I see your point ;-) Flaring with the Sigma (which I use as well) can be sometimes quite bad. Few solutions - use the removable "lens-cap" (the barrel thingy) on it. If it vignettes in the corners, file them away a bit. Works well (but still will show big spot of defocused flare with some bright lights). Good light! fra
