When Sony announced the A7R in 2013, full frame mirrorless cameras were in their infancy. We knew the A7-series had great potential, but we couldn’t have predicted how quickly the system would evolve and the impact it would have on tempting photographers to ditch their DSLRs and switch systems.
No sooner were 36-million-pixels accepted as the norm for a high-resolution full-frame cameras, Sony had manufactured its second-generation high-resolution model. The A7R II that made its debut in 2015 presented a ground breaking 42.4MP sensor, built-in 5-axis image stabilisation and an improved body design.
Two years later Sony revisited its A7R-series again. The A7R III upheld the same pixel count as its predecessor, but introduced many of the powerful features that originated in the Alpha 9, making it one of the best all-rounders we’ve tested in terms of resolution, speed and high ISO image quality.
Not one for taking its foot off the pedal, Sony has taken feedback from existing A7R users onboard and made over 50 improvements to its new Alpha 7R IV. The question is; has Sony made the best high-resolution full-frame mirrorless camera on the market?
