What does 'cropping to 1x pixel resolution' mean?
Feb 14, 2014

Have an APS-C Pentax K-30, am learning sports photography, got the following advice from a friend, but I don't understand what he meant --

"Use as long focus distance as you can. The more you crop, the less sharp is the result. Do not ever consider cropping to the 1x pixel resolution! Sensors with Bayer pattern color filters never reproduce true per pixel details. Currently only Foveon sensors do. But with all conventional sensors you have about 1/2 of the color resolution, and low-pass filter softens image overall. So, for a conventional camera, consider true, per pixel details resolution to be about 1.5 to 2 times (linear) lower than the picture you get from the camera. Don't crop beyond that."

What does '1x pixel resolution' mean? Or his last sentence, that 1.5 to 2 times stuff? Help!
