- get the correct memory card to run this camera for 4K - needs a cradle to turn into a handy-cam with display (SONY if you're listening) - it is harder to live with than the GoPro4 B (hard to explain why, but that's why you should get this, as its off the norm) - it is sleeker than the GoPro4 B,...

sleek design - stereo audio with noise reduction - image stabilization is smooth - great optics (1080p and 4K better quality than GoPro4 B - affordable price - flexible file formats (better than GoPro4 B - good battery life - great alternative if you HATE GoPro4 Black - love the play memories app...

- flimsy backdoor (its gonna break over time; opening and closing to access the charging port) - cheap and plastic construction - fish-eye 4K in 60Hz video (normal 1080p in 60Hz - high temperature sensitivity for an action cam (overheating fast when ambient temp increases) - device doesn't always...

Worth a look if you're new to the POV camera market, but if you've already got a GoPro, stick with it.

- Excellent video quality; - Small without the case; - Splash proof without case

- Colors are oversaturated; - Stills aren't very good

For those of us of a certain vintage, it's almost impossible to believe that Sony could be described as an underdog when it comes to video cameras. But in the world of professional action cameras, it's fallen to Sony to play David to GoPro's Goliath.

Splash-proof without a housing; easy operation; image stabilization; GPS

Waterproof housing not rated for depths as low as the competition; colors can appear oversaturated; fewer resolution/frame rate options than the competition

Sony added its new Action Cam camera with 4K video recording to its Action Cam wearable camera lineup at CES 2015. The Sony FDR-X1000V 4K Action Cam has a similar form-factor as the previous Action Cam models and will cost $499 and $599 with the Sony Live View Remote, a utterly useful accessory when...

It’s exciting to see new competition in the action cameras arena. It's especially exciting to see some useful new features such as the GPS and handy sensor data used by the TomTom Bandit and Garmin Virb Elite, as they introduce new possibilities. Then there are other innovations, such as EE's 4G streaming, that we’re not so sure about. But GoPro has been doing this, and only this, for a long time - and it shows. The Hero4 has abundant mounting options and a focus on image quality and versatility that means it’s still the one to beat. Its free editing software is just as powerful, helping you to get carefully ­crafted action vids up in double­quick time. Having said that, £410 is a lot to spend, so we’d recommend looking at its cheaper cousin the Hero4 Silver (£330) to see if your needs can be satisfied for less of an outlay. It can only record 4K video at 15fps rather than 30fps, but does have a built­-in live-view screen. And if you don’t need 4K videos, the smaller Hero4 Session could yet prove to be your best bet. After that we’d consider the Garmin Virb Elite. Its video quality and editing package with G­-Metrix overlays are just brilliant, but most attractive of all is the price - it's practically half the price of the Hero4 Black. It's the TomTom that comes in third - it's overall design is really well thought out, and while it's automatic video editing isn't perfect, the innovation is to be applauded. And then there's the Sony FDR-X1000V - it comes second on the video quality front, but the usability is just a little too compromised. Finally, while novel and unique, the 4GEE’s focus on standalone streaming feels like a slightly misguided concept to us.

I love the new case, the ability to control the menu without taking it out of the case is huge. The new video options (4k and higher frame rate) are nice too, but as far as video quality it may be better, I didn't do a side by side, but it is not significantly better than several versions back.

Awesome.It was delivered within 3 days.The product is very good.The video clarity is almost unbelievable. If you planning to buy,don't think much and buy this.it is a superb product

I saw two movies this past weekend. One was about a terrifying futuristic dystopia filled with endless betrayal and a complete lack of hope. The other one was Mad Max: Fury Road There's plenty to dissect in Disney's new film Tomorrowland - from the misguided romanticisation of the 1960s as a...

Sony's 4K Action Cam is a capable POV camcorder that shoots great videos, but its size and price put it behind GoPro's Hero4 Black.

4K (UHD) video recording; Good-looking; smooth videos; High 100-Mbps bitrate; SteadyShot stabilization

Larger than most action cams; 4K requires SDXC card; Some quality issues in bright light; Pricey compared to competition

At the end of the day, in the action cam market, the buck stops at GoPro. Whether a company is trying to compete with them or not, they are the standard that everyone is held to.
