Canon or Sigma 15/2.8 fisheye? Need help

[Canonic]

Hi, folks,

Which fisheye lens is better for a full-frame DSLR Canon camera? I hope distortion is nearly the same (and it's a motivation for me to purchase this intriguing lens)/ But what do you think about contrast, color saturation, aberrations and bokeh (even wide open)?

Price is not an issue, I do care about optical quality.

both are good, but I think the sigma actually pulls the lead. check fredmiranda.com/reviews for alot of reviews of each.
