What is a Full Frame Camera?

​

A full frame camera refers to a digital camera with a sensor that is the same size as a traditional 35mm film negative, measuring 36x24mm. This is larger than the sensors found in most DSLRs, which typically measure around 24x16mm. Cameras with these smaller sensors are classified as APS-C, a term derived from the Advanced Photo System type-C film format, which shares similar dimensions.

​

When digital photography was in its infancy, nearly all digital cameras had sensors approximately the size of APS-C sensors. These smaller sensors produce images with a narrower angle of view compared to full frame sensors because they capture a smaller portion of the image. This phenomenon is often referred to as the crop factor.

​

Understanding Crop Factor

​

The crop factor is a critical concept in digital photography. It refers to the ratio of the sensor size compared to a full frame sensor. For APS-C sensors, this factor is typically around 1.6x. This means that a lens will produce a tighter, more zoomed-in image on an APS-C sensor compared to a full frame sensor.

​

For instance, a 35mm lens on a full frame camera captures images as a true 35mm lens would on a 35mm film camera. However, the same 35mm lens on an APS-C camera behaves differently due to the crop factor. On a camera with a 1.6x crop factor, the 35mm lens effectively acts like a 56mm lens (35mm x 1.6 = 56mm), resulting in a less wide-angle field of view.

​

Full Frame vs. APS-C

​

The choice between full frame and APS-C cameras depends on various factors, including the type of photography one engages in and personal preferences regarding image quality and field of view. Here are some key differences:

​

1. Field of View: Full frame cameras provide a wider field of view compared to APS-C cameras. This makes them ideal for landscape and architectural photography where capturing wide scenes is essential.

2. Image Quality: Full frame sensors generally offer better image quality, especially in low light conditions. They can gather more light due to their larger size, resulting in better noise performance and higher dynamic range.

3. Depth of Field: Full frame cameras can achieve a shallower depth of field than APS-C cameras at the same aperture, which is beneficial for portrait photography to achieve a pleasing background blur.

4. Lens Compatibility: Full frame cameras utilize lenses designed for 35mm film cameras, maintaining their intended focal length characteristics. Conversely, lenses on APS-C cameras must account for the crop factor, affecting their effective focal length.

​​

​

Practical Implications

​

Understanding the crop factor is crucial when selecting lenses for your camera. For example, a 20mm lens on an APS-C camera with a 1.6x crop factor does not behave as an ultra-wide lens. Instead, it functions more like a 32mm lens (20mm x 1.6 = 32mm), losing much of its wide-angle capability.

​

In contrast, using a 35mm lens on a full frame camera preserves the lens's original perspective, ensuring that it remains a 35mm lens in terms of field of view and image characteristics. This zero crop factor of full frame cameras means photographers can utilize their lenses' full potential without modification.

​

In conclusion, while APS-C cameras are popular and versatile, full frame cameras are often preferred by professionals and enthusiasts who seek the highest image quality and the most accurate representation of their lenses' focal lengths. Understanding these differences helps photographers make informed decisions about their equipment based on their specific needs and artistic goals.

Understanding Crop Factor: A Simple Illustration

​

Confused? Let’s break it down with a practical example.

​

Imagine you're standing on the beach, photographing a distant lighthouse. You start with a film camera using a standard roll of 35mm film. The entire lighthouse fills the frame of your image perfectly. Now, without moving from your spot, you switch to your digital SLR camera.

Here’s the catch: your digital camera's sensor is smaller than that of the 35mm film. You take a picture with the digital camera and then compare it to the film photograph. Notice anything different? Large sections around the top and sides of your image are missing, creating an effect that almost seems like the image is zoomed in.

​

This phenomenon is due to the crop factor. Your APS-C digital SLR camera has a smaller sensor than the film camera, so it captures less of the scene. This results in what appears to be a cropped image, where only the central portion of the lighthouse is visible, as opposed to the entire structure seen in the film photograph.

