Sony Alpha Blog published a very lengthy in-depth review of the Sony FE 300mm F2.8 GM OSS which you can read in full here or check out the pro/cons below. SAB seems to be very impressed with the Sony 300mm f/2.8 even with a teleconverter, but the 1.4x TC can still achieve excellent/outstanding results while the 2.0x TC only reaches very good/excellent results with f/5.6 to f/8.0 being the sweet spot.
