It offers much of the capability of the EOS-1D X III in an enthusiast-level mirrorless body. It's only a 20MP camera but one that can produce great results across a huge range of photographic challenges. The tendency to overheat if used before shooting video undermines its appeal for people shooting video and stills together.
It might be the mirrorless alternative to the very popular EOS 6D Mark II DSLR, but it’s way more than just an upgrade. Its autofocus performance and image stabilization are best-in-class, while a blitzing burst speed makes it perfect for any sports or wildlife scenario. Long story short, it’s one of the best all-rounders you can get, although its 20MP sensor resolution might not suit everyone.
