Sample #6 @ 200mm + Canon 1.4X Extender (280mm)

This page shows the performance at 200mm with the Canon 1.4X EF Extender II, using sample #6, the best of 6 samples that I tested and that I now own as my personal copy.

Adding the 1.4X Extender II drops the maximum aperture to f/4, and increases the focal length to 280mm, for a 98-280mm f/4 zoom. I did not test shorter focal lengths, as in my view the loss of speed and quality at f/4 are simply not a good idea; the combination makes sense in order to extend the long end eg the 150-200mm range.

Capture and processing

ISO 400 was used to keep minimum shutter speed of 1/400. Remote release and Live View used to ensure sharpness. Multiple aperture series were shot and checked.
