That 1.6 Rule

Hi guys,

I have always bought full frame cameras which have a ratio of 1-1

A friend of mine bought a new Canon 200Dmark 11 with an APSC Comos Sensor recently with a 18-55mm kit lens.

Please tell me dose the 1.6 rule still apply to these sensors or have they fixed this so that what you have on the barrel of the lens is actually the correct reading.

Otherwise 18mm becomes 28.8mm and 55 becomes 88mm

Thank you.

Leon
