Экшн камера сони обзор

Overall, though, the GoPro offers more versatility, more reliability, and just slightly better quality (Sony's fisheye drives me nuts).
It's an extended oval if you look at it head-on, and it's a rectangle if you look at it from the side. That photo was taken in a shadow as the sun was setting, but in bright daylight it's impossible to see. The lens distortion is really quite bad, leading to seasick-inducing images (especially with camera motion). That said, it does offer some nice features, especially if you opt for the Wi-Fi-enabled AS15, and video is on par with that of similarly priced models, though it's best suited for small-screen viewing.
Further, Sony's remote comes with a cushy (albeit chubby) wrist mount, whereas GoPro's is a small remote with no obvious way to attach it to yourself, and it needs an annoying proprietary charging cable. As you can see in the stabilization test at the end of the video, it reduces vertical bounce a bit, but side to side shake is almost worse, and ultimately it doesn't look much (if any) better than the GoPro, which I was holding in the same hand at the same time. We also evaluated for usability, accessories, and really pretty much everything else we could think of. GoPro includes a remote with the Hero 3+ Black, and Sony offers its LiveView remote either separately, or in a package (which brings the cost up to $370).
Mike and I both prefer the slightly warmer GoPro, which looks a little more natural, but ultimately, it boils down to personal preference, and you may gravitate toward vibrancy.
Because of its rounded bottom, though, it will almost always need to be in some sort of mount when being used, and although the included housing doesn't add a lot to its size and weight, it does add to it. On the back are a big record button and a hold switch so you don't accidentally start and stop recordings. Also, with the camera completely sealed, there's a good chance you might end up with some condensation inside that could fog the lens. The waterproof housing is only waterproof to 16 feet, which is ridiculous, and water really sticks to the lens. There are none of the squarer shooting modes (or a Super mode analog), so you're more likely to have your head or feet cut off.
Both cameras offer Pro modes which shoot at a higher bitrate, but they approach them very differently. It's the mode GoPro uses for pretty much all of their ads, so obviously the footage can look amazing in the right hands, but not everybody has those skills or that kind of time. Ideally, there should be a tripod mount on the actual camera, but really there's no room for one.
The action cam market is dominated by companies that don't have a history of making other types of cameras.
Sony has the option of a couple different color modes, but the default is Vivid, which is what we used for our testing. It has a full-color screen that allows you to view what you're shooting while you're shooting (and change basic settings) with very little latency. Even the simple head-strap is uncomfortable, awkward, and it's tough to get it at a good angle without filling half the frame with your eyebrow (full disclosure: I have big eyebrows).
But while the Sony produced sharper images on occasion, more often than not GoPro's images were just a bit crisper (look at the detail on my face and in the wrinkles on my shirt during the audio test above, starting at 2:27). Its first efforts in the category, the Sony Action Cam HDR-AS10 and HDR-AS15 (the AS15 has built-in Wi-Fi, the AS-10 does not), make a good initial impression, too.
Sony sells a pack of two other doors -- one with a flat lens for underwater use and one with mic openings -- for about $50. If I didn't have a means to transfer my footage right then and there, I would have been screwed. In addition to having built-in Wi-Fi, the AS100V also has GPS (something GoPro doesn't currently offer) and NFC for easier pairing with an Android phone. Ultimately, it may depend on how you're going to use the camera; if you value GPS more than waterproofing, the Sony should be your pick. The Sony Action Cam HDR-AS100V (real catchy name, guys) is Sony's latest answer to the GoPro. Thankfully most of Sony's mounts have a tripod screw hole (the camera itself has a mini-tripod screw hole, but you aren't likely to find anything that will work with it), which opens the door for more secure options.
For surf shots (or really anything where you're shooting back at yourself from a short distance), the GoPro can shoot in Super Mode, which basically shoots a taller image and then squishes it down into 1080p or 720p (your choice), somehow without making it look warped. More to the point, though, is that the GoPro is far more waterproof, has more (and better) mounting options, more (and better) shooting modes, and is simply easier to use in the field. That said, it's digital image stabilization, not optical, and it just doesn't work all that well.
Both cameras have smartphone apps which allow for live-viewing, playback, record, and mode-switching, but Sony's (above) doesn't have nearly as many options.
