Camera knowledge base
Understand the specs before you buy
No simplistic camera rankings. We explain specifications and use cases first, then help you narrow the field.
Articles, tools, and methods
What should you look for in a camera?
Start with your use case, then check the sensor, lenses, autofocus, video, and total budget in order.
Read guideFull frame vs APS-C: which to choose
Understand the tradeoffs in area, pixel density, size, and lens cost.
Read guideCamera sensor size comparison
Compare 1-inch, APS-C, full-frame, and medium-format sensors at true proportions.
Read guideHow pixel pitch and crop factor are calculated
See the formulas, assumptions, and error bounds behind our derived data.
Read guideWhy one camera can have several names
Understand model aliases used by Canon, Panasonic, and others across markets.
Read guideStart with the sensor
Area affects light-gathering potential as well as the size of the body and lens system.
Then check derived metrics
Pixel pitch and density need the context of release date and sensor architecture.
Finally verify the model
Regional aliases differ, so confirm that names refer to the same camera before buying.
