Has anyone done some test to compare the Olympus 75-300mm II at 300mm, against the 40-150mm f/2.8 + 1.4x teleconverter at 210mm cropped to match the former?

I currently have a 75-300mm II and I'm looking to replace it with a faster lens. I have the budget for the Olympus 300mm f/4, but I think the 40-150mm f/2.8 can be more useful for me overall. Just when to know what I should expect from the 40-150 + TC, and if I would really lose any reach.


When I first started my conversion to Olympus I used a Canon FD 400mm ƒ4.5 on my EM5.  This worked pretty well but I decided I wanted AF so I got the 75-300 to use.  It was decent lens for what it was but I thought beyond 250mm it was soft and never used it pass 280mm because of the softness.  After playing with this combo for awhile I had decided I wanted to make a bigger commitment to µ4/3 and bought the EM1 and the 50-200 SWD (as well as the EC-14) to use as my wildlife lens until the 300mm ƒ4.0 Pro was released.  Went this route because there is little difference in IQ between the 50-200 and 40-150 Pro and the extra reach was really nice to have.

If you had an EM1 I would recommend the 50-200 with both the EC-14 and EC-20 if budget is a concern.  Since you are using the EM5 I would get the 40-150 and TC.
