Canon 100-400 IS USM zoom lens for sale. With soft case and full packaging. A few scratches on the lens hood, but the lens itself is immaculate. Brilliant starter lens for wildlife and sport.

If you read my first post on this thread, you'll see why I started it. So, after reading your advice, I lined up a couple of alternative programs (Affinity Photo & Pixelmator), but didn't buy them yet.
