Hi Folks, It's a difficult choice to have One Lens throughout the year. I brought Sony 200-600mm F5.5-6.3 Sony 70-200mm F2.8, Sony 24-70mm F2.8 & Sony 12-24mm F2.8 for various parameters & have been used quite often. They are all excellent in their different needs. I feel 24-70mm is good if you have only one choice.
