Think about if you need the 40-100mm more than the 300-400mm range.

I have the 40-150mm F2.8 and both tele converters. The image quality 40-150 x2 is good, but I don't know if  it is better or worse than the 100-400mm at 300mm - I think only Oly has that knowledge right now. Maybe the 100-400 is better in the long end.

i have used that combo mostly for semi macro work so far, so the results are from close focus distances. With 1.4x I took some bird shots - no problem.

I changed the older 75-300mm lens for this combo to get a faster lens (F2.8 up to 150mm) and a reasonable light setup for hikes and travel. The IQ from 75-300 is quite good, but there is real difference between that and the 40-150, at least alone.

The 300mm is fine for larger animals, but with small birds it's a bit short - a 400mm would be better,  even 6.3. Remember, it's just 1/3 stop slower than F5.6... Not a big deal. The F-stop difference between 75-300mm (F6.7) and 40-150mm x2 (f5.6) is about the same. The 40-150 x 2 focuses faster than the 75-300.

However, if your main interest is travel photography, the 75-300 is hard to beat. It's so light and small that it fits to every bag.

I do think about getting the 100-400 for nature (birds)... But I'm not in a hurry...

Cheers!
