    I have seen and received comments from both Fotodiox and Sharpest Light that this is th Commlite adapter ( newest version) licensed to Fotodiox
    ( so is the Vello adapter )

    “It is too obvious that Commlite and Fotodiox adapters are exactly the same…..”

    Confirmed…this is the same Comlite/Vello adapter licenses to Fotodiox

    Contacted Fotodiox
    Will not work with teleconverters or 3rd party lense….probably not with long lenses either

    “It most like will not work with teleconverters, the AF will be most likely be hunting for ever, as for third party lenses they do worse then native lenses it varies from lens to lens but performance seems to be worse with them. “

    • Almost all adapters that aren’t first to market are rebranded or based on reverse engineering. Sometimes they have custom firmware etc… I am not surprised. Sometimes a few materials are changed in the manufacturing process. It really depends. The TechArt is by far my favorite adapter atm though. Pure mechanical is the way to go imo.
