Purchased from B&H.
Did some tests and was quite happy with all aspects of lens until I did some outdoor shots. Then I realized the lens was de-centered (and easily seen up to F11). Three Quarters of my images were perfect, even at f 1.8. If I had paid $ 499 for this lens then I would probably keep it. But at double that...no way...
Sending it back for a refund...Will wait till year end to repurchase or see what other FE primes come out by then.
Make sure you check your copy if you have one or buy one. The A7/R images forum has others with similar issue.
