Panasonic Lumix G3
Major HD video recording limitation on the Lumix G3: Cannot lock exposure during motion picture recording. I think Panasonic has omitted this rather basic motion picture recording option to force an upgrade purchase using one of their other DSLR cameras, or an entirely separate HD video camera, that DOES lock the exposure during HD video recording. You can lock the focus while recording video, but not the exposure. Even in manual mode you cannot lock the exposure during video recording. Ironically, the shutter speed can be locked using the "Flicker Red" menu item (i.e. 1/50th or 1/60th speed or faster). If you see any annoying flicker, even after locking the shutter speed, it's the camera adjusting the aperture and ISO settings during motion picture recording (and this is obviously NOT suitable for professional video recording). The still pictures from my Lumix G3 are undoubtedly fantastic and breathtaking--and you can do stills with Focus and Exposure locked--no problem (I almost always use this feature). But NOT with motion pictures. For boasting the G3's HD video recording side, I'm quite angry about this unusual, perhaps calculated, limitation!!!
