• UPDATE



    The forum will be moving to a new domain in the near future (canonrumorsforum.com). I have turned off "read-only", but I will only leave the two forum nodes you see active for the time being.

    I don't know at this time how quickly the change will happen, but that will move at a good pace I am sure.

I've seen lots of comparisons from Sigma,
Tamron and the Canon f1.2L but nothing noting how the new Canon 1.4 L compares to the 1.8. Obviously the IS and slight f stop difference but what about CA, vingetting and sharpness?

Anyone have both lenses?
