Adapting on Early Sony Mirrorless CamerasĮarly mirrorless cameras used autofocus systems entirely different than dSLRs, requiring very different lenses. This post will address the issues with the Sony A-mount adapter. Despite being the first to the market, they actually have the worst adaptability of their old mount. Yet, ironically, Sony serves their former dSLR customers far worse than Canon and Nikon in terms of adaptability. For many, one joy of the Sony Alpha mirrorless system is the ability to adapt old lenses from other systems. Probably because they were a distant third in market share, they had the most incentive to shake things up with something new.
Sony was at the forefront of the transition from dSLR to mirrorless. Giving them fuller functionality is more challenging. At least to the extent of using them as basic manual focus lenses. Thus, every camera maker has come up with adapter solutions to make lenses compatible with a new generation of mirrorless cameras.īecause of the shorter flange distance of mirrorless cameras as opposed to dSLRs, it’s rather easy to adapt lenses. (In addition, third party lens makers added hundreds more).Ī major concern of switching to mirrorless has been preserving continuity for customers as opposed to telling them that every lens they have collected over the last 30 years is now worthless. Over 30 years, they built up libraries with dozens if not hundreds of lenses. When SLRs when digital in the 2000’s, these three camera companies continued with the same mounts.
Canon started an entirely new all-electronic mount for the autofocus era, the EF mount.
Sony/Minolta utilized the A-mount, Nikon had the F-mount which was continued from their pre-autofocus days. You had three major brands, each with a different lens mount. Minolta was actually the first to start autofocus SLRs in 1985 and their “A-mount” was taken over by Sony in 2006. Canon and Nikon both started making autofocus SLR cameras in the 1980’s.
All three of the big camera brands have now progressed in the move from dSLR to mirrorless.
