That's funny. I shot a county track meet last Spring using a monopod & hood (more for slight drizzle than for sun). I kept hearing everyone whisper, "Look at that thing, he must be a pro." A few folks would move out of my way. Some others would try to block me. The coaches & the kids (and their mommas) loved the shots, though.
Unfortunately, the 70 on the 70-300 is too long for some shots, so I had to use my 18-200 on my D7000. Great for the closer shots, but not too good for the distant shots. Got the 18-300, and it is too soft for much of anything. Guess I'll be back to two cameras if I don't solve this problem. But, in track, like other sports you need to pan while shooting from over 100 meters to less than 10 meters or vice versa. This says I need a 10 plus zoom range. I would need a camera bearer for the Bigma.
