His name is “Crypsirina temia” which I have photographed many times.
But I must say this is first time I see such detail of his feather, that’s amazing.
This is the another picture taken D500 with the same AF-S 300mm f4 (Light condition is poor !!)
As a previous owner of D750 and D810, I am shocked by the leap in quality of image that D850 gives. This is not only about an increase in pixel but a revolutionary advancement in sensor design; D850 has equipped a Back-Side Illuminated CMOS Sensor for the first time in Nikon DSLR.
The image quality still maintains even though a tele-converter TC14 is applied. These shots are taken by AF-S 300mm f4 with TC14.
Post-processing is not quite needed, just some minor adjustment in exposure will be good enough.
This combo seems to be capable to handle flower photography too.
Will certainly test more soon.
