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

PS love the off centre composition.
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?
