Is there any such thing called FX to DX converter from Nikon?
I was wondering if there's any such thing called FX to DX Converter because I really fell in love with this lens from Nikon - AF-S NIKKOR 50mm f/1.8G (Special Edition) and I really want to buy it. But the problem is that this lens is basically based on FX cameras and I have the D3200 which is DX so, there comes a crop factor.
A 50mm lens on your D3200 will have the equivalent angle of view of a 75mm lens on a full-frame (FX) DSLR. This makes the 50mm on your D3200 a good choice for portraits.
On a 35mm film camera or full-frame DSLR a 50mm lens is considered a "normal" lens since on those cameras its angle of view approximates that of the human eye.
On your D3200 with its crop sensor a 35mm lens will have the equivalent angle of view of a 52.5mm lens on a full-frame DSLR so on your D3200 it is considered a "normal" lens.
So if you want to shoot portraits use the 50mm lens. If you want to capture scenes closer to how you saw them with your eyes use the 35mm lens.
If you want the equivalent to 50mm for use on DX you should buy a 35mm lens. I doubt that such a converter as you want exists, but if it did it would have to be very expensive to have any hope of giving a good quality image, and even then would not be as good as a prime lens of shorter focal length - at much greater combined cost!
Be sensible, decide which focal length suits you (use your kit lens at various settings to help you decide), then buy the prime lens that suits you.
No other course of action is at all sensible.
The 50mm f/1.8 AF-S G will work flawlessly with your D3200. Yes, everything including autofocus will work because of the AF-S spec. The FX tag only means it can be used with both film, full-frame and digital cameras.
No need for converter. There's no such thing (converter for FX to DX). Crop factor is about what you see (when the lens is on an FX camera as opposed to when it is on a DX camera). Nothing changes on the lens except angle of view. The lens is narrower on a DX by 1.5X so a 50mm lens in FX will act like a 75mm in FX when placed in a DX camera. When placed on a DX camera, the 50mm lens is still called a 50mm. To get the same angle of view of a 50mm lens on a FX camera, get a 35mm for your DX camera. I believe Nikon has a 35mm f/1.8 AF-S (DX). Make sure you get AF-S to preserve autofocus with your camera. AF only is not enough.
