Lost Camera Prospect Park

I may have lost my Sony Nex 5N camera (with a 30 mm Sigma lens on it) in a small black Lowepro camera bag (the camera was in a gray rag wool sock within the bag) today at Prospect Park around 4 p.m. Embedded below is a map with the likeliest area in yellow; the only places I went are in red, so it could be there too.

There are no photos on it; it was new to me, bought used just this week (so it won't look 100 percent new). It is possible it was pinched from my bag at another point—I am trying to cover all my bases.

This is obviously a long shot. There is a definitely a cash reward!

Thanks!
