Why do you prefer the "trombone" version of the 100-400 L? I have that version and was thinking I was slumming some inferior goods.
Also, what about the difference in the 7D and the 70D MKII? I have not seen it, but have heard the autofocus is superb.
Do you shoot in RAW? What to you use to organize your photos? (Sorry for interrupting the flow of insults on here.- Free free to carry on)
