Because sensors are generally smaller than a full frame image on 35 mm film, the frame gets filled up sooner. Bad explanation... Here's a great explanation, if you are a visual learner.

Your question isn't completely sparkling, yet then the issue of crop aspects is something that the digital camera manufacturers have made much greater complicated than mandatory. The focal length of a lens is what it somewhat is. So in case you have an 18-55mm lens, this is the focal length regardless of what digital camera it somewhat is used with. The focal length is a measurable measurement and not concern to producer's score video games. Crop factor is a thought that comes approximately while the producer of the digital camera makes use of a sensor this is bodily smaller than the wide-unfold 35mm action picture physique. once you're using action picture, the lens projects a picture on the action picture physique this is predicated on the layout of the digital camera and lens mixture. contained in relation to 35mm, that image is a circle this is approximately 40 4-45mm in diameter. Now, in case you opt for to apply in basic terms somewhat of that image, you have 'cropped' the image. you additionally can use lens with an prolonged focal length which will project a 40 4-45mm circle yet that includes precisely a similar image. as a result, using an prolonged focal length image can sensible lead bypass cropping of the image. what's complete with digital cameras is to apply a sensor this is bodily smaller than the 24x36mm dimensions of the wide-unfold 35mm action picture physique, yet then couple that with use of a SHORTER focal length lens so as which you seize a similar image on that smaller sensor which you may seize on action picture using an prolonged lens. this is, the 18 - 55mm lens this is provided with Nikon DX digital cameras such with the aid of fact the D5100 or the D100 will create a similar image on the sensor in those digital cameras as a 27 - eighty two.5mm lens on a 35mm action picture digital camera.

Yes, this is due to the fact that a digital sensor is smaller than 35mm film, thus the conversion factor.
