During todays lesson we had been given the opportunity to get to know some of the equipment that was on offer to us when it would be time to film or thrillers…
We learnt the basics of using a tripod, including setting up the frame and adjusting the length of each individual leg, to achieve a perfect height, we also discovered the leveling bubble can be used to make sure the tripod head is level.
The three cameras we learnt how to use, were the Cannon 5D Mark III, a DSLR with a very compact body and relatively easy to use if you have used any DSLR in the past. It uses Canons own detachable lenses system and so in order to use some sony e-mout lenses an adaptor is required. It had fitted a prime lens, with an aperture of 18mm (focal length). It is a fixed lens that cannot zoom. This is beneficial though, when you know what aperture you want before hand and using a prime lens really boosts quality. Although this may be unpractical as many lenses may be required to get different shots. One very unpractical part of the prime lense, is the fact that is cannot use extended zoom to get a true focus. In order to achieve true focus on a prime lens you have to measure the distance between the subject and the sensor in the camera, then dial that into the camera itself. Overall though the Canon is a discrete and high quality camera that can be used for a multitude of filming needs. For run and gun filming you can’t beat the compact body and ease of use. However I personally would change the prime lens to a 18mm to 55mm zoom purely for quick focus and the ability to create shots with shallow depths of field.
Moving on to the Sony NX5, the oldest of the trio. An all round okay camera, that is very large and not too impressive on the spec side of things… It does have XLR inputs so boom mic's and other audio equipment can be added. But with a fixed lens and only being able to record 1080p at 25fps or 50i (50i = fake (digital 50fps)) The only way to achieve true 50fps is in 720p. It also uses a Sony G-Mount lens. And a Sony Sensor unlike the Canon the Sony sensors are considered some of the best for high bit rate images and can encode in RAW (loseless) so less noisy images. White noise can be set using the colour reference numbers or but the white balance function. That requires a object that is completely white. Focus and exposure can be adjusted using the standard lens rings. And the G-mount lens does have zoom. 20x optical (high def) and it can also digitally extend x1.5. So when setting true focus on a subject no measuring is required just human eyesight.
