So what’s so good about the Sony a7 III? Let’s start with the heart of every full frame camera – the sensor. More importantly, both of the other recommended Sony full frame cameras are much more expensive than this one! Both of them offer certain features that the Sony a7 III does not, but these features only appeal to a very small number of photographers. You’ll see 2 other Sony mirrorless cameras below in this list of the best full frame cameras of the year. The Sony a7 III is a strange beast, eating into not only the established DSLR-owner market but also cannibalizing sales of Sony’s more expensive offerings. While the other big camera manufacturers choose to release updated versions of their full frame camera models every few years, Sony seems to rush out its releases every year, often to the confusion/delight of consumers. Sony has made a name for itself for fast-moving innovation in the mirrorless camera market, and with the Sony a7 III, its position has been cemented as a major competitor to Canon and Nikon, set to disrupt DSLR sales worldwide. Oh Sony, what did you do to the camera market in 2018?! I can’t remember a camera release that piqued so much interest as the incredible Sony a7 III.
