Frequently Asked Questions
Which camera sensor size is best?
There is no universally best sensor — it depends on your use case. Full Frame (36×24mm) offers the best low-light performance and shallowest depth of field, ideal for portraits and low-light work. APS-C offers a good balance of size, cost, and quality for most photography. Micro Four Thirds is excellent for travel due to compact lens sizes. Larger sensors are not always better if you need portability.
What is crop factor and why does it matter?
Crop factor (or focal length multiplier) describes how a sensor's size relates to full frame (36×24mm). APS-C has a crop factor of ~1.5–1.6× — a 50mm lens behaves like a 75–80mm lens. Micro Four Thirds has a 2× crop factor. Larger crop factors effectively multiply the focal length, giving more reach (good for wildlife) but less wide-angle coverage.
Is APS-C bigger than Micro Four Thirds?
Yes. APS-C sensors measure approximately 23.5×15.6mm (area: ~367 mm²). Micro Four Thirds sensors measure 17.3×13mm (area: ~225 mm²). APS-C is about 63% larger in surface area than MFT, which generally means better light gathering ability and slightly more background blur.
Does a bigger sensor mean better image quality?
Larger sensors generally offer better low-light performance, greater dynamic range, and shallower depth of field control. However, lens quality, camera processing, and photographer skill often matter more than raw sensor size. A skilled photographer with a small-sensor camera will consistently outperform a poor photographer with a full-frame camera.
What sensor size do phone cameras use?
Most smartphones use sensors in the 1/1.28" to 1/2.5" range (roughly 9×7mm to 5.6×4.2mm). High-end flagship phones like the iPhone 16 Pro and Samsung S24 Ultra push toward 1/1.3" sensors, which are still much smaller than any dedicated camera format.
How does sensor size affect depth of field?
Larger sensors produce shallower depth of field (more background blur) at the same aperture and equivalent field of view. To get the same depth of field as full frame at f/2, an APS-C shooter needs f/1.4 and a MFT shooter needs f/1. This is why full frame is preferred for portrait photography with creamy bokeh.
