Wonderfully Sharp f1.4 at a Fair Price
Having shot this lens extensively for a week, this lens is great!
It is surprisingly sharp at f1.4 with good bokeh and well-controlled CA.
I shoot it extensively on my D800, almost always at f1.4 and it never fails to impress.
Build quality is exceptional. The machined polished metal mount extends into the body making a very impressive first impression. The main barrel (and filter threads) are plastic, but the whole package feels high quality.
Adding an extension tube and shooting at f11 also gives great results.
