The reproduction ratio is just that, a ratio of the size of the original to the size of the image on the sensor (chemical or electronic). 1:1 means that a 10mm item is reproduced as a 10mm image by the lens, regardless of the size of the sensor. You are mixing up repro ratio language and field of view.

I think the multiplication factor works for that too. If the working distance were the same it would be producing the same size image as a 50 macro. Since you have a smaller sensor it will only capture a portion of that image. You will have to back up to get the smaller 1:1 image you are looking for.
