These cameras are ENG cameras which typically means they have removable lenses and are shoulder mount cameras.\\ \\ 2/3" Camera examples: *Panasonic AG-HPX500 *Sony PDW-700 \\ ==== 1/2" cameras ==== The 1/2" cameras are the step between the smaller prosumer 1/3" cameras and broadcast 2/3" cameras. These cameras typically have 3 CCD or 3 CMOS sensors. Some 1/2" cameras also feature removable lenses.\\ \\ 1/2" Cameras examples: *Sony PDW-F350 *Sony PMW-EX1 *Sony PMW-EX3 \\ ==== 1/3" cameras ==== Many prosumer cameras fall into this category. These cameras typically have 3 CCD or 3 CMOS sensors, some have removable lenses and some do not. There are several different formats used with 1/3" sensors, from small hand held cameras, to larger ENG style cameras.\\ \\ 1/3" Handheld Camears examples: *Canon XH-A1 *Panasonic AG-HVX200 *Sony HDR-FX1 \\ 1/3" ENG Style Cameras examples: *JVC GY-HD100 *Panasonic AG-HPX300 \\ ==== 1/4" and smaller cameras ==== Most consumer grade cameras fall into this format. These cameras are generally very small, hand held cameras. These camera usually have anywhere from 1 CMOS sensor to 3 CCD, and normally do not have removable lenses.\\ \\ 1/4" and smaller Cameras examples: *Canon HV20 *Panasonic HDC-S100 *Sony HDR-SR11 ==== DSLR and HDSLR Cameras ==== TODO \\ [[http://prolost.com/blog/2009/12/3/you-didnt-believe-me.html]]\\ [[http://www.dvxuser.com/articles/article.php/20]]\\