​

To visualize it better, think of the digital camera's sensor as a smaller window looking at the same scene. To include the areas that were cropped out, you would need to step backward, widening your view until the lighthouse fits within the frame just like it did with the 35mm film camera.

Understanding this crop factor is crucial for photographers, especially when switching between film and digital formats or different types of digital cameras. It helps in anticipating how much of a scene will be captured and making necessary adjustments to achieve the desired composition.

What is Crop Factor?

​

Crop factor is a term used to describe the difference in field of view between a digital camera with a smaller sensor (like APS-C) and a camera with a full-frame sensor (equivalent to a 35mm film frame). The crop factor is the ratio of the full-frame sensor size to the smaller sensor size. It affects how lenses perform in terms of their effective focal length on different cameras.

​

Practical Example

​

Imagine you're using two cameras: one with a full-frame sensor and another with an APS-C sensor, both equipped with a 50mm lens.

​

1. Full-Frame Camera:

   • You take a photo with the 50mm lens.

   • The field of view is wide, capturing a large portion of the scene, just as a 50mm lens would traditionally.

2. APS-C Camera:

   • You use the same 50mm lens, but due to the crop factor (usually 1.5x or 1.6x), the image appears more zoomed in.

   • The effective focal length becomes 75mm or 80mm (50mm x 1.5 or 1.6).

   • The field of view is narrower, similar to what you’d see with a 75mm or 80mm lens on a full-frame camera.

 

Day-to-Day Photography Scenarios

​

1. Portrait Photography:

   • Full-Frame: Using an 85mm lens gives a natural perspective with a flattering background blur.

   • APS-C: The same 85mm lens effectively becomes about 127mm (85mm x 1.5), giving a tighter shot, which might be better for headshots but too close for full-body portraits.

2. Landscape Photography:

   • Full-Frame: A 24mm wide-angle lens captures a broad, expansive view of the landscape.

   • APS-C: The 24mm lens effectively becomes 36mm (24mm x 1.5), which reduces the wide-angle effect and captures less of the scene, requiring you to step back to fit more in.

3. Sports Photography:

   • Full-Frame: A 200mm lens captures players from a distance with good reach.

   • APS-C: The 200mm lens effectively becomes 300mm (200mm x 1.5), giving you more zoom to capture distant action more closely without changing your position.​

 

Visualizing the Crop Factor

​

To visualize the crop factor, think of taking a photo through a window:

​

• Full-Frame: The window is large, allowing you to see a wide scene.

• APS-C: The window is smaller, so you see a smaller, zoomed-in portion of the same scene.​

 

Understanding crop the factor, helps photographers choose the right equipment and position themselves appropriately to achieve their desired compositions, regardless of the sensor size of their camera.

Type                   Dimensions              Description

 

Compact              8.8 x 6.6mm                This is the type of sensor that's used in many compact digital cameras.

Micro 4/3rds        17.3 x 13mm               This sensor is used in mirrorless digital SLRs made by Panasonic and Olympus.

4/3rds                  18 x 13.5mm               All Olympus digital SLR cameras include this size sensor.

APS-C                 23.7 x 15.7mm            This is the most common sensor size in digital SLR cameras and is used in some mirrorless DSLRs.                 Full Frame           36 x 24mm                   Used in high-end digital SLRs, this sensor is the same size as a frame of 35mm film.                          

 

 

The comparison above gives an accurate indication on the relative sizes of different sensors. In order to compact the amount of photosites (Individual light sensitive element in a digital image sensor / One colour pixel in a CCD or CMOS sensor) onto the APS-C digital SLR camera sensor. Each photosite must be smaller in order to fit into the reduced surface area of the camera.

 

When the photosite surface area decreases it is less effective at capturing extended dynamic range (Highlights, midtones, Shadows) and it produces more noise at a higher ISO setting. So to compensate for this. The manufacturers pack the sensor with more megapixels thus reducing the size of each photosite. Which results in two benefits for the consumer. The first one being when you print out your images at a larger size, you won't lose any data detail. Secondly, you can crop out huge sections of the image and still print it at a very large size.
