As a Sony Artisan at Sony Kando 1.0, I was able to play with the new Sony 100-400/4.5-5.6 G Master. I love the range an dbeing able to shoot full length and tight portraits easily. The lens is fairly compact for such a long lens and is crazy sharp! I was very impressed with the lens and I am looking forward to buying one when they become available!
