  1. Hi,

    couldn’t find a proper place for the info I’m going to write so sorry.

    A Warning!

    Used my FE 1.4 TC with my 100-400 GM lens yesterday and found something “new” The lens can’t zoom back all the way to the 100mm mark. it stops a few mm before the endpoint with a rubber feeling and “bounces back” if one try to get further and let go of the zoom ring. Didn’t used any force but just slightly tried to move it. believe it’s the “rubber nose” of the TC that get hit by the end part of the lens.
    Checked the lens and TC but no marks/scratches on either that I could see.
    Take care if you use this combo and try to zoom out allt the way.
