I purchased a 50mm F1.4 lens from B&H. It was not advertised as grey market. Looking closely at the web page it says "imported" but then all Nikon products are imported from Japan, so that didn't trigger an alarm with me.

web page that the lens was purchased from:
http://www.bhphotovideo.com/c/product/97413-GREY/Nikon_1902_AF_Nikkor_50mm_f_1_4D.html

Yet when attempting to register it with Nikon, I noticed it does not have a serial number. Nor was there a warranty on the included paperwork. It says "made in china" on the lens. No warranty no serial number. It must be a grey market lens. And I don't want it. I have requested a refund from B&H. I will advise the results, here.

Yes, I emailed them and this was their response.

Maggie,

Thank you for reaching out to us. I wasn't sure on this one so I talked to a few of the production supervisors to see if this was in tolerance or out of the ordinary enough that we would consider it a mistake. After looking at the images they said this didn't really look abnormal or out of line. It would be hard to compare to other labs since we wouldn't know which types of materials they're using and how tight they're stretching their canvases. I do apologize that you're not happy with it! My concern is that if we remake this for you, you still might not be happy with the out come. Let me know if there is any other information I can provide!

I have been taking pictures since the 60's my first good camera was a Pentax 35mm. I used it all over Europe when I
was in the Air Force. I bought a 2x extender to help my 105mm lens bring things a little close. I actually used it more for
a close up lens, I thought it worked better for that. About 10 years ago I upgraded to a Pentax K2000. I was pretty happy
with that but I thought my old 35mm actually did a better job. About 3 weeks ago I upgraded again to a Nikon D5600
and love this camera, the pictures are great. I travel out west frequently and would like to have a telephoto lens of
about 500 - 600mm. They are pretty pricy $1300 - 3000. I'm not a professional and take pictures as a hobby. I have
been looking at teleconverters. I see that Nikon has a Nikon AFN-S Teleconverter TC-14E III 1.4. That would bring my
300mm to the equivalent of 420mm. Has anyone used a teleconverter? My main problem with my old 2x was that things
were a little grainy. Right now I'm just investigating my options. I would appreciate any feedback before I go further
with this. Thanks
