85mm size comparison between the new Sigma, Sony GM and my favorite Sony f/1.8
by way of CameraSize

Right here is the dimensions comparability between the three 85mm FE lenses. In that case I’ve little question the smaller Sony f/1.Eight FE lens is your best option except you really want that tiny quicker aperture. The GM is the bokeh king whereas the Sigma is the sharper than the GM. However I believe the Sigma is actually method too huge for my style 🙂
I do personal the 85mm f/1.Eight and it’s tremendous for my climbing journeys (gentle and sharp). Get it!
