Because I enjoy the 50mm F1.8 so much

so that I traded in for the F1.4 version.
But I used less than the F1.8 afterwards. ( I guess I got myself too many choices in the end )

Easier way to do a bounce card is using a white paper wrapped around the flash using a rubber band, it will work the trick, just make sure your flash out put is only strong enough to add 1-2 stops of light, so that the flash is natural.
