You can mark down 2019 as the year that mirrorless cameras vaulted to the top of photographers' wish lists. They sold nearly as well as DSLRs in 2018, thanks largely to Sony, and may outsell them for the first time in 2019. That's because the number available exploded at the end of 2018 and most of the important new cameras are mirrorless models. All of them have improved autofocus tech, better electronic viewfinders and excellent 4K video features. Nikon, Canon and Fujifilm are determined to cut into Sony's market share, so they all released new models -- to various degrees of critical acclaim. And it's working: Where Sony once had 99.5 percent of the full-frame mirrorless market in Japan, for instance, its share has dropped to 60 percent. More choice is terrific, but it does make your buying decision more difficult, which is why we're here. Our deep and detailed camera guide, dedicated to mirrorless models, will help you sort out which one that suits you best, depending on your needs and budget.
