When shopping for your DSLR camera apart from just looking at the price, it’s also important to look into sensor sizes and crop factor because these too has a way of influencing your photography. Knowing the size of the sensor in your camera and how it affects the zoom capabilities together with crop factor is vital in helping you make an informed investment.
The camera sensor size is very important because it is what basically determines the amount of light that a camera uses to create an image. Image sensors consist of millions of light sensitive spots called photo sites, which are used to record information about what is seen through the lens. This qualifies the reason that a bigger sensor can gain more information than a smaller one thus capable of producing better image. Large DSLR photo sites are capable of turning out photos with better dynamic range with less noise and improved low light performance than those with smaller DSLR sensor.
Large sensors are well known to help in capturing better quality images this makes it a major preference for pro photographers unlike the smaller sensors. Though the larger camera sensors requires bigger lens on which it can be cast that makes the entire package look much bigger, the benefit of quality photos that come with it cannot be compared to any.
Bigger sensors also work well by isolating images in focus while having other images blurred. The smaller camera sensors struggle with this as they need to be moved further from the subject or use a wider angle to take the same photo otherwise with the help of crop factor you can still have the same better results. Professional cameras have a sensor the same size as a 35mm piece of film. When you put lens meant for a full frame camera onto a body with a crop sensor it produces crop factor.
With the help of crop factor you can increase the size the image by cropping the image then maximizing it with the help of crop factor. Given many camera sensors are smaller than the film making the image taken by the cameras to appear smaller, with the help of a crop factor the same image can be enlarged. Crop factor is therefore the difference between your camera’s size and the 35mm film frame. It’s normally used as a way of comparing lens focal lengths when fitted to different cameras. If a camera has a crop factor of 2 that means a 35mm is twice as large as your camera’s sensor.
DSLR cameras have sensors that are the same size as 35mm films making them have a crop factor of 1 also known as full frame. The higher the cropping factor the more noticeable the zooming in effect for a given focal length. Understanding these helps in making the right choice when choosing between different lenses and cameras and removes any guess work when it comes to choosing lens. A factor that is very important in case of professional photography.
