Great pic BTW. Large frame AND high resolution. Can't beat the combination.

Hi'ya Brat!
No Chromatic abberation...what sacriledge

this is an AP my man

and a small chip as far as the design of the AP 4" FF specs go
What you are noticing, particularly in a couple of the corners, is a tad of colour frame missalignment which, yes, is more difficult to deal with at this chip/field size...I didn't notice it until well into the processing and by then was not interested in going back and tweeking the sub alignment registration...cause it was late and I am a little lazy

...just ignore it
I agree, 1300mm FL with 9 micron pixels is pretty well ideal I recon?
