Universal Mobile Phone Telescope - 6x zoom cell phone telescope

Said in principle, mobile phone telescope, is a kind of the hand-held monocular telescope ruled out the normal focusing function. So, not suitable for use with eye, can only be used in mobile phones.



The reason for not include focusing function is very simple, that if we adjust the focal length - cell phone camera is not autofocus, and that the image will appear blurred.

Talk about the meaning of fixed focal length, in the digital camera lens, the fixed-focus means that the enlargementfactor can not be changed when shooting - in the telescope, this is not called "fixed focus", this is called "fixed zoom"! Note that this distinction.

In the telescope, fixed-focus refers to the very low-grade, there is no focusing mechanism on the product, such products are rare. Adjust focus refers to the sharpness adjustment, the general product by formal manufacturers will equipped, unless it is too low-end.

(On the telescope, as opposed to changeable zoom, corresponding called "fixed times."
