The Sony FE 70-300mm lens got tested by the German guys from Photozone. They are not impressed by this lens performance:
Honestly, the Sony FE 70-300mm f/4.5-5.6 G OSS disappointed us a little. You are buying such lenses primarily for its potential at the very long end of the range which is where the performance may not be bad but it certainly doesn’t reflect the promises of a G-class lens nor its high price tag. Now that being said – the center quality is still very good at 300mm and that’s where most of the action is at this setting.
The lens is a bit expensive relative to its performance. If you want to have 300mm, you just don’t have another choice at the moment but if you can live with a little less we’d rather recommend the Sony FE 70-200mm f/4 G OSS instead.
Note: You now have a choice! The 100-400mm GM….but it costs twice as much 🙁
