Crop factor and focal length multiplier. When we say “crop factor” we refer to the sensor’s diagonal size compared to a full-frame 35 mm sensor. It is called this because when using a 35 mm lens, such a sensor effectively crops out this much of the image at its exterior (due to its limited size). With crop sensors we can find both advantages and disadvantages. The greatest benefit is when we want to approach as much as we can to main subject. A standard 100 mm lens on a 1.6x crop factor it become 160 mm lens! Another good part is that the sensors use more of the lens center, which is sharpest, while quality degrades progressively toward to the edges. This is one reason that involves to buy sharpest lens as you can afford on a full frame format camera. On the other hand, a full frame sensor can provide a much better dynamic range and better low light with high ISO performance. Another think that you must consider is that a full frame DSLR will have a shallower depth of field because larger the sensor is, the longer the focal length required to create the same field of view, hence a shallower depth of field is created due to the additional focal length which can be a good think especially in food photography. In conclusion, we can say that a full frame sensor DSLR and a crop sensor DSLR have their own advantages and disadvantages. While a full frame DSLR provides a bit better overall quality, a crop sensor is much cheaper.
