So with all of the other threads going on about "effective" this and that, and how framing and DoF change vis a vis sensor size, i figured I would get confirmation on something that we all should agree on. If a lens is designed for film, and it is displaying a max macro capability of 1:2, putting it on a m4/3 sensor does not magically transform it into a 1:1. It is still half the size of the original, there is just less of the original surrounding on the sensor, due to the smaller size. I have seen tons of people advertising that if you take a 1:2 macro (for FF) and put it on a m4/3 sensor, it magically makes it 1:1. If I take that lens, and put it on my m4/3 camera, I will still only get ~9mm (17.3/2 taking up the whole frame, as opposed to ~18mm (35.8/2). Yet it is still represented at half of the actual size on the sensor itself. Macro is an inherent property of the lens itself, like focal length and aperture size, not a function of sensor size. Correct? Comments? Concerns?
