Nikon D4 600F4 with 1.7 TC @F8 1/1250 ISO 1000 +.67EC
I am usually not a fan of using Teleconvertors on lens as it normally softens the image. I did not have much choice tonight as I did not want to disturb this owl and it was all open ground between it and me and a stalk was pretty much out of the question. I switched to using Auto ISO with ISO200 as minimum and ISO 10,000 as maximum with threshold shutter speed of 1/1250s.
Until next time
