If you shop for your digital SLR camera, then there is a factor, you might want to know who the "crop factor". The reason for this feature is important because this can give a different optical performance you expect. When it comes to compact cameras, you see that you get, and if the compact camera with 35 mm equivalent lens, so you would have the same power of a lens of 35 mm. However, it isis not necessarily true in the case of digital SLR cameras.
The sensors of most digital SLR cameras is smaller than 35 mm film and a camera with 1.5, 1.6 or 2.0 crop factor is a small area and collection to capture the eye. If you have a focal length of 100 mm and the length of a camera has a crop factor of 1.5, then the final set of 150mm focal length would be. The photographers, who probably do more indoor photos or landscapes are those that are normally affected by the factor of culture orat least consider the purchase of lenses for their digital SLRs. However, if you take pictures and more wild animals, portrait, macro or not, you might worry about this problem at all. One way it works, but it is a camera that has a crop factor of zero or the purchase of a full frame digital SLR. These cameras are generally more expensive and, if necessary, the purchase could not be justified at all.
Another fact that is good to know that every camera manufacturercrop factor cameras for their constant and therefore the number does not vary from one camera model to another within the same brand. The terms of conversion factor on the focal length and focal length will often be used instead of "crop factor" figures and the most common 1.5, nikon and Sony, 1.6x, 2.0xe used by canon, Olympus used to be.
