This isn't much, but considering what I used to get it, I'm thrilled.
Cheap Quantaray 500mm f/8 lens with a cheap Albinar 2X teleconverter attached, handheld from maybe 15 to 20 feet away. Unresized, slight cropping (so I could level the wire) so if viewed in full it's pretty darn huge. I'm pretty certain I was stopped down to f/11 or maybe even f/16 when I shot this.
The EXIF lies, it was actually a 1000mm equivalent (1500mm when you add in crop factor).
The 500mm and 400mm sibling I have of these lenses are nice because they're stupid-light, but shots like these don't come easy or often, they're crazy slow and even worse if I have a TC attached.
