New Oly 40-150 f/2.8 coming

Quote:You mean 56-210mm f/4 (or 112-420mm f/8 equiv).

A 2x converter for a zoom doesn't feel advisable.
 

Right, I was thinking 2x in my calculations for some reason.

It would indeed be a 112-420 f/8 FF equivalent lens, although it terms of speed it would still be f/4 though.

Perhaps a good quality 1.7x would be feasible and still lead to descent IQ?

That would make it a 68-255 f/4.8 (136-510 f/9.5 FF equiv)
