I captured this Prothonotary Warbler, one of the most colourful and rare warblers in a swamp in Ohio.

Not too indistinguishable from the bare lens if you stop down a touch. Really hard to tell the bare lens and 1.4x apart at f8, and even 6.3, 7.1 are very sharp. Never liked it wide open at 5.6 though, not sure if that's typical or not.
