It's assumption but the CA is consistent with other samples of the same lens and I've never got CA like that from simply shooting through window glass on it's own (which is optically simple, so unlikely to produce it like that under normal circumstances).

It's a lovely lens indeed and as you say, every lens has a degree of CA, I was merely commenting on the trend for manufacturers to accept the presence of CA in high end glass. Yeah it's easy to remove later (actually if you shoot jpeg then Nikon do it in camera, I presume Canon do too) but it being acceptable to them in a £1500+ prime just seems odd to me, that's all I was commenting on. It affects all the new fast primes today seemingly and doesn't detract from the lens being really quite something overall.

Mine also has pretty bad CA wide open, I think it's an unfortunate trait of the lens.

@raymond, congrats!
 
Very fast lenses always suffer CA wide open in certain degrees. It's more the problem of science rather than lens construction IIRC.

Filters do amplify the problem though, which is why I personally don't use them.
