GoPro 2 vs GoPro 3
In mid-October, the U.S. company GoPro has dealt a decisive
blow to competitors by launching just three models Action cameras -
compact digital camera designed specifically for outdoor enthusiasts and
extreme sports. I got to test a new line of average camera - GoPro HD
Hero 3 Silver Edition, positioned as a direct replacement of the second
generation of Go Pro HD. What is really different new camera, and is it
worth it to buy? Read my special test!
Evolution of GoPro camera
GoPro cameras have been quite a few evolutions for almost ten years.
In 2004, the first GoPro camera was filming a photo on 35-mm film, the
current model of writing quality digital video in Full HD. Introduced in
October 2011, model HD Hero 2 caused a lot of noise, enhance the image
of GoPro as a leading manufacturer of action-kams. Why?Compared with the previous model, HD Hero 2 has provided the ability to record high-definition video (HD) in the following formats: 1920 × 1080 (30fps), 1280 × 960 (48 or 30fps), 1280 × 720 (30 or 60 frames ) 848 × 480 (120 or 60 fps). Photo quality has increased due to the 11-megapixel, and the matrix. Ability to select the viewing angle and optimum shooting mode, and the power of the protective housing and a wide range of accessories instantly made %u200B%u200Bthe HD Hero 2 a hit not only for athletes but also for video operators who shoot a variety of subjects (from weddings to reports from the jaws of a crocodile ).
What changed?
A year later, GoPro has introduced a new series of HD-cameras third
generation. The lineup is now as much as three models, and testable me
Hero 3 Silver Edition is exactly in the middle. Retail price of this
model is similar to the one on which HD Hero 2 sold before the new
items, and the company itself GoPro does not hide the fact that Silver -
direct replacement for "kopeck piece." What has changed in the new
camera?The GoPro 3 camera body
The first change is obvious and evident - Hero 3 has received a new, more compact and lightweight body.
More slim
The width and height of the case have remained the same, but Hero 3 was almost twice thinner than its predecessor.
Faceted body
Faceted body of GoPro Hero 3 is much easier to hold, and the rubber grip around the perimeter much more pleasant to the touch than the smooth plastic on the Hero 2.
Push button size
By changing the size and material of the control buttons - now it's not rubber "pins", and full wide buttons.
Using them is much more convenient than before.WiFi module
Managed by the camera with two buttons - is also, like the previous model, but there was one side of a new button that is responsible for initializing the module Wi-Fi.
Connectors
Connectors are now closed removable cap, which is quite easy to lose.
Itself has changed set of connectors - now instead of three video
connectors (HDMI and two jacks for video and audio) was a Micro-HDMI.
Next to him, placed a standard connector mini-USB. To use an external
microphone will now have to buy an adapter that plugs into the
USB-connector.Back view
Located on the back of the connector accessories - battery or LCD-screen.
These accessories from Hero 2 fits seamlessly.Smaller battery
Camera battery was smaller. The battery cover is also proportionately reduced, and got a new retainer.
Capacity lithium-ion battery is 1050 mA / h, which is 50 mA / h less
than the Hero 2, but while the Hero 3 without the use of Wi-Fi module
stated the same - about two and a half hours.Micro SD
Another change - instead of the standard card SD, Hero 3 is used in baby-Micro SD.
The maximum capacity of 64 GB card, against 32 in the previous
version. Cards must be Class 4 and above, but if you want to shoot
continuously, you need to use the cards grade 10 and above.New optics
All models Hero third generation received a new 6-cell unit aspheric
optics. The new lens makes the picture more clear and gives less
distortion at the edges of the frame. Of course, distortsiey still
visible, because the camera angle is 170 degrees, but the picture looks
much more natural.The hardware of GoPro 3
Technically, the new model has the same characteristics as the Hero
2. The underlying platform A5s, developed by Ambarella, a world leader
in the production of video processing. ARM11 processor has a clock speed
of 528MHz, and on the fly compresses video standard H.264. 11-megapixel
sensor and is similar to HD2 - sensor size are the same 1/2.3
"svetochustvitelnost is .84 V / lux-sec.The key difference from Hero 3 Hero 2 is the presence of built-in Wi-Fi, allows to fully control the camera using a proprietary remote control ... or a tablet or a smartphone platform, iOS or Android. To connect the camera to your smartphone simply download and install the free application, and then turn on the camera, and Wi-Fi to connect your device to the grid appears.
Then simply launch the app, press the "connect" - and get full access to the camera, and the ability to view the preview image that the camera sees, almost live. Why do I say "almost"? The fact that the image is transmitted with a small but perceptible delays that must be considered. The delay between pressing the shutter button and firing the camera is about half a second.
The practical significance of this "chip" can hardly be overestimated - because now you have the opportunity to install the camera anywhere and control with what's in the frame, with the help of your smartphone or tablet for a perfect composition. Without a doubt, this innovation is able to attract new users to the GoPro - not just maniacs extreme and ordinary fans of advanced gadgets.
This is important: Before using a new camera Hero 3, make sure that you have the most recent version of the firmware. In the box with the camera, even there is a special card with the appropriate appeal - to immediately update the software. Probably, the fact that the camera sent into production before the advent of applications for iOS and Android, and this part of the firmware was later changed. With the old firmware Wi-Fi worked for me only on Android. Iphone and Ipad camera saw. But after the camera firmware through the site GoPro, in the settings menu Wi-Fi has item Phone & Tablet, required to interface with mobile devices and the camera began to work with all mobile devices as it should be.
Soft
Despite the general Hero 2 with hardware base , Hero 3 has a more
sophisticated software , which by default gives the customer more
options for recording video and photos.First, now on all major resolutions , you can shoot in the 24/25 fps. Second, the camera's menu has a new mode Protune, developed together with the guys from CineForm, a company which codec was used for post-production film Danny Boyle's " Slumdog Millionaire ."
If you activate Protune, you not only get the opportunity to manually select the white balance (Auto, Manual, 3000K, 5500K, 6500K, and Cam Raw), but above all , capture video of 35 megabytes per second, which brings the Go Pro Hero 3 to the professional cells.
More than two-fold decrease in compression (normal flow - up to 15 Mb / s ) is beneficial to the quality of the image - the output you get less contrast and less saturated picture, which, however, has less noise and more details in shadows and bright areas of the picture, which makes this mode is indispensable for shooting and then edit the video.
In fairness it should be noted that the regime Protune is contained in the firmware update for the camera Hero 2 , which can be downloaded from the official website of GoPro. Before this release , Protune tested only a few lucky ones - for example , an expert Bear Grylls Survival and operators channel Discovery.
It appeared Hero 3 is another new mode of operation - Video Looping, allowing to repeat the recorded parts as necessary.
Protective case
Camera Hero 3 has received a new protective case which has two major differences from the previous model (besides the obvious change the size).
New flat outer lens provides a big advantage for underwater
photography, which I have seen for myself during the testing of a
similar case for Hero 2.Flat lens does not interfere with focusing, and underwater Hero 3 will be able to make professional-quality images. However, in comparison with the prototype, building "three rubles" was reduced optical port, which favorably affected the appearance.
Housing as before, waterproof, and can be used at depths up to 60 meters.
The second important difference of the new building - changed the lock mechanism, now became a little smaller and more reliable. Open the housing now is not by chance (albeit at the last version I have never happened.)
In addition to these key points, the case got a third button - to operate the Wi-Fi.
Mounting is completely identical to the previous model, so all the fasteners fit without problems. The compact form factor of the new building to tilt it at high angles relative to attachment that extends the options for shooting.
