Round 2: Canon 100-400mm @ 200mm vs. Canon 200mm 2.8

Canon 450D at ISO 200, two lenses were tested again each others namely, both lenses are having date code beginning with UW:

1. Canon 100-400mm f4.5-5.6L USM
2. Canon 200mm f2.8L USM

Finally, let's see the prime at wide open (f/2.8), and you will know it's an exceptionally good lens!

No doubt that the 200mm f2.8L is always recommended for astrophotography.
