The Sony 135mm F1.8 GM is a new jewel in the GM serie, it will produce excellent results in Outdoor portraits, sports, weddings, street photography. Compared to its biggest competitor Sigma 135mm F1.8 , the Sony is lighter, smaller , a little bit more sharper , has a better color rendition and its AF is much more faster and accurate, Background blur is a little bit smoother , Bokeh Balls are better, the only areas where the Sigma has the edge is a little bit better resistance to flare, and the price (1400 euros)
A must have is you like the 135mm focal length

Mirror, mirror on the wall, who is the sharpest of them all? It is the Sony FE 1.8/135 GM, at least for all lenses that I have used yet. It is the first lens where nothing happens when I stop down except of decreasing vignetting and increasing diffraction. Even the macro and microcontrast is completely there wide open.
Besides sharpness, I can also praise the good CA correction, low distortion, low vignetting and the close up sharpness.The proven GM build quality makes using this lens a joy, especially the large amount of manual lens controls is very useful.
