Is there a site that posts how many units a certain camera has sold? Mostly out of curosity, I guess. I know JVC sold 12,000+ of the HD100u, but how what about all the others?
The Panasonic HVX200 had sold around 10k in the first 9 months. Estimates are it's around 20k now.
From what people have gathered from calling retailers, it seems that the XLH1 is currently the lowest selling of the cheap HD cameras because of it's considerably greater cost and 24f which still has some issues with NLEs. The HD100 was selling quite well untill the HVX200 came out. Since then the HVX200 seems to have taken a lot of it's business and is doing really well, especially on bigger features as a POV cam since the DVCProHD codec cuts better with film than HDV because of the HDV motion compression. The Sony Z1 was initially met with much excitment from the film industry but it's video-ish look and, more importantly, it's HDV motion compression quickly turned most off of it (some statments indicate that the bad HDV performance of the Sony is why some have been slow to embrace the XLH1 even though it has a much better HDV codec with more I frames). That said, the Sony Z1 and FX1 are almost certainly the best sellers of the bunch with the Z1 being a very popular choice for wedding videographers because of it's low light performance and the FX1 being very popular since it's such a cheap HD camera. The average guy who doesn't know a lot and hears the term "HD" is all to happy to grab and FX1.
Panasonic US said they sold 10,000 in the first 3 months, not the first 9 months. If you believe the numbers are accurate, and presume that sales strength has continued, that would put them at around 40,000 in the US. Keep in mind that in the first 3 months there were no European/Australian sales at all, as the unit wasn't launched overseas until the middle or end of April. So presuming that the rest of the world does at least as well as the US territory does, that could put the total number out there in excess of 60,000 or 70,000 units.
But that's extrapolation and speculation based on a) a press release from Panasonic US at NAB April 2006, and b) talking with dealers and gauging continuing sales strength. There is no way to know truly how many units are actually sold; only if the company chooses to reveal that number.
