With Panasonic's Nano Surface technology the reflection is dramatically minimized at entire visual light range (380nm-780nm) by applying the extra-low refractive index coating with nano-sized structure on the surface of the lens. It results in the super clear picture with dramatic reduction of ghost and flare.
Due to the shallow depth of field which is unique to the large aperture lens, even a slight handshake causes out-of-focus. However, the POWER O.I.S. (Optical Image Stabilizer) which is newly integrated in this lens effectively compensates for not only small, fast movement but also large, slow one making it easy to shoot super clear shots even when shooting in low-lit situations such as in night time or indoors.
For the lens distortion compensation available, the horizontal axis of MTF is the distance from the center, which is compensated accordingly.
