Sony factory tour in Thailand – G Master lenses

We were lucky enough to be invited to the Sony production facility in Thailand  where they assemble all the top of the range Sony equipment including the new G Master series lenses, what a treat we where in for!




Sony have developed the new E Mount G Master lenses to match the performance of the Alpha 7 cameras, delivering ultimate resolution and beautiful bokeh. The range has been launched with a 24-70mm f2.8, a 70-200mm f2.8 and an 85mm f1.4.


All three lenses gave a stunning performance on the A7R II and A7S II. ‘Bokeh’ refers to the aesthetic quality of the blur produced in the out-of-focus parts of an image produced by a lens. Bokeh has been defined as “the way the lens renders out-of-focus points of light”.  Sony’s precision lens polishing, combined with an eleven blade iris, produces a superbly smooth blur with no trace of banding or irregular shapes. We were shown a series of technical tests comparing the new range to each lens’ competitor. The results were stunning.  Only the Zeiss Batik 85mm f1.8 compared for sharpness.


G Master series lenses take imaging and expression to previously unattainable levels with a stunning blend of extremely high resolution and softly dissolving background. The three lenses are designed to be future proof easily good enough to get the best from an 8k camera. 


They all have the new XA element. An XA (extreme aspherical) element with superlative surface precision works with ED elements  for extraordinary resolution that can capture breathtaking texture and detail. Giving very smooth results, no more jagged edges and creating soft background blue. Superlative surface precision means an accuracy of 1/100 of a micron, 1/100,000 of a millimetre.  Equivalent to a small pebble on a football pitch.  Sony proudly believe that they are the first to achieve this level of precision in manufacture and so unique in offering lenses of this quality.



Sony Thailand are dedicated to producing quality products.  The care that is put into producing each lens and camera is amazing.  We were fortunate to be allowed to see the cameras being assembled with such precision, yes by human hands.



We only had time to look in on the lens production.  Although we were wearing factory issue slippers, it was insufficient to be allowed into the lens area.  There are two sealed entrances to the lens production lines to keep out dust and ensure that the lenses leave the assembly line in perfect condition.
