These look great Bill - and your only just starting to get the hang of this lens.
Love the colour in #1. Mongo's favourite is #3 for clarity/sharpness/detail, subject matter and framing. Very nice use of DOF.
Mongo was very keen to see how to did with BIF. You seem to have had no trouble acquiring and holding focus. That is an excellent start.
You must tell us a little of what you think of this lens overall when you have ad an opportunity to have a really good trial with it. So far, it looks very good indeed.
Thank you Mongo. With your skill and experience I regard this as the highest praise.
Interestingly, the duck's colors in #1 are muted compared to the original (legs and beak should be the same and the brown feathers had more red in them) but my LR skills still fail me.
I too found #3 to be the best of the group in terms of overall sharpness, etc. which was a bit of a surprise as this was in twilight with auto iso pushed up to 3200. The only explanation at this point is that, being left eye dominant, I was able to cradle the lens in the crook of my left arm which added an extra degree of stability even with the VR on. That and a good deal of serendipity.
The one issue I have with the BIF's is that I have yet to figure out how to maintain really good focus on the head/eye area (with body still in focus) without stopping down a good deal and pushing the ISO into the noise realm.
