across an eagle in a tree and now I find myself addicted to photographing them. My problem is my 300 lens didn't seem to be strong enough for me to get a close up pic. If I can figure out how to attach a photo I will. So back to the topic. I am looking for a stronger lens. In about 2 hours I will be going to pick up the Tamaron 200-500 lens. I tried to get the Sigma 150-500 lens but they didn't stock it and wanted me to pay up front for it with me only knowing it will be in within 2 weeks to 2 months. No thank you. I'm concerned though since I don't know the quality of these lens. Are they any good? I don't want to use a tele convertor since I am told I will lose my autofocus. So here are my options. 1) I could pick up the Nikon 200-400 VR lens which I believe is about $1800 but I am only really gaining the distance from 300-400. Sub Question - How much difference is there between 300 to 400 or 300 to 500? If a human body fills the whole picture at 300 how much closer will 400 or 500 get you? The camera place said I won't see a difference between 300-400 but if I go from 300-500 it's almost double. 2) I could get the Tamaron 200-500 lens. Concern of off brand and that it doesn't have VR. I do know I will need a tripod or mono pod regardless but I like the comfort of VR just since in my mind it could help the rookie. I could be way off on this. My other concern is the dealer was out of these for a long time since I am told Tamaron resdesigned the lens with a different motor. Do I need to be concerned on this? Lens is about $1,000. 3) I could get the Sigma 150-500 lens which has the built in VR but again concern of off brand. Lens is about $1000 4) I could get the 500 or 600 lens from Nikon but concerned that I am at a fixed length and I could be too close???? I was told these lens also cost about 10 grand and if that's the case there is no way I can afford that since I'm only a rookie and also have a D80. Thoughts? Advice? I will take my camera along when I go and look at the Tamaron and will find out their return policy in case I buy it and everyone here says to pass. Thanks for your time and help. Brian Edit: I see for a photo I need to paste a link to a website. All of my photos are on my pc. Can anyone recommend a good photo sharing site?
