I was pretty stoked to test out a new 500mm f/4 Cat Lens by Nikon a few weeks ago.
It came neatly tucked into the standard Nikon hard-shell travel case - it arrived undamaged and ready to use.
It was a little unwieldy and the balance was more towards the back. It took good pictures in normal light - but due to it's "cat eye" vision - it really upped my game in low-light situations.
I give this lens a 4 paws rating. It's the cat's meow... :-p
