“Like the RX1, the a7s aren’t without their faults, namely a poor autofocus system, poor battery life, still fairly high price tag, and very limited lens options. But they are just the start, the first of a breed of camera that is sure to be the nail in the DSLR’s reflex mirror. Many photographers might hesitate to jump ship right away — the a7s aren’t ideal for sports photography and other specific disciplines — but once Sony builds out the lens options and improves the autofocus, it’ll be all but over.”
Sony is on a tear, and has been innovating up a storm. Fuji’s been doing great with their lenses, too. It feels like the next generation is going to finally start getting this stuff down.
