Well, let me tell you what some of my intended applications are, and you make recommendations.
First, event photography. At the stage, at night, lots of lights, and I'm forward of the mosh pit trying to capture the whole stage in one image. But this won't be a common occurrence.
Second, general gatherings at parties, usually outdoors and usually in the daytime. This would include the occasional wedding.
Third, and I have this covered already with my long, fast focusing Tamzooka, photographing fast moving cars at racetracks. This should be great at airshows as well.
Fourth, I want to see what I can do in the way of photgraphing the night sky.
Fifth, wildlife at some distance, that being variable from feet to hundreds of feet.
I'll even stop to photograph bugs and plants but that's incidental and not a primary purpose.
I'm really not going to be doing much portrait work.
