Zoom lens
Optical zoom lens – Image is magnified by lens 3x, 4x, 10x and more, but keep in mind that long zoom very prone to motion of the camera. Use a tripod to cover up this problem. A 3x optical zoom means you can make an object appear three times closer. Optical zoom produces the best quality images. You can not get too close to the object, but after a photo-editing software can help you crop the image. Is given better result than with the digital zoom.
Digital zoom Optical zoom is a simulation, but increases only the central part of the image. The lens is not used in this case. The digital zoom effect is given by the software inside.

With changes in the speed sensor and / or lens focal length, change the tracking number. So instead manufacturers specify the maximum range of the flash with the assumption that flash is fully charged and the target opening is fully open.
