Hitachi DZ-BD70E review: Hitachi DZ-BD70E

The format war is over and with Blu-ray victorious, the Hitachi DZ-BD70E attempts to claim the spoils as the first Blu-ray camcorder on the market. Recording 'Full HD' footage on to Blu-ray discs, this shooter also provides plenty of features, plus an interactive guide for use

With the format war now over and Blu-ray victorious, Hitachi should be on to a winner as the first to bring a Blu-ray camcorder to market. Available for around £569, the DZ-BD70E camcorder, which records video footage on to Blu-ray discs, is a high definition shooter that records 'Full HD', 1,920x1,080-pixel video.

The Good

Records to Blu-ray discs; viewfinder and accessory shoe.

The Bad

Chunky frame; slow to process footage.

The Bottom Line

If Blu-ray is the future of disc-based media, the Hitachi range of Blu-ray camcorders score cool points with anyone looking for the ease of disc-recording with the image quality of high definition. The DZ-BD70E has some image quality issues, but is stylish and capable, with a number of interesting features

The BD70E is decked out in silver and grey, with nifty flecks of blue. One of the downsides of disc-based camcorders is the bulk of the frame, because of the physical dimensions of the disc. It's chunkier than tiny hard drive-based camcorders, but it's nicely balanced and not too heavy. Controls are well spaced and the zoom rocker is pleasingly responsive.

Despite the camcorder's slightly bulbous size, the controls are evenly spaced

The fold-out 16:9 screen measures 69mm (2.7 inches), which is a perfectly respectable size but feels small next to the bulbous midsection. You can choose to use a retractable electronic viewfinder instead, but like many EVFs, motion blur can be hard on the eyes.

The essential HDMI and USB connections are included, although they take some finding. The box also contains a remote control and 8cm Blu-ray disc to get you started, which is handy as recordable BD-R and rewritable BD-RE discs aren't cheap. An unpowered accessory cold shoe is also available for attaching extra kit.

The disc compartment is powered, so when the camcorder is off you can't retrieve your disc: annoying if the battery dies.

The BD70E packs a creditable 5.3 megapixels on a CMOS sensor. This means that decent stills are possible, but sadly not while the camera is recording video. You also get a 10x zoom.

The interactive guide function is an excellent idea. It leads you through options clearing up the tricky question for new users of which cable is required to connect to their televisions. Cleverly, this includes illustrations, such as different socket types. Unfortunately, the only other options addressed are what kind of disc you need, and how to set the mode switch. Illustrated guides to all the shooting functions would have made this feature truly impressive.

A 7.5GB disk will hold 1 hour of Full HD footage, or two hours of lower resolution HD. The 7.5GB Maxell single-sided rewritable Blu-ray mini-disc provided costs between £35-40 if bought separately. Discs don't have the fastest reactions: even the shortest 5-second piece of footage took 20-30 seconds to write. A 'disc access' message remains onscreen and new footage could not be recorded, or functions accessed, in this time.

When the camera is switched on, the screen powers on in 6 seconds, with the disc access message onscreen for a further 6 seconds before the camcorder is ready to shoot. A quick start mode keeps the camera on standby for a limited time, with power-up and recording virtually instant.

A Blu-ray disc is included, but since the compartment is powered, you can't retrieve it if the battery dies

HD footage is crisp and sharp, with occasional compression artefacts. Motion blur is present when panning. The autofocus copes well with zooming and moving the camera, but only if moving fairly slowly: quick zooms see the focus drop out and the struggle to regain focus is hit and miss.

Autoexposure is surprisingly easily confused. Highlights tend to be blown out, especially when moving from dark areas to highly-contrasted light areas. For example, if moving from a street scene to the sky, detail is lost in the sky.

In indoor conditions, there is a lot of noise with the attendant loss of detail, but the autoexposure holds up better than expected when adjusting for light sources.

As the manufacturers of the only Blu-ray camcorder on the market, Hitachi holds a unique position. With the format war only just coming to an end, consumers haven't fully committed to Blu-ray yet. As such, it's unlikely many people are desperate to own a Blu-ray camcorder, cool as it is.

The DZ-BD70E certainly beats DVD-based camcorders' storage capacity, but we wonder if physical media is a blind alley in the age of giant hard drives like the 100GB Sony HDR-SR7. It's a decent and stylish, if slightly chunky, shooter. It's just not the best option for anyone wanting the convenience of disc recording with the quality of HD.
