I agree, that is an excellent use of selective coloring. And everyone's put forth a great set of images - this is such a seductive lens!
I can report it does pretty well on a film camera as well. But it really shines -for me- at the close-ish portrait and product shot range.
Funny: if you do an image search of the Env phone, you'll get pics of my daughter holding her brand new phone, taken with a DA 70
These were some of the first pics I took with my then-new birthday 70 as well, the learning curve isn't very steep with this lens on digital
