How do you think the 40-150 with the 2x teleconverter would compare with the 75-300. Half a stop faster, but will image quality be better?

That's an interesting question. Actually it's just 1/3 of a stop and with a much more complex lens design the T-stop might be close to the same. And there's also the Panasonic 100-300 which is F5.6 at the long end.

But you will of course have a much better lens as long as you dont need to use the TC and maybe better IQ even with the converter. A 2x TC usually have an impact on IQ tough, but I haven't seen any real comparison yet.
