Any Camera buffs out there? Looking for Christmas ideas. My wife has a Canon 6D with a 50MM L 1.2 lens, which she loves that set up. Debating getting a 70-200 L 2.8 IS II or 24-70 L 2.8 II. Both are similar prices. Leaning towards 70-200 to give more options since she 'walks around' with 50mm and loves it.
