Dolina... they are really great photos... showing (off!) very well the wonderful poential of that lens.
Thanks for sharing... good job on them. I love the colours and depth of field you've used. Will look at some more of your photos on flickr when I have more time (I'm in my lunch break at work).
McTool - welcome! I really like your bird shots with the 500L too. Autumn a bit over a year ago (March 2012) here in in Adelaide, SA, I took several photos of Wattle Birds, New Holland Honeyeaters and a Willy Wagtail - that patiently allowed me to get quite close to them. I had my 70-300mm L (so won't post on this thread). I was happy how many BIF of mine worked out.
Thanks for sharing all, and I look forward to more photos from Canon's amazing 500mm L f/4 L lens. I would be very tempted to get the 200-400mm L f/4 1.4x lens for wildlife & birding, I think it would do a great job (I love the flexibility of zoom lenses often when outdoors taking photos of aspects of nature - eg landscapes, wildlife, birds, etc).
