Shot just before 8.00am early on, whilst monitoring these two owls and as previously stated the nail & bird poo has been removed, but for those who have asked how far have I gone in ISO with the MK3, well here you are, ISO8000, but have also gone to 10K with similar results. The files are good and in the fluctuating light we have over here, like the MK2, I have absolute faith in what it delivers, but the mirrorless aspect as mentioned before does mean the subjects get far closer and often catch me out. Both owls don't really bat an eyelid if the camera is set to 'conventional', but to date, I am shooting more in silent mode. The image is certainly not going to win a prize and yes, the cobweb strand could go, but noise has improved above 64000 (NR was applied simply via LR at only 7, 4, 4,). With hindsight removing the 1.4x would have been better, but under the bag hide it was too difficult.
Thanks to those who viewed or commented on the previous posting.

Note: The subject is fully wild and completely unconstrained. Besides the potential impact of my presence, nothing has been done to intentionally alter or affect the ongoing behavior of the subject and, of course, there has been no use of any form of bait or other form of wildlife attractants (including vocalisations) in the capture of this image.
