Canon 28mm f3.5: Vignetting

I do on digital and then I also shoot this on a crop sensor like a CL camera and I can probably shoot that at F4 and be happy with the edge sharpness and what about vignetting yes this lens does vignette really heavily wide open it 2.8 and it does reduce as you stop down but if you don't

subject enlarging it by 1.2 times this is a photo made using normal mode and this is super macro mode with the 1.2 x magnification an interesting feature but there is still one more let's see the led lights by pressing the button once the leds are turned on at full power press it again for 50…

points of light in your images get smudged particularly at wider angles this picture was taken at f1.8 and on a fullframe camera in the corners you can see that bright point of light to look really smudged out which is annoying for nighttime photography stop the ls down to f2.8 to rain it in again…
