Sorry guys but gotta ask. Which is the largest sensor, 1/1.8 or 1/2.5. Sorry but just can't do the math (whatever it is).

Thanks,

1/1.8 larger number on bottom means smaller number

Aswsandman1 says, a larger number on the bottom of a fraction (denominator) means a smaller value. 1/2 is larger that 1/3, which is larger than 1/4, etc.

You can't blame anyone for getting confused - whoever heard of mixing fractions and decimals in the same figure - it is a bit weird!! But nevertheless - best think of it as a fraction (with a decimal as part of it!!! :roll

I have a confession; I was confused when I was trying to choose between the Canon G7 and the S5 IS. One has a 1/1.8 sensor and the other has a 1/1.25. I had to use a calculator to determine which one was the larger sensor. So that means that the 1/1.8= .5555 is smaller than the 1/1.25 - .8 Sorry for the confusion and thanks for being polite about my mistake. Bill

I find it helpful to wear my glasses when reading the specs for the cameras. The G7 CCD sensor is 1/1.8 (0.556") as you stated. However, the S5 CCD is actually 1/2.5 = 0.40", and therefore smaller.
