Both lenses are now out of stock at B&H.
B&H has notified me that they now have the new highly anticipated 300 f/2.8L IS II and 400 f/2.8L IS II in stock. They note they are both in limited quantity.
Buy the EF 300 f/2.8L IS II here $7299
Buy the EF 400 f/2.8L IS II here $11499
Are they any good?
Both will probably be slightly better than the 18-55 pre IS.
EF 400 f/2.8L IS II Unboxing
I don't normally post unboxings for a few reasons. However, things are slow and there are new cases and lens caps to show off. So here is the 400 f/2.8L IS II coming into someones life.
When will Canon Rumors have them?
I have the 300 f/2.8L IS II on order, however I don't think the 400 is in the near future for me. I'll have one in the spring.
