As most of you are aware that Sony just launched 2 E-mount tele lenses, would you plan to invest on one? I am thinking that the 200-600mm is about 3.5k sgd and with a A6400, maybe near to $5k and not to forget a new monopod if you don't have one. I got 600mm from RX10 mk4 but the sensor a bit small but got 24fps, which A6400 is half at. Depends on budget, might be getting that combo, 900mm on birdies not bad
