Valid point.

 

I wanted a strong tele to shoot some sports, at first comes in my mind an event called "Bike Days Solothurn" (nearly 24.000 visitors, half of them photographers  ). Part of that is a fair, various races in the woods and some show events like MTB dirt jump. I like to catch the bikers when they are at 7...8 m high in the air from a closeby city wall. Distances soemwhat between 5 and 50 meters and it's difficult to access closer points to get that perspective.

 

Just because of this I would go with the zoom. In events where your position almost fixed the zoom is the tool. And since there will be not too much movement you can rest the weight on a tripod.

 

" Moon shots would be nice, too."

 

For this one you will need 600mm for sure.
