Ok this sounds an easy one but.... in order to buy the 300 2.8 I would have to sell my 100 400 which is a good copy. This would mean my Kit Bag would consist of a 7D and 24-105 and the 300 plus a couple of converters. Would I miss the lightness of the 100 400 and it's flexibility or would the the focus speed, sharpness and ability to give a 600 5.6 with converter out make it a better choice.
