You would think that Nikon would know it wasn't a fisheye wouldn't you?
They must be dumbarses!

Doesn't look rectilinear to me.
Do you actually know what rectilinear means?

Yes I do. It means the entire image area (rectangle) is populated. If I remember correctly, the 10.5 is a rectilinear fisheye as opposed to a circular one, which is what I was referring to. I guess that it's another example of an oxymoron! If you have ever used one, it is way kool! Are we good now?

No.
That is not what rectilinear means.
Rectilinear means that straight lines stay straight.

What you are describing as rectilinear is simply a full frame fisheye.(not to be confused with a fisheye lens for a full frame camera)

http://en.wikipedia.org/wiki/Fisheye_lens
....Fisheye lenses achieve extremely wide angles of view by forgoing producing images with straight lines of perspective (rectilinear images), ....

.......The first types of fisheye lenses to be developed were "circular fisheye" lenses which took in a 180° hemisphere and projected this as a circle within the film frame.....

......Full-frame fisheye
An example of full-frame fisheye used in a closed space (Nikkor 10.5mm)As fisheye lenses gained popularity in general photography, camera companies began manufacturing fisheye lenses that enlarged the image circle to cover the entire rectangular frame, called a "full-frame fisheye".

The picture angle produced by these lenses only measures 180 degrees when measured from corner to corner: these have a 180° diagonal angle of view, while the horizontal and vertical angles of view will be smaller; for an equisolid angle-type 15 mm full-frame fisheye, the horizontal FOV will be 147°, and the vertical FOV will be 94°

Lighthouse is right. I have the Nikon 10.5mm. It is a full frame fisheye. A rectilinear lens is corrected so as to not have the bending lines of a fisheye.

My Nikon 70-300mm VR is auto focus. Did the older versions of this lens lack auto focus?

Although wikipedia is not the only source of definitions, I have no desire to carry this on further. You're right, I'm wrong. Guess I had useless teachers over the years. Does it matter? Same difference, different definition. My point still stands. If you want something wider than 17 on a DX, try 10.5. Call it whatever you wish, it's still wider than a 17.

IF the 70-300 is the newer VR with autofocus, I agree, keep it, that is a pretty nice lens.

A low cost version I am using and loving on my D7100, which is also DX, is this Tamron AF 17-50mm f/2.8 XR Di II LD Aspherical Lens (IF). $499 without VR,

or Tamron SP AF 17-50mm f/2.8 XR Di-II VC LD Aspherical (IF) Lens $659 with VR (VC).

You would sacrifice some image quality but have a very nice range just getting the 18-300 though. While it is a sacrifice, it certainly is passable, esp if you know the lens sweet spots and are able to use them. 17mm DX lens does allow for a pretty wide view, although it would not be classical WIDE angle.

I can post an image for a sample with it at 17mm if you would like to see the max field of view you would have. This lens has some very nice optics ratings, and I am loving mine, which I recently got. I chose the NON VR version

Yes it does matter.
You posted incorrect misleading information on which someone was making a potential buying decision.

Not the same difference at all.
A rectilinear lens is totally different than a fisheye.
Their definitions are totally exclusive of each other.

A fisheye is a specialist lens, and not one that you would recommend to your "average joe" taking on holidays, as their wide angle option.

By the way - don't try to pretend that the wikipedia definition may have been wrong, or contrary to other more reliable texts.
In this case the wikipedia definition is 100% correct, and you are 100% wrong.

I don't think you had useless teachers, as I do not think they would make this mistake.
I think it more likely that you just misunderstood what they were saying.

The two older versions do not have the focus motor your D5200 needs so they will not AF on a D5200. They also do not have VR.

Yes unfortunately the 70-300 is non VR I was ripped good on the bundle I bought. What is the new 18-55 VR 2 worth that came with the camera I want to sell it on eBay .?

Sharp Loc: Jax fla

Ok so 70-270 is a cleaner image thanks for that I keep getting hung up on wanting to zoom and forget about that issues of light and f stop being a greenhorn
Thanks to you all for your comments I appreciate it and it's fun to watch you guys chew on ea other a bit

Sharp Loc: Jax fla

Can you tell me this, can you notice any difference on the sigma or tamron lenses over the nikor lenses, I have seen a few people who say sigma is best of the three. So if I go say 18-300 or 70-300 and I will get the 10-20 for wide view outdoors prolly just keep the 18-55 nikor
