Putting Sony to the testRed Bull Illume partner Sony recently sent us two of their cameras – the A7R Mark II and RX10 Mark II – and asked us to put them to the test. So we set out to do just that. 07/07/2016 From studio shoots and an indoor BMX contest to snowboarding action sequences high up in the mountains, we sent the A7R Mark II and RX10 Mark II into a bunch of different conditions. Here’s how they performed:Sony A7R Mark IISony’s flagship stills photography cameraThis mirrorless camera’s greatest asset is its full-frame sensor with 42MP and almost 400AF points. It also happens to be splash and dust-proof, so it holds its own in rougher conditions. While this isn’t the camera you’ll pack for an Arctic expedition, it will survive a thunderstorm. Thanks to 5-axis stabilization, even handheld shots with slower shutter speeds look as if they could have been shot using a tripod. When shooting at slow speeds, this is a feature that comes in real handy. Pros: - 42MPs! - 399 Auto Focus points- Very good image quality- Dynamic Range- Super fast autofocus with native lenses- Light, compact cameraCons:- When using a lens adapter, focus points drop to 15- High-capacity, high-speed storage card required- Menu could be more user-friendly- Battery life could be better (carry extra packs)Sony RX10 Mark IIThe Sony A7R M II’s little brotherThis feature-packed and compact point-and-shoot camera is an excellent option, because of its ability to shoot 4K as well as slow motion. The built-in 24-200mm lens is a very capable all-round lens with a constant f/2.8 aperture. It’s a quick shooter too, offering 14fps during continuous shooting and up to 960fps when in video mode. In short then: Pros:- Great all-rounder- Very good image quality - Bright constant 2.8 max aperture- Light, compact bodyCons: - Battery life could be better- Menu could be more user-friendly- Requires high-capacity, high-speed storage card to use 4K and slow motion The image quality of both cameras are excellent, making them ideal companions for technical / artistic photographers. Just remember to carry those extra battery packs and speedy storage cards.Find out more about the Sony A7R Mark II and RX10 Mark II on their website.Keep visiting redbullillume.com for your weekly dose of action and adventure sports photography and galleries of inspirational images.
