Currently the 2xTC is not available in Austria, but as I said I ordered one and will report back asap when I receive it.I will be interested in what both of you think of the 2x as I am somewhat conflicted about it. I have zero issues using the 1.4x -- to my eyes it is as good as the lens by itself in all areas. However with the 2x, I first see a tiny bit of IQ loss, arguably not enough to really matter for most images, but notable nonetheless. My bigger issue with it is what I see it does to bokeh; to my eyes it seems to clump it up --and rather significantly-- for lack of a better explanation.
For now it is the only option to get in the range of 400 with native glass. I was already pretty happy with the latest F mount combo some 8 years ago, so I assume / hope the S combo will be significantly better and that I would be a happy camper.
Anyway if I feel the need then I would get the 100-400 S whenever it arrives on the market. Or I may wait for the 200-600 although I have some concerns about it as it is not an S lens. Who knows ...
