Technical Discussions
Why Sensor Size Matters Part 1 of this series discussed what the different sensor sizes actually are and encouraged you to think in terms of the surface area of the sensors. It assured you the size of the sensor was important, but really didn’t explain how it was important (other than the crop-factor effect). This […]

We get a lot of questions about sensor sizes and crop factors. Most people know the difference between a standard (APS-C) crop sensor and a full-frame sensor. Not many, though, know how much smaller a 2/3” sensor is than a 4/3 sensor, and fewer still the difference between those and a 1/1.8” sensor. Plus Canon […]

What Is This? We started doing this several years ago. We have a unique opportunity: we own a very large number of lenses subjected to rather harsh conditions: they get packed in boxes, tossed around by UPS, and sometimes the user isn’t as careful with them as you would be with your own lenses. Our numbers […]
