Those sensor and lens size combinations are designed to produce fields of view that are similar to the 35mm film camera field of view. So, today's digital cameras are equipped with various image sensor, lens size/focal length combinations. That is why you will see the phrase 35mm equivalent used.ģ5mm Equivalent Focal Lengths: You can see that using the smaller image sensors with a 35mm camera and its lens may not provide an acceptable field of view. (cropped)įor the record, the field of view from a 35mm film camera and its lens is the standard field of view to which digital camera fields of view are compared. With each smaller sized image sensor, more of the outer areas of the scene are lost. The light capturing area (imaging area) of most digital camera image sensors is smaller than the imaging area of film.Īs you can see from the example above, the widest field of view is produced when 35mm film or a full frame image sensor is used. Why are there different Fields of View?: Today's digital cameras use image sensors to capture the light that comes through the camera lens whereas 35mm cameras used film to capture the light. A wide variety of sizes, and types of Digital Photo Frames are available at (actual measurements 6.16mm X 4.62mm) This is the sensor size which is found in most Basic Compact Digital Cameras.Īre your favorite family and vacation pictures just sitting in your computer or cell phone? Put them all on display with a Digital Photo Frame. White Rectangle: This field of view is what you would get from using a 1/ 2.3 size image sensor in a 35mm camera. This size image sensor can be found on cameras like the Panasonic Lumix DMC-ZS100. Pink Rectangle: This is the field of view that would be seen if an image sensor that measures 13.2mm X 8.8mm (also known as a 1" sensor) were used with a 35mm camera. This size image sensor can be found in many Compact System Cameras Yellow Rectangle: This area represents the field of view you would see if a Micro 4/3 image sensor which measures 17.3mm X 13.0mm were used with a 35mm camera. (the Canon APS-C image sensors are slightly smaller, 22.3mm X 14.9mm) Some Compact System Cameras like the Sony a6100 are equipped with APS-C image sensors. It is commonly known as an APS-C size image sensor. This size image sensor is found in most non professional Digital Slr cameras like the Nikon D3500. ![]() Full frame image sensors are found on higher end Digital Slr cameras.īlue Rectangle: The area inside the blue rectangle represents the field of view that would be seen if an image sensor that measures 23.6mm X 15.7mm were used. (measuring 36mm X 24mm) Therefore, with all other things being equal, the field of view will be the same. Red Rectangle: The area inside the red rectangle represents the field of view that you would see through a 35mm film camera or a Digital Slr camera equipped with a full frame image sensor.Ī full frame image sensor's light capturing area is about the same as that of 35mm film. (That is, as long as the same lens and focal length is being used for each camera) The image also shows the different fields of view you will see from digital cameras that use various size image sensors to capture light from a scene rather than film. (for the sake of this example, just assume that the 35mm camera was equipped with a 50mm focal length lens.) The full image area below shows the field of view you would see if the picture were taken with a 35mm camera that uses 35mm film. So, going forward, remember that the term 35mm equivalent focal length is a reference to the field of view or angle of view of a digital camera lens compared to that of a "35mm camera".Ĭomparison of Fields of View. Different types of digital cameras have various sized image sensors and the size of the image sensor will have an impact on the field of view seen through the camera lens. (the light capturing area of the film)ĭigital cameras use image sensors rather than film to capture the light that will produce a digital picture. The diagram of the film strip above shows the dimensions of the 35mm film including the 24mm X 36mm imaging area.
