C920 vs C925 v C930
Reviewed in the United States on August 14, 2017
Have tested all 3 models recently for a low cost office vc setup. I would recommend the C930 for group video calls as the 90 degrees makes a huge difference. Between C930 and C925 the picture frankly is very similar and the key is the angle coverage. On the C920 - it's a price game - $20 lower for lower video quality.
C920 : Lowest price, good video and sound quality, angle 78 degrees
C925: Mid price -clear video and sound quality, angle 78 degrees - sharper than C920 and C930
C930: Highest price sharper than C920 but not as sharp as C925. Much wider at 90degrees -- much wider at 90 degrees - for my use this was the best for VC's where we have 4 people around the table - the wider angle makes a clear difference
