It is a cropped image (cropped around 10%) as I didn't do any flat field. You know canon camera has annoying shadow of mirror casting on the sensor ,and flat field is a must. There is minimal vignetting at the extreme corner, may be due to the camera ring (48mm still no big enough for FF) .
BTW, It is just a test shot for my Dell tablet. [微笑]
