Need advice on 2X teleconvertors

[pixelate]

My Panasonic GH1 comes with the LUMIX G VARIO HD 14-140mm / F4.0-5.8 ASPH. / MEGA O.I.S. lens. Can I use it together with a 2x Teleconvertor so as to increase its Focal range to 280mm? Any recommendations? Thanks!!

I don't think Panasonic has any TCs to begin with. 3rd-party don't think so either. In any case, the HD14-140 is already such a slow lens. Assuming DSLR principles apply to mirrorless systems, adding a 2xTC (if you can find one), will slow it down even more by 2 stops and the AF might not work. And IQ will be compromised. If you need the range, why not get a longer lens, like the 100-300mm?
