Sensor Size

There  are so many question that come up when it comes to sensor size and I could write on the subject for 10,000 words or more. It would be informative, overwhelming, and boring for the most part. Take a listen to this 20 minute episode on Sensor Sizes from FX and EF to DX and EF-S. Nikon and Canon DSLRs are the main subjects of my talk but at the very least you will be acquainted with the difference between larger and/or smaller sensors.

Larger Sensor

Smaller Sensor

Higher Resolution

Lower Resolution

Better Low Light Performance

Poorer Low Light Performance

Better Dynamic Range

Poorer Dynamic Range

Shallower Depth of Field

Longer Depth of Field

Less Diffraction

More Diffraction

Reduction in Crop Factor

Increased Crop Factor

Diffraction: When you use a small aperture, light reaching the edges of the image sensor can only get there after passing through the small aperture and then spreading out. That spreading of light causes the light rays to hit adjacent photo sites. Essentially, this spreading causes the light to sometimes hit the wrong photo site and leads to blur.

35mm film: It is the width of the film including the sprocket holes.

Happy Shooting!
