What timing! Just got the new Canon EF 100mm f/2.8 Macro today and this little guy decides to find his way into our home. I should have taken a picture of my wife! She was hiding under some pillows after finding the bat.
The contrast is horrible, he/she landed on the area above our fireplace which is brown stained pine. The detail of the bat, however, is quite nice. He dropped down on me shortly after taking a few more pics at which point I showed him the door.
