Has anyone purchased this?

I'm 90% sure it would be gray market but am willing to take a chance on that. More wondering if it is a complete scam because it is half price.

I'll put the link in a reply in hopes it doesn't get moved to links.

Note - it is AF-P, not AF-S, so it only works on certain cameras, according to KR, since 2013.

You might not agree with KR's expertise, but he does have quite a stockpile of information.

That's actually not sold by Walmart. It is sold by "Ted's Electronics" who is a dealer on Walmart's internet system. I'd say it's likely gray market considering the price point.

I don't know if this is a grey market lens, but if you expand the product description on Walmart's website and look at the summery specifications at the bottom, you will notice that they claim the 70-300mm DX lens gives the equivalent of a 105mm-450mm lens on a DX camera. Does that make sense to anyone?

Perfect sense - a DX camera is a CROP SENSOR camera, the equivalent field of view with any lens on a Nikon DX camera is 1.5 times the mm stated for the lens, so a 70 mm lens on a DX camera will be equal to 70x1.5 = 105mm field of view on an FX camera.

If you read all the specs it weighs 140 pounds and is 144 inches long. I think it would need two strong tripods.

I have the same lens it's not a dx lens as so many think , it works on a dx camera , I have had it for over five years , I bought when I seen
The write up by. Thom Hogan , he says it's a FX full frame lens , but works perfect on a dx also , and you have crop factor of
105-450mm , and if you have to ask does that make to anyone , I suggest you sit down and think real hard as to why it makes sense ,
I will give you a clue, 105 -450 mm , and at the time Hogan said it is one of the best bargens around ,and should be selling for
Twice the price of the $600 ,, because of the optics ,

You are not talking about the same lens. This is the New AF-p DX.

This is why information from the internet must be checked and double checked.

At the very least it's a good idea to read through the thread.

Yes. 1.5 crop factor.

This lens debuted last year. Note it is AF-P, not AF-S. It has a pulse motor. It will work with my D5300 but I need to update the firmware to be able to turn off VR.

My question isn't about the lens per se. It is about the deal.

Crap. It was moved to links anyway.

I saw that. Just asking if anyone actually got one from that link.

I think you have it wrong. The lens in question is a DX (crop) lens, not an FX (full frame) lens, and its real focal length is 70-300mm, with an image circle that is just sufficient to enclose a DX sensor. If you were to use it on a full frame camera that does not automatically limit the portion of its sensor used to that of a crop sensor, the resulting picture will be a circle, not a rectangle because the image circle of a DX lens is smaller than that of an FX lens.

If you use an FX lens on a DX camera, the sensor will crop the image to cover the same angle of view as a 105mm to 450mm lens. That is because the image circle on a full frame lens is substantially larger than the DX sensor's rectangular shape.

In any case, the focal length stamped on the lens is the true focal length regardless of size of the camera's sensor it is used on. If the lens is 300mm, it means that it will bring an object at infinity distance into focus when the rear of the lens is 300mm from the sensor regardless of the size of the sensor. A 300mm FX lens does not change its focal length to 450mm when it is used on a DX camera, it crops the image to the equivalent of 450mm because the sensor utilizes less of the area within the image circle. Therefore, a 70mm-300mm DX lens is 70-300mm on a DX camera and not the equivalent of 105mm-450mm as the vendor indicated in the add.

Most, if not all, Nikon DSLRs when they come out of the box default to DX mode automatically when a DX lens is attached. This means they only use an equivalent part of the sensor. This can be changed in settings.
