This shallower depth of field is especially noticeable at apertures of f/2.8 and wider, and makes it easier to achieve pleasing pictorial results in portraits or scenes where the sharply rendered main subject “pops” off the soft background or foreground. As a result, full-frame lenses of equivalent coverage provide a shallower depth-of-field at any given aperture, so long as the images being compared have the same field of view (framing). For example, 50mm, 35mm, and 25mm lenses are normal lenses on full-frame-, APS-C-, and Micro Four Thirds-format cameras respectively. Full-frame cameras provide enhanced depth-of-field controlįull-frame cameras require longer focal-length lenses to cover the larger 24 x36mm format at any given coverage angle, compared to smaller-sensor cameras. Meanwhile, the broad-spectrum Sony Alpha a7R IV, has an ultra-high-res, full-frame 62.5MP CMOS sensor and a top ISO of “only” 102400. The manufacturer determines the precise balance between high ISO performance and high resolution largely based on the needs of end users.Ī classic example: The Sony Alpha a7S III, which has a full-frame 12.1MP CMOS sensor, and a top ISO of 409600, is aimed primarily at low-light shooters and videographers. But these pixels are still large enough to retain the large sensor advantages of high image quality, extended dynamic range, etc. Increasing the number of pixels on a full-frame sensor does make each individual pixel smaller. This enhances the sensor’s ability to capture fine detail. Full-frame cameras can deliver higher resolutionįull-frame sensors can also be configured to provide higher MP ratings and greater resolution than smaller sensors. All these characteristics enhance the accuracy, realism and vibrancy of the captured image. They can also capture a greater dynamic range, and differentiate finer color variations within a given hue. This is the main reason full-frame sensors can deliver better performance at higher ISO settings than so-called crop sensors. Larger pixels can capture more color information and also capture incoming light with greater efficiency and less noise than smaller pixels. Think of a pixel as a two-dimensional image element or image capture point. The larger the sensor, the larger each pixel will be for a sensor of any given megapixel (MP) rating. Full-frame cameras have bigger, better pixels Pixel Power: The Benefits of a Full-Frame Digital Camera 1. While there are higher quality sensor types out there, like medium format cameras, many professionals prefer the full-frame format. Typically, mid to professional-level mirrorless or DSLR cameras are full frame cameras.Ī full frame sensor allows for more light and information to get into the camera, which increases quality and sharpness and provides greater dynamic range. Full frame cameras provide the largest sensor you can buy in a consumer camera. What is a full frame camera?Ī full frame camera is a digital camera that has a sensor that is equal to the size of 35mm film, or 36x24mm. Here’s how each one affects image quality. To understand exactly how this works, you’ve got to wrap your head around two basic ideas: pixel size and pixel density, that is, the number of pixels per square millimeter. Why do so many top pros and discriminating shooters choose cameras with 24x36mm sensors? Because a full frame camera gives them benefits and an edge, both in terms of image quality and creative control.
