Then show them the picture you show here, they might be able to do a partial refund or something. Contact them and be polite.
What it looks like to me is oil from the diaphragm too, is the diaphragm working smoothly?

I have the same lens - really like the bokina. You got a much better price for it... I paid £200. My copy has a very tiny bit of fungus in the rear element which I've kept under control thus far. I'm afraid I'm not sure what that is. Doesn't look like fungus though. Snap some more shots and if the pictures seem ok (which they do) maybe you should just keep it. Contact KEH to see if they would consider refund you some of the money since it was falsely advertised as ex+
If you decide to keep it (I think you should) make sure you get a hood to up the contrast. It's my special lens on the old NEX 5.. fungus and all

Can you close Tokina at f22 or f32? I have a Tokina 90mm but I can't close more than f9.I have the same lens - really like the bokina. You got a much better price for it... I paid £200.

One of my cameras' lenses had a weird spot right in the center. After a lot of looking at different angles and both ends, I had to conclude that it was a weird reflection/distortion caused by the lens itself -- there was no pool of oil. And it does look like the aperture might have a bit of oil on the blades, if I recall correctly, but it was all an optical illusion on the lens itself. Go figure!
Anyway, I can't tell from Fumanchu's photo whether or not there's a problem.

I see scratches on the front element along with the whatever it is. I would think KEH would do a bette job of rating the glass. This looks more like Bargain assuming that is oil or something similar behind the front element. Tt stinks that the KEH would misrepresent the quality.
Likely KEH will make it right, they have been around a long time.
'Mechanically like new, glass very clean.' Does that describe you lens even without the spot?

Looks like oil to me as well. Giving KEH the benefit of the doubt, it could be a result of international shipping, who knows. They are known for working stuff out, I would do as the previous poster suggested and start with a picture of the defect and see what they can do.

Shine a flashlight through the lens from the rear at different angles till it makes it glow, then try another picture.
Whatever it is it doesn't look good, return on their dime for full refund inc shipping.

That really disappoints me. KEH shouldn't have rated that EX+!

a few months ago keh sent me an ex-rated oly 24mm, that had multiple issues... the glass hadn't even been cleaned correctly; basically a bunch of rookie mistakes, that any competent tech should have spotted.
i returned it on their dime, and paid more for an an ex version, that was spotless, but mildly decentered.
not impressed with keh, and i certainly wouldn't recommend buying anything from them if you are overseas.

keh has gotten a lot of good feedback in the past, so i'm not sure what has gone wrong recently.
imho, i think that part of their success is due to buyer ignorance; most of us simply don't know how to inspect a lens properly... that, and most of us shoot with crop sensor cameras, which are far more forgiving, when it comes to issues like decentering.
the flashlight suggestion that lightshow made... you can use that for multiple things, including inspecting for haze on some of the inner elements, by angling the flashlight vs. lens at just the right angle, so that it reflects off of the inner element(s).
even if everything looks good with a visual inspection, there can be errors that only show up when you take the picture... how many of us truly know how to shoot the right type of test shots for that?
based on my limited experience with the a7r, the majority of prime lenses out there are less than perfect; some brands have worse quality control than others, and even with perfect quality control, every camera brand has a few lemon designs in it's lens lineup.
i think that you have to identify the weaknesses, and learn how to shoot around 'em, by picking the right glass for the job, and/or putting the oof areas out of the area of interest, in the picture.

Looks like residue from condensation. I doubt it will affect your photos much if at all. Still should be clear for EX+, contact them
