No, the 75-300 has better IQ than the 40-150. But it is slow lens (F4.8 - f6.7) and expensive (frequently on sale for $750), and somewhat large for m4/3 format.

For value, the 40-150 (frequently on sale for $99 -$149) is hard to beat. And it is small and has nice IQ, particularly 40-100 range. It has nice 'character' rendering.

The 75-300 is equal parts terrific and frustrating lens, with good sharpness, color and contrast, but takes practice for handholding, not good on tripod (no collar), and slow apertures are sometimes - not always - but sometimes a problem. For me, the tripod issues cause the most grief; when I give up and use it as a handholding lens, I really enjoy it.

In the end, I prefer the 75-300 over the 40-150 if I am shooting nature/wildlife, while preferring the much smaller 40-150 for city walks or travel.
