Well i went out last weekend to photograph some birds, usually i use my 100-300 F4 but this time i decided to do something different, i decided to use my Pentac 10-17mm F3.5-4.5 Fish-eye...
yep thats right an ultra-wide fish-eye lens for birding
here is the gallery (it has a few other shots in it too)
