I have been very close to purchasing TWO lenses: the Olympus TC 1.4x, and the 40-150 F2.8. I own the Olympus 100-400mm zoom, and I also own the 50-200 with 1.4x TC, and the adapter to mount this 4/3 on to a MFT mount. The 40-150 f2.8 gets wonderful reviews.
But how does it compare to using the 50-200 4/3 lens adapted to fit on a current MFT body? And is getting a 1.4 x TC and the "new" focal length for my 50-200 is 70-280mm. Has anyone tested/compared these two lenses? The 50-200 is a very sharp lens; will the 40-150 f2.8 be as sharp, or sharper?
And can you really make use of the 1.4 TC on the 100-400? I do not need the 1.4 TC for the lower range lens; but can you really shoot at 560mm or more (equivalent to over 1000mm full frame 35mm??)
