Brian Murphy gives a great first look at the Sony FE 400mm f/2.8 GM OSS and he spots just about everything the lens has to offer physically. It’s kind of interesting that Sony still has the lens labeled as underdevelopment since it was at the Pyeongchang Winter Olympics and B&H Photo has had a listing for quite some time. I wonder what kind of volume this lens will be produced in when it is read because if it’s very limited Sony could delay finalizing the design right up until launch. I know these lenses tend to be very limited demand, but I’m sure Sony will want to mass produce them for the Toyko Olympics so they can have a showing and possibly become the camera of choice for that event.
