Switch completely to m43. I love my Canon 100-400mkll too much. I've looked at the Olly and Panny range of lenses and despite what many have said, and from the images that I have seen, I don't think that they stack up to my Canon, despite being more expensive. That said, I would still like to invest more in the Olympus m43 system as I like the (lack of) weight, the focus bracketing/stacking and other features. I have two ME10's mk l and mk ll and am thinking about buying a metabones T Adapter so that I can utilise the Canon lens. I also like the fact that it would give me a reach of 800mm and even more with my 1.4 extender.
Has anyone used this combination and what are your impressions?
