GoPro Hero Session review: Price
You’d be forgiven for being slightly confused about the Hero Session. It was originally launched a year ago, called the Hero4 Session, at £329. Today, it’s called simply the Hero Session and costs £149.99. Yet it’s the same camera: GoPro slashed the price after poor sales. It’s also had a fair few firmware updates which addressed much of the criticism at launch. We’ll get to that shortly. One of the Session’s rivals is the SJCAM M20. It’s only waterproof when in its plastic housing, but it costs roughly half as much as the Session.
GoPro Hero Session review: Design and features
Quite obviously, the Session does not follow previous GoPro designs. It’s a cube and roughly half the size (volume) of the Hero4. Plus, it’s about 35 percent lighter at 74g. Better still, it’s waterproof without a separate housing.
This reduces bulk and weight, but also means better audio quality as the microphones aren’t sealed inside a plastic box. Notice we said microphones: there are two – one front and one rear. The Session automatically switches between the two to try and get the best quality and cut down on wind noise. It’s not entirely successful – wind noise is still an issue – but compared to previous generations of the Hero (particularly the second gen) and many rival action cams, audio is very good indeed. There’s one missing feature: a preview screen. That means you have to either guess if your framing is right or use the free GoPro app on your phone. The app is also used to adjust settings and can also work as a remote control to start and stop filming (or take photos). If you don’t fancy using a phone, GoPro also sells a ‘smart remote’ – you can buy it from Currys for £58. This doesn’t give you a video preview, though. Live previews aren’t available in all video modes, such as when you enable ProTune (below, left). You can change the field of view in some modes, but in some, there’s only Wide. The SuperView modes are distinct, so you have to select them when you choose resolution.
The Session does have a tiny LCD screen so you can check the mode and tweak a few settings, but with only two buttons, it’s more fiddly than breaking out your phone and launching the app. It’s useful for a glance at battery life.
GoPro Hero Session review: Shooting modes and resolutions
It won’t shoot in 4K like its big brother the Hero4 Black, but it will do 2K (sort of). Here’s the full list:
1440p at 30fps1080p at 60 or 30fps (48 or 30fps in SuperView)960p at 60 or 30fps720p at 100, 60 or 30fps (60 or 30fps in SuperView)
So, there are a couple of points to note. First, 1440p is not the 2560×1440 you’d expect. Instead, it’s 1920×1440, which is a 4:3 aspect ratio. The 720p100 mode is the most useful for slo-mo but it’s a far cry from the 1080p120 or 720p240 modes which a lot of modern phones support. Essentially, there are better choices if slo-mo is a priority. For photos, the Session can take single 8Mp stills, a burst of stills, intervals (for time-lapse) and it also supports loop recording so you could – in theory – use it as a dash cam.
GoPro Hero Session review: Ports and accessories
In the box you get a meagre selection of accessories, including the open frame plus curved and flat adhesive mounts. The USB cable is useful as it’s used to charge the Session. The battery isn’t removable – shock, horror – which will be a deal-breaker for some. It means you can’t simply pop in a fully charged spare when it runs out; it takes roughly an hour to fully charge from empty. The microUSB port and microSD slot are behind a sprung door so the camera isn’t waterproof while charging. You can use microSD cards up to 64GB, and GoPro says you need a Class 10 or UHS-1 card. Here are the best microSD cards to buy. We mentioned drones at the start, but really the Session isn’t a drone camera. It doesn’t have a video output and you can’t realistically use the Wi-Fi connection and the app for FPV. As the Session is square, you can put it into the frame in any orientation you like. This gives you more mounting options, and the camera will automatically rotate video when it’s upside down.
GoPro Hero Session review: Firmware
The latest firmware update (v02.00) added quite a few handy features, including extra ProTune options including the ability to select Flat colours as well as GoPro Colours. One frustration when the Session originally launched was that you couldn’t take a single photo without using the app. Now you can switch between single and burst photo modes on the camera itself. The update also improves the time it takes to connect to the camera over Wi-Fi and the camera now turns on quicker when you press the info button. It still takes a few seconds to turn on and start recording when you press the record button, but you quickly get used to this delay and instinctively hit the button if you suspect there will be some action worth capturing about to happen.
GoPro Hero Session: Performance
Understandably, video and image quality isn’t up to the level of the Hero4 Silver or Black. But it’s still good. Footage is recorded at a maximum of 25Mbit/s and details are a bit softer than on the Black. But colours are rich and generally accurate, and the Session deals pretty well with changes in lighting without abruptly changing the exposure. Useful on some occasions is the Spot Meter option which forces the camera to expose based on a spot in the centre of the frame. You can easily apply exposure compensation, too, but it can be tricky to judge over- and under-exposure using the live preview on a phone. It would be nice to have a ‘zebra stripes’ option to make it obvious when the highlights are being clipped. We used the spot meter for this photo of St Pancras:
And this is a 100 percent crop of the centre so you can see the level of detail captured:
Another important point to note is the lack of any stabilisation. With the SuperView or ultra-wide angles you don’t notice too much shake, but when cameras such as SJCAM’s M20 include video stabilisation, it’s a shame the Session doesn’t have any. We might have to wait for the Hero5 for that. Here’s a handheld (on a selfie stick) clip shot in the standard ‘Wide’ 1080p30 mode, which clearly shows that there’s no stabilisation whatsoever: Battery life – a crucial factor for the Session – is good, under the right conditions. With Wi-Fi disabled and when shooting in 1080p30 in warm conditions, you should be able to record for around two hours. In cold conditions, you’ll be lucky if it records at all: some users have complained that the Session won’t work for more than a few minutes. Others, though, say it lasts around half the time as it does when it’s warm. GoPro is cagey about the actual operating temperatures of the Session.
