<p>I waited what seemed for forever for Nikon to produce a stabilized 300mm f/4, and just as I see they have finally come out with it ... they also introduce the 200-500 at an incredibly attractive price. So I'll go with the zoom as I need/want as much 'reach' as I can get. I have a Nikon 500mm f/4 and love it, but for travel it is a challenge as it requires a tripod, large carry bag, is hefty, etc. Also, it's minimum focus distance is approx 12 ft or so which is problematic for some subjects (e.g. a bird at 11 feet). To get a hand holdable Nikon 500mm lens with a min focus of 7 feet puts me in a position to easily bring the gear to other countries (or domestic hiking) with almost no hassle and get the image quality that has been shown in some early testing. Here's one of my favorite links, from a guy in Australia.<br>

So, I'm passing up what had been my previous dream travel lens (stabilized 300 f4) and going for the 500 zoom (hopefully with super fantastic firmware :).<br>
