Some images with the 7D + 1.4 extender. The 70-200/II and 7D auto focus are a match made in heaven. When you put the 1.4 extender..not so any more. The auto focus becomes notably sluggish and is far from ideal for BIF photos. Slower or more stationary targets would be OK though.
Just some seagulls shot from my balcony:
The 5D2 with the extender is a lost cause. Its auto focus system is slow to begin with but when you put on the extender it becomes so sluggish that the fastest things you can photograph are geological formations. Plants typically grow faster than that combination focuses
