The Sony 2.0x Teleconverter is designed primarily for the 70-200G lens. It is lightweight and compact. Reports from users say that the teleconverter doesn’t cause any degradation in picture quality. This should be a great addition to any photographer’s kit. Most professionals should have no reservation recommending it to fellow photographers.
Naturally, as the teleconverter makes the whole assembly longer, it is important for users to stabilize the camera. They can use fast shutter speed or tripod to avoid unnecessary blurring. Some teleconverters force users to drop the f stops by two, but it is not necessary with Sony 2.0x.
