Photo gallery: JVC Everio GZ-HD40The Everio GZ-HD40 is a significant camcorder for JVC. The AU$1,999 model supports AVCHD in addition to JVC's traditional MPEG-2 TS format, offering more flexibility in your video-editing options. It also marks a shift from using three, low-resolution CCD sensors to a single, comparatively high-resolution CMOS sensor — a 2.7-megapixel 8.5mm sensor, if you're curious. The result is an Everio with video quality able to compete with similarly priced HD models from Canon and Sony.
Design and features
Considering there's a 120GB hard drive inside, JVC kept the HD40 reasonably compact at 73mm wide by 68mm high by 123mm deep, and with battery it weighs 123 grams. An otherwise identical 80GB version, the GZ-HD30, is available for AU$1,649. Out in front there's a 10x optical zoom lens but, alas, there's no optical image stabilisation, only electronic stabilisation.
Behind the lens on top of the camcorder's body is a serviceable stereo mic followed behind it by an accessory shoe for use with an external microphone attachment. It's worth noting that the shoe's cover is not attached to the body, pretty much guaranteeing that it'll eventually get lost. Another niggling design issue: like most straps on camcorders this size, it's positioned too low on the body, causing the weight to be off-balance and the camcorder to flop to the left with the slightest relaxation of your grip. In the case of the HD40, it appears the location is low to avoid having the strap block inputs, but that doesn't make it any less irritating.
Flipping open the 2.8-inch LCD reveals a set of buttons on the camcorder body's right side: Direct DVD for burning discs without a PC using an Everio Share Station, Focus Assist (explained further on), Play/Rec for switching to playback mode and back again, and Delete. There's also a Power button, although the camcorder does have an instant-on setting for when the LCD is opened. On the left side of the LCD are the remaining controls for menu navigation and settings: Menu and Index buttons and a five-way thumb-stick.
Ports include HDMI, AV and component outputs at the back above the DC input for power and charging, a mic input and headphone out on the body's right side near the lens, and a USB mini-connector in front below an LED lamp to lens' right. On the left of the lens is a switch for sliding the manual cover open and close. On the HD40's bottom is a microSD/SDHC card slot for recording still photos or AVCHD video to cards up to 8GB in capacity; MPEG-2 TS video can only be recorded to the hard drive. There's also a docking port for use with the included base that adds a FireWire port for file transfers.
The Everio HD40 has a number of manual controls for white balance, exposure, sharpness, shutter priority, aperture priority and brightness. You get manual focus, too, controlled by the stick to the left of the LCD. To help you actually see what's in focus JVC has a very handy Focus Assist feature. Turn it on and the LCD's picture becomes black and white, while what's in focus will be outlined in your choice of one of three colours. There's an exposure assistant, too, that puts zebra stripes across areas that are overexposed in your shot.
Changing settings can be tortuous depending on what you're looking to adjust. The Menu button gets you into a majority of your options, but important settings are buried three levels deep, and there doesn't appear to be any order. For example, switching between MPEG-2 and AVCHD — one of the major reasons for buying this model — requires you to press the Menu button, go to Basic Settings, find the selection titled Stream Format and then choose either SD Video, which is in fact MPEG-2, or AVCHD. Then once you're back out, you have to hit Menu again, find Video Quality and select what recording quality you want to use. True, this probably isn't a setting you'll be changing all that often, but it's illustrative of the rest of the menu system, so if you're easily intimidated by digging through settings, you may want to try the JVC before buying.
Recording speed options for AVCHD (MTS files) include XP at 17Mbps, a 12Mbps SP mode, or EP video at 5Mbps. JVC's MPEG-2 TS — recorded as TOD files — are 26.6Mbps variable bitrate (VBR) when set to full high definition (FHD) or 27Mbps in 1440 CBR (constant bitrate). The 120GB hard drive will store up to 10 hours of FHD MPEG-2 video or 15 hours of the more compressed AVCHD format at XP quality.
Performance
Video quality on the whole is very good. Colours lean more toward saturated than natural, but are definitely pleasing and enhance the high-resolution video. This was particularly true when recording in MPEG-2 TS, which produced a more consistent tonal range compared to the more digital-artefact blockiness of our AVCHD recordings. White balance, when left in Auto, was a bit warm and dull; it's definitely best to use the manual white balance option or one of the three presets (Fine, Cloud or Halogen).
Low-light performance was better than expected and actually quite good. There was some noticeable off-colour noise, but the amount was certainly acceptable for dim shooting conditions. As with most consumer camcorders' auto-focus systems, the HD40 tended to hunt in low-light shooting, causing it to bounce in and out of focus. Not surprisingly, the higher-bitrate MPEG-2 TS presented finer detail and smoother-looking video than the AVCHD results. But frankly as long as you're shooting in good lighting and unless you're really examining the video you'd be hard pressed to see a significant difference.
Photo quality is OK for a camcorder. It won't replace a dedicated point-and-shoot camera, but it's there if you need it.
Conclusion
For a high-def camcorder priced less than US$1,000, the JVC Everio GZ-HD40 has a lot to offer — especially if you're into manual settings and are not easily intimidated by digging through a convoluted menu system. However, the lack of optical image stabilisation is regrettable for a camcorder of this calibre.
