G Lenses
Sony G Lenses are an exceptional breed. They inherit a
distinguished pedigree from the original Minolta
®
lens line,
with industry-leading Sony design and quality assurance
technology added to push their performance to the forefront
of twenty-first century photography. G Lenses impart a visual
elegance to every aspect of the images they produce:
extraordinary presence at in-focus areas, smoothly dissolving
to luscious out-of-focus rendering that can provide a beautiful
foundation for captivating photographic art. Their handling is
extraordinary too, with intimate operation and response that
seamlessly connect the process of taking photographs to the
photographer's imagination.
