Those are as unexciting as their 14-150 superzoom for MFT. And with cameras like Panasonic FZ1000 or Sony RX10 on the market, I don't see slow superzooms for MFT making much sense.
I don't understand Tamron at all. There's a whole in the MFT system in regards to fast variable aperture zooms. There's another whole on the telephoto end. But no, they decided to make exactly the same superzoom as Olympus and Panasonic offers. And even price it the same.
I just don't get it. If they'd made a decent weather-sealed 12-50 or 12-60 with f/2.8-4.0 aperture, that would be a bestseller. Instead, we get another redundant lens, and some patents for even more fairly useless lenses. I doubt Tamron will get anywhere in MFT world. They'll probably give up on it after their first try, as I just don't see how their 14-150 could sell in any meaningful numbers.
