Tecno announces a periscope telephoto lens that tracks photographed objects on its own.
Periscope telephoto lenses started making their way to smartphones in 2019. Today’s phones are easily able to generate a 4-, 5- or even 10-fold optical zoom.
However, this technology has a side effect. The larger the zoom, the harder it is to keep the subject in the frame. At 10x zoom, a gentle movement of the hand is enough for the photographed squirrel to fly completely out of the frame.

Some manufacturers are trying to overcome this problem digitally. Samsung Galaxy S21 Ultra and S22 Ultra begin to stabilize the frame after exceeding the 20x zoom.
However, this solution has a serious limitation – it starts working only when using the hybrid zoom, when part of the matrix is unused. The 10x zoom is completely optical, so the software has no way to stabilize the frame.

The Chinese manufacturer has announced a periscope telephoto lens called the Eagle Eye Lens, which uses two movable prisms. They are able to correct the flow of light to the matrix by up to 10 degrees.
Tecno argues that the Eagle Eye Lens technology will be perfect, for example, when photographing or filming moving cars. The phone – thanks to moving prisms and artificial intelligence – is supposed to keep the vehicle in the center of the frame by itself.
Rotating prisms are also supposed to function as optical image stabilization and eliminate hand shakes more effectively than the moving lens itself.
Tecno announces that the Eagle Eye Lens will go to the first smartphones next year. Smartphones of this brand are not available in Poland, so it’s just a curiosity for us, but it’s nice to see that some people still see room for improvement in even the most advanced technologies.
