Sony's G Master lenses are the best the company has to offer, but Sigma's Art series often offers comparable performance at more affordable prices. If you are looking for a top-notch portrait lens and wondering which is right for you, check out this helpful video comparison between the Sony FE 85mm f/1.4 GM and Sigma 85mm f/1.4 DG DN Art lenses.
Coming to you from Dustin Abbott, this great video comparison pits the Sony FE 85mm f/1.4 GM against the Sigma 85mm f/1.4 DG DN Art. Both the Sigma 85mm and Sony 85mm are top-end portrait lenses that pair a wide maximum aperture with pleasing bokeh and great sharpness, but with Sigma's offering coming at $600 cheaper than Sony's, you might be wondering if you can save some money without losing performance by going with the Sigma. Another thing to consider is that the Sigma's new design is noticeably more compact than its predecessor and saves you about 7 oz of weight over the Sony, which is worth considering if, for example, you are carrying a bag of lenses around all day (wedding photographers). Either way, it's hard to imagine you will be disappointed by either. Check out the video above for Abbott's full thoughts on the two.
I personally want to sell my GM to get the sigma for size alone and maybe sharpness but the amounts of pincushion distortion have me reconsider, also the slightly better bokeh of the GM for portraits makes it a difficult decision.
