I agree I didn't see much difference either outside of color cast, and I don't think the breathing was as bad as previously stated obviously not as good as the CP2, but for the price it's a not a bad lens.
IMO any time you need to add "for the price" we are talking about something crappy that needs to be justified. Don't get me wrong, I use that expression all the time too. But basically that's what it means.
I think the CP2 in that test looked much better. Trully visible difference and not only color. Like somebody already said, for the same price I would choose the CP2 any day. The thing though is that the Cinealtas are as good as CP2s and with the sale Sony is running costs less than these low end Samyangs. That is the real bang for the buck and lesson to take away here.
