We first heard about Sony's pro-level FE 400mm F2.8 GM OSS lens back in the winter. This past weekend we finally had the chance to put this impressive sports/wildlife lens to the test at a professional soccer match – read our first impressions. We even had the chance to toss on the Sony 1.4x teleconverter for some shots at an 560mm equiv. field of view. Have a look for yourself at the results.
