The fast and the furious stills
Although a long time ago, someone tried to use mobile phones to film, but most of the regular production of films and television shows still to use professional, high-end cameras. Film industry and mysterious stranger to general audiences, those big expensive photographic equipment including DSLR enthusiasts are not necessarily called that name. Film cameras in use is what kind? Produced by who? Compared with normal cameras, mobile phones are there any advantages? Amid the fast and the furious 7 hot begin, will introduce the film mainly used camera and lens types, and see how large is created out of the equipment. Kenzo iPhone cover

About GoPro lots of people will definitely not be unfamiliar, the sports camera brand is now widely known, its products are not only widely used in film and photography, also bought by many photographers shooting personal video. GoPro products designed for optimization of high-speed motion scene, small size, light weight, suitable for fixed outside the car, helmet, drone shot down heavy large camera to take pictures.

The speed stress using the GoPro is the model of the 7 series new Hero 3/4. Machines weighing just more than 100 g, using a 1/2.3-inch 12 million pixel sensor, shoot or 1080p/120fps 4k/30fps high definition slow-motion video. Because many camera angle of the speed stress 7 crafty, GoPro usage is more also. However, due to the small size, this camera filming quality is not much stronger than the high-end phone, so it is not suitable for conventional scenes of the recording.
Alexa XT
The 7 speed stress using the main camera is Germany Barclays company Alexa XT camera. Haller is the world's largest photographic equipment business, its Alexa (Chinese name: Eliza) series cameras since its launch in 2010 to become the most popular digital cameras, widely used in films, TV series, MV, advertising and documentary photography.
Alexa XT is the Alexa series of new models, use a 24x13mm,2.8k sensor (resolution 2880x1620). For the index from the resolution, this sensor is still not as good as many television cameras, advanced SLR flagship mobile phone-cinematographer on resolution's request isn't as fanatical as ordinary consumers. Alexa XT photographers most satisfactory indicator of tolerance is as high as 14. The degree of tolerance is the screen contrast of light and shade, cell phone tolerance usually only 3-5 file, open the HDR is only about 7; Canon 5D3 DSLR RAW format photos with 12 less than the tolerance, it can not compare Alexa XT. Movie scenes often have strong light contrast, lack of tolerance of the camera in high gloss white is a significant loss of shadow detail, so has the film grade tolerance index Alexa became a photographer's favorite.
Also, Alexa's color is also very close to the film, post process is relatively simple. With rugged fuselage, very suitable for the complex environment of the Studio filming. A Alexa XT camera weight 7kg, video taken in raw format storage rate of up to 7Gbps, recorded on a dedicated high-speed SSD. Taken compared to cell phones common 24Mbps H.264 format, Alexa 900MB much data per second, the data does not do any compression, restore the objective is to maximize real-world scenarios. Such a machine is not cheap, Alexa XT covers the price of more than $ 60,000, so most users will be leased to save money.
RED Epic KENZO iPhone 6 Plus Case
In addition to Alexa XT, the 7 speed stress scenarios also have used the United States produced RED Epic camera. RED is youngest of cameras manufactured brand, in 2008 launched its RED is One of the earliest 4k cams. Epic is a 5k camera sensor size slightly larger than the Alexa XT, but tolerance is only 13, and color than the latter. Epic advantage in addition to high definition, there was the fuselage is relatively light (weight is only 2.1kg), and has a slow-motion shots of the Supreme 1080p/300fps. Many films are mixed use of Alexa and Epic cameras, different scenarios using the most appropriate model.
Lens
And SLR film camera lens are replaceable (except for the small GoPro). Most professional cameras use one PL lens mount, not like SLR manufacturers restrictions. Movies don't use autofocus, so movies are almost all manual focus models. The speed stress 7 uses a Zeiss produces MasterPrime series of Prime lenses and France Jean Optimo series zoom lens. Weight of a MasterPrime lens 2.5kg 16-135mm models all T1.3 maximum aperture, no respiratory effects in focus and aperture to adjust the promise. Optimo zoom lens's weight has reached 5-10kg, maximum aperture throughout the zoom fix. Film resolution, color indicators alone are superb, even Jiao TOU have similar and Prime quality. In contrast, the SLR lens even high-end models like toys, price difference is not the least bit (a 50mmMP prime lens sells for about US $ 30,000).
Film industry to shoot a moving picture, using the device and also on the tall. Although in recent years there has been a lot of cheap cameras and film, but they are still more expensive than our common DSLR. In addition to cameras and lenses, making movies using a variety of accessories, lighting, recording and later devices are complex and expensive.
Now you understand why "mobile movie" is just a gimmick. Masterpiece like of the speed stress 7 If using a mobile phone or regular camera to shoot, it becomes a cheap farce. Unable to determine the value of art works, but good equipment is necessary to shoot good movies.
