Starting early in the mirrorless race, Sony managed to build the biggest lens arsenal, compared to all its competitors. Although they are quickly catching up, Sony users have the advantage of having more third party lenses to choose from. Some companies, like Tamron, don’t even have to reverse engineer Sony’s blueprints, as Sony Corporation maintains a 12.07% share-hold in Tamron (the second-largest shareholder). There is a reason why Tamron lenses are such a hit amongst Sony users. They work almost without issues, and probably the only place they still can’t match Sony’s native lenses is when autofocus in low light, and also that are not compatible with Sony’s teleconverters.

Year after year Sony proves that even the small diameter of the E-mount cannot stop them from producing very high quality and fast lenses. The GM series is no less than “perfection”. But even the “perfection” sometimes needs improvement, and Sony showed how they can do it with the second generation of their most popular (and arguably most used by professionals) zoom lenses – 24-70mm GM II and 70-200mm GM II. The last primes are also astonishing – like 35mm f/1.4GM or the 50mm f/1.4GM. But let’s see what Sony has as primes at the moment and then, as the title of the article suggests, to identify what is missing or needs improvement.
