Is this the right conclusion? (DX 35mm lens)

Yes. Yes. Yes.
For a Nikon DX camera, the conversion factor is 1.5. So it's 35mm X 1.5 = 52.5mm equivalent focal length to a full frame sensor.

Yes a 35mm lens will give you with a cropped sensor near the same coverage of a 50mm lens with a film camera.

You are correct, however it does not have to be a DX lens. Any 35 mm lens, DX or FX, Nikon or third-party brand, when mounted on your camera will produce the same field of view. The focal length of a 35 millimeter lens is identical regardless of whether the lens is designed for a crop or full frame camera.
DX lenses are designed specifically for crop frame cameras and produce a smaller image circle to cover the size of those sensors. FX lenses have a larger image circle to cover the sensor of a full frame camera. When FX lenses are used on a DX camera the outer portion of the image circle that they can produce is not used. However the FX lens still produces the identical field of view on a DX body as a DX lens will.

Technically, a DX crop frame is 1.6 times smaller than FX. So, if you want to get *exactly* 50mm of a 35mm camera, you'd have to have a lens of 31.3mm on a DX body (31.3 x 1.6 = 50.08). Since they don't make that size, you'll have to add in a "fudge factor."

So you use a Canon which is 1.6 Nikon is 1.5

Here's a link to a good illustration and explanation about Crop Factor (Sensor Size) Please note that Nikon's Crop is missing it is 1.5x

So I use my 35f1.8 DX lens on my D600 set to full frame and get artsy fall off on the image edges. Works for me!

While the 35mm will give you the approximate focal length, one thing to note is that the 35mm film had a ratio of 3x4, the dslr ratio is 2x3. Please correct me hogs if I'm wrong. So things will look a bit different.

True, but that's a completely different discussion.

I started out in 35mm in 1973; I bought a whole gamut of lenses (eventually going with zoom (wide angle and telephoto). I jumped into digitial photography about 8 years ago; everyone wrote about crop factor and trying to figure out how "long" the lens really was. When I took my Nikon D40 out and shot at 18mm, it was wide angled! At that point I stopped being bothered about "crop factor" and just enjoyed photography. When I shoot my 28-75 zoom at 28mm, I think of it as 28mm; if I want it wider, I go to my ~gasp~ kit lens and shoot upwards from 18mm. Stop bothering yourself with all of the "crap factor" stuff and just enjoy photography; use the gear you have to take the best photos possible.

Thanks. I was thinking about the standard print sizes 5x7, 8x10, 11x14 versus the actual image aspect ratio.

35mm film was used for movies before they were used for still. The normal frame for 35mm movies is 4:3 aspect ratio. It's about half the frame of 35mm still.
