I realized I did not

provide specific information. Sorry. "Semi pro" (also called prosumer) or pro camcorders...

Prosumer: Sony HDR-FX7; HDR-FX1000

"Pro": Sony HVR-Z5, Canon XHA1, Panasonic AG-HVX200, Canon XF300 series.

The visible differences between the prosumer and pro models is use of XLR audio inputs vs 1/8" (3.5mm) stereo audio input.

All can record to high quality, low compression formats. The Sonys do DV/HDV (miniDV tape or external flash memory recorder module), the Panny does DVCPro/HD to P2 flash memory cards, the Canon does MXF to SDHC...
