Photo By Dutch Dyer “The cold morning air in Bojanala can make you hunt those warm rays of South African sunshine just to break the chill,” explains Dutch Dyer. “Several hours into a guided photo safari in the Pilanesberg Game Reserve, we had been on the hunt for some of that sunshine along with what locals call the ‘Big 5’—buffalo, elephant, leopard, lion and rhino. My ear-to-ear smile was some indication of how the day was going. I had also captured shots of hyenas, wild dogs and hippos, but I had yet to add a giraffe to that list. “We stopped for lunch close to a water source. In the arid African grassland, water is the universal lure, and I didn’t have to wait long. I could see two giraffes approaching in the distance, and I moved into position. The young giraffe in this shot drank its fill while the other one kept watch for predators. Raising its head, the giraffe looked my way and used its long tongue to catch the last drops of water. I laughed out loud.” See more of Dutch D...

The Sony Alpha 1 features a new 50.1-megapixel full-frame stacked image sensor. Sony today introduced the Alpha 1, the new flagship camera of its full-frame mirrorless system. The Alpha 1 includes several benchmark-setting improvements over the company’s previous flagship, the a9 II, that make it an incredibly powerful camera for both landscape and wildlife photography. The Alpha 1 features a new 50.1-megapixel full-frame stacked image sensor that Sony states is capable of 15 stops dynamic range for stills and even greater range (“15+”) for video. That makes it the highest resolution full-frame mirrorless camera to date. Top view of the Sony Alpha 1. It can capture stills at up to 30 fps, totally blackout-free, meaning there’s no interruption to the viewfinder image while shooting. The viewfinder is noteworthy, too, with the fastest refresh rate of any EVF at 240 fps. The camera offers both a mechanical and electronic shutter, and the 30 fps continuous capture rate is available...
