Re: IQ excellent, get the TC for long reach

You listed 300-400mm of FF-equivalent reach as a requirement.

The digital zoom is out - really, don't use it, because if you want to crop and upsample you can always do that at a computer in PP (and that's all the digital zoom does), with probably better quality (I generally don't upsample, so I can't judge) and more choices.

So for reach beyond 300mm equivalent, you want the 1.4x TC for the 40-150 PRO. That gives you an equivalent reach of 420mm - at f/4, generating a DOF equivalent of f/8 at f/4 exposure times.

With the TC, image quality remains excellent. Sharp from center to corner, with great microcontrast everywhere, no vignetting to speak of and great distortion control. The lens resolves high enough to not show any visible degradation with the TC attached. And the combo is perfectly hand-holdable.
