Why can the shooting time of Canon 60D SLR short film only be about 20 seconds?

There are two restrictions on the single shooting time of SLR video:

1 and SLR cameras have limited single shooting time. The EU has different taxes on cameras and camcorders. In order to prevent some manufacturers from exporting cameras with very powerful camera functions to Europe for tax avoidance, the single shooting time of SLR cameras is limited. If the SLR produced by the manufacturer exceeds this limit, it will be fined.

2. The speed of the card. If the speed of the card can't keep up, shooting will be interrupted even if there is no time limit for the camera. Shooting HD video requires 6 or more memory cards.

Product characteristics

1, rotatable LCD

The back LCD of EOS 60D adopts a rotatable mechanism, which can be opened horizontally, rotated vertically and adjusted in angle. When shooting in real time, you can adjust the LCD on the back to an angle convenient for confirming the image and shooting. For example, low-angle or high-angle shooting and portrait selfie can be easily realized through the rotatable LCD, thus experiencing different shooting fun.

2. Excellent basic performance brings the release of expressive force.

EOS 60D is equipped with a CMOS image sensor with an effective pixel of about 1.8 million, which can realize high-speed data reading and low-noise imaging.

3. A gapless microlens capable of improving light concentration.

The image sensor of EOS 60D adopts seamless microlenses, and there is no gap between adjacent microlenses, which greatly improves the light collection rate. In addition, the distance from the microlens to the photodiode is shortened. With the increase of light concentration, the signal-to-noise ratio is also improved and the imaging noise is less.

4. Adopt brand-new processing technology

In the semiconductor manufacturing project of CMOS image sensor of EOS 60D, a brand-new and highly integrated processing technology is adopted. The photodiode that converts light into image signal adopts a structure with high aperture ratio (photoelectric conversion efficiency); The transistor in the pixel is improved and the signal-to-noise ratio is improved. Noise is effectively suppressed, and the highest ISO sensitivity of ISO 12800 is achieved. Moreover, the highly integrated processing technology not only expands the dynamic range, but also brings rich hierarchical performance.
