Quality results partnered with the speedy operation - The original A7 and A7 II showed Sony was moving in the right direction and making all the right noises. The new A7 models are the third generation of Sony's professional mirrorless line, so their main features are well known at this point. But just to recap: these are professional-level cameras with full-frame image sensors that are significantly smaller and lighter than comparably equipped DSLRs from Canon or Nikon. But despite being over 18 months old, it's this third iteration that still stands out in the full-frame mirrorless market. The core of the camera – namely a 24MP full-frame sensor, 4K video, sensor-based image stabilisation, 10fps burst shooting and a 693-point hybrid AF system – is strong enough, but with two card slots and a 710-shot battery life on top of that, you're getting excellent value for money as well as top performance. We have some reservations with the viewfinder and weather-sealing, but this is still one of the most versatile cameras around right now, mirrorless or otherwise.
