Isn't there a lens on the micro-sheet to take pictures?

Micro-sheets can also be imaged without a lens.

As long as it is enough to ensure that the projection (that is, the image) on the photosensitive unit can be clear and obvious, and it does not exceed the dynamic range of the photosensitive unit. If there is a lens, then the lens plays this role; If there is no lens, then there is a way to achieve this effect, and that is pinhole imaging.

Analysis from the perspective of photography;

The micro-single is compact, light and beautiful, and has complete basic manual functions. High-end micro-sheets can meet the requirements of quasi-professional photography. 20 13, Olympus E-P5, Panasonic GX7 and other new micro-single, shutter speed ISO 100, 1/8000, the performance is gradually close to SLR.

The body of the SLR is bigger and heavier. High-end SLR is better than micro single in performance. At present, the continuous tracking and focusing ability of micro SLR system is not as good as that of SLR, but the speed of single focusing ability has reached the level of high-end SLR.
