Canon 7D - The magenta halo issue around bright lights

Is there any efficient way to get rid of the magenta halo around bright lights?
[For both photography & video on the 7D]

The latest 7D firmware update 1.2.1 does not solve this issue.

That is a lens issue, chromatic aberrations are a result of lenses, and the 50mm 1.4 is notorious for this wide-open. If you stop the lens down, this should go away at some smaller fstop.

That being said, the 7D does have more pixels on tap to record the CA, so just due to resolution alone, at 100% viewing, you may see more than previous bodies. since they had fewer pixels on tap. If a previous camera had just 2 rows of pixels to record this, the fringes would get averaged into those 2 rows, but the 7D would have 3 or 4 pixels to fully record this.

Thank you for your words my friend.

The thing is that there is an amound of magenta halo even when i change lenses.
Not so huge like the 50mm 1.4, but is there.

Moist air (halo) and artificial lights...could this be a wb issue? Either way, I think it looks pretty cool.

Don't know.. is your white balance off? It's obvious the exposure is set to capture the boat/ship at night, which means any light would have a halo because the light would be blown-out (over-exposed). If the light was not suppose to be magenta, then you just need to adjust your white balance to make it the correct color. It won't, however, remove the halo because that's just over-exposure.

It is chromatic aberration. You won't eliminate it until you can bend the laws of physics at your will (and eliminate diffraction). Different wavelengths of light diffract at different angles. Short wavelenth = larger angle, which is why purple is the prevalent color.

The diffraction is more visible around areas of high contrast. Shoot your 50 f/1.4 wide open on a sunny day and you'll see what I mean.
