Fun! Jon let me use his 500mm Sigma lens with a 1.4 extender, for a zoom capacity of 700mm. Yowser! Even on a tripod, I could see the image wavering just slightly in live view. I could only achieve f/9, so I bumped the ISO to 200. Shutter speed at 125. Hit the self timer so I wouldn't jiggle the camera. Cropped only a little.
