Good question. Why on earth WOULD you use a lens like that in bright light? It's a special purpose built low light lens.

You were clear. There are always special cases and enough other people have made the point that I concede there is an apparent need for slow films though I don't ever personally need them. But come on - shooting that lens wide open in sun? Why?
