I have a D5200 and I'm wanting to purchase my first lens but I don't know which way to go because from what I've gathered by the 1.5 crop sensor if I buy the 35mm lens (which is the focal length I want) I would achieve 52.5mm? Being that 35x1.5 is 52.5...I'm really confused on just this. I've seen that Nikon makes a 24mm lens for their 1 Series but from there I'm just lost. I like the 35mm focal length that I've always used on film slr's, been great for portraits and scenery as everyone knows. Please help haha, I'm heading for to see my girlfriend in England soon and would love to have a new lens too.
I need "true" 35mm's if that makes sense.
Thanks!
No one said yes, so I will.
Yes, a 35mm on a DX D5200 camera, or a 50 mm lens on a FX or 35mm film camera, would see the same field of view, if standing at the same place.
Saying again, if you want to see the view that 50mm shows on a 35mm film camera, then a 35mm lens will show that same view on a DX body.
The 35mm lens is always a 35 mm lens, it does not change in any way on a DX camera. But its field of view (being cropped smaller by the smaller DX sensor) sees the same view that 50 mm would see on the larger FX or 35mm film camera (if standing in the same place).
This 35mm lens with similarity of view is called a 50mm equivalent focal length (1.5x longer), meaning, we see what a 50mm on a FX body would see - merely so you can compare it to the view of 35mm film cameras. Said "equivalent focal length" merely because the field of views are the same (but it is always still a 35mm lens). What we see appears like a telephoto effect, but DX is only cropped smaller, and then we enlarge it a bit more, to compare at same size. Any cropped photo does that too.
The 35 mm lens is a shorter lens, so the DX camera would have slightly more depth of field with it than a 50mm lens on the larger FX sensor would. But the field of view is the same.
