Hi,
I expected to get a Green Flash ¿ but ?
¿ is it one or just Chromatic aberration of my Canon EF 500mm f/4 lens + 2X Telextender ?
¿ Hint of Green Flash ?

Re: ¿ Hint of Green Flash ?
Chromatic Aberration is usually purple though I have seen some achromats have it in the red. Never green. I vote yes. Green flash!

Hi,
Thanks for the yes votes and thanks a lot for the SPoD image again
I was uncertain if it was one and yes, now that James mentioned chromatic aberration is purple I agree.

but here a Canon lens has a green one
