Sony Rolly (mini) review and video

I have to say, when Sony asked me to review the Sony Rolly I’d never heard of it, when they then explained it to me it sounded like a terrible idea. However, when it arrived a week ago and I’d had time to play with it I decided that it was actually quite cool.

The Sony Rolly

So what is the Sony Rolly? It’s actually quite difficult to define. Is it an MP3 player? Is it a toy? Is it a bluetooth speaker system? The answer to all of these questions is yes.

Looking a little like a rugby ball with wheels I expected the Rolly to be about that size, however, it actually fits comfortably in the palm of your hand.

The Rolly has 1 or 2GB of internal memory (depending on the model) which can hold your MP3 music. To transfer the music to the Rolly though you’ll have to use the supplied PC software called Rolly Choreographer. There’s no MAC version of this. The Automatic Choreography feature uses 12 tone analysis and beat analysis technology to analyse music on your Rolly, and then automatically creates motion that matches the music. You can manually work on the choreography if you want using the software too.

Sony Rolly on its Cradle

When you turn Rolly on its arms open to reveal the built in loudspeakers that are on each end. Now Rolly can be used as media player without any dance movements or you can press the play button again and Rolly enters dance mode.

The display-less Rolly will play MP3 files, as well as ATRAC, streamed via Bluetooth from your computer or mobile phone. It also contains sensors that know which way is up, so that volume can be adjusted by turning the player clockwise or anti-clockwise, tracks can be changed by rolling the player forwards or backwards or shaking it.

It’s probably easier to show you what the Rolly is all about rather than tell you so have a look at the video below:

So how do we define the Sony Rolly? I guess you’d have to call it an entertainment gadget. Everyone seems to like it but then goes on to ask what it’s for!

Rolly with its stand

Whether or not it’s worth the £175 price tag personally I would have to say no. Sony’s robot technology is spectacular and you’ll want to watch Rolly dance for a little while before it simple turns into and expensive set of bluetooth speakers. Granted the audio quality is good but for the price you could by a high capacity MP3 player and basic bluetooth speakers and still find change from the £175. I guess if you are a DJ or Club owner then the cost maybe more justifiable. Or maybe you just want to own one of R2-D2’s distant cousins?

Camcorder group test (Part 2) Panasonic SDR-S7 review

Panasonic SDR-S7 Review

Like everything else these days, personal video cameras or camcorders are getting smaller and more convenient to use. We’ve gone from wallet-busting shoulder mounted behemoths of the late 80’s using tape to compact handheld devices that fit in your pocket and which can be had for less than £200. The Panasonic SDR-S7 is a typical example of the new breed of camcorders that have made “home movies” so much more accessible for all of us by being low cost and convenient.

General

I’m going to break with convention and avoid describing all the controls in detail as, by their nature, video cameras have a significant number of buttons, controls, menus and doo-dahs to operate them. However, controls have sensibly been kept to a minimum and this is undoubtedly a good thing when I watch how many people struggle with a normal digicam. Suffice to say, ease of use has been designed into the device and I found it remarkably easy to get to grips with without having to refer to the manual. This is a good test of any device and the Panasonic passes with distinction. I’m sure my mum could operate it!

The main control is a rotary switch that selects two operating modes for either motion picture recording, motion picture playback, still picture recording or still picture playback. To the left and above this switch is a menu select, auto-mode select, manual mode/auto-manual focus select and a 5-way cursor keypad for menu selection. On the top of the body there’s zoom-in/out controls and to the front on the right hand side next to the lens there’s a switch that opens or closes the lens cover (there’s no separate lens cover to be lost here – good thinking).
To the rear of the camera body behind a flap there’s a power jack, AV-out jack and USB socket for direct connection to a pc. Next to this is a dual function switch that either activates the camera shutter or starts/stops video filming. Now I realise that might sound fairly complicated, but in reality it’s not and in everyday use there’s only the rotary on/off mode select switch, the shutter release and the zoom controls to bother yourself about.

REVIEW

The Panasonic is an extremely compact device – in the hand with the screen closed it’s little bigger than many current mobile phones.

It’s easy to use and pretty much foolproof. Fold the screen out, power it on by using the rotary mode switch, selecting either video or still camera mode and, depending whether or not you use it at eye-level or waist-level, start filming by pressing the record button on the rear of the camera or the right side. The whole process takes less than 5 seconds with a very impressive start-up time. This reduces the chances of missing film-worthy action and helps to ensure you can capture those entertaining moments. The only potential gotcha here is forgetting to open the manual lens cover. I am sure we’ve all done that before!

There’s a manual focus mode and manual exposure mode that gives more control over the shooting options available, but to be honest that sort of defeats the object of this kind of camera. Its forte is quick operation and convenience so, the best thing to do is leave it in auto, leave the lens cover open, point it at your subject and get on with filming. It’s worth pointing out at this stage that if you are after high-quality footage then you should look beyond this unit. Resolution is 704 x 576 and, depending upon the recording mode used (there’s three levels of compression) you can expect to get between 50 minutes and 3.25hrs of footage on a 4GB SDHC card.

For a budget model the Panasonic copes quite well in low light levels which, is just as well because there is no built-in light. There was some discernible noise, but by the time it’s been mangled by YouTube or other online services it wouldn’t be noticeable.

Shooting with the camera at eye-level is not as natural or convenient as it would be with a more traditional kind using an optical or conventional viewfinder. In fact, I found using it in this manner resulted in wrist strain. However, it excels at waist level filming, which is a good technique to use if you want to remain fairly discrete. I can imagine this camcorder is ideal for parties and it’s the sort of device that I’d like strapped to the side of my motorcycle for a bit of fun.

The 10x optical zoom is fairly modest by camcorder standards – I didn’t investigate the digital zoom as this inevitably destroys image quality and, as a photographer, I am very fussy about that. The limited zoom isn’t an issue though because it encourages the user to get in closer which, almost always results in far better and more personal footage.

As a camera things are not so rosy. The resolution is very low at 640 x 480 making images look grainy and dull so, I would only ever use it in an emergency. There is no built-in flash so, it would only be usable in good light and therefore it’s no better than a very basic phone camera. In fact, you are probably better off using a camera phone. This might sound a bit harsh, but to be fair to Panasonic it’s not intended to be a still camera.

Battery life seemed to be adequate with about 1 – 1.25 hrs use being possible depending upon how much zooming in-out I did and what compression mode was used. It might not seem much, but it’s about par for most DV video cameras and enough considering its intended use.

Conclusion:

There’s much to like in a package like this. It’s compact, easy to use, convenient and fairly robust. At a push it can also double as a camera. At around £190 plus the cost of a high capacity SDHC card, the price is now within reach of many of us without causing the credit card to freak out. If you’re serious about filming then like most consumer devices you really should look elsewhere, but if you’re looking for something to publish to YouTube, your blog or for capturing little clips for family entertainment then there’s not much wrong with the Panasonic. I can’t see many of us being too dissatisfied with it and I’d be happy with one of these for casual everyday use.

Join me again soon for the next camera in the Camcorder Group Test or head over and look at Part 1 to see which cameras we are including or take a look at my Toshiba Camileo H10 review or Sanyo Xacti HD700 review.
