I am still finding images to post from my backup files since we can not go out to even local parks here in NJ. These images are from a past trip years ago to J.N. Ding Darling National Wildlife Refuge in Florida. These were fairly far out in the water along the Wildlife Drive. I was using a Sigma 300 – 800mm f/5.6 zoom lens @ 800mm (The Sigmonster as it was called.) With Heavy Duty Gitzo tripod, Wimberly Gimbel Tripod head & Canon 1 Series Camera Body – total weight ~25 lbs. But once setup you could certainly work an area and get great images from subjects near & far.