Compared to the Sony, the GoPro has a tendency to blow out the highlights, but it also tends to retain better detail in the shadows. Sony is aware that this is a problem and they said they're working on it, but not timeline was given for a fix. The Sony really saturates colors a lot and skews pretty cool, which makes the blues in the sky pop.
The next time I went, I had it tethered to my board, and that little string saved it seven or eight times during the course of that session.
Pro Mode only works with a SDXC micro SD card, and despite the much larger file sizes there doesn't seem to be any noticeable gains in quality, but if you don't use Pro Mode you can't shoot in the more cinematic-looking 24 frames per second. It can shoot video at up to 1080p at 60 frames per second (or 720p at 120fps), and at a bitrate of up to 50Mbps.
I don't know if it's the rounded shape of the lens covering or the quality of the plastic, but the lens covering on the GoPro sheds water far, far more easily. There's also a cradle with a 2.7-inch LCD screen that flips out so you can use the Action Cam like a traditional handheld camera, albeit a very small one.
Battery life is fan-freakin-tastic, coming in at two hours and forty minutes of consecutive shooting (in 1080p 30fps with Wi-Fi and GPS turned off), compared to the GoPro's two hours and nine minutes. This enables you to put an overlay on your footage that includes fun stuff like trail info, miles per hour, and distance, though you have to use Sony's PlayMemories software to do it. The standard kit the Action Cam AS100V comes in is only $270—a full hundred and thirty bucks cheaper than the Hero 3+ Black kit. If you scratch the lens covering on one of the doors, you're stuck buying another two-pack or an entire $40 housing. GoPro definitely got better with the upgraded mic in the Hero 3+, but it's still nowhere near Sony's audio quality.
But here's the thing; we couldn't detect any perceptible difference between having Pro Mode on and off for the Sony. The two included mounts are somewhat large and the adhesive is somewhat weak, so you might be better off finding alternatives that use the tripod mount or just getting better adhesive pads.
It can shoot in wide, extra-wide, as well as squarer dimensions, and at a ton of different frame rates. Built-in GPS, is terrific and Wi-Fi generally works quickly and with less lag than the GoPro. Whatever the reason, in design and usability the Action Cam falls shy of models both above and below its price level.
Even if you can get a top-down view, the light is so dim that you can't tell if it's on or not in daylight (even on an overcast day!), and Sony's record sound is too quiet to be heard through the waterproof case in most environments.
We loved that feature on the Garmin VIRB Elite when we tested it in our Battlemodo, and we love it here, too. Both cameras offer options for Wi-Fi-based remote controls (and both work with smartphone apps).

The Bottom Line The Sony Action Cam is a solid first effort and worth its price, but some design shortcomings may be enough to put off some potential buyers. The menus are a bit easier to navigate, and the LiveView remote is really convenient at close range. The modes it has are probably enough for most consumers, but if you really want to tailor your shots to the thing you're shooting, GoPro offers more flexibility. We shot under an array of outdoor conditions, evaluated audio quality and low-light capabilities.
Both cameras claim a 170-degree viewing angle (at their widest setting), but Sony's seems a bit narrower (my face always looks a bit bigger on the Sony), and the GoPro's aspherical lens doesn't suffer from the fish-eye effect nearly as badly. In the first few moments that I surfed with it I duck-dived through a small wave, the camera popped out. So, when a manufacturer like Sony gets into the market, it's reasonable to think it might be able to make a great POV camcorder, at least in terms of video quality. The whole back, though, is a sliding door that covers the battery compartment and a card slot supporting both microSD and Memory Stick Micro cards. For professionals, either camera will work, though we recommend switching the Sony out of Vivid and into a Flat color mode if you're going to be grading it.
Not only could I not record, but I had to fully reformat the card before it would work again.
It eats up a lot of space on your card, though, and tears through the battery, so we don't think it's worth it.
Sometimes the camera wasn't rolling when it should have been, and sometimes I stopping shooting when I thought I was starting. The GoPro doesn't offer any built-in stabilization, but it does have the capability to shoot at higher resolutions, such as 2.7K at 30fps. On the side is a small LCD screen and two buttons that allow for navigating up and down through various menus and settings. On the bottom are two panels that cover ports to the micro USB port and to the micro HDMI port and microphone in. Sony's menu system is just a bit more intuitively laid out than GoPro's, and it's way easier to navigate because Sony has two navigation buttons (up and down) to the GoPro's one.
