Colour casting from stock lens
Hi
I gess someone has talked about it. I have noticed a magenta/pink colour casting in the upper part of the frame and a greenish downside of the frame, mainly when the iris is wide opened. Is this a "special deffect" from the stock zoom lens or from the camera itself? Thanks Ron |
It's the lens. You can use the camera's "shading" feature to limit it.
|
CA : Chromatic Aberration, if you do a search on this form or Wikipedia you will find lot's of info about it.
|
"Lens shading" is only available on HD200 series cameras. HD100 series cameras don't have it.
You can also avoid this issue by closing the iris to at least F/2.8. The CA will be worst at F/1.4. |
Thank you all.
I ask myself if it worth buying the camera with this lens, even costing around U$800,00, with such big limitation, because I can`t (difficult) deal with depth of field and other situations. Regards Rona |

It is indeed the shading that needs to be set (CA has nothing to do with this, it's also no defect). On the HD200 you can set it (and therefore get rid of it), on the HD100 it is alas fixed.
You will notice however that the shading is aperture-related and the gradient will become invisible at F2.0 or more. It shouldn't be a problem in any real situation. I say all this, supposing the lens hasn't had any knocks and stuff... |
Thank you Werner, I think you got the point.
My lens is like new, no "knocks and stuff". Ron |
