How the "King of Machines" is Practiced —— Deep Analysis of Sony PXW-X280

PXW-X280 belongs to XDCAM family series. Three 1/2 inch Exmor CMOS full HD sensors are used, with sensitivity of F 13 and signal-to-noise ratio of 58dB. Jianghu people call it "Machine Emperor". XDCAM is an important series of Sony. Since the first machine was introduced in 2007, the title of "Machine King" has been following this series.

In 2007, the first product of this series, PMW-EX 1, was released. Sony used three 1/2-inch sensors on this camera. In June 2009, 1 1, the "second generation" PMW-EX 1R was released, adding DVCAM and HDMI；; 20 12 "third generation" PMW-EX280 has a smaller body and has added MPEG HD422；; In 20 14, the XDCAM family has evolved to the "fourth generation", which is our protagonist today, PXW-X280. In terms of innovation, PXW-X280 has many remarkable features, including dual SxS memory card slots, buffer recording function, "slow motion and fast motion" function, 3.5-inch QHD (960 x 540) color LCD screen and 17 times Fuji Dragon professional HD zoom lens. Next, let's take a closer look:

First of all, PXW-X280 continues and optimizes the adoption of three 1/2-inch Exmor? CMOS imager has achieved high sensitivity and low noise performance, which is very noticeable among similar models.

Secondly, in terms of format, it supports multi-format recording, including high-definition XAVC Intra and XAVC long GOP, as well as MPEG HD 422 50 Mbps, MPEG HD 420 35 Mbps, MPEG IMX and DV.

The newly added 17 times Fuji Dragon professional HD zoom lens has a zoom range from 29.3mm to 499mm (equivalent to 35mm). The lens has three independent control loops with physical aperture, which can control focus, zoom and aperture more accurately. For photographers, it also has a special practical place-pxW-X280 is the only camera of its kind that uses mechanical aperture. The aperture ring has a scale and a physical aperture, which is similar to the operation feel and accuracy of the shoulder-mounted camera lens.

In addition, new professional functions, including dual SxS memory card slots for synchronous recording, cache recording and "slow motion and fast motion" functions, have been widely praised by professionals. The PXW-X280 is equipped with two SxS memory card slots. Two media slots support recording in "Synchronous" or "Relay" mode. "Synchronous" mode allows recording on two memory cards at the same time (firmware upgrade is required), while "Relay" mode can automatically switch from the first memory card to the second memory card when the first memory card is full. Cache recording can be set to 15 seconds to avoid missing key shots. "Slow Motion and Fast Motion" can select the recording frame rate from 1 frame (fps) to 60 fps in 1080P and 720P formats to make high-quality slow motion or fast motion images.

Generally speaking, X280 is continuously optimized and improved after three 1/2 inch sensors. Its function is very competitive in the current camcorder, and it is worthy of the title of "king of machines".
