In a post about switching to Sony, LensRentals' Zach Sutton discusses the details of the Sony system from lenses to hot shoes to system size and weight. Ultimately, it's Sony's technology that he finds to be the most compelling reason to migrate away from the DSLR.

"The number one reason for you to consider switching to Sony is that it’s primarily from the future. The tech within the systems is so incredibly far ahead of Canon and Nikon, giving you more power to do what you love. For one, the digital viewfinder feels cutting edge, giving you exposure and depth of field in (virtually) real time. For those who grew up on DSLRs, and especially those who started on film, this feels like cheating. Quite simply, that battery draining viewfinder will, without question, make photography easier for everyone who uses it. Additionally, something like the Sony α7R II has wifi, 399 focus points, 4K video capabilities, 5-axis internal image stabilization, and a beautifully crafted full frame 42mp sensor. Virtually everything you would need, and didn’t know you wanted is available in a mirrorless system, making your bulk DSLR feel like a relic from another, much older era in comparison." -Zach Sutton, LensRentals Blog
