It was much darker than this photo makes it appear. (Photo is unprocessed other than downsizing). There was a family taking up the entire viewing area and when the one on the far end left to go to the other window I only had time to take one photo. It was too dark for the autofocus to lock, but this is where it stopped "searching" before I switched it to manual focus and it is a miracle that the ocelot actually is in focus.
To give you an idea of how dark it was, the ISO was set at 1600 and I had a large aperture lens set to f 1.6 and set the exposure compensation to minus 2/3 (giving me 2/3 stop faster shutter speed), and I still only had a shutter speed of 1/5 second! Good thing I was on a tripod and the ocelot did not move.
