    Need to get some help/info from the members here about purchasing a type of lens that I've been avoiding for a bit of a time now. I'm talking for a SP 70-200 f2.8 VC Canon mount from Tamron to go with the Sigma MC-11. That combo will click on my a7ii.
    Hope I'm on the right area with this post...:dash2:

    If you don't need f2.8 you can get the Sony 70-200 f4 for the same price more or less.

    Thanks for replying guys

    My fault did not made my self clear enough...I'm actually asking if the above combination is going to be good and working flawlessly with AFC , tracking, performance in low light AF and all the rest. I should say that I have tried the Sony 70-200f2.8 and was amazing ...also amazing was the price. Tried the latest Sigma 70-200 with the MC-11 straight after the Sony and I can't say that the performance gap justify the gap in price. The sales person thinks that the Tamron is better than the Sigma.

    F 2.8 is my target....like I wish my 16-35 was f2.8 and not f4

    Im not sure if A7II have that great AF that a6300, A6500 and A7RmkII have. I think af with la-ea3, mc-11 or other adapter will be significantly handicaped. I think you can buy A-mount version of tamron 70-200 2.8 and use it with la-ea4 with good AF but limited AF points.

    When I had the Sigma combo (70-200 f2.8 with MC-11) attached to my camera inside the shop with day light against the lens and poorly lit shop pointing in dark areas worked really well, half press the shutter always confirmed to the point I was targeting. I've turned the lens to a shop assistant and the green square was lock to the face and following him. From my perspective, I believe, the a7ii AF system is good and capable.

    Don't confuse A7RmkII with A7mkII as the first have superior autofocus.
