It's all about the person taking the pics. The canon 500D ("T1i" here in the states is an awesom camera) It takes amazing video. I just upgraded from the canon xsi.
Great photos, thanks for posting them. Just FYI, this species is no longer considered Trioceros wiedersheimi but is now classified as its own species, Trioceros perreti. Here is an article on the change: http://zfmk.de/BZB/Band_57_2/231-240_17_barej.pdf
