I was using my D7200 DX camera and internal 1.3 crop for a total crop of 1.95. In addition I decided to try adding a 1.4 T.C. as the light was good; thus giving an equivalent 35 mm focal length of about 1,100 mm. I was shooting hand-held, but was able to support my arms on a railing. The, as posted, images are cropped an additional 40% in P.S..
