My question, looking e.g. at:

http://farm2.static.flickr.com/1439/5140531441_1f50fe49cd_o.jpg

in the upper right corner, I see hefty chromatic aberrations.

I know that chromatic aberrations are automatically removed by Panasonic G1, even in Lightroom 2.

GH2 worse than G1?

Any explanations?



Thanks

Hello Lars,



I see that the shot you linked is from the new 14mm f/2.5. We don't know much about its optical behaviour but it might be one of its characteristics. The lens is a midget and I would expect trade-off and some of its aberrations to be bordering correctable. I can't speak for Panasonic's in-raw correction as I don't own a panasonic body but judging only by the 45-200, for which you have to max out Lightroom sliders to attenuate without ever fixing completely, I'd say such "can't do more" behaviour is likely on the 14mm lens.

So what we're seeing here would rather be a 14mm effect than the new body at work. Just my guess.



Greetings,

S.

Is that not Purple Fringing rather than CA?

Looks like a combination of both to me. Some PF (bright purple) and some lateral CA (darkish blue).



Kind regards, Wim
