Like so many here, I got in on the QVC deal for the m.zuiko 40-150mm. Before buying it I was looking at the other zooms with more reach. I figured to be more sensible, bought the lens and figured to try my hand at a Teleconveter. primarily buying for a back country camping trip in a few weeks. I fear I'll get out there with the wildlife wishing I had more zoom. I'll be using this on a E-PL2. Can any one recommend a good T/C that doesn't degrade IQ significantly. Maybe its too much to ask. Thanks!
