This is a cropped view of a Gray Squirrel's right eye showing the reflection detail. If viewed in original size, you'll see the house and the opened bathroom window and in the right corner (as viewed) there is a round shaped form. This is the lens hood on the lens pointed out the window. This Gray Squirrel was imaged on the deck railing in rural upstate Columbia County, New York, USA, on April 03, 2011. I have added the original image below. I was using my manual focus Tamron Adaptall-2 model 60B SP 300mm f2.8 lens and Tamron Adaptall-2 140f 1.4X flat field teleconverter with attached Tamron Adaptall-2 Pentax K A mount and Pentax K20D camera body, hand held, manually focused. Note: With the teleconverter attached, this lens was functioning as a 420mm f4 telephoto.
