I have 85mm 1.4G, Sigma 50 Art and rented 58G. This 105E has better boke than those Nikons and as almost sharp as the Sigma 50 Art at its largest aperture. BTW, Sigma has horrid boke and bad rendering, especially body of water or wavy back ground patterns but it's sharper lens.
Smooth and sometime funky swirly Boke, Sharp at 1.4, almost no CA, relatively small size, lens produce addictive photos; Best Modern Boke Lens
Must compromise the Longer FOV than 85G and 58G for better boke and subject separation; Made in China, lens gives a bit when mounted, relatively pricey; Front cap has grayish finish instead of black; Pouch seems thinner and cheaper than earlier pouches.
