This is a superb lens if you want a fast wide. I've had two copies of this lens and can highly recommend it. It's one of those items that if you've ever used one you'd understand why they are so prized ...
Alas I just sold mine again this weekend but only under the duress of a part exchange on a Leica Noctilux. I'm sure I'll end up buying another at some point.
BTW, the HN-31 in the pics belongs to your 85/1.4. It'll vignette terribly on the 28/1.4.
Good luck with the sale. These really are keepers folks.
