Greer, my friend ... buy the lens. You won't be disappointed. I'm 74 years old and have been toting heavier long lenses around for over 30 years. Well, to boot, I'm disabled with MS and racked with unforgiving arthritis ............. and, I love my Nikon 200-500mm lens! Too heavy? Give me a break ... 'it comes with the territory'. The too heavy excuse doesn't cut it with me!
Having gone from serious amateur to semi-pro to pro photographer, I've packed around a lot of 'Fast Glass' lenses. Yes, these lenses do produce some sharper images, yet, even though I could afford it, I gave up trying to 'keep up with the Jone's' of the photo world. Much less trying to impress anyone, especially fellow shooters. Having shot next to 'Top Guns' from Time, Life, and other rival publications, my slower and un-impressive lenses compared to theirs did the jobs just fine!
You might be new to photography, and if so, always remember ... it's not the camera that creates the picture, but the person behind the camera. You don't need a high-dollar piece of 'Fast Glass' to take stunning photographs.
I'm partial to Nikon gear, don't get paid to endorse or promote their stuff, but I graduated to it and I truly love it. And, I just don't understand why folks continue to screw cheaper, lesser costing glass different make glass in front of their Nikons, Cannons, Sony's, just for the sake of pinching a few bucks or getting some smok'n deal. Then, the next thing they do in short order is to put the thing up or sale for what-ever reasons.
So, have a look at these images some of these SM'ers have posted to your question ... have a peek at a bunch more images people are getting with this lens. Nikon made a keeper for me with the 20-500 f/5.6 and depending on the photo subjects I strap on a Nikkor TC 1.7 III for 750mm @ f/8. If I really want to 'reach out and touch someone, the DX mode produces 1050mm. I love the results with all three.
