| p.2 #15 · Canon EF 200-400 f/4L IS 1.4x TC Video Review |
The 'problem' with this and many video reviews is they're loosely scripted or simply ad-libbed and end up repeating the same points multiple times, which he did. Seven minutes could have been condensed to a couple minutes instead. Anyone interested in this lens knows it's a 200-400 f/4 with 4-stop IS, built-in TC... just show us how the TC swings into place, which he did. I agree he totally omitted any comment about AF performance. Given the ad-libbed nature, it might have been accidental, but you never know. As for his price prediction, it seemed completely speculative. He might be right, but the way he presented it offers no authoritative confirmation.
What I found most valuable was seeing how the TC moved into place, i.e. the impression that there is some friction/resistance involved, which seems good; that it will take external TCs; his impressions about image quality. Really, it's the IQ I care most about, since I essentially want this lens to replace a 400 IS v.1 and will probably be shooting it 99% of the time at f/4, meaning it needs to be quite close to the quality of the 2.8 lens wide open, at 400mm.
