FT v MFT lenses

I think sometimes when discussing 4/3 lenses compared to m4/3 lenses people sometimes overlook that both sets of glass are designed and made for the same sized sensor. In other words, if one wants the design, speed and construction of say the ZD 12-60 in m4/3, they're going to get the ZD 12-60 with a m4/3 mount. It won't be smaller or lighter or faster or slower, it will be what Olympus has already designed for the 4/3 sensor.
