    Cons: Sigma needs to make it in Fuji XF mount and Olympus M43 mount and in Sony E mount.

    Pros: Super sharp wide open, very lightweight, great autofocus even when used with adapters.

    Summary: I bought this lens in Canon mount to use on my Sony A7R2 with the Sigma MC-11 adapter as well as on my Olympus E-M1 with the Kenko Canon-OlympusM43 Autofocus adapter. It works really well with both. I only wish it was made in native olympus and sony and fuji mounts. I am certain this lens is sharper on the E-M1 than the panasonice 100-400 and I think Sigma is missing a key market there. It is even just as light and small as the Panasonic lens. I really wish lenstip would test this lens with one of the Sigma teleconverters as I wonder how sharp it would be with a 1.4 teleconverter compared to the sigma 150-600 lenses.
