Seeing if there is anything out there that is affordable. Really wanting a good telephoto which i have in canon (70-200 f2.8II). My OMD is mostly for travel which i dont do much of but now have the opportunity to do but am missing the telephoto range since I only have the 12-40mm. Metabones just doesnt seem worth it for the price since I might as well plunk down the extra $ for the 40-150 f2.8 and doest the MB even AF? Kipon is cheap but seems shoddy. Anything else I may be missing?
