Perspective? (Field of View)

[Buddha]

Normally I think I understand what a 1.6 crop does to effect what you see in the viewfinder, but every once in a while something I read says Nope, not yet you don't.
So, with a 50mm lens, a 1.6 crop camera gives me the same field of view as a full frame 80mm lens. Is that accurate?
That same 50mm lens also gives me a 1.0 magnification, not the 1.6 magnification that an 80mm lens would. Is that accurate?

Thanks

There are others on here that can explain it better than I but the 1.6 crop factor affects your angle of view. So a 50mm lens on a DX sensor would have about the same angle of view as an 80mm on an FX sensor.


**EDIT**
From the Nikon USA site regarding the 50mm f1.8D lense
Maximum Angle of View (DX-format) 31°30'
Maximum Angle of View (FX-format) 46°

leave the word magnification out. it doesn't magnify anything.
a lens will project a circular image on any surface. That circle of course is a specific size at a specific distance.
So you have the same lens on two camera's, the size of the image projected is the same on both camera sensors, but it just so happens that one of the camera's sensors is physically smaller than the other one, so it really doesn't change the size of the image, it only changes where it is cropping, or what most people are calling the field of view.

Okay. I'm good. I understood it correctly, and an article I just read about a lens was incorrect.
Thanks
