Sunny 16 Rule says: On a sunny day our preliminary exposure settings are:
Aperture: F/16
ISO = ISO
Shutter speed= 1/ISO
Now if I have a camera with 1.5 crop factor, would this affect the sunny 16 Rule ?!
Logically i think it has no affect but by searching the internet i have found different opinions, what do you think ?

I don’t see how a different crop factor would change the rule.
There are, of course, other factors that would cause you to choose a different shutter speed
and aperture combination with any given ISO. That’s the fun part.

Agree with you Mandrake, i do not think the crop factor will affect the Sunny 16 Rule,

Okay… I’m not an expert on photography (as I’m sure you can tell by the next comment)… but wouldn’t a smaller sensor get less light? Therefore, the smaller the sensor, the more you would have to compensate with some other variable? Maybe I’m just confusing myself… See, I told you – no expert here

Michael… Your point is well taken and has me thinking. I do believe that a full frame DSLR does not need as high a ISO to achieve proper exposure as a Crop Sensor camera with other factors remaining equal. This would change the equation used in the Sunny 16 rule to determine exposure.
I’ve taken another look at Oksana’s Sunny 16 lesson (lesson #13) and she does not mention the sensor size as a factor. I believe that she was using a D7000 (crop sensor camera) in the tutorial.) I’ve not seen any discussion of the rule mentioning sensor size.
Oksana…. I think it’s time for your expertise. Does sensor size affect the Sunny 16 rule?

Honestly I never heard about sensor size influencing Sunny 16 Rule. It also doesn’t make too much sense to me. Exposure is exposure and I would assume It would be the same for any camera. For example if you meter your exposure with handheld meter (which is more accurate), you don’t have to specify the camera type. I think the exposure on different camera might be slightly different (should not be more then a stop) due to other factors, like lenses, accuracy of ISO manufacturer to manufacturer, etc. But new cameras getting better and better!
I would just test your camera and see. And remember, Sunny 16 is just your starting point.

That make sense Oksana,
