Mobile phone accessories never lack of all
kinds of geeks goods. Goodscool will introduce some iPhone
5 Focal Lens Cameras which can keep the cell phone lens "bolder
and longer". They called mobile phone telescope.
Please understand its function correctly.
They can set times optical amplification (not change times), telescopic, manual
focus (but can't zoom). If we want to use a mobile phone telescope to make high
quality photos as SLR camera lens, that is impossible. Also we don't count on
it can compare with professional SLRS professional telephoto lens.
Once again, they are a fixed ratio of
optical manual focus telephoto lens, not a gradual/variable times (optical
variable times) telephoto lens.
