either my 24-70 2.8 or my 70-200 2.8
From Lightroom, 3885 of my 7987 keeper images from this year are on my 500/4. That's 49%. Nothing else has been used for more than 1000 images

If I had to choose a single lens it would be a 17-200mm F/2.8 IS, but unfortunately Canon have not relaeased that yet.
