Frist let’s talk about some camera specifications. The two main types of DSLR camera format are (DX) and (FX).
When a new photographer decides to get serious about photography and their photography knowledge out grows the limitations of a point-and-shoot camera, it’s time to invest in a more advanced versatile camera which is the DSLR camera, short for (Single Lens Reflex).
The DX-format has a cropped sensor which means some of the image area will be cut off or cropped. The DX sensor covers a smaller portion of the image projected by the lens, a 1.5x crop factor. The smaller sensor crops the image more. For example, a 24mm lens on a DX sensor camera will provide an approximate 36mm view.
These lenses are smaller and lighter in weight and are more affordable. This is Nikon’s (Prosumer) line. They are high-performance lenses with a variety of focal lengths and zoom options. What you see through the viewfinder will be cropped in the final printed image.
The DX cameras are the most popular among new photographers because they are less expensive. The DX format has an added benefit of being able to use both DX and non-DX NIKKOR lenses. The non-DX lens image circle is larger than needed on a DX-format camera.
To figure out the focal length of a DX lens, look at the lens, read the focal length (ie. 50mm) and just multiply that number by 1.6 (50mm x 1.6= 80mm). The focal length for this lens is 80mm not 50mm.
The FX-format body has a full frame sensor. The larger FX-format sensor measures 36x24mm which is approximately the same size as 35mm film. The FX body is a part of Nikon’s (Pro) line.
What you see through the view finder is what you will get in the final image. The FX sensor, has more “light gathering” area and offers higher sensitivity and generally, lower noise. There is no crop factor present with the FX sensor. FX cameras can also use DX lenses. However, to avoid vignetting or darkened edges, the DX crop mode is automatically selected by the FX camera when a DX lens is attached.
To figure out the focal length of a FX lens, look at the lens, read the focal length (ie.50mm) that’s it. The focal length you see is the focal length you get. Nikon offers a variety of DX and FX lenses. A knowable photographer can work with both types of cameras, but when you want the best image possible go with the (FX) format.
1. A larger sensor, more “light gathering” area.
2. What you see in the view finder is what you get.
3. Better image quality and better clarity.
4. Larger megapixels.
5. The capability to use a higher ISO.
6. Your images will look better.
You make the choice!
