In a previous post, I think you said you hardly if ever use the 70-200mm because you have the 100-400mm. So parting with it would be a no brainer. The question would then be what lens would you want. Ask yourself this, maybe even go back and look at what you have been shooting. When you have the 100-400mm on how often are you at the 100mm range. When you are using the 100mm as a telephoto how often do you need just a little bit more reach?


The 100mm is a fine telephoto with an IS system. Do you find it lacking in length as a telephoto?
