We make short video productions and needed a compact portable easy to use 1080p camcorder. The HF M400 delivered what we needed, true 1080p 16:9 aspect video having very impressive quality. The HF M400 is packed with features, yet has a short learning curve and easy to use controls. We were able to make quality full featured video clips after only a few hours practice. The internal microphone gave good quality audio in face-to-face interviews. When mounted on a tripod the 10x optical zoom gave smooth pan and zoom effects. For hand held shots, optical image stabilization gave great results. If you like to get technical, the HF M400 is packed with features described in a 200+ page manual. We are very impressed with this camcorder after two months heavy use. If you need true 1080p 16:9 AVCHD high definition video capability, the HF M400 delivers. No tape, no hard disc is a plus. All video goes onto two SD cards. Easy to switch out. Many more useful features on this cam. Excellent quality for price.
