Large Viewfinder: Effective size over 0.7 with less than 100% coverage. Large 100% Coverage Viewfinder: Effective size between 0.6 and 0.7 and 100% coverage. Large Viewfinder: Effective size between 0.6 and 0.7 with less than 100% coverage. Theres also a range of more minor differences (which vary depending on the camera. Medium Viewfinder: Effective size between 0.5 and 0.6 with less than 100% coverage. Interchangeable Lenses Camera Sensor Size. Small Viewfinder: Effective size below 0.5 with less than 100% coverage. Large 100% Coverage Viewfinder: Effective size over 0.7 and 100% coverage. Medium 100% Coverage Viewfinder: Effective size between 0.5 and 0.6 and 100% coverage. The effective size should be used when comparing viewfinders of cameras with different crop factors.Ĭlick on column headings to sort the table. For reference, the crop factor and resolution of each camera is also shown. Since a 50mm lens gives a different field-of-view depending on the crop-factor, the measured magnification differs too. The viewfinder must be held up to the photographers eye to be seen, as it is built into the camera itself, as opposed to a LCD display or focusing screen that. Magnification is relative because manufacturers all use the field-of-view obtained by a 50mm lens as their basis. For cameras with the same crop-factor (focal-length-multiplier), magnification can be used to compare viewfinder size. Magnification is a relative measure which compares the size of what we see through the viewfinder to what we would be seeing without looking through a viewfnder. Therefore, a viewfinder with a coverage of 100%, shows the entire image to be captured. Coverage is measured as a percentage of the full image captured. The table below shows the specification of each DSLR camera's viewfinder. The viewfinder is one of the most important parts of a camera that a photographer uses to compose the picture, and adjust. So, once image quality is good enough, why not select a camera based on its viewfinder? The more you use your digital SLR, the more you will notice the viewfinder - and its limitations. With modern DSLR cameras, viewfinder size varies more than image quality. The greater a viewfinder's coverage, the easier it is to precisely compose photographs. The larger the viewfinder, the easier it is to judge focus and to see subject detail. The size of a camera's viewfinder can greatly affect its usability.
