I've just finished my first serious job with the 180 and was a bit surprised by the results. My beautiful Bali skies have banding in them. Its very uniform too - 3 feint vertical bands - the first right down the middle, the other two equidistant from the middle and the sides. It is about a column wide with slight shadow a few columns wide.
I checked the sensor and see that it actually appears to be a grid of 6 sensors - divided in exactly the same way as my sky....
The banding is very noticeable in Lightroom. Its is quite hard to spot though in C1 - as though there is an algorithm to conceal it - although it is still noticeable on 100% crop whilst moving the image (before it appears to be dithered).
I'm on a laptop so I'm struggling a bit to visualise/assess whether this would be visible in large prints when processed via C1 (my usual workflow). Lightroom clearly isn't viable.
Have others seen this effect ?
PS: Aside from this, the 180 is phenomenal - so this isn't a bashing thread - just trying to figure out what this banding thing is and how to work around it.