At times it can peak a bit, and sometimes it lets in a little too much ambient noise, but it's still the hands down winner for sound.
If you want to shoot in 24fps (my personal favorite, for a more cinematic look), you can only do that in Pro Mode (again, requiring a higher-end micro SD card). To Sony's credit, it offers a very wide array of other mounting options, but to be honest, most of them don't feel as sturdy as GoPro's, and it still lags behind in variety. We hate that it's not really wearable, but it beeps loudly and flashes when you're rolling. Because it's an exact mirror of the GoPro's screen, it gives you a very clear indication of what mode you're in and how much footage you've shot. But what's worse is that water droplets stick to Sony's housing like glue (see the surf shots at the beginning of the video above). You want to push that button once and know you're recording, and the Sony simply doesn't provide that.
Its newest entry into the increasingly crowded field looks like it might be one of the first legitimate GoPro alternatives.
As you might expect, it's a lightweight, rough-and-tumble, wearable camera for recording your various adventures. That means there's less camera to strap to the side of your head or wherever else you plan to mount it. It's been a while since I studied geometry, but I'm pretty sure there isn't a word for the AS100V's shape.
However, since the housing is waterproof, the stereo mics on the front of the camera aren't exposed, so when it's sealed you'll get nothing but muffled audio. Maybe Sony was trying to stay below a certain price or wanted the camera to be as small and light as possible. Sony is much louder and much more clear, giving you a far greater sense of the surrounding environment, making the resulting footage more immersive.
It's supposed to allow you to control up to five cameras at once and Sony sent us three so we could test it, but we were never able to get it to pair with more than one at a time. GoPro's app allows you really dive in deep and easily tweak advanced settings (color, exposure, etc.) and ultimately it's just a faster, smoother app to use. And because the recording indicator light is on top of the camera, if you're looking at the Sony straight on (which you will be if you're surfing, or doing anything where it's pointed back at you), it is impossible to tell whether it's rolling.
In contrast, the GoPro can shoot in Protune with a more standard micro SD card (tested using Sandisk and Lexar cards, both Class 10). Basically, it's a mode for professional users who are willing and able to take the time and do some advanced grading of the footage.
Sony sells desiccant packs, but you can squeeze a small silica gel pack (like the kind you'd find in a shoebox) into the housing and accomplish the same thing.
Many of the basic mounts lack the ability to change the tilt angle, which limits how you can use it. We strapped both cameras to the nose of our surfboard, we looked at how the cameras handle motion (both when the camera itself is in motion, and when it's recording moving objects).
Also its narrow and medium FOV modes all but eliminate image distortion (fisheye) completely, which again, is a major problem on the Sony.
Pry open the door on the bottom and you'll find Micro-USB and Micro-HDMI ports, an expansion connector for use with the aforementioned camcorder cradle, and an external mic jack, which is a rarity on action cameras.
Pressed metal tripod mount and latch on the bottom of the Sony Action Cam waterproof housing.
Sony's Pro Mode brings the bitrate up to 50Mbps and it retains the image correction that the camera does in its basic mode (so you can still shoot with colors in Vivid mode, and you don't have to manually sharpen the footage later). Pull another switch, and the back door opens up, exposing the battery and micro SD card ports. In previous versions, Sony achieved that by cropping the image, which greatly reduced quality. It's great that it's so sealed up out of the box, and the housing has a standard quarter-inch tripod mount in the bottom, so it can be used with a wide variety of available mounts.
The Sony's image quality is generally excellent, and more or less comparable to the GoPro Hero 3+ Black. Also, Sony's Pro Mode is only available if you're using a SDXC-level micro SD card, which are way more expensive and less readily available. Image quality is more or less comparable (each has its strengths), and while audio quality isn't as good on the GoPro, it's still really quite good. For this review we did some exhaustive comparison against the GoPro Hero 3+ Black, the winner of our recent Action Cam Battlemodo, and the all-around leader in this category.
This means you can use stabilization software (included in both Apple's FinalCut and Adobe Premiere), which will make it look extremely smooth, and you can still get a lossless 1080p shot. Here's the thing, though: you can't use the external mic jack with the supplied housing or any of the other housings or mounts available from Sony.
There's also what looks like a hole for a tripod screw, but in fact it's a smaller screw-hole so you can mount an accessory that allows you to mount a tripod. Easy-to-use menu system can only be accessed with the camera outside of the waterproof housing.
