The 18-300mm f/3.5–6.3G lens (not to be confused with the 18-300mm f/3.5–5.6Glens) is a telephotosuperzoomlens manufactured by Nikon for its line of DXDSLRcameras.
As with other DX format lenses, the smaller image circle makes it compatible only with APS-C-sized image sensors. If used on a 35mm film SLR, vignetting will occur;[3] however, the lens can be used on an FX DSLR because the camera can be automatically or manually set "DX Crop Mode", eliminating vignette, but also reducing the image area from an FX-size sensor to a DX-size sensor[4]
The lens is designed to be an all-in-one solution.[5] This lens does not replace the 18-300mm f/3.5–5.6G.[6]
The differences between the lens and the 18-300mm f/3.5–5.6G are as follows:
Since it has the same focal length as the f/3.5–5.6G, it shares the record of having the largest zoom range of any other lens (interchangeable camera lenses only) currently manufactured.[10]
^"In the Nikon system, both crop sensor DX lenses and full frame FX lenses will function on crop or full frame bodies; HOWEVER (and it’s a big however), if you put a DX lens on a full frame body, you’ll see that a significant portion of the edge of the frame is black. This is caused by the smaller DX lens not reflecting the image onto the full area of the full frame sensor"."The Difference Between Full-Frame and Crop Sensor DSLR Cameras". Improvephotography.com.

^"Essentially, DX Crop Mode avoids the heavy vignetting that we would otherwise experience when using a DX lens on an FX camera by only recording the image using a smaller section in the center of the sensor. Of course, this results in an image with a reduced resolution"."What is the Difference Between Nikon DX and FX Lenses?". Photographybay.com. Retrieved 2016-07-08.
