Meantime some shots over the weekend for your comments. Shot on a Kenko Pro 2X for the woodpecker and Black Crested Bulbul. Cropped, sharpened and converted from raw to jpeg for both. Contrast and brightness adjusted for the woodpecker.Prime 600mm for the Pigeon. Too excited and forgot to put on the TC. Cropped, sharpened and converted from raw to jpegWoodpecker >> ISO 200, 1/80 sec, WB:Sunny, Aperture PriorityBlack Crested Bulbul >> ISO 200, 1/200 sec, WB:Auto, Aperture PriorityThick Billed Pigeon >> ISO 200, 1/800 sec, WB:Sunny, Aperture PriorityOne issue I noticed from the EXIF data was that focal length : 600mm & focal length in 35mm : 900mm.Why is that so? If the lens is 600mm FL, without TC will still be 600mm and with 2X TC should be 1200mm excluding "Whatever magnification factor" from the extension tubes. Need your enlightenment.tbc</blockquote>
