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.

I reread the DPR review of the Panasonic m4/3 7-14 and the comparison was with the Olympus M.Zuiko ED 9-18, not the ZD 7-14. Apparently Panasonic took some design shortcuts with their m4/3 7-14 that are corrected in camera (on Panasonic cameras only). The ZD 7-14 design doesn't use in camera correction, it is built with the corrections in the lens (hence the cost).

One advantage the m4/3 mount has (at the moment) is that it can take almost the entire M and LTM catalogue (less some of the wides), Zeiss, Canon, Nikon, Cosina and Leitz etc. And mount the HG and SHG catalogue.
