Price includes the shipping and is net to me. Only possible trade of some sort would be an Aquatech or Nauticam housing for a7r3 or a like new a7r3 body. Check my other posts for other items, selling off all my Canon equipment. Have bought and sold tens of thousands here with no issues, buy with confidence!
So the issue with this lens (and reason for the low price) is the front element. It's in excellent condition except for that, it will likely need replacing at some point and is hopefully priced appropriately. I was using it for portraits as is, and can provide some samples if you'd like to take a peek. It seems to reduce contrast somewhat, but was usable for me.
Includes the box, both caps and hood. Can throw in an extra rear cap and body cap.
Please let me know if you have questions or want more pics!
