I just discovered your site and forum. I am just learning what this camera can do. This is going to be so helpful and educational. Thank you for your simple, easy to understand teaching methods. ;) I currently have an 18-200mm zoom for my D5100 and would like to take portraits of our new grand baby as well as get professional looking group shots. I also love to take shots of my garden and the chickens. Can you advise me about the pros and cons of the 50mm vs 85mm? I realize the 85mm is quite a bit more expensive, but it's worth it to me if it will give me better shots with less distortion. Thanks so much.
