捕鱼高手 - 试镜片
70-200mm f/2.8 IS at 200mm, plus Canon 2x teleconverter, plus Sigma 1.4x teleconverter -->> 560mm f/8 lens. (The EXIF shows 400mm f/5.6, but I assure you it is 560mm f/8).
The camera still auto focuses, but very slow. But this is a cheap way to get a long lens.

The photos were taken with hand holding the camera, without any support. Photos are uncropped, and you can see camera shake from frame to frame, which is expected at 560mm.
